Abstract
A wig (10, 30) is made with artificial hairs (12, 13, 32, 33)
having bending rigidities depending upon portions attached to
respective portions. A wig base (11, 31) is partitioned to a
plurality of regions, and the hair (12, 32) having bending rigidity
lower than average natural hair is attached to the periphery (11a)
of the left and right side head portions and the rear head portion
and to the total peripheral region (31A), and blended with the
wearer's own hair growing around the wig. On the other hand, in the
region toward the center of the wig base (11, 31), the hair (13,
33) having bending rigidity of the same level as natural hair is
attached. The artificial hair (12, 13, 32, 33) has the
pre-determined length and curl diameter depending upon respective
regions, and especially, the hair (13) to be attached to the
peripheral portion (11a) and the hair (33) to be attached to the
total peripheral region (31A) have the curl diameter and/or length
of substantially the same level as the hair growing on the wearer's
scalp.

Description
TECHNICAL FIELD
[0001] This invention relates to a wig such that its wearing is not
easily visible by controlling the bending rigidity of the hair
attached to its wig base for the better blending with the wig
wearer's own hair growing on the scalp.
BACKGROUND ART
[0002] A wig comprises basically in general a wig base with a net
material as its main part or a wig base of an artificial skin made
of a thin sheet or film of polyurethane or silicone, and hair
attached to said wig base by sewing or bonding. As the hair
attached to a wig base, besides natural hair such as human hair,
the artificial hairs made of polyamide resins, polyester resins, or
modacryl are known. As the types of wigs, the cap-shaped wig for a
whole scalp which has a periphery along the wearer's hairline on
the forehead, side head, and rear head portions, and the partial
wig to be worn to hide only the necessary portion of the head are
known in general.
[0003] Patent Reference 1 discloses that various hair styles are
available by partitioning a scalp to a plurality of portions,
wearing partial wigs on respective portions, and exchanging a part
of the plurality of partial wigs with other partial wigs, changing
the positions for wearing on the scalp, or by changing the
direction of wearing.
[0004] Natural hair has been fondly used since ancient times as the
hair attached to a wig base as mentioned above, but there are many
cases recently that, from restriction of supply of natural hair
material, acrylic, polyester, polyamide synthetic fibers, for
example, are used as the hair material for a wig. For example,
since polyamide fibers have appearance and physical properties
similar to natural hair in many aspects, they have so far been in
practical use, and especially, excellent wigs can be provided by
the invention of the present applicant which removes unnatural
gloss by surface treatment (See Patent Reference 2.).
[0005] On the other hand, polyacrylic fibers have low melting point
and poor heat stability, so that they have such weak points as poor
shape preservation after permanent wave setting, resulting in
distortion of setting, for example, such as curl and the like when
disposed in warm water. Polyester fibers excel in strength and heat
stability, but have too high bending rigidity, in addition to
extremely low moisture absorbency compared with natural hair,
resulting in appearance, tactile feeling, or physical properties
different from natural hair, for example, in the environment of
high humidity, and they give markedly uncomfortable feeling when
used for wigs. This bending rigidity is defined as the reciprocal
number of curvature change generated when a unit bending moment is
applied to artificial hair. The larger the bending rigidity of
artificial hair, the less bendable, the more resistant to bending,
that is, the harder and the less bendable is artificial hair. In
other words, the smaller the bending rigidity, the more bendable
and softer is artificial hair.
[0006] Said bending rigidity is the property relating to such
feeling as tactile and texture of fibers, and is widely recognized
in fiber and textile industries as such that capable of numerical
expression by KAWABATA method of measurement (See Non-Patent
Reference 1.). Also, an apparatus has been developed which can
measure the bending rigidity using a single strand of fiber or hair
(See Non-Patent Reference 2.).
[0007] Polyamide fibers include linear saturated aliphatic
polyamide in which only methylene chains are connected with amide
bond as a main chain, for example, such as nylon 6 and nylon 66,
and semi-aromatic polyamide in which phenylene units are included
in the main chain, for example, such as nylon 6T of TOYOBO, LTD.
and MXD6 of MITSUBISHI GAS CHEMICAL COMPANY, INC. Patent Reference
2 discloses surface-treated artificial hair of nylon 6 fiber as the
material, but only nylon 6 fiber has the bending rigidity lower
than natural hair as the property relating to such feeling as
tactile and texture, and hence it is difficult to manufacture the
artificial hair of the same property as natural hair. Here,
although the above-mentioned "nylon" is a trademark of du Pont,
since the Examples of the present invention used "nylon" as
polyamide fibers, this term will be used throughout the present
specification.
[0008] On the other hand, the artificial hair using nylon 6T has
the bending rigidity higher than the natural hair, and hence it is
difficult to manufacture the hair of the same property as natural
hair. Therefore, it might be considered to manufacture the fiber
having the bending rigidity close to natural hair by melt-spinning
of nylon 6 and nylon 6T, but these two resins have too different
melting points, and if melt temperature is determined fitting to
nylon 6T of higher melting point, then there is too serious a
problem in the manufacturing process that nylon 6 having low
melting point and relatively poor heat stability is deteriorated by
thermal oxidation during melting and, consequently, excellent
artificial hair can not be obtained.
[0009] The fiber of sheath/core structure is known as the method to
utilize both properties of two kinds of resins. Said fiber
comprises a core fiber and a sheath fiber surrounding it, and has
been reported as a generic fiber, or artificial hair material for
wigs, by utilizing respective properties of different two kinds of
resins. (See Patent References 3 and 4.) Patent Reference 3
discloses the fiber of sheath/core structure made of vinylidene
chloride, polypropylene, and others, and Patent Reference 4
discloses a polyamide, but modified fiber by blending protein
bridged gel into the core part.

DISCLOSURE OF THE INVENTION
Problems to be Solved
[0016] When a partial wig is worn on the wearer's scalp to cover
the thin hair portion, it is important to have physical properties
mutually close as much as possible between the wearer's own hair
and the artificial hair of the wig so that the wearer's own hair
growing around the thin hair portion and the artificial hair
attached to the wig blend well without apparent separation. Hence,
artificial hair used for a wig is primarily required to have
feeling close to natural hair (appearance, ductile and texture
feeling) and physical properties, and, in addition, ideally to have
physical properties superior to natural hair. As mentioned above,
various synthetic fiber materials have their own merits and
defects, and, among them, certain polyamide fibers are now in
practical use owing to their excellent properties.
[0017] However, when a wig is made by attaching artificial hair
made of a polyamide fiber material to a wig base, since bending
rigidity of a polyamide fiber is too low compared with the wearer's
own hair even if the wearer's own hair growing on the scalp and the
artificial hair attached to a wig base are well blended and the
hair style is well set upon the wig wearing, the wearer's own hair
and the artificial hair attached to a wig are separated as time
elapses since the wig wearing, the wearer's own hair around the wig
base periphery stands up to cause unnatural style, resulting in
easily visible wig wearing. On the contrary, in case of polyester
fibers of high bending rigidity compared with natural hair, the wig
hair stands up unnaturally, not well blended with the wearer's own
hair and is separated. Therefore, the border of the wearer's own
hair and the wig hair possibly appears to make wig wearing
visible.
[0018] Also, if the hairs attached to a wig base are arranged in
the same lengths regardless of the region of the wig base, or have
a curl diameter different from that of the wearer's own hair, then
the hairs of the wig can not be well shaped as a whole, and it
takes time to set a hair style after the wig wearing.
[0019] An object of the present invention is, in view of the
above-mentioned problems, to provide a wig which does not easily
separate the wearer's own hair growing on the scalp and the hair
attached to the wig, and which does not easily make the wig-
wearing visible by well blending.
[0020] Another object of the present invention is to provide a wig
which makes it possible for the wearer to easily set a desired hair
style, and not to easily distinguish the wearer's own hair growing
on the scalp and the hair attached to the wig.
Means to Solve Problems
[0021] As the result of the present inventors' strenuous study, it
was confirmed that a person who needs a wig has the hair growing on
the scalp which in general lacks toughness and is soft, and also
the wearer's own hair growing around the thin hair portion such as
a side head or a rear head portions has similarly low bending
rigidity, and developed artificial hair whose deformation to the
bending strength, that is, bending rigidity is controlled to the
same level as natural hair by adopting a sheath/core structure
wherein the core is made of high rigidity polyamide fiber and the
sheath is made of the polyamide fiber of lower rigidity than the
core. The present invention thus further improved this novel
artificial hair, as well as completed a wig which gives natural
appearance as if the wearer's own hair grew on the scalp when
attached to a wig base.
[0022] In order to achieve the above-mentioned object, one of the
embodiments of the present invention is a wig comprising a wig base
and hair attached to the wig base, characterized in that the hair
attached to at least a periphery of said wig base has bending
rigidity lower than natural hair.
[0023] Another embodiment of the present invention is that the wig
base is partitioned to a plurality of regions including a periphery
of a left and right side head portion and a periphery of a rear
head portion, the hairs attached to the partitioned regions of the
wig base have bending rigidities pre-determined for the respective
regions, and the hairs attached to said periphery have bending
rigidities lower than natural hair.
[0024] In the above-mentioned makeup, in the region closer to a top
portion as the center region of the wig base among the partitioned
regions of the wig base, the hair of higher bending rigidity than
the hair attached in a periphery is preferably attached.
[0025] Said wig base is partitioned including at least a top
portion as the center region of the wig base, the periphery, and an
intermediate region zoned between the top portion and the periphery
along said periphery, the hair attached to the top portion may have
bending rigidity of substantially the same level as natural hair,
the hair attached to the periphery may have bending rigidity lower
than natural hair, and the hair having bending rigidity of
substantially the same level as natural hair and the hair having
bending rigidity lower than natural hair may be mixed and attached
to the intermediate region. The hairs attached to the partitioned
regions of said wig base preferably have curl diameters and/or
lengths pre-determined for the respective regions, and the hairs
attached to said peripheries preferably have curl diameters and/or
lengths of substantially the same level as the wearer's own hair
growing on the scalp.
[0026] A wig of another embodiment of the present invention is
characterized in that the wig base is partitioned to a plurality of
regions including the total peripheral portion comprising a
periphery of a forehead portion, a periphery of a left and right
side head portion, and a periphery of a rear head portion, the
hairs attached to the partitioned regions have bending rigidities
pre-determined for the respective regions, and the hairs attached
to the total peripheral portion have bending rigidities lower than
natural hair.
[0027] Said regions are preferably partitioned including a top
portion as the center region of the wig base, the total peripheral
portion comprising the periphery of the forehead portion, the
periphery of the left and right side head portion, and the
periphery of a rear head portion, and an intermediate region zoned
between said top portion and said total peripheral portion along
said total peripheral portion, the hair attached to the top portion
has bending rigidity of substantially the same level as natural
hair, the hair attached to the total peripheral portion has bending
rigidity lower than natural hair, and the hair having bending
rigidity of substantially the same level as natural hair and the
hair having bending rigidity lower than natural hair are mixed and
attached to the intermediate region.
[0028] In the above-mentioned makeup, preferably the hairs attached
to the partitioned regions of the wig base have curl diameters
and/or lengths pre-determined for the respective regions, and the
hair attached to the total peripheral portion has a curl diameter
and/or length of substantially the same level as the wearer's own
hair growing on the scalp.
[0029] Hair preferably has a sheath/core structure comprising a
core portion and a sheath portion covering said core portion, the
core portion is made of a polyamide resin, the sheath portion is
made of a polyamide resin having lower rigidity than the core
portion, and bending rigidity is controlled by the mass ratio of
the sheath portion and the core portion.
[0030] Alternatively, hair may be made by mixing a first artificial
hair made of a polyamide resin and a second artificial hair made of
a polyester resin in the pre-determined ratio, the first artificial
hair has a sheath/core structure comprising a core portion and a
sheath portion covering said core portion, the core portion is made
of a polyamide resin, the sheath portion is made of a polyamide
resin having lower rigidity than the core portion, and bending
rigidity is controlled by the mass ratio of the sheath portion and
the core portion.
[0031] The wig of the present invention is such that the hair
attached to the periphery of the wig base has bending rigidity
lower than natural hair, and the wearer's own hair growing on the
scalp has bending rigidity equal to or lower than natural hair, so
that, with the hair having bending rigidity of the same level as
the wearer's own hair attached to the left and right side head and
the rear head peripheries of the wig base, said hair and the
wearer's own hair are well blended and both show similar standing
up and curvature. Therefore, the wearer's own hair and the wig hair
do not separate to show similar behavior. Also, since the hair
having length and/or curl diameter pre-determined for each wig base
region is attached in the wig of the present invention, only
partial fine adjustment is required upon wearing said wig, and
hence the hair style can be easily formed according to the wearer's
preference.
[0032] As the hair attached to the wig base, the hair whose bending
rigidity is controlled can be used by adjusting the mass ratio of a
sheath/core structure with polyamide materials, adjusting the
cross-sectional size with polyester materials, or adjusting the
mixing ratio of polybutylene terephthalate as the incorporated feed
material.
Effect of the Invention
[0033] Generally speaking, the wearer's own hair growing on the
scalp, that is, the remaining hair growing around except for the
lost hair and the thin hair portions has bending rigidity lower
than natural hair on average. According to the present invention,
since the hair attached to the periphery of the wig base has
bending rigidity lower than natural hair, as a result, the hair
having bending rigidity of the same level as the wearer's own hair
growing on the scalp is attached to the wig base periphery or the
total peripheral region. Therefore, when the wig is worn, and the
hair attached to the periphery or the total peripheral region is
put over the neighboring wearer's own hair and blended therewith,
the wig hair and the wearer's own hair show similar behavior,
mutually blend well, and are not easily separated. Therefore, wig
wearing is not easily visible.
[0034] According to the present invention, if the wig base is
partitioned to a plurality of regions including the periphery and
the total peripheral region, and hair of a different bending
rigidity is attached to each region, then the hair style can be
formed which has such bulky feeling that a wearer has so far never
accomplished. If the hair attached to the wig base periphery or its
total peripheral region has curl diameter or length of about the
same level as the wearer's own hair, then the wearer's own hair
tends to blend well with the wig hair, and wig wearing is
furthermore not easily visible. In addition, the hair style can be
easily formed in short time according to the wearer's preference
only by simple adjustment.

BEST MODE FOR CARRYING OUT THE INVENTION
[0077] Hereinafter, the present invention will be explained with
reference to some preferred embodiments illustrated in the
figures.
[0078] FIG. 1 schematically illustrates a state of wearing the wig
10 of the present invention on the wearer's scalp. The wig 10 of
the present invention is so constituted that hair 12 and 13 is
attached to a wig base 11. Especially, artificial hair 12 and 13 is
attached to each portion of the wig base 11 with preferred bending
rigidities adjusted for respective portions. The wig base 11 is
partitioned to a plurality of regions, and in said wig base 11,
hair 12 of bending rigidity lower than natural hair is attached to
the periphery of the left and right side head portions and to the
periphery 11a of the rear head portion. On the other hand, in the
region toward the top portion except for the periphery 11a of the
wig base 11, hair 13, for example, having bending rigidity of about
the same level as natural hair is attached.
[0079] Here, the bending rigidity is the property relating to such
feeling as tactile and texture of fibers, as mentioned in the
section of Background Art in the present Specification, defining
the magnitude of force required to bend fiber, that is, the force
applied to fiber for bending it, and the higher this value is, the
harder is the fiber and more difficult to bend. The bending
rigidity mentioned in the present Specification is measured by the
above-mentioned KAWABATA method of measurement.
[0080] When a wig 10 is worn with such a distribution pattern of
bending rigidity of the attached hair, the hair 12 attached to the
wig periphery 11a is arranged so as to cover the wearer's own hair
1 growing next to the wig. Therefore, the wig hair 12 having
bending rigidity of about the same level as the wearer's own hair 1
and said wearer's own hair 1 can be blended well by brushing.
Generally speaking, a partial wig 10 is made in size to hide the
thin hair or the lost hair portion, and, referring to FIG. 1, the
wearer's own hair 1 growing near the thin hair or the lost hair
portion around a forehead and a top portions as the center, for
example, the wearer's own hair 1 growing on left and right side
head and a rear head portions has low bending rigidity in general
compared with ordinary natural hair. Therefore, when the hair 12 of
bending rigidity lower than that of natural hair is attached to a
wig base periphery 11a, since the hair 12 has bending rigidity of
the same low level as that of the wearer's own hair 1 growing next
to the partial wig 10, the wig hair 12 and the wearer's own hair 1
can be well blended. Here, the wig hair 12 may have bending
rigidity more or less lower than that of the wearer's own hair 1.
Even if bending rigidity is more or less lower than that of the
wearer's own hair 1, since the wig hair 12 is located upstream of
the wearer's own hair 1, it is so arranged as to cover the wearer's
own hair 1, resulting in properly blending by brushing and the
blurred border of the wig hair 12. However, if bending rigidity of
the wig hair 12 is too low compared with the wearer's own hair,
then it is not suitable because the border becomes visible.
[0081] In FIG. 2 as the plan view of the wig base 11 of a typical
partial wig, the direction of an arrow mark shows that of the front
side of the wig, that is, the direction of the wearer's sight. The
wig base 11 is constituted with a net base or an artificial skin
base or by their combination depending upon the shape and the size
of the wearer's head and also upon the distribution and the amount
of the wearer's own hair 1. At least on the periphery 11a of the
left and right side head and the rear head portions of the wig base
11, the hair 12 having bending rigidity lower than that of natural
hair is attached. (See FIG. 1.) On the other hand, the hair 13 to
be attached to the other regions, that is, the region up to a
center portion other than the periphery 11a preferably has bending
rigidity of the same level as that of natural hair. Thereby, the
desired hair style can be attained which so far could not be
attained with the wearer's own hair.
[0082] FIG. 3(A) is a view schematically illustrating the wig 10 of
the present invention, and FIG. 3(B) is a view schematically
illustrating the wig 20 as Comparative Example, respectively. The
wig 10 of the present invention, as shown in FIG. 3(A), is such
that the hair 12 attached to the periphery 11a of the left and
right side head and the rear head portions of the wig base 11 has
bending rigidity lower than that of natural hair. Therefore, only
the hair attached to the periphery 11a does not stand up by combing
and well blending the wearer's own hair 1 and the hair 12, and
further the wearer's own hair 1 and the hair 12 are not separated
and both can not be distinguished, so that wig wearing is hardly
visible.
[0083] Here, the wearer's own hair is soft and has low bending
rigidity in general compared with a person's own hair who does not
need a wig. Therefore, as shown in FIG. 3(B), if the hair 22
attached to the periphery 21a of the left and right side head and
the rear head portions of the wig base 20 has higher bending
rigidity than that of the wearer's own hair 1, the hair 22 attached
to the wig base periphery 21a tends to stand up easily, and since
the wearer's own hair 1 next to it lies down, the hair 22 and the
wearer's own hair 1 have different hair line and show different
behaviors respectively. Therefore, the border line of the wearer's
own hair and the wig hair covering it appears linearly in the
horizontal direction, and hence wig wearing tends to be
visible.
[0084] Explanation is made here of a wig base in the wig of the
present invention. Several kinds exist as wig base shapes and their
virtual partitions. For example, they are roughly classified to a
front hiding type to be adopted when the wearer's whole head is
thin-haired, and to a top wearing type to be adopted when the top
region in the wearer's head is partially thin. The former front
hiding type is that corresponding to a retreating hair line,
whereas the latter top wearing type is that corresponding to a
person whose hair line does not retreat but the portions around the
top are partially thin, and also the type particularly responding
the desire to increase hair by fashionable sense. Comparatively,
the former is desired by male customers while the latter by female
customers.
[0085] FIG. 4 is a view illustrating as an image the state of
wearing the wig 10 including a front hiding type wig base 11 on the
wearer, wherein (A) is a diagonal view of wearing state, and (B) is
a plan view of wearing state. In FIG. 4(A), only the parts of the
wearer's own hair 1 and the hair 12 and 13 are shown, and in (B),
the wearer's own hair 1 and the hair 12 and 13 are not shown. The
front hiding type wig base 11 is such that, as shown in FIG. 4, the
whole periphery of the wig base 11 is constituted with a forehead
portion 11b thrusting from the top to the front side so as to cover
a part of the wearer's forehead and the periphery 11a formed with
the periphery of the left and right side head and the rear head
portions in the region around the lost hair portion of the wearer,
and since the curvature of the periphery 11a is larger than that of
the forehead portion 11b, a turning point 11D fitted to the shaved
portion 2 to be present there is formed.
[0086] FIG. 5 is a view illustrating as an image the state of
wearing the wig 30 including a top wearing type wig base 31 on the
wearer. As for the top wearing type wig base 31, it is worn on and
near the top of the wearer's head.
[0087] FIG. 6 is a plan view schematically illustrating the wig
base 11 of the front hiding type. Said wig base 11 is partitioned
to a plurality of regions by virtual lines, and the direction of an
arrow mark shows that of the front side of the wig. As shown in
FIG. 6, said wig base 11 is constituted about symmetrically to the
left and the right according to the shape and the size of the
wearer's head, and virtually partitioned to a forehead portion 11b
corresponding to a head front with the attached forelock, a top
portion 11c zoning a center region of the wig base 11 and
corresponding to the head top, the about U-letter shaped first belt
portion 11d neighboring the left and right and the rear ends of the
top portion 11c, a second belt portion 11e neighboring the left and
right and the rear ends of the first belt portion 11d and the left
and right ends of the forehead portion 11b, and a peripheral
portion 11a neighboring the left and right and the rear ends of the
second belt portion 11e except for the forehead portion and hemming
the left and right side head and the rear head portions of the wig
base 11.
[0088] Namely, said wig base 11 is partitioned to a top portion
11c, a forehead portion 11b on its front side, a first belt portion
11d, a second belt portion 11e, and a peripheral portion 11a zoned
at three steps in about a U-letter shape from the top portion 11c
to the rear and the left and right side head portions. The top
portion 11c neighbors the forehead portion 11b at its front end and
neighbors the first belt portion 11d at its left and right and the
rear ends. The about U-letter shaped belt-like second belt portion
11e partially surrounds the forehead portion 11b and the first belt
portion 11d from the left and right and the rear ends. The
peripheral portion 11a neighbors the outside of the second belt
portion 11e, that is, the left and right and the rear ends, and
hems the left and right side head and the rear head portions of the
wig base 11.
[0089] Thus, the wig base 11 of the front hiding type shown in FIG.
6 is partitioned to five regions for attaching hair of a curl
diameter and/or a length pre-determined for each region. The reason
for it is as described below. Since the forehead portion 11b is the
most visible region to the third party besides the wearer, it is
extended in the left and right directions from the left and right
symmetry line of the forehead portion 11b, and covers the wearer's
shaved portion 2 to be present. The top portion 11c is an important
region to affect the wearer's hair style and appearance and the
impression to the third party. The peripheral portion 11a is
extended from the rear to the left and right side heads to be about
U-letter shaped, wherein the hair is attached which is well blended
with the wearer's own hair 1, and thus it is the region for
preventing exposure of wig wearing. The wig of the present
invention is, as described below, such that when constituted with
the hair of the pre-determined curl diameter and/or length attached
to each region, if the hair of different curl diameter and/or
length is attached to the forehead portion 11b, the top portion
11c, and to the peripheral portion 11a, then notches are formed at
respective borders due to the differences of curl diameters and
lengths. Especially, between the top portion 11c and the peripheral
portion 11a, a notch tends to be formed easily because the attached
hairs are not well blended. Therefore, a first belt portion 11d is
zoned at the outer hem of the top portion 11c as a buffer region at
the top portion side, and a second belt portion 11e is zoned at the
inner hem of the peripheral portion 11a as a buffer region at the
peripheral portion side. Thereby, even if the hairs attached to the
peripheral portion 11a and to the top portion 11c have a difference
in a curl diameter and/or a length, the hair having an intermediate
curl diameter and/or length of the hairs attached respectively to
the peripheral portion 11a and to the top portion 11c can be
attached step-wise to the first and the second belt portions 11d
and 11e, respectively, and hence notches are not formed in the hair
attached to the wig base 11. With the hair attached to the
peripheral portion 11a further having a curl diameter and/or a
length of about the same level as those of the wearer's own hair
growing on the scalp, only such fine adjustment may be required as
partial hair cut upon wearing said wig, and the hair style which
the wearer prefers can be formed easily and in short time.
[0090] FIG. 7 is a plan view illustrating the manner in which the
wig base is partitioned to three regions on the 5-partitioned
regions in the wig base shown in FIG. 6. The wig base 11 of the
front hiding type as shown in FIG. 6 is partitioned to three
regions as shown in FIG. 7 for attaching the hairs of different
bending rigidities. Partitioning to three regions is determined
based on the 5-partitioned regions shown in FIG. 6. Namely, the wig
base 11 shown in FIG. 6 is 5-partitioned to the forehead portion
11b, the top portion 11c, the first belt portion 11d, the second
belt portion 11e, and the peripheral portion 11a for attaching the
hairs of curl diameters and/or lengths pre-determined for
respective regions, and for having the pre-determined bending
rigidities and for attaching the hairs of the pre-determined curl
diameters and/or lengths, it is partitioned to three regions based
on the 5-partitioned regions, the main region 11B including the
first belt portion 11d from the forehead portion 11b to the top
portion 11c, the region 11A of the peripheral portion 11a, and the
adjustment region 11C between the main region 11B and the
peripheral portion 11A.
[0091] The reason why the regions are partitioned to three for
attaching hairs of different bending rigidities is explained below.
As described above, the forehead portion 11b and the top portion
11c are the most visible regions to the third party other than the
wearer himself, and are the very important regions which determine
the wearer's hair style, appearance, and the impression to the
third party. The peripheral portion 11a is the region where the
hair to be blended with the wearer's own hair 1 is attached to
prevent the exposure of wig wearing. In the present invention,
since the wig base 11 is constituted by attaching hairs of
different bending rigidities in respective regions, if, not
providing an adjustment region 11C, hairs of different bending
rigidities are attached respectively to the main region 11B
comprising the top portion 11c of the wig base 11, the forehead
portion 11b neighboring it, and the first belt portion 11d, and the
region 11A of the peripheral portion 11a ("the peripheral region"),
then hair stands up differently from the wig base 11 due to the
difference of bending rigidities at the respective border of the
main region 11B and the peripheral region 11A. Therefore, the hairs
attached to the main region 11B and the peripheral region 11A,
respectively, are not well blended and cause a notch. Especially,
the hair of the bending rigidity of the same level as that of
natural hair is attached to the main region 11B from the forehead
portion 11b to the top portion 11c, as described later, for
generating bulky feeling in the whole hair, whereas the hair of
lower bending rigidity than the average natural hair is attached to
the peripheral region 11A. In this case, if the hair attached to
the main region 11B flows backward and sideward, the hair attached
to the peripheral region 11A all the more stands up without lying
along the scalp. Therefore, an adjustment region 11C is provided
between the main region 11B and the peripheral region 11A from the
forehead portion 11b to the top portion 11c. Said adjustment region
11C corresponds to the region of the second belt portion 11e shown
in FIG. 6. Thus the wig base 11 is partitioned to three
regions.
[0092] If the hairs attached to the peripheral region 11A and to
the main region 11B have different bending rigidities, the notch
due to the hair attached to the wig base 11 is no longer caused by
attaching the hair of the intermediate value of the respective
bending rigidities of the hairs attached to the peripheral region
11A and to the main region 11B to the adjustment region 11C
provided between the peripheral region 11A and to the main region
11B. Therefore, when a wig 10 is worn, wig wearing is hardly
visible because the wearer's own hair 1 and the hair 12 attached to
the peripheral region 11A of the wig base 11 are not separated, and
the hair border is not caused due to the difference of bending
rigidities within the wig base 11.
[0093] As explained above, the front hiding type wig base 11 shown
in FIG. 6 is partitioned to five regions for attaching hair of the
pre-determined curl diameter and/or length to respective regions.
However, only by changing the curl diameter and/or length of the
attached hair, the hair style of bulky appearance can not be
created. Therefore, as shown in FIG. 7, by rearranging three
regions based on the five regions of the wig base 11, and attaching
the hairs of different bending rigidities to the three partitioned
regions, respectively, the wearer's desired hair style can be
further formed together with the effect of the hair of the curl
diameter and/or length determined to the five partitioned regions,
respectively.
[0094] Here, the wig base 11 is designed to have a proper size
depending upon the wearer's head shape and size and the lost hair
or thin hair state, and by designing the length L.sub.1 on the
center axis of the forehead portion 11b, the length L.sub.2 between
the left and right ends, the width L.sub.3 of the first belt
portion 11d, the width L.sub.4 of the second belt portion 11e, and
the length L.sub.5 of the peripheral portion 11a to the
pre-determined values, and properly adjusting the size of the top
portion 11c, the size of the wig base 11 is designed to fit the
wearer's head size. Here also, in the present specification, the
lengths and widths are those along the curved surface of the wig
base 11, including those indicating the size of the wig base
11.
[0095] It is necessary to arrange substantially equally the
respective regions of the wig base 11, that is, the forehead
portion 11b, the top portion 11c, the first belt portion 11d, the
second belt portion 11e, and the periphery portion 11a, regardless
of the sizes of the wig wearing regions on the wearer's head.
Explanation is made of the case where the size of the wig base 11
is larger than a certain level. That the size of the wig base 11 is
larger than a certain value means, for example, the front to the
back length L of the wig base 11 is 15 cm or more, and the left and
right length D is 15 cm or more. The size of the top portion 11c is
determined for each wearer, taking into consideration the wearer's
head shape and size, its lost hair state, or others. The peripheral
portion 11a of the wig base 11 is zoned belt-shaped of
substantially U-letter shaped with its width L.sub.5 of 2 cm at the
center on the left and right symmetrical line. The forehead portion
11b has the width of 5 cm from the front to the back L.sub.1 at the
center on the left and right symmetrical line, and is zoned to have
narrower front to back width toward both ends to the left and right
as the front to back width L.sub.2 of 3 cm of the side portion
neighboring the second belt portion 11e to the left and right. The
first belt portion 11d is zoned belt-shaped substantially U-letter
shaped along the inner periphery of the second belt portion 11e to
have the width L.sub.3 of 1.5 cm at the center on the left and
right symmetrical line. The second belt portion 11e is zoned
belt-shaped substantially U-letter shaped along the inner periphery
of the peripheral portion 11a to have the width L.sub.4 of 1.5 cm
at the center on the left and right symmetrical line.
[0096] Explanation is made of the above-mentioned widths L.sub.1 to
L.sub.5 values.
[0097] It is necessary to flow a part of the hair attached to the
forehead portion 11b in the forward direction for preventing the
visibility of the hair border line, and also necessary to flow it
in the directions to the top portion 11c, the first belt portion
11d, the second belt portion 11e and the peripheral portion 11a
neighboring the forehead portion 11b in order not to cause a notch
even though attaching the hair of different bending rigidities to
the wig base. Therefore, if the width from the front to the back
L.sub.1 on the left and right symmetrical line of the forehead
portion 11b is less than 5 cm, then it will be difficult to flow
the hair attached to the forehead portion 11b in the forward
direction, and at the same time in the directions to the top
portion 11c, the first belt portion 11d, the second belt portion
11e and the peripheral portion 11a. Consequently, the hair border
becomes exposed, a notch is caused in the whole hair attached to
the wig base, resulting in the not preferable exposure of wig
wearing. On the other hand, if the width from the front to the back
L.sub.1 is larger than 5 cm, first of all, the region of the
forehead portion 11b is too wide, causing unnatural feeling to the
third party other than the wearer with the extremely visible
forehead portion 11b. Second of all, the region of the top portion
11c becomes small, and a hair style desired by the wearer can be no
longer formed. Therefore, the width from the front to the back
L.sub.1 on the left and right symmetrical line of the forehead
portion 11b is preferably 5 cm.
[0098] If the width from the front to the back L.sub.2 on both
sides of the forehead portion 11b neighboring the second belt
portion 11e is less than 3 cm, then the hair attached to the
forehead portion 11b and those attached to the top portion 11c, the
first belt portion 11d and the second belt portion 11e can not
blend well, and, in addition, when the hair attached to the
forehead portion 11b is combed to the front and the back and to the
left and right, it is not preferable because the turning point 11D
is visible from outside, and wig wearing is exposed. Therefore, the
width from the front to the back L.sub.2 on both sides of the
forehead portion 11b neighboring the second belt portion 11e is 3
cm. If said width from the front to the back L.sub.2 is equal to or
longer than the width from the front to the back L.sub.1 on the
left and right symmetrical line of the forehead portion 11b, then
the region of the first belt portion 11d becomes narrow, and wig
wearing is visible from outside, as the notch is caused with the
hair attached to the first belt portion 11d and the hair attached
to the top portion 11c being separated, and hence it is not
preferable.
[0099] Explanation is made of the width L.sub.3 on the left and
right symmetrical line of the first belt portion 11d, the width
L.sub.4 on the left and right symmetrical line of the second belt
portion 11e, and the width L.sub.5 on the left and right
symmetrical line of the peripheral portion 11a. FIG. 8 is a
partially enlarged view illustrating a first belt region 11d , a
second belt region 11e and a peripheral portion 11a of the wig base
11 shown in FIG. 6. The first belt portion 11d comprises an inner
portion 11f with the hair attached thereon to be blended with the
hair attached to the top portion 11c, and an outer portion 11g with
the hair attached thereon to be blended with the hair attached to
the second belt portion 11e. The width L.sub.31 of the inner
portion 11f is required to be 1 cm, whereas the width L.sub.32 of
the outer portion 11g may be 0.5 cm. The first belt portion 11d
constitutes a part of a buffer region for solving the problem
caused by the difference in the curl diameters and/or the lengths
of the hairs attached to the top portion 11c and to the peripheral
portion 11a. Therefore, if the width L.sub.31 of the inner portion
11f is shorter than 1 cm, then since the region where the hair is
attached to blend with the hair attached to the top portion 11c is
small, a notch is caused in the hairs attached to the wig base 11.
On the other hand, since the outer portion 11g has small
differences in the curl diameters and/or the lengths of the hairs
attached to said outer portion 11g and to the second belt portion
11e, the neighboring hairs can be well blended if the outer portion
11g has a substantially half width as the inner portion 11f. From
the above, the width L.sub.3 of the first belt portion 11d needs to
be 1.5 cm. Conversely, if the width L.sub.3 of the first belt
portion 11d is longer than 2 cm, the region of the top portion 11c
is narrow, and hence it is not preferable because hair styles can
not be made freely. Also, if the width L.sub.3 of the first belt
portion 11d is wide, there will be caused a portion where the hairs
attached to the top portion 11c and to the second belt portion 11e
are not blended well near the border of the inner portion 11f and
the outer portion 11g, and as a result, the hair attached to the
first belt portion 11d is separated, and, not preferably, wig
wearing is visible from outside.
[0100] Explanation is made of the width L.sub.4 on the left and
right symmetrical line of the second belt portion 11e. The second
belt portion 11e comprises an inner portion 11h with the hair
attached thereon to be blended with the hair attached to the first
belt portion 11d, and an outer portion 11i with the hair attached
thereon to be blended with the hair attached to the peripheral
portion 11a. The width L.sub.42 of the outer portion 11i is
required to be 1 cm, whereas the width L.sub.41 of the inner
portion 11h may be 0.5 cm. The second belt portion 11e constitutes
another part of a buffer region of the bending rigidities of the
hairs attached to the top portion 11c and to the peripheral portion
11a. Therefore, if the width L.sub.42 of the outer portion 11i is
shorter than 1 cm, then since the region where the hair is attached
to blend with the hair attached to the peripheral portion 11a is
small, a notch is caused between the hair attached to the wig base
11. On the other hand, since the inner portion 11h has both small
differences in the curl diameters and/or the lengths of the hairs
attached to said inner portion 11h and to the first belt portion
11d and in bending rigidities, the neighboring hairs can be well
blended if it has a substantially half width as the outer portion
11i. From the above, the width L.sub.4 of the second belt portion
11e needs to be 1.5 cm. Conversely, if the width L.sub.4 of the
second belt portion 11e is longer than 2 cm, the region of the top
portion 11c is narrow, and hence it is not preferable because hair
styles can not be made freely. Also, if the width L.sub.4 of the
second belt portion 11e is wide, there will be caused a portion
where the hairs attached to the first belt portion 11d and to the
peripheral portion 11a are not blended well near the border of the
inner portion 11h and the outer portion 11i, and as a result, the
hair attached to the second belt portion 11e is separated, and, not
preferably, wig wearing is visible from outside.
[0101] Explanation is made of the width L.sub.5 on the left and
right symmetrical line of the peripheral portion 11a. The
peripheral portion 11a comprises an inner portion 11j with the hair
attached thereon to be blended with the hair attached to the second
belt portion 11e, and an outer portion 11k with the hair attached
thereon to be blended with the wearer's remaining hair. Since both
the curl diameters and/or the lengths and bending rigidities of the
hairs attached to said peripheral portion 11a and to the second
belt portion 11e in its inside are different, The width L.sub.51 of
the inner portion 11j is required to be 1 cm, whereas the outer
portion 11k is required to be 1 cm, because the hair for well
blending with the wearer's own hair remaining in said outer portion
11k is attached thereto. Therefore, the width L.sub.5 of the
peripheral portion 11a is required to be 2 cm. If the width L.sub.5
of the peripheral portion 11a is shorter than 2 cm, then the
wearer's own hair and the hairs attached to the peripheral portion
11a and to the second belt portion 11e are not well blended and
separated, so that it is not preferable because the periphery of
the wig base on the wearer's head is visible from outside.
Conversely, if the width L.sub.5 of the peripheral portion 11a is
longer than 2 cm, the region of the top portion 11c is narrow, and
hence it is not preferable because the wearer's preferred hair
styles can not be made. If the width L.sub.5 of the peripheral
portion 11a is wide, there will be caused a portion where the hairs
attached to the second belt portion 11e and the wearer's own hair
are not blended well near the border of the inner portion 11j and
the outer portion 11k, and as a result, the hair attached to the
peripheral portion 11a is separated, and, not preferably, wig
wearing is visible from outside.
[0102] The size design mentioned above is applicable when the wig
base 11 has a size larger than a certain level, but when the
wearer's head is small, that is, the wig base 11 has a size smaller
than a certain level, if the size design mentioned above is
applied, the size of the top portion 11c is smaller than the other
regions of the wig base 11. This is contrary to the search result
that the top portion 11c is the largest of the wearer's wig wearing
regions, and if the top portion 11c is too narrow, then the whole
balance of the wig is bad, and natural hair style can not be
attained. Therefore, when each width of the front to the back and
the left and right of the top portion 11c is smaller than 5 cm, the
width L.sub.1 from the front to the back of the forehead portion
11b, or the width from the front to the back on the left and right
symmetrical line from the first belt portion 11d to the peripheral
portion 11a, the size design is conducted as follows.
[0103] When the wig base 11 has a size smaller than a certain
level, the width L.sub.1 from the front to the back of the forehead
portion 11b of the wig base 11 is made L/3 for the width L from the
front to the back from the forehead portion 11b to the peripheral
portion 11a of the wig base 11, and the widths
L.sub.3+L.sub.4+L.sub.5 from the front to the back on the left and
right symmetrical line from the first belt portion 11d to the
peripheral portion 11a is made L/3. The width L.sub.3 from the
front to the back on the left and right symmetrical line of the
first belt portion 11d, the width L.sub.4 from the front to the
back on the left and right symmetrical line of the second belt
portion 11e, and the width L.sub.5 from the front to the back on
the left and right symmetrical line of the peripheral portion 11a
are arranged so that their ratio becomes 1.5:1.5:2.
[0104] As described above, in case that each width of the front to
the back and the left and right of the wig base 11 is 15 cm or
longer, the size design of each region of the wig base 11 is such
that the widths on the left and right symmetrical line of the
forehead portion 11b, the first belt portion 11d, the second belt
portion 11e, and the peripheral portion 11a are made 5 cm, 1.5 cm,
1.5 cm, and 2 cm, respectively, and the rest is allocated as the
region of the top portion 11c, whereas each width of the front to
the back and the left and right of the wig base 11 is shorter than
15 cm, the wig base 11 is partitioned to three equally, each of the
widths on the left and right symmetrical line of the forehead
portion 11b and the top portion 11c is made L/3 of the width L from
the front to the back of the wig base 11, and the rests are
allocated to the first belt portion 11d, the second belt portion
11e, and the peripheral portion 11a, and arranged so that each
width has the ratio 1.5:1.5:2.
[0105] The hair attached to the wig base 11 partitioned to a
plurality of regions has bending rigidity pre-determined for each
region. Since the hair 12 attached to the peripheral portion 11a of
the wig base 11 is arranged by blending with the wearer's own hair
in the surrounding region of the lost hair or the thin hair
portion, it has bending rigidity lower than natural hair.
[0106] On the other hand, the hair attached to the region from the
peripheral portion 11a toward the top portion in the wig base 11,
for example, the main region 11B of the forehead portion 11b, the
top portion 11c, and the first belt portion 11d, is designed as
having bending rigidity of the same level as natural hair. The hair
attached to the adjustment region 11C as the boundary region of the
peripheral portion 11a and the region 11B from the forehead toward
the top portion among the wig base 11 is designed to have
intermediate bending rigidity between the hairs attached to the
peripheral portion 11a and to the main region 11B.
[0107] Here, in order for said hair to have intermediate bending
rigidity, as described in detail later, the hair having bending
rigidity lower than natural hair and the hair having bending
rigidity of the same level as natural hair are mixed in the
pre-determined ratio of strands. Otherwise, a structure or a size
are adjusted so that the pre-determined value is attained between
bending rigidity of the hair attached to the peripheral region 11A
and bending rigidity of the hair attached to the main region
11B.
[0108] As described above, the hair attached to the region 11A of
the peripheral portion 11a in the wig base 11 has bending rigidity
lower than natural hair, preferably having bending rigidity of the
same level as the wearer's own hair 1, and more preferably the
farther from the wearer's own hair 1 on the head, the gradually
higher the bending rigidity of the attached hair, and the hair
attached to the main region 15B of the wig base 11 has bending
rigidity higher than the hair attached to the peripheral region
11A, and of the same level as natural hair. Thereby, the wearer's
own hair 1 growing on the scalp and the hair 12 attached to the
peripheral portion 11a of the wig base are well blended, stand up
and curve similarly to show similar behavior. On the other hand,
since the hair attached to the main region 11B of the wig base has
bending rigidity higher than the wearer's own hair 1, unique hair
styles can be formed which wearers could not expect to have,
depending upon hardness or bending strength of said hair.
[0109] The wig described above is such that the wig base is
partitioned to a plurality of regions, and the hairs of bending
rigidities corresponding to respective regions are attached to said
regions, and in each region of the wig base 11 shown in FIG. 6, the
hair length is adjusted, curled or not, the curl curvature when
curled is adjusted, or color is adjusted so that the artificial
hair formed at will can be used. By attaching said various
artificial hair to each region of the wig base 11 depending upon
the state of distribution or the color of the wearer's remaining
hair, hair styles can be formed responding to the wearer's
needs.
[0110] The hair attached to respective regions of the wig base 11
shown in FIG. 7, that is, to the peripheral region 11A, the main
region 11B, and the adjustment region 11C, not only has the
pre-determined bending rigidity, but also preferably has the
pre-determined curl diameter and/or length for each of the
peripheral portion 11a, the forehead portion 11b, the top portion
11c, the first belt portion 11d, and the second belt portion 11e.
That is, for a front hiding type wig, the hair 12 attached to the
peripheral portion 11a of the wig base 11 preferably not only has
bending rigidity equal to the wearer's own hair near the peripheral
portion of the wig, but also has equal curl diameter or length. In
case that the hair 13 attached to the top portion 11c of the wig
base 11 and the hair 12 attached to the peripheral portion 11a have
different curl diameters or lengths, a notch is not caused in the
hair attached to the wig base 11 by gradually changing the curl
diameter and/or length, and hence wig wearing is not visible. Also,
in case that bending rigidity of the hair 13 attached to the main
region 11B from the forehead portion 11b toward the top portion 11c
in the wig base 11 and bending rigidity of the hair 12 attached to
the region 11A of the peripheral portion 11a are different, the
hair is attached which has intermediate bending rigidity to the
adjustment region 11C, and hence wig wearing is hardly visible.
[0111] Explanation is next made of the case of a top wearing type
wig shown in FIG. 5. FIG. 9 is a plan view schematically
illustrating the wig base 31 of a top wearing type. An arrow mark
in the figure indicates the wearer's forward direction. Said wig
base 31 is partitioned to a plurality of regions by virtual lines.
The wig base 31 is constituted substantially left and right
symmetrically fitting to the wearer's head shape and size, and in
order for the attached hair to have different curl diameters and/or
lengths for respective regions, as shown in FIG. 9, it is
partitioned to five regions. That is, the wig base 31 is virtually
partitioned to the top portion 31e as its center region, the
forehead portion 31a neighboring said top portion 31e on the front
side, the left head portion 31b neighboring said top portion 31e on
the left side, the right head portion 31c neighboring said top
portion 31e on the right side, and the rear head portion 31d
neighboring said top portion 31e on the rear side. Since said top
wearing type wig base 31 is such that the wig wearing region is
only the wearer's top, unlike the front hiding type wig base 11
shown in FIG. 6, it is not formed to partially cover a shaved
portion or a forehead to be present on the wearer. The wig base 31
is also otherwise virtually partitioned to three to change bending
rigidity of the attached hair in each region, namely, the total
peripheral region 31A formed along the outer periphery of a
forehead portion 31a, left and right side head portions 31b and
31c, and a rear head portion 31d, the main region 31B corresponding
to a head top zoning the center region of the wig base 31, and the
circular adjustment region 31C between the total peripheral region
31A and the main region 31B. Here, the main region 31e corresponds
to the top portion 31e among the five-partitioned regions, and the
total peripheral region 31A is the region neighboring the inner
periphery of the wearer's wig wearing region.
[0112] Explanation is made below of optimal sizes of respective
regions of the wig base 31. Here, the length along the curved
surface of the wig base 31 between the front end of the forehead
portion 31a and the rear end of the rear head portion 31d of the
wig base 31 is defined as L, and the length along the curved
surface of the wig base 31 between both ends of the left and the
right side head portions 31b and 31c of the wig 31 is defined as
D.
[0113] The widths L.sub.6 and L.sub.7 of the front and the rear
head portions 31a and 31d of the wig base 31 are made to have the
length each 1/4 of the length from the front to the back L of the
wig base 31. The lengths D.sub.6 and D.sub.7 of the left and right
side head portions 31b and 31c are made each 1/4 of the left and
right length D. Thereby, in the center region of the wig base 31,
the top portion 31e of the wig base 31 is zoned to have length from
the front to the back 1/2 of the length from the front to the back
L of the wig base 31, and 1/2 of the left and right length D of the
wig base 31. Further, an adjustment region 31C is zoned with the
borders at the positions which equally partition the respective
regions of the forehead portion 31a, the left and right side head
portions 31b and 31c, and the rear head portion 31d, in order to
prevent the hair attached between the total peripheral region 31A
and the main region 31B of the wig base 31 to separate for wig
wearing to be visible. Said borders are provided along the whole
outer periphery of the wig base at the intermediate position with
the border between the outer periphery of the wig base 31 and the
top portion 31e.
[0114] FIG. 10 is a schematic view for explanation of optimal size
design of each region of a wig base 31. It is similar to the case
of FIG. 9 to define the length as L in the direction from the front
to the back along the wig base 31 from the front end of the
forehead portion 31a to the rear end of the rear head portion 31d
of the wig base 31, and the length as D in the left and right
direction along the wig base 31 between the left end of the left
side head portion 31b and the right end of the right side head
portion 31c. The lengths and the divisions made by equally dividing
the length L from the front to the back to four are defined
sequentially as L.sub.11 to L.sub.14 from the forehead portion
side, the lengths and the divisions made by equally dividing the
left and right length D to four are defined sequentially as
D.sub.11 to D.sub.14 from the left side head portion side, and the
virtual lines equally dividing to four longitudinally and
horizontally are shown in the figure.
[0115] Since the top portion 31e is an important region to affect
the wearer's appearance and hair style, it is required to occupy
the center of the wig as widely as possible. Therefore, the top
portion 31e is zoned, as shown in FIG. 10, by the border line 35a
with the forehead portion 31a, the border line 35b with the left
side head portion 31b, the border line 35c with the right side head
portion 31c, and by the border line 35d with the rear head portion
31d. The top portion 31e is zoned at the center region of the wig
base 31 so that the border line 35b with the left side head portion
31b and the border line 35c with the right side head portion 31c
are the division of the length L.sub.12+L.sub.13, and the border
line 35a with the forehead portion 31a and the border line 35d with
the rear head portion 31d are the division of the length
D.sub.12+D.sub.13. That is, the region of the top portion 31e is
zoned with the length 1/2 as the length L from the front to the
back and as the left and right length D, respectively, of the wig
base 31.
[0116] The forehead portion 31a is zoned by the border line 35a
with the top portion 31e and by the border lines 35e and 35f with
the left and right side head portions 31b and 31c. Its size is so
designed that the left and right length on the border line 35a with
the top portion 31e is D.sub.12+D.sub.13, and the length from the
border line 35a with the top portion 31e to the front edge of the
wig base 31 is L.sub.11 of the ratio 1/4 of the length L from the
front to the back of the wig base 31. The border lines 35e and 35f
with the left and right side head portions 31b and 31c of the
forehead portion 31a are extended respectively diagonally to the
left and right from both ends of the border line 35a with the top
portion 31e, that is, in the direction of the arrow mark in the
figure rotated substantially 45 degrees to the left and right. With
the border lines 35e and 35f extending respectively diagonally to
the left and right, undesirable hair parting can not be generated
in the hair attached respectively to the forehead portion 31a and
to the left and right side head portions 31b and 31c. Therefore,
wig wearing is prevented from exposure.
[0117] The left side head portion 31b is zoned by the border line
35e with the forehead portion 31a, the border line 35b with the top
portion 31e, and by the border line 35g with the rear head portion
31d. Its size is so designed that the length from the front to the
back on the border line 35b with the top portion 31e is
L.sub.12+L.sub.13, and the length from the border line 35b with the
top portion 31e to the left edge of the wig base 31 is D.sub.11 of
the ratio 1/4 of the left and right length D of the wig base 31.
Here, the border line 35e with the forehead portion 31a is extended
diagonally to the left from the front end of the border line 35b
with the top portion 31e, whereas the border line 35g with the rear
head portion 31d is extended on the left end of the border line 35d
between the top portion 31e and the rear head portion 31d along
said border line 35d.
[0118] The right side head portion 31c is zoned by the border line
35f with the forehead portion 31a, the border line 35c with the top
portion 31e, and by the border line 35h with the rear head portion
31d. Its size is so designed that the length from the front to the
back on the border line 35c with the top portion 31e is
L.sub.12+L.sub.13, and the length from the border line 35c with the
top portion 31e to the right edge of the wig base 31 is D.sub.14 of
the ratio 1/4 of the left and right length D of the wig base 31.
Here, the border line 35f with the forehead portion 31a is extended
diagonally to the right from the front end of the border line 35c
with the top portion 31e, whereas the border line 35h with the rear
head portion 31d is extended on the right side of the border line
35d between the top portion 31e and the rear head portion 31d along
said border line 35d.
[0119] The rear head portion 31d is zoned by the border line 35d
with the top portion 31e and by the border lines 35g and 35h with
the left and right side head portions 31b and 31c. The left and
right length on the border line 35d with the top portion 31e is
D.sub.12+D.sub.13, but is extended to the outer periphery of the
left and right side head portions 31b and 31c. Also, the size is so
designed that the length from the border line 35d with the top
portion 31e to the rear edge of the wig base 31 is L.sub.14 of the
ratio 1/4 of the length L from the front to the back of the wig
base 31. Here, the border lines 35g and 35h with the left and right
side head portions 31b and 31c of the rear head portion 31d are
extended respectively to the left and right from the border line
35d between the top portion 31e and the rear head portion 31d.
Therefore, the hair attached to the rear head portion 31d lies down
on the scalp together with the wearer's own hair, resulting in well
blending of the hair and the wearer's own hair. Therefore, since
hair is not parted improperly, wig wearing is prevented from
exposure.
[0120] As explained above, since the top portion 31e is an
important region to affect the wearer's appearance and hair style,
it is required to occupy as widely as possible, and hence is
constituted to have sizes of the ratio 1/2 of the longitudinal L
and 1/2 of the horizontal D. On the other hand, the portions where
the hair selected by consideration of the curl diameter and the
length of the wearer's own hair is attached, such as the forehead
portion 31a, the left and right side head portions 31b and 31c, and
the rear head portion 31d, are preferably distributed and arranged
with good balance, so as to have the sizes of the ratio
substantially 1/4 of longitudinal L and 1/4 of horizontal D in the
outward direction from the border lines 35a to 35d with the
forehead portion 31a, the left and right side head portions 31b and
31c, and with the rear head portion 31d. Thereby, the top portion
33e as an important region to affect the wearer's appearance and
hair style can be reserved as widely as possible, and moreover, to
each region of the forehead portion 31a, the left and right side
head portions 31b, 31c, and the rear head portion 31d where hair is
attached suitably to the curl diameter and the length of the
wearer's own hair, the hair can be attached as much as well
blendable with the wearer's own hair. Consequently, the wearer's
preferred hair style can be formed, and wig wearing is not visible
due to well blending of the hair attached to the wig with the
wearer's own hair.
[0121] A Comparative Example is next explained which has a
partition ratio different from FIG. 10.
[0122] FIG. 11 is a view illustrating a first Comparative Example
with respect to the regional partition of a wig base. In the
figure, L, D, and an arrow mark are the same as in the case of FIG.
10. The wig base 32 shown in FIG. 11 is common with respect to the
aspects that it is partitioned to five regions, the forehead
portion 32a, the left and right side head portions 32b, 32c, the
rear head portion 32d, the top portion 32e as in FIG. 10, but is
different from FIG. 10 with respect to the aspects that the length
and the division from three equal division of the length L from the
front to the back of the wig base 32 are defined sequentially as
L.sub.15 to L.sub.17 from the forehead portion side, and the length
and the division from three equal division of the left and right
length D are defined sequentially as D.sub.15 to D.sub.17 from the
left side head portion side and the virtual lines dividing equally
to three longitudinally and horizontally are shown in the figure.
Namely, the top portion 32e is zoned in the center region of the
wig base 32 so that the border line 36b with the left side head
portion 32b and the border line 36c with the right side head
portion 36c are the divisions of the length L.sub.16, and the
border line 36a with the forehead portion 32a and the border line
36d with the rear head portion 32d are the divisions of the length
D.sub.16. That is, the region of the top portion 32e is zoned with
the lengths of 1/3 of the length L from the front to the back and
the left and right length D of the wig base 32.
[0123] The left side head portion 32b is the same as in FIG. 10
with respect to the aspects that it is zoned by the border line 36e
with the forehead portion 32a, the border line 36b with the top
portion 32e, and by the border line 36g with the rear head portion
32d, but is different from the case of FIG. 10 with respect to the
aspects that the size is so designed that the length from the front
to the back on the border line 36b with the top portion 32e is
L.sub.16, and the length from the border line 36b with the top
portion 32e to the left edge of the wig base 32 is D.sub.15 of the
ratio 1/3 of the left and right length D of the wig base 32. The
right side head portion 32c is the same as the case of FIG. 10 with
respect to the aspects that it is zoned by the border line 36f with
the forehead portion 32a, the border line 36c with the top portion
32e, and by the border line 36h with the rear head portion 32d, but
is different with respect to the aspects that the size is so
designed that the length from the front to the back on the border
line 36c with the top portion 32e is L.sub.16, and the length from
the border line 36c with the top portion 32e to the right edge of
the wig base 32 is D.sub.17 of the ratio 1/3 of the left and right
length D of the wig base 32. In the left and right side head
portions 32b and 32c, it is the same as in FIG. 10 that the border
lines 36e and 36f with the forehead portion 32a are extended from
the front end of the border line 36c with the top portion 32e in
the left and right diagonal direction, and the border lines 36g and
36h with the rear head portion 32d are extended left and right on
the border line 35d between the top portion 32e and the rear head
portion 32d.
[0124] In the regional partition shown in FIG. 11, since sizes are
designed with the top portion 32e of the ratio 1/3 of the length L
from the front to the back and the ratio 1/3 of the left and right
length D, first of all, it is not preferable that the top portion
32e as an important region to affect the wearer's appearance and
hair style can not be reserved widely, and hence the wearer's
desired hair style can not be formed. Secondly, compared with the
top portion 32e, each region of the forehead portion 32a, the left
and right side head portions 32b, 32c, and the rear head portion
32d has a wide area, and it is not preferable that the hair
attached to the whole wig base 32 are unbalanced, and hence wig
wearing is visible.
[0125] FIG. 12 is a view illustrating a second Comparative Example
with respect to the regional partition of a wig base. In the
figure, L, D, and an arrow mark are the same as in the case of FIG.
10. The wig base 33 shown in FIG. 12 is common with respect to the
aspects that it is partitioned to five regions, the forehead
portion 33a, the left and right side head portions 33b, 33c, the
rear head portion 33d, the top portion 33e as in FIG. 10, but is
different from FIG. 10 with respect to the aspects that the length
and the division from five equal division of the length L from the
front to the back of the wig base 33 are defined sequentially as
L.sub.18 to L.sub.22 from the forehead portion side, the length and
the division from five equal division of the left and right length
D are defined sequentially as D.sub.18 to D.sub.22 from the left
side head portion side, and the virtual lines dividing equally to
five longitudinally and horizontally are shown in the figure.
Namely, the top portion 33e is zoned in the center region of the
wig base 33 so that the border line 37b with the left side head
portion 33b and the border line 37c with the right side head
portion 33c are the divisions of the length
L.sub.19+L.sub.20+L.sub.21, and the border line 37a with the
forehead portion 33a and the border line 37d with the rear head
portion 33d are the divisions of the length
D.sub.19+D.sub.20+D.sub.21. That is, the region of the top portion
33e is zoned with the lengths of 3/5 of the length L from the front
to the back and the left and right length D of the wig base 33,
respectively.
[0126] The left side head portion 33b is the same as in the case of
FIG. 10 with respect to the aspects that it is zoned by the border
line 37e with the forehead portion 33a, the border line 37b with
the top portion 33e, and by the border line 37g with the rear head
portion 33d, but is different from the case of FIG. 10 with respect
to the aspects that the size is so designed that the length from
the front to the back on the border line 37b with the top portion
33e is L.sub.19+L.sub.20+L.sub.21, and the length from the border
line 37b with the top portion 33e to the left edge of the wig base
33 is D.sub.18 of the ratio 1/5 of the left and right length D of
the wig base 33. The right side head portion 33c is the same as in
the case of FIG. 10 with respect to the aspects that it is zoned by
the border line 37f with the forehead portion 33a, the border line
37c with the top portion 33e, and by the border line 37h with the
rear head portion 33d, but is different with respect to the aspects
that the size is so designed that the length from the front to the
back on the border line 37c with the top portion 33e is
L.sub.19+L.sub.20+L.sub.21, and the length from the border line 37c
with the top portion 33e to the right edge of the wig base 33 is
D.sub.22 of the ratio 1/5 of the left and right length D of the wig
base 33. In the left and right side head portions 33b and 33c, it
is the same as in FIG. 10 that the border lines 37e and 37f with
the forehead portion 33a are extended from the front end of the
border line 37c with the top portion 33e in the left and right
diagonal direction, and the border lines 37g and 37h with the rear
head portion 33d are extended left and right on the border line 37d
between the top portion 33e and the rear head portion 33d.
[0127] In the regional partition shown in FIG. 12, since sizes are
designed with the top portion 33e of the ratio 3/5 of the length L
from the front to the back and the ratio 3/5 of the left and right
length D, the top portion 33e as an important region to affect the
wearer's appearance and hair style can be reserved widely. However,
since each region is made narrow for the forehead portion 33a, the
left and right side head portions 33b, 33c, and the rear head
portion 33d where the hair suited to the curl diameter and the
length of the wearer's own hair is attached, it is not preferable
that the attached hair and the wearer's own hair are not well
blended.
[0128] The hair attached to the wig base 31 of a top wearing type
shown in FIG. 5 has, as shown in FIG. 9, bending rigidity
pre-determined for each of the total peripheral region 31A, the
main region 31B, and the adjustment region 31C between them. Since
the hair 32 attached to the total peripheral region 31A of the wig
base 31 is blended and arranged with the wearer's own hair in the
surrounding region of the wearer's lost hair or the thin hair
portions, it has bending rigidity lower than natural hair. On the
other hand, the hair attached to the region 31B of the top portion
31e in the wig base 31 has bending rigidity of the same level as
natural hair, and the hair attached to the adjustment region 31C
between the total peripheral region 31A and the region 31B of the
top portion 31e of the wig base 31 has intermediate bending
rigidity between the hair attached to the total peripheral region
31A and the hair attached to the region 31B of the top portion 31e.
Here, in order for said hair to have intermediate bending rigidity,
as described later, the hair having bending rigidity lower than
natural hair and the hair having bending rigidity of the same level
as natural hair are mixed in the pre-determined ratio of strands.
Otherwise, a structure or a size are adjusted so that the
pre-determined value is attained between bending rigidity of the
hair attached to the total peripheral region 31A and bending
rigidity of the hair attached to the region 31B of the top portion
31e. Thereby, in a top wearing type wig, like a front hiding type
wig, the wearer's own hair near the lost hair portion and the hair
attached to the total peripheral region 31A of the wig base 31
blend well, so well blended that a notch is not caused between the
hairs attached to the wig base, and hence wig wearing is hardly
visible.
[0129] The hair to be attached to each region of the wig base 31
has preferably not only the pre-determined bending rigidity but
also a curl diameter and a length pre-determined for each region.
That is, in a top wearing type wig, the hair 32 attached to the
total peripheral region 31A not only has bending rigidity
equivalent to the wearer's own hair near the wig wearing region,
but also the curl diameter and the length are preferably equivalent
between them. If the hair 33 attached to the region 31B of the top
portion 31e and the hair 32 attached to the total peripheral region
31A have different curl diameters and lengths, then a notch is not
caused by the hair attached to the wig base 31 and wig wearing is
not visible by gradually changing the curl diameter and/or the
length. It is possible to curl the hair attached to the wig base 31
and to adjust its length before the wig is worn, or upon wearing
the wig, but it is not preferable because the working process
becomes complicated.
[0130] Here, compared with a wig with hair having not different
lengths and curl diameters on each region of a wig base, the wig of
this Comparative Example has an equal length and curl diameter for
each strand, and hence the hair is too uniform as a whole, so that
it is not preferable that a free hair style can not be formed. If
such a wig with the too uniform hair is worn, cutting the hair
attached to the wig base is necessary for hair style adjustment.
Conversely, compared with a wig with the hair attached to the wig
base of randomly different lengths and curl diameters, the wig of
this Comparative Example has a degree of freedom in hair styles
themselves, but it is not preferable that the hairs are too random,
and a hair style lacks uniformity. On the other hand, a free hair
style can be formed by attaching the hairs of the pre-determined
lengths and the curl diameters for respective regions of the wig
base like the wig of the present invention.
[0131] Explanation is next made of the hair attached to the wig
bases 11 and 31. The hairs attached to the wig bases 11 and 31 can
be formed to have different bending rigidities for the respective
partitioned regions of the wig bases 11 and 31. As the hair, an
artificial hair made of, for example, a polyamide fiber with a
sheath/core structure can be used.
[0132] Such an artificial hair made of a polyamide fiber with a
sheath/core structure, utilizing the property of the polyamide
fiber, has a core portion of a polyamide fiber of high bending
rigidity, and a sheath portion of a polyamide fiber of bending
rigidity lower than the core portion, and the bending rigidity of
the whole artificial hair can be controlled by adjusting the mass
ratio of the sheath and the core portions. As the polyamide resin
as the material for the core portion, a semi-aromatic polyamide
resin of high strength and rigidity, for example, a polymer of an
alternative copolymer of hexamethylene diamine and terephthalic
acid expressed by Chemical Formula 1, for example, nylon 6T, or a
polymer in which adipic acid and metaxylylene diamine alternatively
bonded by amide bonds as expressed by Chemical Formula 2, for
example, nylon MXD6, may be used. Here, the artificial hair using a
polymer material expressed by Chemical Formula 2 as the core
portion material is more preferable than the artificial hair using
a polymer material expressed by Chemical Formula 1 as the core
portion material in that hair setting is easier.
##STR00001##
[0133] As the polyamide resin as the material for the sheath
portion, a polyamide resin of bending rigidity lower than the core
portion material, for example as a linear aliphatic polyamide, a
polymer of a ring opening polymer of caprolactam expressed by
Chemical Formula 3, for example, nylon 6, or a polymer of an
alternative copolymer of hexamethylene diamine and adipic acid
expressed by Chemical Formula 4, for example, nylon 66 may be
used.
##STR00002##
[0134] Thus, by making a sheath/core structure of a polyamide
artificial hair using a polyamide of high bending rigidity for a
core portion and using a polyamide of bending rigidity lower than
the core portion for a sheath portion, and by adjusting the mass
ratio of the sheath and the core portions, a fiber of the desired
bending rigidity can be obtained.
[0135] The bending rigidity is a physical property applicable in
general to fibers and the like, and for hair, too, recently
recognized as a property relating to a sensuous property such as
feeling (appearance, tactile and texture feeling). As the
measurement of bending rigidity of a fiber, KAWABATA method of
measurement and its principle are widely known for textile, and its
improved version Single Hair Bending Tester (KATOTECH, LTD., Model
KES-FB2-SH) was used to measure bending rigidity of artificial
hair. As the method of measurement for any case of artificial and
natural hair, each one strand of 1 cm was bent at equal speed in an
arc shape to a certain curvature, the small bend moment
accompanying it was detected, and the relationship of the bend
moment and the curvature was measured. Bending rigidity was
obtained therefrom by bend moment/curvature change. Typical
measurement conditions are shown below.
(Measurement Conditions)
[0136] Distance between Chucks: 1 cm
[0137] Torque Detector: Detection of Torque of Tortion Wire (Steel
Wire)
[0138] Torque Sensitivity: 1.0 gfcm (at Full Scale 10V)
[0139] Curvature: .+-.2.5 cm.sup.-1
[0140] Rate of Bend Deviation: 0.5 cm.sup.-1/sec
[0141] Measurement Cycle: 1 Round Trip.
Here, a chuck is a mechanism for clipping said each hair of 1
cm.
[0142] The artificial hair manufactured by the conditions that the
sheath is made of nylon 6 or nylon 66, the core of nylon 6T or
nylon MXD6, the discharge volume ratio of the sheath/core
components upon melt spinning is close to 1/2 (the sheath/core mass
ratio 32/68) has bending rigidity close to the minimum value of
that of natural hair (about 6.5.times.10.sup.-3
gfcm.sup.2/strand).
[0143] The artificial hair manufactured by the discharge volume
ratio of the sheath/core components upon melt spinning 1/7 (the
sheath/core mass ratio 12/88) has bending rigidity close to the
maximum value of that of natural hair (about 7.8.times.10.sup.-3
gfcm.sup.2/strand).
[0144] Here, natural hair means the ordinary hair growing on a
human's scalp, and has a big personal deviation in bending
rigidities. Therefore, head hairs were collected from 25 males and
38 females of age classes between 20 to 50 years old, and their
bending rigidities were measured for the samples of 80 .mu.m
diameter under the same circumstance, namely, under the
circumstance of temperature 22.degree. C. and humidity 40%. The
bending rigidities shown below are the values under the
circumstance of temperature 22.degree. C. and humidity 40%.
[0145] Explanation is next made of the pattern to attach artificial
hair having such pre-determined bending rigidity to a wig base.
[0146] At the beginning, explanation is made of the case of a front
hiding type wig. FIG. 13 is a table showing the properties of the
hair attached to a wig base 11 in a first to a fourth embodiments
of attaching patterns.
[0147] Explanation is made of a first embodiment of the pattern to
attach hair to a wig base 11. Said first embodiment is suitable to
an ordinary wearer. The hair for a wig is made of a polyamide fiber
of a sheath/core structure. The artificial hair having bending
rigidity 3.9.times.10.sup.-3 gfcm.sup.2/strand which is about 40%
lower than the minimum value of that of natural hair (about
6.5.times.10.sup.-3 gfcm.sup.2/strand) is attached to a peripheral
portion 11a of a wig base 11. In a second belt portion 11e inside
it are attached artificial hair having bending rigidity
3.9.times.10.sup.-3 gfcm.sup.2/strand and artificial hair having
bending rigidity 6.5.times.10.sup.-3 gfcm.sup.2/strand uniformly
distributed so that the mass ratio becomes half to half. Artificial
hair having 6.5.times.10.sup.-3 gfcm.sup.2/strand is attached to
the first belt portion 11d, the top portion 11c, and the forehead
portion 11b inside it. Here, bending rigidities of natural hair
have a big personal deviation, and the hair growing on the wearer's
scalp has low bending rigidity in general. The wig of the first
embodiment is assumed as the case wherein the bending rigidity of
the wearer's own hair is about 3.4 to 4.4.times.10.sup.-3
gfcm.sup.2/strand. In this connection, if the bending rigidity of
the hair attached to at least a peripheral portion of a wig is
about .+-.0.5 to 0.8.times.10.sup.-3 gfcm.sup.2/strand to the
bending rigidity of the wearer's own hair, then it is within the
allowable range. Thus, if artificial hair having bending rigidity
lower than that of ordinary natural hair is attached to the
peripheral portion 11a of the wig base 11, then the attached
artificial hair tends to blend well with the wearer's own hair.
[0148] Thus, while the hair attached to the peripheral portion 11a
of the wig base 11 has bending rigidity lower than that of natural
hair, that is, bending rigidity of the same level as that of the
wearer's own hair, the hair attached to the top portion 11c and the
forehead portion 11b where the hair is not likely to be mixed with
the wearer's own hair has high bending rigidity compared with the
hair attached to the peripheral portion 11a. Therefore, since the
hair attached to the peripheral portion 11a of the wig base 11 is
easily blended well with the remaining hair growing on the wearer's
scalp, and shows similar behavior to the wearer's own hair by the
influence of such circumstances as humidity, it is not likely for
wig wearing to be recognized. In addition, since the hair attached
to the forehead portion 11b, the top portion 11c, and the first
belt portion 11d has higher bending rigidity than the wearer's
remaining hair, various hair styles can be made in response to the
wearer's needs.
[0149] Explanation is made of a second embodiment of the pattern to
attach hair to a wig base 11. Its difference from the first
embodiment is that the hair attached to the forehead portion 11b,
the top portion 11c, and the first belt portion 11d of the wig base
11 and the hair attached to the second belt portion 11e mixed
therein uniformly have low bending rigidities. It is the same case
as in the first embodiment that the hair attached to the wig base
is made of a polyamide fiber of a sheath/core structure.
[0150] Artificial hair having bending rigidity 3.9.times.10.sup.-3
gfcm.sup.2/strand is attached to the peripheral portion 11a of the
wig base 11. In a second belt portion 11e inside it are attached
artificial hair having bending rigidity 3.9.times.10.sup.-3
gfcm.sup.2/strand and artificial hair having bending rigidity
5.2.times.10.sup.-3 gfcm.sup.2/strand uniformly distributed so that
the mass ratio becomes half to half. Artificial hair having bending
rigidity 5.2.times.10.sup.-3 gfcm.sup.2/strand is attached to the
first belt portion 11d inside, the top portion 11c, and the
forehead portion 11b.
[0151] The second embodiment differs from the first in that bending
rigidity of the hair attached to the forehead portion 11b, the top
portion 11c, and the first belt portion 11d is low compared with
the first embodiment, and the whole hair attached to the wig is so
designed as to have lower bending rigidity than natural hair, so
that it is suitable to the wearer having comparatively soft hair,
that is, suitable to the user having hair of bending rigidity about
3.1 to 4.7.times.10.sup.-3 gfcm.sup.2/strand.
[0152] Explanation is made of a third embodiment of the pattern to
attach hair to a wig base 11. Its difference from the first
embodiment is that, contrary to the second embodiment, the hair
attached to the forehead portion 11b, the top portion 11c, and the
first belt portion 11d of the wig base 11 and the hair attached to
the second belt portion 11e mixed therein have strengthened
rigidities. It is the same case as in the first embodiment that the
hair attached to the wig base 11 is made of a polyamide fiber of a
sheath/core structure.
[0153] Artificial hair having bending rigidity 3.9.times.10.sup.-3
gfcm.sup.2/strand is attached to the peripheral portion 11a of the
wig base 11. In a second belt portion 11e inside it are attached
artificial hair having bending rigidity 3.9.times.10.sup.-3
gfcm.sup.2/strand and artificial hair having bending rigidity
7.8.times.10.sup.-3 gfcm.sup.2/strand uniformly distributed so that
the mass ratio becomes half to half. Artificial hair having bending
rigidity 7.8.times.10.sup.-3 gfcm.sup.2/strand is attached to the
first belt portion 11d inside, the top portion 11c, and the
forehead portion 11b.
[0154] Different from the first embodiment, bending rigidity of the
hair attached to the forehead portion 11b, the top portion 11c, and
the first belt portion 11d is high compared with the first
embodiment to increase the difference from natural hair, bulky and
rough feeling can be attained, thereby hair styles so far not
realized, for example, with standing hair can be formed. Therefore,
it is suitable to the wearers requiring hair styles of bulky
feeling. It is assumed for the case wherein the wearer's own hair
has bending rigidity about 3.4 to 4.4.times.10.sup.-3
gfcm.sup.2/strand.
[0155] Explanation is made of a fourth embodiment of the pattern to
attach hair to a wig base 11. The fourth embodiment differs from
the third in that bending rigidities of the hair attached to the
peripheral portion 11a of the wig base 11 and of the hair attached
to the second belt portion 11e mixed therein are more strengthened.
It is suitable to the case where the wearer's remaining hair has
bending rigidity of the same level as natural hair of a person who
does not need a wig. It is the same case as in the first embodiment
that the hair attached to the wig base 11 is made of a polyamide
fiber of a sheath/core structure.
[0156] Artificial hair having bending rigidity 5.2.times.10.sup.-3
gfcm.sup.2/strand is attached to the peripheral portion 11a of the
wig base 11. In a second belt portion 11e inside it are attached
artificial hair having bending rigidity 5.2.times.10.sup.-3
gfcm.sup.2/strand and artificial hair having bending rigidity
7.8.times.10.sup.-3 gfcm.sup.2/strand uniformly distributed so that
the mass ratio becomes half to half. Artificial hair having bending
rigidity 7.8.times.10.sup.-3 gfcm.sup.2/strand is attached to the
first belt portion 11d inside, the top portion 11c, and the
forehead portion 11b.
[0157] Different from the third embodiment, when the wearer's
remaining hair has rigidity of the same level as that of ordinary
natural hair, that is, if bending rigidity of the wearer's
remaining hair is about 5.0 to 6.5.times.10.sup.-3
gfcm.sup.2/strand, the extent of the wearer's remaining hair can be
responded by attaching artificial hair having bending rigidity of
the same level as that of the remaining hair. Since rigid
artificial hair is attached to the forehead portion 11b of the wig
base 11 and the top portion 11c, hair styles of bulky feeling can
be formed, and the hair disturbance can be prevented.
[0158] As was explained above, the artificial hair attached to the
wig base is made of a polyamide fiber having a sheath/core
structure in any of the first to the fourth embodiments, but, as
explained in the fifth to the eighth embodiments below, a first
artificial hair of a polyamide fiber having a sheath/core structure
and a second artificial hair of a polyester fiber may be uniformly
mixed properly in the pre-determined ratio, and attached to
partitioned regions of the wig base.
[0159] The second artificial hair of a polyester fiber has the
following structure. The second artificial hair of a polyester
fiber can change bending rigidity by adjusting the fiber diameter
of, for example, polyethylene terephthalate, or by adjusting the
mixing ratio of polybutylene terephthalate into polyethylene
terephthalate as the feed material to be melted upon spinning. The
artificial hair with polyethylene terephthalate as a main component
increases its bending rigidity linearly as its diameter increases.
For example, when the average diameter increases from 50 .mu.m to
70 .mu.m, its bending rigidity increases from 6.70.times.10.sup.-3
gfcm.sup.2/strand to 7.67.times.10.sup.-3 gfcm.sup.2/strand. On the
other hand, by mixing polybutylene terephthalate into polyethylene
terephthalate, and increasing its mixing ratio, bending rigidity
can be reduced. By dispersing and mixing said second polyester
artificial hair into the first polyamide artificial hair, bundling
tendency of the polyamide fiber artificial hair can be suppressed
resulting in feeling closer to natural hair.
[0160] Explanation is made of a fifth embodiment of the pattern to
attach hair to a wig base 11. FIG. 14 is a table showing the
properties of the hair attached to a wig base 11 in a fifth
embodiment of attaching patterns. Said fifth embodiment is a
modified example of the above-mentioned first embodiment. They are
different in that it uses the first artificial hair made of a
polyamide fiber of a sheath/core structure and the second
artificial hair made of a polyester fiber as the hair to be
attached to the wig base 11.
[0161] In the second belt portion 11e of the wig base 11 are the
first artificial hair having bending rigidity 3.9.times.10.sup.-3
gfcm.sup.2/strand and the first artificial hair having bending
rigidity 6.5.times.10.sup.-3 gfcm.sup.2/strand uniformly
distributed and mixed so that the mass ratio becomes half to half,
and further the second artificial hair having bending rigidity
6.5.times.10.sup.-3 gfcm.sup.2/strand is uniformly mixed and
attached. Here, the mixing ratio of the first and the second
artificial hair is 80:20 in mass ratio. In the first belt portion
11d, the top portion 11c, and the forehead portion 11b, the first
artificial hair having bending rigidity 6.5.times.10.sup.-3
gfcm.sup.2/strand and the second artificial hair having bending
rigidity 6.5.times.10.sup.-3 gfcm.sup.2/strand are uniformly mixed
and attached. Here, the mixing ratio of the first and the second
artificial hair is 80:20 in mass ratio. As described above, since
the second artificial hair made of a polyester fiber is mixed in
the first artificial hair made of a polyamide fiber and attached to
the forehead portion 11b, the top portion 11c, and the first belt
portion 11d, the bundling tendency of a polyamide fiber can be
suppressed, and hair styles of flow feeling can be formed.
[0162] Explanation is made of a sixth to an eighth embodiments of
the pattern to attach hair to a wig base 11. Said sixth to the
eighth embodiments are modified examples of the above-mentioned
second to the fourth embodiments. They are different in that it
uses the first artificial hair made of a polyamide fiber of a
sheath/core structure and the second artificial hair made of a
polyester fiber as the hair to be attached to the wig base 11.
[0163] FIG. 15 is a table showing the properties of the hair
attached to a wig base 11 in the sixth embodiment of attaching
patterns. In the sixth embodiment, in the second belt portion 11e
of the wig base 11 are the first artificial hair having bending
rigidity 3.9.times.10.sup.-3 gfcm.sup.2/strand and the first
artificial hair having bending rigidity 5.2.times.10.sup.-3
gfcm.sup.2/strand uniformly distributed and mixed so that the mass
ratio becomes half to half, and further the second artificial hair
having bending rigidity 6.5.times.10.sup.-3 gfcm.sup.2/strand is
uniformly mixed and attached. Here, the mixing ratio of the first
and the second artificial hair is 80:20 in mass ratio. In the first
belt portion 11d, the top portion 11c, and the forehead portion
11b, the first artificial hair having bending rigidity
5.2.times.10.sup.-3 gfcm.sup.2/strand and the second artificial
hair having bending rigidity 6.5.times.10.sup.-3 gfcm.sup.2/strand
are uniformly mixed and attached. Here, the mixing ratio of the
first and the second artificial hair is 80:20 in mass ratio.
[0164] FIG. 16 is a table showing the properties of the hair
attached to a wig base 11 in a seventh embodiment of attaching
patterns. In the seventh embodiment, in the second belt portion 11e
of the wig base 11 are the first artificial hair having bending
rigidity 3.9.times.10.sup.-3 gfcm.sup.2/strand and the first
artificial hair having bending rigidity 7.8.times.10.sup.-3
gfcm.sup.2/strand uniformly distributed and mixed so that the mass
ratio becomes half to half, and further the second artificial hair
having bending rigidity 6.5.times.10.sup.-3 gfcm.sup.2/strand is
uniformly mixed and attached. Here, the mixing ratio of the first
and the second artificial hair is 80:20 in mass ratio. In the first
belt portion 11d, the top portion 11c, and the forehead portion
11b, the first artificial hair having bending rigidity
7.8.times.10.sup.-3 gfcm.sup.2/strand and the second artificial
hair having bending rigidity 6.5.times.10.sup.-3 gfcm.sup.2/strand
are uniformly mixed and attached. Here, the mixing ratio of the
first and the second artificial hair is 80:20 in mass ratio.
[0165] FIG. 17 is a table showing the properties of the hair
attached to a wig base 11 in an eighth embodiment of attaching
patterns. In the eighth embodiment, in the second belt portion 11e
of the wig base 11 are the first artificial hair having bending
rigidity 5.2.times.10.sup.-3 gfcm.sup.2/strand and the first
artificial hair having bending rigidity 7.8.times.10.sup.-3
gfcm.sup.2/strand uniformly distributed and mixed so that the mass
ratio becomes half to half, and further the second artificial hair
having bending rigidity 6.5.times.10.sup.-3 gfcm.sup.2/strand is
uniformly mixed and attached. Here, the mixing ratio of the first
and the second artificial hair is 80:20 in mass ratio. In the first
belt portion 11d, the top portion 11c, and the forehead portion
11b, the first artificial hair having bending rigidity
7.8.times.10.sup.-3 gfcm.sup.2/strand and the second artificial
hair having bending rigidity 6.5.times.10.sup.-3 gfcm.sup.2/strand
are uniformly mixed and attached. Here, the mixing ratio of the
first and the second artificial hair is 80:20 in mass ratio.
[0166] In the sixth to the eighth embodiments, like the fifth
embodiment in the preferable case of a wig shown as the second to
the fourth embodiments, the second polyester fiber artificial hair
can further suppress the bundling tendency of a polyamide fiber as
the first artificial hair, and hair styles of flow feeling can be
formed.
[0167] In the first to the eighth embodiments, a case is shown
wherein the hairs of different bending rigidities are attached to
respective regions of a front hiding type wig, but the hairs of
different curling diameters and/or lengths may be attached further
to respective five regions in the cases of the first to the eighth
embodiments. Explanation is made of the examples as the ninth and
the tenth embodiments wherein the hair the curl diameter and the
length of which are further determined for the respective portions
in the first embodiment is attached, but it may be the case wherein
bending rigidities are substantially equal regardless of the wig
base regions, and the curl diameters and/or the lengths are
different.
[0168] Explanation is made of a ninth embodiment of the pattern to
attach hair to a wig base 11. FIG. 18 is a table showing the
properties of the hair attached to a wig base 11 in a ninth
embodiment of attaching patterns. The difference of the ninth
embodiment from the first embodiment is that the hair attached to
the peripheral portion 11a, the forehead portion 11b, the top
portion 11c, the first belt portion 11d, and the second belt
portion 11e not only has the pre-determined bending rigidity for
respective portions to be attached but also has the pre-determined
curl diameter and/or length for respective portions.
[0169] In the peripheral portion 11a is attached the hair having a
curl diameter 35 mm, a length 9 cm, and bending rigidity
3.9.times.10.sup.-3 gfcm.sup.2/strand. In the forehead portion 11b
is attached the hair having a curl diameter 23 mm, a length 7 cm,
and bending rigidity 6.5.times.10.sup.-3 gfcm.sup.2/strand. In the
top portion 11c is attached the hair having a curl diameter 26 mm,
a length 6 cm, and bending rigidity 6.5.times.10.sup.-3
gfcm.sup.2/strand. In the first belt portion 11d is attached the
hair having a curl diameter 28 mm, a length 7 cm, and bending
rigidity 6.5.times.10.sup.-3 gfcm.sup.2/strand. In the second belt
portion 11e are attached the hair having a curl diameter 32 mm, a
length 8 cm, and bending rigidity 3.9.times.10.sup.-3
gfcm.sup.2/strand and the hair having a curl diameter 32 mm, a
length 8 cm, and bending rigidity 6.5.times.10.sup.-3
gfcm.sup.2/strand mixed half to half.
[0170] Explanation is made of a tenth embodiment of the pattern to
attach hair to a wig base 11. FIG. 19 is a table showing the
properties of the hair attached to a wig base 11 in a tenth
embodiment of attaching patterns. The difference of the tenth
embodiment from the first embodiment is that the hair attached to
the peripheral portion 11a, the forehead portion 11b, the top
portion 11c, the first belt portion 11d, and the second belt
portion 11e not only has the pre-determined bending rigidity for
respective portions to be attached but also has the pre-determined
curl diameter and/or length for respective portions.
[0171] In the peripheral portion 11a is attached the hair having a
curl diameter 40 mm, a length 10 cm, and bending rigidity
3.9.times.10.sup.-3 gfcm.sup.2/strand. In the forehead portion 11b
is attached the hair having a curl diameter 30 mm, a length 8 cm,
and bending rigidity 6.5.times.10.sup.-3 gfcm.sup.2/strand. In the
top portion 11c is attached the hair having a curl diameter 35 mm,
a length 7 cm, and bending rigidity 6.5.times.10.sup.-3
gfcm.sup.2/strand. In the first belt portion 11d is attached the
hair having a curl diameter 35 mm, a length 8 cm, and bending
rigidity 6.5.times.10.sup.-3 gfcm.sup.2/strand. In the second belt
portion 11e are attached the hair having a curl diameter 40 mm, a
length 9 cm, and bending rigidity 3.9.times.10.sup.-3
gfcm.sup.2/strand and the hair having a curl diameter 40 mm, a
length 9 cm, and bending rigidity 6.5.times.10.sup.-3
gfcm.sup.2/strand mixed half to half.
[0172] As the ninth and the tenth embodiments, an example was
explained wherein the hair having the pre-determined curl diameter
and length further for respective portions in the first embodiment,
but, likewise in the second to the eighth embodiments, a wig may be
constituted by attaching the hair the curl diameter and length of
which are pre-determined for respective portions.
[0173] Explanation is next made of a top wearing type wig.
[0174] FIG. 20 is a table showing the properties of the hair
attached to a wig base 31 in eleventh to thirteenth embodiments of
attaching patterns. Explanation is made of an eleventh embodiment
of the pattern to attach hair to a wig base 31. Said eleventh
embodiment is suitable to an ordinary wearer. The hair attached to
the wig base 31 is made of a polyamide fiber of a sheath/core
structure. In the total peripheral region 31A of the wig base 31 is
attached the artificial hair having bending rigidity
3.9.times.10.sup.-3 gfcm.sup.2/strand which is about 40% lower than
the minimum value of that of natural hair (about
6.5.times.10.sup.-3 gfcm.sup.2/strand). In the adjustment region
31C of its inside are attached the artificial hair having bending
rigidity 3.9.times.10.sup.-3 gfcm.sup.2/strand and the artificial
hair having bending rigidity 6.5.times.10.sup.-3 gfcm.sup.2/strand
uniformly distributed so that the mass ratio becomes half to half.
In the region 31B of the top portion 31e of its inside is attached
the artificial hair having bending rigidity 6.5.times.10.sup.-3
gfcm.sup.2/strand. Here, bending rigidities of natural hair have a
personal deviation, and the hair growing on the scalp of a person
who needs a wig has low bending rigidity in general. The wig of the
eleventh embodiment is assumed as the case wherein the bending
rigidity of the wearer's own hair is about 3.4 to
4.4.times.10.sup.-3 gfcm.sup.2/strand.
[0175] Thus, while the hair attached to the total peripheral region
31A of the wig base 31 has bending rigidity lower than that of
average natural hair, that is, bending rigidity of the same level
as that of the wearer's own hair, the hair attached to the region
31B of the top portion 31e where the hair is not likely to be mixed
with the wearer's own hair has high bending rigidity compared with
the hair attached to the total peripheral region 31A. Therefore,
since the hair attached to the total peripheral region 31A of the
wig base 31 is easily blended well with the remaining hair growing
on the wearer's scalp, and shows similar behavior to the wearer's
own hair by the influence of such circumstances as humidity, it is
not likely for wig wearing to be recognized. In addition, since the
hair attached to the region 31B of the top portion 31e and to the
adjustment region 31C has higher bending rigidity than the wearer's
remaining hair, bulky feeling can be easily attained, and various
hair styles can be made in response to the wearer's needs.
[0176] Explanation is made of a twelfth embodiment of the pattern
to attach hair to a wig base 31. Its difference from the eleventh
embodiment is that the hair attached to the region 31B of the top
portion 31e of the wig base 31 and the hair uniformly mixed and
attached to the adjustment region 31C have low rigidities. It is
the same case as in the eleventh embodiment that the hair is made
of a polyamide fiber of a sheath/core structure. Artificial hair
having bending rigidity 3.9.times.10.sup.-3 gfcm.sup.2/strand is
attached to the total peripheral region 31A of the wig base 31. In
the adjustment region 31C inside it are attached artificial hair
having bending rigidity 3.9.times.10.sup.-3 gfcm.sup.2/strand and
artificial hair having bending rigidity 5.2.times.10.sup.-3
gfcm.sup.2/strand uniformly distributed so that the mass ratio
becomes half to half. Artificial hair having bending rigidity
5.2.times.10.sup.-3 gfcm.sup.2/strand is attached to the region 31B
of the top portion 31e further inside.
[0177] The twelfth embodiment differs from the eleventh embodiment
in that bending rigidity of the hair attached to the region 31B of
the top portion 31e is low compared with the eleventh embodiment,
and the whole hair attached to the wig is so designed as to have
lower bending rigidity than natural hair, so that it is suitable to
the wearer having comparatively soft hair, that is, suitable to the
user having hair of bending rigidity about 3.1 to
4.7.times.10.sup.-3 gfcm.sup.2/strand.
[0178] Explanation is made of a thirteenth embodiment of the
pattern to attach hair to a wig base 31. Its difference from the
eleventh embodiment is that, contrary to the twelfth embodiment,
the hair attached to the region 31B of the top portion 31e of the
wig base 31 and the hair attached to the adjustment region 31C
mixed therein have strengthened rigidities. It is the same case as
in the eleventh embodiment that the hair is made of a polyamide
fiber of a sheath/core structure. Artificial hair having bending
rigidity 3.9.times.10.sup.-3 gfcm.sup.2/strand is attached to the
total peripheral region 31A of the wig base 31. In the adjustment
region 31C inside it are attached artificial hair having bending
rigidity 5.2.times.10.sup.-3 gfcm.sup.2/strand and artificial hair
having bending rigidity 6.5.times.10.sup.-3 gfcm.sup.2/strand
uniformly distributed so that the mass ratio becomes half to half.
Artificial hair having bending rigidity 6.5.times.10.sup.-3
gfcm.sup.2/strand is attached to the region 31B of the top portion
31e inside.
[0179] Different from the eleventh embodiment, bending rigidity of
the hair attached to the top portion 31e is high compared with the
eleventh embodiment to increase the difference from natural hair,
bulky and rough feeling can be attained, thereby hair styles so far
not realized, for example, with standing hair can be formed.
Therefore, it is suitable to the wearers requiring hair styles of
bulky feeling. The wig of the thirteenth embodiment is assumed for
the case wherein the wearer's own hair has bending rigidity about
3.4 to 4.4.times.10.sup.-3 gfcm.sup.2/strand.
[0180] In the eleventh to the thirteenth embodiments above, a case
is shown wherein the hairs of different bending rigidities are
attached to respective regions of a top wearing type wig, but as
described before, like the fifth to the eighth embodiments for the
front hiding type wig, the first artificial hair made of a
polyamide fiber of a sheath/core structure and the second
artificial hair made of a polyester fiber may be used as the hair
attached to the wig base 31. Also, the hairs of different curling
diameters and/or lengths may be attached further to respective five
regions in the cases of the eleventh to the thirteenth embodiments.
Explanation is made of the examples as the fourteenth and the
fifteenth embodiments wherein the hair, the curl diameter and the
length of which are further determined for the respective portions
in the eleventh embodiment is attached, but it may be the case
wherein bending rigidities are substantially equal regardless of
the wig base regions, and the curl diameters and/or the lengths are
different.
[0181] Explanation is made of the fourteenth embodiment of the
pattern to attach hair to a wig base 31. FIG. 21 is a table showing
the properties of the hair attached to a wig base 31 in a
fourteenth embodiment of attaching patterns. In the fourteenth
embodiment, the regional partition wherein the hair of the
pre-determined bending rigidity is attached in the wig base 31 and
the regional partition wherein the hair of the pre-determined curl
diameter and/or length is attached are separately determined.
Namely, in the main region 31B as a top portion 31e, the hair of
the curl diameter 30 mm, the length 18 cm, and bending rigidity
6.5.times.10.sup.-3 gfcm.sup.2/strand is attached. In the forehead
portion 31a of the total peripheral region 31A, the hair of the
curl diameter 30 mm, the length 15 cm, and bending rigidity
3.9.times.10.sup.-3 gfcm.sup.2/strand is attached. In the left and
right side head portions 31b and 31c of the total peripheral region
31A, the hair of the curl diameter 35 mm, the length 20 cm, and
bending rigidity 3.9.times.10.sup.-3 gfcm.sup.2/strand is attached.
In the rear head portion 31d of the total peripheral region 31A,
the hair of the curl diameter 45 mm, the length 30 cm, and bending
rigidity 3.9.times.10.sup.-3 gfcm.sup.2/strand is attached. In the
forehead portion 31a of the adjustment region 31C, the hair of the
curl diameter 30 mm, the length 15 cm, and bending rigidity
3.9.times.10.sup.-3 gfcm.sup.2/strand and the hair of the curl
diameter 30 mm, the length 15 cm, and bending rigidity
6.5.times.10.sup.-3 gfcm.sup.2/strand are mixed half to half in the
mass ratio and attached. In the left and right side head portions
31b and 31c of the adjustment region 31C, the hair of the curl
diameter 35 mm, the length 20 cm, and bending rigidity
3.9.times.10.sup.-3 gfcm.sup.2/strand and the hair of the curl
diameter 35 mm, the length 20 cm, and bending rigidity
6.5.times.10.sup.-3 gfcm.sup.2/strand are mixed half to half in the
mass ratio and attached. In the rear head portion 31d of the
adjustment region 31C, the hair of the curl diameter 45 mm, the
length 30 cm, and bending rigidity 3.9.times.10.sup.-3
gfcm.sup.2/strand and the hair of the curl diameter 45 mm, the
length 30 cm, and bending rigidity 6.5.times.10.sup.-3
gfcm.sup.2/strand are mixed half to half in the mass ratio and
attached.
[0182] Explanation is made of the fifteenth embodiment of the
pattern to attach hair to a wig base 31. FIG. 22 is a table showing
the properties of the hair attached to a wig base 31 in a fifteenth
embodiment of attaching patterns. In the fifteenth embodiment, as
in the fourteenth embodiment, the regional partition wherein the
hair of the pre-determined bending rigidity is attached in the wig
base 31 and the regional partition wherein the hair of the
pre-determined curl diameter and/or length is attached are
separately determined. Namely, in the main region 31B as a top
portion 31e, the hair of the curl diameter 40 mm, the length 25 cm,
and bending rigidity 6.5.times.10.sup.-3 gfcm.sup.2/strand is
attached. In the forehead portion 31a of the total peripheral
region 31A, the hair of the curl diameter 35 mm, the length 20 cm,
and bending rigidity 3.9.times.10.sup.-3 gfcm.sup.2/strand is
attached. In the left and right side head portions 31b and 31c of
the total peripheral region 31A, the hair of the curl diameter 45
mm, the length 30 cm, and bending rigidity 3.9.times.10.sup.-3
gfcm.sup.2/strand is attached. In the rear head portion 31d of the
total peripheral region 31A, the hair of the curl diameter 60 mm,
the length 35 cm, and bending rigidity 3.9.times.10.sup.-3
gfcm.sup.2/strand is attached. In the forehead portion 31a of the
adjustment region 31C, the hair of the curl diameter 35 mm, the
length 20 cm, and bending rigidity 3.9.times.10.sup.-3
gfcm.sup.2/strand and the hair of the curl diameter 35 mm, the
length 20 cm, and bending rigidity 6.5.times.10.sup.-3
gfcm.sup.2/strand are mixed half to half in the mass ratio and
attached. In the left and right side head portions 31b and 31c of
the adjustment region 31C, the hair of the curl diameter 45 mm, the
length 30 cm, and bending rigidity 3.9.times.10.sup.-3
gfcm.sup.2/strand and the hair of the curl diameter 45 mm, the
length 30 cm, and bending rigidity 6.5.times.10.sup.-3
gfcm.sup.2/strand are mixed half to half in the mass ratio and
attached. In the rear head portion 31d of the adjustment region
31C, the hair of the curl diameter 60 mm, the length 35 cm, and
bending rigidity 3.9.times.10.sup.-3 gfcm.sup.2/strand and the hair
of the curl diameter 60 mm, the length 35 cm, and bending rigidity
6.5.times.10.sup.-3 gfcm.sup.2/strand are mixed half to half in the
mass ratio and attached.
[0183] Explanation was made of an example wherein the hairs of the
pre-determined curl diameter and length for respective portions
were further attached in the eleventh embodiment as the fourteenth
and the fifteenth embodiments, but a wig may be constituted
likewise by attaching the hair of the pre-determined curl diameter
and length for respective portions in the twelfth and the
thirteenth embodiments.
[0184] Thus, since it is possible to attach the hair of high
bending rigidity in the regions of top portions 11c and 31e of the
wig base 11 and 31, it is not necessary to make wave shapes at fine
intervals near the roots of hair upon hair attaching process, that
is, to make the hair stand up after attaching by so-called crimping
process, thereby not causing crimped hair by crimping process, nor
spoiling the appearance. Also, since it is not necessary to make
high hair density attached to the wig base 11 and 31, the
appearance of hair styles itself does not change.
[0185] Not limited to the above-described attaching patterns, the
present invention may be properly modified within the range of the
claimed invention. For example, not only bending rigidity of hair,
but also the length, diameter, color, and such other properties as
the curl size given to the hair may be adjusted depending upon the
regions of the hair attached to a wig base, to form the wearer's
preferred hair style without exposing wig wearing.
