A hair material for a wig is preliminarily curled and then bound
to a wig base to thereby orient the curled hair in a definite
direction. A folded part (10c) of a hair material (10) is
penetrated from one side of a filament (15) to the other side under
a wig base (12) so that a first loop (17) is formed in the inner
side of the folded part (10c). A curved part (10d) is inserted
though the first loop (17) so that a second loop (19) is formed in
the inner side of the curved part (10d). A part (10b) of the hair
material is inserted through the second loop (19). Next, the hair
material parts (10a, 10b) are pulled in directions opposite to each
other and tied with the filament (15) to (20). Thus, the hair
material (10) is bound to the filament (15).

Description
TECHNICAL FIELD
[0001] The present invention relates to a wig to be worn to a head
in full or in part, and more specifically, to a wig comprising a
wig base and curled hair materials fixed to the wig base.
BACKGROUND ART
[0002] Conventionally, hair materials used for wigs have generally
been straight hairs. In recent years, however, there are a variety
of hair styles. Particularly, in case the user is a lady, an
elegant and unique fashionableness in hair styles as well as
increase of hair in volume is quite often required, and it is
difficult to meet such requirements of various hair styles with
straight hairs, which only provide a rather low flexibility.
[0003] To solve this problem, there is known, for example, a
technique as disclosed in Japan Patent Application Laid-open
64-40606 A. According to the technique disclosed in this
specification, a hair material is folded into two, the folded
portion is fastened to the front portion of a wig base, the hair
material is curled or turned over toward in the outward direction,
and then the curled hair material is set to wave from the front
side toward the rear side of the wig base.
[0004] However, according to the above-described configuration, in
which curl is imparted to all the hair materials fastened to the
wig base through post-processing, the folded portion 1a of each
hair material 1 is already fixed to a wig base 2 as shown in FIG.
21, so it is impossible to secure a sufficient length for the
remaining hair piece 1b to impart curl thereto. As a result, the
hair piece 1b can not be sufficiently wound around a curl imparting
means 3 such as a rod or a curler, and it is likely to result in
loose curl, making it rather difficult to impart a predetermined
curl diameter.
[0005] In case curl is imparted through heat treatment, there is a
fear of the heat resistance of the wig base 2 being rather
insufficient. If the heat treatment can not be conducted at a
predetermined high temperature, it is not possible to maintain curl
for a long period of time.
[0006] Further, since imparting curl through post-processing is the
same way as perming the natural hair, it takes time and effort,
resulting in a rather low efficiency.
[0007] In view of this, it might be conceivable to fasten a hair
material with the hair pieces previously curled to a wig base.
However, as shown in FIG. 22, in case the folded portion 1a is
fastened to the base 2 in a general manner, the curls of the hair
pieces 1b are oriented to various directions. Thus, even if the
hair material 1 is combed, it is impossible to align the curl of
the hair pieces in a predetermined direction. It results not only
in leading to a rather poor outward appearance but also in not
obtaining a desired hair fashion.
[0008] The present invention has been made in view of the above
problem. It is an object of the present invention to provide a wig
allowing orientation of the curl of a hair material in a
predetermined direction after being fastened to a wig base even in
the case of hair material curled in advance. Another object of the
present invention is to provide a wig capable of maintaining the
curl imparted to the hair pieces for a long period of time.
DISCLOSURE OF THE INVENTION
[0009] To achieve the object described above, a wig according to
the present invention comprises a wig base to be worn to a head;
and a large number of hair materials fastened to the wig base, each
being a pair of hair pieces folded into two, wherein curls are
imparted in advance to the pair of hair pieces before being
fastened to the wig base, wherein a folded portion of the pair of
hair pieces is fixed to the wig base while tips of the pair of hair
pieces are being oriented to a predetermined direction with respect
to the wig base, thereby the curls of the pair of hair pieces are
oriented to a predetermined direction after being fixed to the wig
base.
[0010] The fixation of the hair material to the wig base can be
effected by fastening, transplanting, etc. When the wig base is of
a net-like configuration, the hair material is fixed to the wig
base by fastening the folded portion between the two hair pieces to
a filament of the net. When the wig base is of a sheet-like
configuration, the hair material is fixed to the wig base by
fastening or transplanting the folded portion between the two hair
pieces to the filament.
[0011] According to the present invention, the curls of the pair of
hair pieces may be imparted by a method comprising the steps of
applying a first cold permanent liquid to the weft containing a
predetermined number of the hair materials in each of a
predetermined number of pitches and impregnating a sheet of
non-woven fabric with water; placing the weft on the sheet and
combing the weft to thereby uniformly distribute the hair materials
on the sheet; winding the weft and the sheet integrally around a
pipe; keeping them in this state sealed in a bag for a
predetermined period of time; applying a second cold permanent
liquid to the hair materials extracted from the bag after the
predetermined period of time has elapsed; winding the weft and the
sheet integrally around the pipe; keeping them in this state for
further predetermined period of time; and washing in water the weft
wound off after the further predetermined period of time has
elapsed.
[0012] According to the present invention, the curls of the pair of
hair pieces may be imparted by a method comprising the steps of
applying a conditioner for chemical fibers to the weft containing a
predetermined number of the hair materials in each of a
predetermined number of pitches; placing the weft on a sheet of one
of non-woven fabric and paper and combing the weft to thereby
uniformly distribute the hair materials on the sheet; winding the
weft and the sheet integrally around a pipe; and heating them in
this state for a predetermined period of time.
[0013] According to the present invention, the curls of the pair of
hair pieces may be imparted by a method comprising the steps of
impregnating the weft containing a predetermined number of the hair
materials in each of a predetermined number of pitches and a sheet
of non-woven fabric with an aqueous solution of silicon emulsion;
placing the weft on the sheet and combing the weft to thereby
uniformly distribute the hair materials on the sheet; winding the
weft and the sheet integrally around a pipe and covering them with
an aluminum foil; and heating them in this state for a
predetermined period of time.
[0014] According to the present invention, the curls of the pair of
hair pieces may be imparted by a method comprising the steps of:
immersing the weft containing a predetermined number of the hair
materials in each of a predetermined number of pitches and a sheet
of non-woven fabric in an aqueous solution of silicon emulsion;
placing the weft on the sheet material and combing the weft to
thereby uniformly distribute the hair materials on the sheet
material; winding the weft and the sheet integrally around a pipe
and drying them; and heating them in this state for a predetermined
period of time.
[0015] According to the present invention, the third and fourth
steps of the just prior embodiment may be replaced with the steps
of: winding the weft and the sheet integrally around a pipe and
covering them with an aluminum foil; and heating them in this state
for a predetermined period of time.
[0016] As the hair materials of the present invention, apart from
human hairs, it is also possible to use, hairs of synthetic resin
such as acrylic resin, modacrylic resin or polyamide resin. As the
wig base to which this hair material is to be fastened, there is
used a filament or a sheet-shaped base obtained by knitting
synthetic fibers (chemical fibers), vegetable fibers, animal
fibers, etc. into a net-like form. From the viewpoint of stability
in performance, durability, cost, etc., it is desirable to use
synthetic fibers, such as nylon or polyester. As the sheet-like
member to be used as a guide in winding around a pipe member,
non-woven fabric, paper, etc. are suitable. A non-woven fabric of
rayon, polyester or the like, which increases in surface frictional
force when moistened to thereby prevent slippage, is more
preferable.
[0017] As the weft to be used in the present invention, a plurality
of hair materials cut in a predetermined length are preferably
arranged at intervals, and sewn together at appropriate positions
in the length direction of the hair materials to form a sewn
bundle. When the lateral width of the weft is too large, it is
rather difficult to apply uniform tension to the winding pipe
member in the operation of winding it around the winding pipe
member. It is thus desirable for the lateral width of the weft to
be 20 cm or less.
[0018] Since chemical fiber hairs after imparting curl thereto is
hardened, a conditioner is applied to the weft to improve the
texture thereof. As the conditioner, it is desirable to use a
conditioner for chemical fibers containing 20 to 30% of a
surface-active agent composed of nonions, cations or a mixture
thereof. When the content of the surface-active agent exceeds 30%,
the surface of the hair material 10 becomes sticky or the tone
thereof is changed during the heat treatment after the imparting of
curl. When the content of the surface-active agent is less than
20%, an improvement in texture after the imparting of curl is
hardly to be observed.
[0019] According to the present invention in Claims 1 through 6,
the direction of the curl of the hair pieces is determined
depending upon the direction in which the hair materials are
fastened to the wig base, and a predetermined hair design results.
For example, when the hair materials are fixed to the wig base in a
state in which they are aligned in the same direction, the curl of
the hair pieces of these hair materials is aligned in the same
direction. When a large number of hair materials are fastened to
the wig base in fixed amounts in different directions, the curls of
the hair pieces of these hair materials are oriented in different
directions. Thus, through appropriate selection of hair material
fixing directions with respect to the wig base, it is possible to
obtain wigs for a variety of hair designs. Further, it is possible
to maintain the curl imparted to the hair pieces of the hair
materials in a satisfactory state for a long period of time. In the
construction of the present invention, the hair materials are fixed
to the wig base with their directions determined, so the direction
of the curl of the hair pieces is determined. Thus, after fixing
the hair materials to the wig base, it is possible to easily obtain
a wig in which the hair piece curl is oriented in a predetermined
direction. Further, through this hair material attachment, it is
possible to apply the wig not only to a basic hair design, but also
to a complicated hair design with intermingled curl directions,
making it possible to attain a hair design of high degree of
freedom. Thus, as compared with the conventional wig, in which the
curl direction is not fixed even if the hair materials are combed
and which is rather poor in terms of design, it is possible to
obtain a product that is more perfect as such.
[0020] Further, by forming a pair of hair pieces aligned in the
same curl direction, when the hair material is fastened to the wig
base, it is possible to orient the hair piece curl in a
predetermined direction more easily, with the hair piece not being
easily allowed to wave in any other direction. Further, as compared
with the conventional technique, in which curling processing is
effected after fastening the hair materials to the wig base, a
predetermined curl size can be imparted more easily and the curling
operation can be performed in a shorter time. It is further
possible to maintain the curl configuration imparted to the hair
materials in a satisfactory manner for a long period of time.

BEST MODE FOR CARRYING OUT THE INVENTION
[0043] In the following, embodiments of the present invention will
be described with reference to FIGS. 1 through 20. Of the drawings,
FIGS. 1 through 5 show the first embodiment of the present
invention. FIGS. 1(a) through 1(e) are plan views illustrating the
operation of fastening a hair material to a filament of a wig base
in the form of a net, FIG. 2 is a perspective view of a wig, FIG. 3
is a perspective view of a weft, FIGS. 4(a) through 4(d) are
perspective views of a single hair material, and FIG. 5 is a front
view of hair materials as fastened to a filament of a wig base.
[0044] In the first embodiment of the present invention shown in
FIGS. 1 through 5, a large number of hair materials 10 are fastened
to a wig base 12 as hair 11 to form a wig 13 as shown in FIG. 2. As
the hair materials 10, human hairs or synthetic resin hairs are
used. In the state of a weft 14 prior to the fastening to the wig
base 12, curl is imparted to hair pieces 10a, 10b beforehand. When
large number of hair materials 10 are fastened to the wig base 12,
there is formed a hair design in which the hair 11 equally parted
in the middle is curled symmetrically.
[0045] As shown in FIGS. 1 through 5, the wig base 12 is composed
of an artificial skin or a net of synthetic resin shaped into a
head configuration. In this embodiment, the hair materials 10 are
fastened to filaments 15 forming a net constituting the wig base
12. The weft 14 is obtained by sewing together a plurality of hair
materials 10 cut in a predetermined length at a predetermined
longitudinal position with a sewing thread 16. The weft is wound
around a cylindrical member such as a pipe member (not shown) and
is subjected to heat treatment, so curl is imparted to the hair
pieces 10a, 10b of the hair materials 10 as shown in FIG. 2.
[0046] A hair material 10 is drawn out of the weft 14 whose hair
pieces 10a, 10b are thus curled beforehand. The hair material 10
thus drawn out is folded into two to form a pair of hair pieces
10a, 10b curled in the same direction and a folded portion 10c
folded between the hair pieces 10a, 10b. The hair pieces 10 thus
folded into two are classified into, as shown in FIG. 2, right-hand
side curl hair pieces for use on the right-hand side with respect
to the middle parting portion of the wig 13 and left-hand side curl
hair pieces for use on the left-hand side with respect to the
middle parting portion so as to be fastened to the wig base 12.
[0047] As shown in FIGS. 4(a) and 4(b), the right-hand curl hair
piece 10 is retained with the tips of the hair pieces 10a, 10b on
the right-hand side and the curved folded portion 10c on the
left-hand side. When hair piece portions in the vicinity of the
folded portion 10c are held between a left thumb and a left index
finger, the two hair pieces 10a, 10b are curled so as to be wound
around the left index finger.
[0048] As shown in FIGS. 4(c) and 4(d), the left-hand curl hair
piece 10 is retained with the tips of the hair pieces 10a, 10b on
the left-hand side and the curved folded portion 10c on the
right-hand side. When hair piece portions in the vicinity of the
folded portion 10c are held between a left thumb and a left index
finger, the two hair pieces 10a, 10b are curled so as to be wound
around the left thumb. While in FIGS. 4(b) and 4(d) the hair pieces
10a, 10b are shown as held between fingers for the sake of
convenience to facilitate the understanding of the hair piece
curling direction, in reality, the hair materials 10 are fastened
to the wig base 12 while being grasped by a mechanical grasping
means.
[0049] In the process shown in FIGS. 1(a) through 1(e), the
right-hand curl hair material 10 held as shown in FIGS. 4(a) and
4(b) is fastened to a filament 15 forming a net as the wig base 12
through mechanical operation of a crochet 18.
[0050] In fastening the right-hand curl hair material 10 to the
filament 15, while grasping the hair material 10 by a mechanical
grasping means (not shown) such that the two hair pieces 10a, 10b
are directed to the right with respect to the wig base 12, the
folded portion 10c of the hair material 10 is situated on the lower
side (a side to be worn to a head) of the filament 15, and the hair
pieces are caused to cross each other so that one hair piece 10a
comes over the other hair piece 10b as shown in FIG. 1(a), thereby
forming a first loop portion 17 on the inner side of the folded
portion 10c.
[0051] Next, as shown in FIG. 1(b), the folded portion 10c is
brought in the direction of the filament 15, and one hair piece 10a
is passed through the first loop portion 17 while being folded as
shown in FIG. 1(c), so a curved portion 10d is formed in the middle
portion of one hair piece 10a drawn out of the first loop portion
17, and a second loop portion 19 is formed on the inner side of the
curved portion 10d.
[0052] Subsequently, as shown in FIG. 1(d), the other hair piece
10b is passed through the second loop portion 19 so as to be wound
around one hair piece 10a from the outside, and as shown in FIG.
1(e), the hair pieces 10a, 10b are pulled in opposite directions
each other, and the filament 15 is bound by a knot 20, so the hair
material 10 is fastened to the filament 15.
[0053] The hair material 10 of this embodiment having right-hand
curl in the hair pieces 10a, 10b is fastened to the filament 15 in
this way. As a result, as shown in FIG. 5(a), the hair pieces 10a,
10b are oriented with their curls aligned to the right with respect
to the filament 15 of the wig base.
[0054] The left-hand curl hair material 10 shown in FIGS. 4(c) and
4(d) are also fastened to the filament 15 by the same process as
that for the right-hand curl hair material 10 described above, and
as shown in FIG. 5(b), the hair pieces 10a, 10b are oriented with
their curls aligned to the left.
[0055] As described above, in this embodiment, the folded portion
10c is fastened to the filament 15 through mechanical operation of
the crochet 18 while grasping the tips of the previously curled
hair pieces 10a, 10b by a separate grasping means such that they
are oriented in a predetermined direction, i.e., either to the
right or to the left, with respect to the wig base 12, so it is
possible to easily obtain a wig 11 of a design in which the
right-hand curl and left-hand curl imparted to the hair pieces 10a,
10b are orderly parted on the right-hand and left-hand sides of the
wig base 12.
[0056] Thus, it is possible to avoid a situation as experienced in
the prior art in which the curl directions of the hair pieces 10a,
10b fastened to the wig base 12 are not fixed, and there is no need
to perform a post-processing, such as alignment of the curls of the
hair pieces 10a, 10b by combing the hair material 10 after the
attachment thereof, so it is possible to obtain a product superior
not only in operability and productivity but also in completeness
as such.
[0057] Next, the second embodiment of the present invention will be
described with reference to FIG. 6. FIGS. 6(a) through 6(c) are
plan views for illustrating the operation of fastening a previously
curled hair material to a wig base. The hair material 10, the wig
base 12, the filament 15, and the crochet 18 are the same as those
of the first embodiment.
[0058] As in the first embodiment shown in FIGS. 1(a) through 1(e),
in the second embodiment shown in FIGS. 6(a) through 6(c), in
fastening the previously curled hair material 10 to the filament 15
of the wig base 12, the hair material is grasped by a mechanical
grasping means (not shown) such that the curls of the two hair
pieces 10a, 10b are oriented in a predetermined direction with
respect to the wig base 12. As shown in FIG. 6(a), the folded
portion 10c of the hair material 10 is situated on the lower side
(head side) of the filament 15, and the hair pieces are caused to
cross each other such that one hair piece 10a comes over the other
hair piece 10b, forming a first loop portion 21 on the inner side
of the folded portion 10c.
[0059] In FIG. 6(b), the folded portion 10c is wound from the lower
side to the upper side of the filament 15, and the other hair piece
10b is passed through the loop portion 21. Further, the entire
other hair piece 10b is drawn out of the loop portion 21, and the
hair pieces 10a, 10b are pulled each other in opposite directions,
and the filament 15 is bound by a knot 22, so the hair material 10
is fastened to the filament 15.
[0060] While in the first and second embodiments described above, a
net-shaped wig base using filament is adopted, it is also possible,
in the present invention, to use a sheet-like member composed of an
artificial skin or the like formed of synthetic resin as the wig
base. In this case, to fasten the hair materials to the sheet-like
wig base, a large number of through-holes are provided in the
sheet-like member, and two through-holes, i.e., a first
through-hole and a second through-hole are used per hair material,
the hair material being fastened regarding these through-holes as
both sides of the filament of the first and second embodiments.
Further, when the wig base composed of a sheet-like member, the
fixation of the hair material can also be effected by
transplanting, in which case the sheet-like member is pierced by
the folded portion of the hair material, and a detachment
preventing means is provided at the tip of the folded portion
protruding from the lower side of the sheet-like member.
[0061] Next, procedures by which curl is imparted to the hair
pieces 10a, 10b of the hair material 10 used in the above
embodiments will be described with reference to the third through
sixth embodiments shown in FIGS. 7 through 16. In describing the
third through sixth embodiments, FIGS. 1 through 6 in the above
will also be referred if necessary.
[0062] Of the drawings, FIGS. 7 through 16 show the third
embodiment. FIG. 7 is a perspective view illustrating the operation
of blending hair materials, FIG. 8 is a plan view of a sewn weft,
FIG. 9 is a plan view of a weft as placed on a sheet material, FIG.
10 is a plan view of a weft placed on a sheet material as combed,
FIG. 11 is a sectional view of a weft on a sheet material, FIG. 12

are wound around a pipe member, FIG. 13 is a sectional view showing
a weft and a sheet material as wound around a pipe member, FIG. 14
is a perspective view showing, like FIG. 13, hair a tuft and a
sheet material as wound around a pipe member, FIG. 15 is a front
view of a hair material as fastened to a filament, and FIG. 16 is a
plan view of hair materials drawn out of hair a tuft.
[0063] The third embodiment shown in FIGS. 7 through 16 is suitable
for imparting curl to human hairs as the hair materials 10
(including human hairs from which the cuticles have been removed
and which have undergone bleaching and dyeing processes so as to be
suitable for use in a wig). First, as shown in FIGS. 7(a) and 7(b),
a hair bundle 30 formed by a plurality of hair materials 10
composed of human hairs of a plurality of desired colors is applied
to a hair comber 31, and the hair bundle 30 is repeatedly combed by
a teeth 31a of the hair comber 31 to thereby effect blending on the
hair materials 10 of a plurality of colors to a sufficient degree.
Even when the hair materials 10 are monochrome human hairs, the
hair bundle 30 is disentangled into unit hairs by putting it
through the hair comber 31. Next, the blended hair bundle 30 is cut
in a predetermined length. This predetermined length is a reference
length in fastening the hair materials 10 to the wig base 12.
[0064] FIG. 8(a) is a plan view of a weft 14 prepared by sewing
together an appropriate amount by weight of the hair materials 10
cut in a predetermined length at a predetermined longitudinal
position, and FIG. 8(b) is an enlarge view of the weft 14. The weft
14 thus formed has a plurality of sewn bundles 32. When a lateral
width 6L of the weft 14 shown in FIG. 8(a) is too large, it is
rather difficult to apply a uniform tension to an aluminum pipe
member 33 in the operation described below of winding the weft 14
around the pipe member 33, so it is desirable for the width to be
20 cm or less. Sewing marks 34 of sewing thread 16 are left in the
hair materials 10 in the process described below (see FIG. 16), so
the position where the sewing marks 34 of the sewing thread 16 are
left constitutes the folding position in fastening the hair
materials 10 to the wig base 12.
[0065] It is desirable for the weft 14 thus formed to contain 8 to
10 sewn bundles 32 per centimeter, and it is desirable for each
sewn bundle 32 to contain 12 to 27 hair materials 10. If the number
of sewn bundles 32 per centimeter were less than eight, the pitch
of the sewn bundles 32 would be too large, making it impossible to
uniformly distribute the hair materials 10 shown in FIG. 10.
Further, it would be difficult to wind the hair materials 10 around
the pipe member 33 at a fixed angle. Further, when combing the weft
14 prior to the winding so as to make it straight, the hair
materials 10 would be likely to be detached to the sewn bundles 32.
On the other hand, if the number of sewn bundles 32 per centimeter
were more than ten per centimeter, there would be no interval
between the sewn bundles 32, and the sewn portion would be rather
thick to constitute a step when wound around the pipe member 33 to
wrinkle the hair materials 10. Thus, so-called loose curl, which is
weaker than a predetermined curl, is likely to result. Further, if
the number of sewn bundles 32 per unit length is large, when sewing
is performed in the production of the weft 14, the hair materials
10 and the sewing thread 16 are likely to be entangled with each
other, and the sewing thread 16 is pulled, with the result that a
neat weft 14 cannot be obtained. Thus, the hair materials 10 are
wrinkled or rumpled after the imparting of curl thereto.
[0066] When the number of hair materials 10 in each sewn bundle 32
is less twelve or less, there is no problem in terms of the
imparting of curl. However, the length of the weft 14 becomes
rather large, and a large number of wefts 14 have to be produced in
order to prepare the requisite amount of hair materials 10, with
the result that the number of pipe members 33 around which the
wefts 14 are to be wound increases, resulting in an increase in
burden in terms of operation and cost. When the number of hair
materials 10 per sewn bundle 32 is twenty-seven or more, the
thickness of each sewn bundle 32 increases, and loose curl, which
is weaker than a predetermined curl, is likely to result.
[0067] FIGS. 9 and 11(a) show a state in which a first cold
permanent liquid has been sufficiently applied to the weft 14
formed as described above and in which the weft 14 has been placed
at a predetermined position on a sheet material 35 moistened and
spread on a working table. The weft 14 is combed so as to make it
straight, so the hair materials 10 are aligned in a row with no gap
therebetween as shown in FIGS. 10 and 11(b), thereby reducing the
thickness of the weft 14.
[0068] The sheet material 35 serves as a guide when winding the
weft 14 around the pipe member 33. At the time of use, it is
moistened and spread over and held in intimate contact with the
working table so as to involve no wrinkles. As the sheet material
35, non-woven fabric is preferable since it increases in surface
frictional force when moistened to prevent slippage. When it
involves slippage when moistened, it may cause spinning or generate
a gap between the weft and the aluminum pipe member 33 around which
it is wound, resulting in loose curl.
[0069] For this reason, as the material of the non-woven fabric for
the sheet material 35, rayon or polyester is preferable. More
preferably, a weight per unit area [metuske] of 18 to 30 g/m.sup.2
is adopted. When the weight per unit area [metuske] is 18 g/m.sup.2
or less, the density of the sheet material is rather small, and the
cold permanent liquid applied to the weft 14 is easily vaporized,
making it impossible to impart curl to a sufficient degree.
Further, at the time of operation of winding it around the pipe
member 33, the sheet material 35 is likely to suffer damage when
tension is applied thereto. On the other hand, when the weight per
unit area [metuske] is 30 g/m.sup.2 or more, the thickness of the
sheet material 35 is rather large, so that when it is wound around
the pipe member 33, a rather large diameter results as the winding
diameter increases, and the tuft 14 is likely to assume loose curl,
which is weaker than curl of a predetermined configuration.
[0070] In the subsequent process shown in FIG. 12, an aluminum pipe
member 33 with a circular sectional configuration is placed at one
end of the sheet material 35, and the weft 14 and the sheet
material 35 are wound integrally around the pipe 33 while applying
tension thereto, as shown in FIGS. 13 and 14, fixing the outer
center and both side ends of the tuft 14 by a fixing means 36, such
as an adhesive tape or a rubber band. Next, the pipe 33 around
which the weft 14 and the sheet material 35 have been wound is
sealed in a plastic bag (not shown) and left to stand for
approximately 15 minutes at room temperature. After that, a second
cold permanent liquid are directly applied to the sheet material 35
in the outer periphery of the pipe member 33 extracted from the
plastic bag, or to the disentangled weft 14 from the pipe member
33. Next, the weft 14 and the sheet material 35 are wound around
the pipe member 33 again and fixed by the fixing means 36 before
being left to stand for 15 minutes at room temperature.
[0071] After that, the fixing means 36 is released, and washing in
flowing water is effected while gradually releasing the weft 14 and
the sheet 35 wound around the pipe member 33, and the sheet
material 35 is spread over the working table so as to involve no
wrinkles. Next, the washed weft 14 is arranged at a predetermined
position on the sheet material 35, and hair rinse or conditioner is
applied to the weft 14. The application of the rinse or conditioner
is effected for the purpose of achieving an improvement in terms of
texture since the texture of the hair materials 13 that have
undergone treatment with the cold permanent liquid is rather
hard.
[0072] Next, the weft 14 is combed by the same process as that of
FIG. 10, and the hair materials 10 are uniformly distributed so as
to involve no gaps therebetween and to be aligned in a row, thereby
reducing the thickness of the weft 14. Next, by the same process as
that shown in FIGS. 12 through 14, the weft 14 and the sheet
material 35 are integrally wound around the pipe material 33.
Further, the weft 14 and the sheet material 35 are fixed in
position by a fixing means 36, such as an adhesive tape or a rubber
band, and the pipe member 33 is wrapped up in a towel or the like
to remove surplus water from the sheet material 35. After that,
they are left to stand at room temperature until the sheet material
35 wound around the pipe member 33 is completely dried, or dried in
a dryer at a temperature of approximately 90.degree. C. Finally,
the sheet material 35 and the weft 14 are extracted.
[0073] FIG. 15 shows a single hair material 10 thus curled. Each
hair material 10 has a sewing mark 34 at the position where sewing
has been effected with the sewing thread 16. When, by the sewing
process of FIG. 8, the middle points in the length direction of the
hair materials 10 are sewn together, the length of the hair pieces
10a, 10b of each hair material 10 fastened to a filament 15 of the
wig base 12 is half the total length of the hair material 10 as
shown in FIG. 15(a). The position at which the sewing is effected
with the sewing thread 16 is not restricted to the position where
the total length of the hair material 10 is equally divided. When
the sewing is effected with the sewing thread 16 at a position
somewhat deviated therefrom, the hair pieces 10a, 10b differ in
length as shown in FIG. 15(b), and when it is fastened to the
filament 15 of the wig base 12, it is possible to obtain an outward
appearance different from that obtained by effecting sewing at the
position equally dividing the hair material as shown in FIG.
15(a).
[0074] Next, the fourth embodiment of the present invention will be
described with reference to FIGS. 7 through 16, which are common to
the third embodiment. A detailed description of the components that
are the same as those of the third embodiment will be omitted. In
this embodiment, the hair material 10 is formed of an acrylic resin
or a modacrylic resin (copolymer of acrylic resin and vinyl
chloride) or the like. It is suitable for imparting curl to
chemical fiber hairs of low heat resistance and exhibiting a
softening temperature of 100.degree. C. or less.
[0075] In the fourth embodiment shown in FIGS. 7 through 16, the
processes of FIGS. 7 and 8 are the same as those of the third
embodiment. In the subsequent process shown in FIGS. 9 and 11(a), a
conditioner for chemical fibers is applied to the weft 14, and the
weft 14 is placed at a predetermined position on the sheet material
35 spread on the working table. The sheet material 35 serves as a
guide in winding the weft 14 around the pipe member 33, and when in
use, it is spread over and held in intimate contact with the
working table so as to involve no wrinkles. The weft 14 is combed
so as to make it straight, so the hair materials 10 are aligned in
a row with no gap therebetween as shown in FIGS. 10 and 11(b),
thereby reducing the thickness of the weft 14.
[0076] As the sheet material 35 of this embodiment, non-woven
fabric or paper is suitable. There are no particular limitations
regarding its nature except that the weight per unit area [metuske]
thereof is 40 to 50 g/m.sup.2. When the weight per unit area
[metuske] is not more than 40 g/m.sup.2, the density of the sheet
material 35 is rather low, and heat is allowed to be conducted
quickly at the time of heat treatment to impart curl. Thus, the
uppermost layer of the weft 14 wound around the aluminum pipe
member 33 is excessively heated, and shrinkage occurs in the
portion, resulting in a rather poor outward appearance, which leads
to a product of no commercial value. On the other hand, when the
weight per unit area [metuske] is 50 g/m.sup.2 or more, the
thickness of the non-woven fabric or paper increases, so that when
wound around the pipe member 33, it increases in diameter as the
winding diameter increases. Thus, the weft 14 is likely to result
in loose curl, which is weaker than curl of a predetermined
configuration. Further, the density of the non-woven fabric or
paper is rather high, so that the heat is cut off at the time of
heat treatment to impart curl, and the requisite heat for curling
is not applied, which is likely to lead to so-called loose curl,
which is weaker than curl of a predetermined configuration.
[0077] The conditioner for chemical fibers applied to the weft 14
is used for the purpose of achieving an improvement in terms of
texture since chemical fiber hairs become harder after the
imparting of curl. As the conditioner, it is desirable to adopt one
containing 20 to 30% of a surface-active agent composed of nonions
or cations or a mixture thereof. When the content of the
surface-active agent exceeds 30%, the surface of the hair materials
10 become sticky of a change in tone is involved in the heat
treatment after the imparting of curl. When the content of the
surface-active agent is 20% or less, the effect of improving the
texture after the imparting of curl is hardly to be observed.
[0078] In the process shown in FIG. 12, the aluminum pipe member 33
of a circular sectional configuration is placed at one end of the
sheet material 35, and they are wound integrally around the pipe
member 33 while applying tension to the weft 14 and the sheet
material 35, fixing the outside center and both side ends of the
tuft 14 in position by the fixing means 36, such as an adhesive
tape or a rubber band, as shown in FIGS. 13 and 14. Next, the pipe
member 33 around which the weft 14 and the sheet material 35 have
been wound is put in a dryer set at a temperature of approximately
90.degree. C., and heat treatment is conducted for approximately
one hour. After that, the pipe member 33 is extracted and allowed
to cool itself. Finally, the weft 14 is removed from the sheet
material 35.
[0079] Next, the fifth embodiment of the present invention will be
described with reference FIGS. 7 through 16 common to the third and
fourth embodiments plus FIGS. 17 and 18. A detailed description of
the components that are the same as those of the third and fourth
embodiments will be omitted. This embodiment is superior in
imparting curl to the hair pieces 10a, 10b of a hair material 10
that is formed of polyamide, in particular, a straight-chain
aliphatic polyamide. Further, it is more desirable that the
coloring of the hair material be effected by mixing in the raw
material, that the surface of the hair material be composed of
spherulites, blasts or a combination thereof to form asperities 10e
on the surface of the artificial hair material 10 to thereby
suppress the gloss thereof, and that the shrinkage rate of the hair
material be 2 to 5%.
[0080] In the fifth embodiment, the processes of FIGS. 7 and 8 are
the same as those of the third and fourth embodiments. When they
are wound around the pipe member 33, the weft 14 and the sheet
material 35 are immersed in an aqueous solution of silicon
emulsion. As the sheet material 35, a non-woven fabric of a weight
per unit area [metuske] of 18 to 30 g/m.sup.2 is suitably used.
When the weight per unit area [metuske] is 18 g/m.sup.2 or less,
the impregnation amount of the silicon emulsion aqueous solution is
small, and it is rather difficult to fix the skin on the surface of
the hair material uniformly and at a predetermined film pressure.
The sheet material is likely to suffer damage when tension is
applied thereto while winding it around the pipe member 33. On the
other hand, when the weight per unit area [metuske] is 30 g/m.sup.2
or more, the thickness of the sheet material 35 increases, so that
when it is wound around the pipe member 33, its diameter increases
as the winding diameter increases, with the result that the weft 14
is likely to assume loose curl, which is weaker than curl of a
predetermined configuration.
[0081] As the non-woven fabric for the sheet material 35, it is
desirable to adopt one that increases in surface friction force
when moistened to thereby prevent slippage. If the surface of the
sheet material 35 is slippery when moistened, spinning occurs when
it is wound around the aluminum pipe member 33, and a gap is
generated between the pipe member 33 and the weft 14 wound around
it, which leads to loose curl. For these reasons, the material of
the non-woven fabric is preferably rayon or polyester, as described
above, with the weight per unit area [metuske] thereof being
preferably 18 to 30 g/m.sup.2.
[0082] The silicon emulsion is used for the purpose of imparting
curl to the hair material 10 and imparting smoothness and a deep
color effect to the hair material surface. From the viewpoint of
deep color effect, texture, and durability, an anionic discoloring
epoxy silicon is preferable, and an aqueous solution concentration
of 1 to 2% is preferable since it involves no discoloration or
sticky texture after the imparting of curl.
[0083] In the process of FIGS. 9 and 11(a) subsequent to FIGS. 7
and 8, the weft 14 and the sheet material 35 are immersed in an
aqueous solution of silicon emulsion and are then lightly squeezed.
FIG. 9 shows how the sheet material 35 is spread over the working
table so as to involve no wrinkles, with the weft 14 being placed
at a predetermined position on the sheet material 35. Next, the
weft 14 is combed so as to make it straight. As a result, as shown
in FIGS. 10 and 11(b), the hair materials 10 are aligned in a row
so as to involve no gap therebetween, thereby reducing the
thickness of the weft 14.
[0084] In the next process shown in FIG. 12, the aluminum pipe
member 33 with a circular sectional configuration is placed at one
end of the sheet material 35, and the weft 14 and the sheet
material 35 are integrally wound around the pipe member 33 while
applying tension thereto, fixing the outside center and both side
ends of the weft 14 in position by the fixing means 36, such as an
adhesive tape or a rubber band, as shown in FIGS. 13 and 14. Next,
the pipe member 33 around which the weft 14 and the sheet material
35 are wound is covered with a towel or the like to wipe away
surplus silicon emulsion aqueous solution.
[0085] In the next process shown in FIG. 18, the outer side of the
weft 14, the sheet material 35, and the pipe member 33 as a whole
is covered with an aluminum foil 37, and is put in a dryer set at a
temperature of 160 to 170.degree. C. to conduct heat treatment for
40 to 60 minutes.
[0086] After the heat treatment, the whole is extracted from the
dryer, and allowed to cool itself. Finally, the weft 14 is
extracted.
[0087] The covering with the aluminum foil 37 in this embodiment is
effected for the purpose of obtaining a curl of high retaining
property at lower temperature by continuously applying moist air
and dry air in a single heat treatment. That is, for 20 to 30
minutes after the whole is put in the dryer, the evaporation of the
water of the silicon emulsion aqueous solution with which the weft
14 and the sheet material 35 are impregnated is suppressed by the
influence of the materials of the aluminum pipe member 33 and the
aluminum foil 37, so that the weft 14 is subjected to heat
treatment at high temperature and high humidity. When, thereafter,
the water has been evaporated, the heat treatment is conducted in a
dry state.
[0088] In this way, in the fifth embodiment, it is possible to
apply moist air and dry air continuously with ease, without using
any special device, through a combination of the material and
weight per unit area [metuske] of the non-woven fabric wound
together with the weft 14, the aluminum pipe member 33, and the
aluminum foil 37, and through adjustment of the temperature and
time of the heat treatment, thereby making it possible to obtain a
curl of still higher retaining property.
[0089] Next, the sixth embodiment of the present invention will be
described with reference FIGS. 7 through 16 common to the third
through fifth embodiments plus FIGS. 19 and 20. A detailed
description of the components that are the same as those of the
third through fifth embodiments will be omitted. This embodiment is
suitable for an artificial hair described below. That is, an
artificial hair of a core/sheath structure is preferable, with the
core portion being formed of a semi-aromatic polyamide with a
phenylene unit in the main chain, and the sheath portion being
formed of a straight-chain aliphatic polyamide of methylene chain
bonding. The sheath/core weight ratio ranges from 30/70 to 10/90,
and the hair thickness ranges from 40 to 80 .mu.m.
[0090] As the semi-aromatic polyamide forming the core portion, it
is more desirable to adopt, for example, nylon MXD6, which is
obtained through polymerization of methaxylenediamine and adipic
acid. As the straight-chain aliphatic polyamide forming the sheath
portion, it is more desirable to adopt, for example, nylon 6. FIG.
19 is a schematic sectional view of the artificial hair material of
the sheath/core structure. Further, as shown in FIG. 20(a), the
surface of the artificial hair material 10 is preferably roughened
by blast shot or the like to form asperities 10f to thereby
suppress gloss. As shown in FIG. 20(b), which is an enlarged view,
the asperities 10f are preferably formed to such a degree that the
maximum difference in height between the protrusions and recesses,
indicated at 38, is approximately 1.3 .mu.m.
[0091] In the sixth embodiment, the processes of FIGS. 7 and 8 are
the same as those of the fifth embodiment. As in the fifth
embodiment, when winding the weft 14 and the sheet material 35
around the pipe member 33, they are immersed in an aqueous solution
of silicon emulsion. Apart from imparting curl, this aqueous
solution of silicon emulsion is used for the purpose of fixing a
film with smoothness to the surface of the hair materials 10. As
the sheet material 35, a non-woven fabric of rayon or polyester of
a weight per unit area [metuske] of 18 to 30 g/m.sup.2 is
preferable.
[0092] When the weight per unit area [metuske] is 18 g/m.sup.2 or
less, the impregnation amount of the silicon emulsion aqueous
solution is small, and it is rather difficult to fix the skin on
the surface of the hair material uniformly and at a predetermined
film pressure. The sheet material is likely to suffer damage when
tension is applied thereto while winding it around the pipe member
33. On the other hand, when the weight per unit area [metuske] is
30 g/m.sup.2 or more, the thickness of the sheet material 35
increases, so that when it is wound around the pipe member 33, its
diameter increases as the winding diameter increases, with the
result that the weft 14 is likely to assume loose curl, which is
weaker than curl of a predetermined configuration.
[0093] As the non-woven fabric for the sheet material 35, it is
desirable to adopt one that increases in surface friction force
when moistened to thereby prevent slippage. If the surface of the
sheet material 35 is slippery when moistened, spinning occurs when
it is wound around the aluminum pipe member 33, and a gap is
generated between the pipe member 33 and the weft 14 wound around
it, which leads to loose curl. For these reasons, the material of
the non-woven fabric is preferably rayon or polyester, in addition,
with the weight per unit area [metuske] thereof being preferably 18
to 30 g/m.sup.2.
[0094] In the process of FIGS. 9 and 11(a) subsequent to FIGS. 7
and 8, the weft 14 and the sheet material 35 are immersed in an
aqueous solution of silicon emulsion and are then lightly squeezed.
FIG. 9 shows how the sheet material 35 is spread over the working
table so as to involve no wrinkles, with the weft 14 being placed
at a predetermined position on the sheet material 35. Next, the
weft 14 is combed so as to make it straight. As a result, as shown
in FIGS. 10 and 11(b), the hair materials 10 are aligned in a row
so as to involve no gap therebetween, thereby reducing the
thickness of the weft 14.
[0095] In the next process shown in FIG. 12, the aluminum pipe
member 33 with a circular sectional configuration is placed at one
end of the sheet material 35, and the weft 14 and the sheet
material 35 are integrally wound around the pipe member 33 while
applying tension thereto, fixing the outside center and both side
ends of the weft 14 in position by the fixing means 36, such as an
adhesive tape or a rubber band, as shown in FIGS. 13 and 14. Next,
the pipe member 33 around which the weft 14 and the sheet material
35 are wound is covered with a towel or the like to wipe away
surplus silicon emulsion aqueous solution.
[0096] Next, the pipe member 33 around which the weft 14 and the
sheet material 35 are wound is put in a dryer set at a temperature
of 100.degree. C. or less, and dried to evaporate the water
therein, solely leaving silicon on the weft 14 and the sheet
material 35. After that, the pipe member 33 around which the weft
14 and the sheet material 35 are wound is put in a dryer set at a
temperature of 180.degree. C., and heat treatment is conducted for
two hours, thereby imparting curl to the hair materials 10 and
fixing a coating film to the surface of the hair materials 10.
After the heat treatment, the whole is extracted from the dryer,
and allowed to cool itself. Finally, the weft 14 is extracted.
[0097] As a modification of the sixth embodiment described above,
it is also possible to carry out the seventh embodiment described
below. In the seventh embodiment, in the process of the sixth
embodiment shown in FIG. 14, the weft 14 and the sheet material 35
are wound around the pipe member 33, and in the process shown in
FIG. 15, the entire pipe member 33 is covered with the aluminum
foil 37. This is put in a dryer set at a temperature of 180.degree.
C., and heat treatment is conducted for two hours, thereby
imparting curl to the hair materials 10, and at the same time,
fixing a coating film to the surface of the hair materials 10.
After the heat treatment, the whole is extracted from the dryer,
and allowed to cool itself. Finally, the weft 14 is extracted.
