Description
TECHNICAL FIELD
[0001] The present invention relates to a method for manufacturing
a fiber fabric having a hard texture.
BACKGROUND ART
[0002] Fiber fabrics made of nylon or polyester are required to
have a silky handle. Accordingly, various attempts have been
conducted for softening fiber fabrics. Methods for softening fiber
fabrics include, for example, a method for reducing a diameter of
each of fibers which make up the fiber fabric. The method for
reducing the diameter of a fiber includes some methods, such as a
method for directly drawing a thin fiber at a spinning stage, and a
method for spinning a conjugate yarn made of nylon yarns and
polyester yarns, followed by dissolving and removing polyester
components using alkali agent. In addition to the above, another
method can be raised in which a swelling agent, such as benzyl
alcohol, for swelling nylon yarns is used to swell the nylon yarns,
so that the conjugate yarn is split (Patent Literature (PTL) 1).
With the aforementioned methods, thin fibers are manufactured and
soft fiber fabrics can be obtained.
[0003] However, consumers' preferences have changed in recent
years, and fiber fabrics having a relatively hard handle have been
desirable. To cope with the above, thick yarns are used for
manufacturing fabrics, or fabrics in high density are manufactured,
in addition, other countermeasures are also taken.

SUMMARY OF INVENTION
Technical Problem
[0004] However, manufacturing thick yarns in particular causes such
problems that an amount of resin used for manufacturing yarns
increases, or production per one lot is not high, resulting in
increase in costs for spinning yarns or manufacturing yarns.
Furthermore, weaving fabrics having high density reduces
productivity, which is not desirable.
[0005] Meanwhile, other measures are taken. For example, a resin
for finishing fabrics hard, such as a melamine resin, is used and
applied to versatile fiber fabrics. However, resins cause a fabric
to have a handle unique to the resin which appears on the fabric.
In addition, the resin may be pealed off from the fabric due to
laundry or abrasion, so that durability of the fabric using resin
is insufficient.
[0006] The present invention is made in view of the above, and aims
to provide a method for manufacturing a fiber fabric. The method
provides a fiber fabric having a hard handle, without using a
particularly thick yarn, without manufacturing a fabric in the high
density which increases loads at stages of composing and organizing
the fabric, or without performing the resin treatment for hard
finishing.
Solution to Problem
[0007] As a result of keen examination for solving the above
problems, inventors have achieved the present invention. The
inventors have found that a fiber fabric having a hard handle can
be obtained by performing treatment on a fabric made of nylon
fibers without including polyester fibers, using a treatment liquid
containing benzyl alcohol which has customarily been used, for
manufacturing a soft fabric, on conjugate fibers made of nylon
fibers and polyester fibers.
[0008] In other words, for solving the above problems, a method for
manufacturing a fiber fabric includes performing treatment on a
fabric mainly including nylon fibers with a treatment liquid
containing benzyl alcohol.
[0009] In the method for manufacturing a fiber fabric according to
the present invention, it is preferable that the treatment with the
treatment liquid is performed so that the fiber fabric has a
bending resistance of 100 mm or higher in at least one of a warp
direction and a weft direction as measured according to a 45-degree
cantilever method specified in JIS L 1096.
[0010] In the method for manufacturing a fiber fabric according to
the present invention, it is preferable that the treatment liquid
contains water and 10 grams or more of the benzyl alcohol per
litter of the treatment liquid.
[0011] In the method for manufacturing a fiber fabric according to
the present invention, if the fabric including the nylon fibers is
in rope form, it is preferable that the treatment with the
treatment liquid is performed at a temperature from 80 degrees
Celsius to 130 degrees Celsius.
[0012] In the method for manufacturing a fiber fabric according to
the present invention, if the fabric including the nylon fibers is
in open width form, it is preferable that the treatment with the
treatment liquid is performed at a temperature from 80 degrees
Celsius to 130 degrees Celsius.
[0013] In the method for manufacturing a fiber fabric according to
the present invention, it is preferable that the fabric made only
of the nylon fibers.
[0014] A fiber fabric according to the present invention can be
obtained by performing treatment on a fabric mainly including nylon
fibers with a treatment liquid containing benzyl alcohol.
[0015] In the fiber fabric according to the present invention, it
is preferable that the fiber fabric resulting from the treatment
with the treatment liquid has a bending resistance of 100 mm or
higher in at least one of a warp direction and a weft direction as
measured according to a 45-degree cantilever method specified in
JIS L 1096.
[0016] In the fiber fabric according to the present invention, it
is preferable that the fabric made only of the nylon fibers.
[0017] The fiber fabric according to the present invention can be
used as a garment. Alternatively, the fiber fabric according to the
present invention can be used as a storage tool.
Advantageous Effects of Invention
[0018] With the method for manufacturing a fiber fabric according
to the present invention, a fiber fabric having a hard handle can
be obtained. The fabric resulting from the method can maintain a
shape thereof without using an interlining or the like, to thereby
enable a fiber product to be obtained which is excellent in design
and suitable for needs.
[0019] Furthermore, in the method for manufacturing a fiber fabric
according to the present invention, yarns having versatile
diameters can be used. The use of such yarns provides a fiber
fabric having a hard handle without specifically weaving or
organizing a woven fabric or a knitted fabric in a high density.
Accordingly, production costs which occur at stages of producing
yarns or woven knitted products can be reduced.
DESCRIPTION OF EMBODIMENTS
[0020] Hereinafter, a method for manufacturing a fiber fabric
according to the present invention is described based on
embodiments.
[0021] According to the present invention, treatment is performed
on a fiber fabric mainly made of nylon fibers using a treatment
liquid containing benzyl alcohol, to thereby obtain a fiber fabric
having a hard handle.
[0022] Well-known nylon fibers may be used for the nylon fibers in
the present invention. For example, nylon 6, nylon 10, nylon 11,
nylon 12, nylon 6.6, nylon 6.10, or copolyamide made of these
nylons may be used. Among them, the nylon 6 and the nylon 6.6 are
preferable in terms of fiber properties, such as dyeability and
strength, and a cost performance.
[0023] The fineness of each of the nylon fibers is not specifically
limited, but ranges from 0.0001 dtex to 500 dtex referred to as a
nano-fiber in terms of fineness of a single fiber. Furthermore, the
nylon fibers may be a monofilament, a multifilament, or a
staple.
[0024] Although the fineness of a yarn (a line of thread) may range
from 0.0001 dtex to 1000 dtex, the fineness is not limited
thereto.
[0025] In view of cost reduction, versatility, and excellent
processability, the nylon fibers are preferable which have a single
fiber with the fineness of 0.1 to 10 dtex and a line of thread with
the fineness of 10 dtex to 500 dtex.
[0026] Furthermore, the nylon fibers may be flat yarns or textured
yarns including false-twisting, twisting, Taslan-processed yarns,
or other processed yarns.
[0027] A fiber fabric made of nylon fibers according to the present
invention is mainly made of nylon fibers. In other words, for the
fiber fabric made of nylon fibers, other fibers may be concurrently
used, such as polyester fibers, in a range without departing from a
purpose of the present invention for obtaining a fiber fabric
having a hard handle. However, the fiber fabric made only of the
nylon fibers without including other fibers, such as polyester
fibers, is preferable in light of obtaining the fiber fabric having
a hard handle.
[0028] It should be noted that the fiber fabric having a hard
handle cannot be obtained by performing treatment on a fabric made
of 50 percent polyester fibers and 50 percent nylon fibers with a
treatment liquid containing benzyl alcohol. This is because that
shrinkage of the nylon fibers and that of the polyester fibers
largely differs upon the treatment with the treatment liquid
containing the benzyl alcohol. In other words, if a fiber fabric
made in combination of nylon fibers and other fibers which
substantially differ from the nylon fibers in the shrinkage and are
used in a large part of the fiber fabric is used, the fiber fabric
with the hard handle cannot be obtained at a low cost, which should
be the effect of the present invention.
[0029] Even if fibers, lines of thread, or woven knitted
organizations, which are used in versatile styles, are used, the
fiber fabric made of the nylon fibers according to the present
invention can have the hard handle.
[0030] Next, the method for manufacturing a fiber fabric according
to the present invention is described in more detail.
[0031] In the present invention, treatment is performed on the
fiber fabric made of the nylon fibers with the treatment liquid
containing the benzyl alcohol. The treatment is preferably
performed using a treatment liquid containing water and 10 grams to
300 grams of the benzyl alcohol per litter of the treatment
liquid.
[0032] If an amount of the benzyl alcohol is less than 10 grams per
litter of the treatment liquid, the fiber fabric having
sufficiently hard handle may not be obtained. For making the handle
of the fiber fabric be hardened, it is preferable that the amount
of the benzyl alcohol is more than or equal to 30 grams per litter
of the treatment liquid. On the other hand, if the amount of the
benzyl alcohol exceeds 300 grams per litter, the fiber fabric is
not hardened so much amount as an increased amount of the benzyl
alcohol. Strength of the nylon fibers, on the contrary, may
decrease. In addition, if the amount of the benzyl alcohol
increases, a duty on effluent processing of the treatment liquid
and the like increases.
[0033] It should be noted that benzyl alcohol which is emulsified
using an emulsifying agent is preferable in view of treatment
stability. To the treatment liquid containing the benzyl alcohol, a
defoaming agent, a softener for treatment in bath, a friction mark
prevention agent, or the like may be added.
[0034] The treatment using the treatment liquid containing the
benzyl alcohol can be performed at a treatment temperature of 60 to
150 degrees Celsius.
[0035] When a relatively plane fiber fabric is required, it is
preferable that the treatment using the treatment liquid containing
the benzyl alcohol is performed under a condition that a fiber
fabric is in an open width state. For the occasion, the treatment
temperature preferably ranges from 80 to 130 degrees Celsius.
[0036] In this case, if the treatment temperature is lower than 80
degrees Celsius, the fiber fabric with a sufficiently hard handle
may not be obtained. On the other hand, depending on types of
nylons, if the treatment temperature exceeds 130 degrees Celsius,
strength of the fiber fabric, such as tear strength or the like,
may decrease. For obtaining the hard handle, the treatment is
performed at a temperature from 90 to 125 degrees Celsius, and more
preferably, over 100 to 120 degrees Celsius.
[0037] Depending on the treatment temperature or concentration of
the benzyl alcohol, treatment time is preferably at a level from 5
to 180 minutes. If the treatment time is less than 5 minutes,
non-uniformity may be caused in a hardened portion, or the fiber
fabric having the sufficient hard handle cannot be obtained. In
contrary, the treatment time over 180 minutes is not preferable for
the productivity.
[0038] Furthermore, the treatment time is preferably from 7 to 120
minutes inclusive, in terms of uniformity of the hard handle,
hardness of the fabric, and the productivity.
[0039] As a processing machine used for obtaining a plane fiber
fabric, an atmospheric pressure jigger, a high pressure jigger can
be raised.
[0040] When a fiber fabric having a bulky texture, a wrinkled
texture, or a relatively intensive concave-convex surface is
required, it is preferable that the treatment using the treatment
liquid containing the benzyl alcohol is performed under a condition
that the fiber fabric is in a rope form state. For the occasion,
the treatment temperature ranges preferably from 80 to 130 degrees
Celsius.
[0041] In this case, if the treatment temperature is lower than 80
degrees Celsius, the fiber fabric with the sufficiently hard handle
may not be obtained. On the other hand, depending on a type of
nylons, if the treatment temperature exceeds 130 degrees Celsius,
the strength of the fiber fabric, such as the tear strength or the
like, may decrease. For obtaining the hard handle, the treatment is
performed at a temperature from 90 to 125 degrees Celsius, and more
preferably, over 100 to 125 degrees Celsius.
[0042] The processing machines used for obtaining the fiber fabric
having a wrinkled texture or a relatively intensive convex-concave
surface include a high-pressure jet dyeing machine or a
high-pressure type wince dyeing machine. It is preferable to use
the jet dyeing machine for the uniformity in hardness.
[0043] The method for manufacturing a fiber fabric according to the
present invention can be applied to a fiber fabric shaped in a
garment, a storage tool, or the like.
[0044] For example, when sewn products, such as garments or storage
tools which are prepared using a fabric made of nylon fibers, are
hardened, treatment may be performed with the treatment liquid
containing the benzyl alcohol, using a washer (a drum type
processing machine), at a temperature from 80 to 130 degrees
Celsius for 5 to 180 minutes. It is more preferable that the
treatment is performed at a temperature from 90 to 125 degrees
Celsius.
[0045] Heretofore, an embodiment for the method for manufacturing a
fiber fabric according to the present invention is described. Here,
in the present invention, it is preferable to perform soaping on
the fabric made of the nylon fibers after the treatment with the
treatment liquid containing the benzyl alcohol.
[0046] The soaping is washing processing with water, or hot water
at a temperature of 40 to 100 degrees Celsius. Alternatively, the
soaping is processing with a soaping solution prepared by adding,
to water at a normal temperature or hot-water at temperature of 40
to 100 degrees Celsius, caustic soda, an alkaline agent, such as
soda ash or sodium tripolyphosphate, a surfactant, or a chelating
agent.
[0047] The soaping may be performed more than once. In this case,
the first soaping may be performed using the soaping solution to
which the alkaline agent or the surfactant is added, and the second
soaping is performed using only water.
[0048] Furthermore, drying or thermal setting may be performed
after the soaping, as needed. In addition to the above, dyeing
finishing, water repellent finishing, antibacterial finishing,
anti-odor finishing, water-absorption finishing, ultraviolet
screening finishing, or antistatic finishing may be performed.
[0049] It should be noted that these processing including the
dyeing finishing may be performed after sewing or other processing.
Hard finishing may be supplementarily performed using polyester
resin and the like.
[0050] When thermal processing, such as preliminary setting or
finishing setting, is performed on the fabric made of the nylon
fibers which underwent the treatment with the treatment liquid
containing the benzyl alcohol, a temperature of the thermal
processing may be arbitrarily set at a level of 120 to 200 degrees
Celsius in view of a handle, appearance, weight, density, or other
factors of the fiber fabric according to the present invention.
[0051] In the present invention, the fiber fabric having the hard
handle can be manufactured with the aforementioned manufacturing
method.
[0052] It is preferable that the fiber fabric obtained with the
manufacturing method according to the present invention has bending
resistance of 100 mm or higher in at least one of a weft direction
and a warp direction, which is measured under a condition that an
environment at the measurement is set to 20 degrees
Celsius.times.40% RH, pursuant to a 45-degree cantilever method
specified in "JIS L 1096". Furthermore, it is more preferable that
the fiber fabric has the bending resistance of 150 mm or more in at
least one of the weft direction and the warp direction. Still
furthermore, it is preferable that the fiber fabric has the bending
resistance of 100 mm or more both in the weft direction and the
warp direction. It is more preferable that the fiber fabric has the
bending resistance of 150 mm or more both in the weft direction and
the warp direction.
[0053] As described above, the bending resistance of 100 mm or more
provides a harder handle than a case when a traditional hard
finishing is applied, which is preferable for tailoring
presentation.
[0054] If the bending resistance is 100 mm or more, clothing and
goods made by fabrics, which have customarily been manufactured in
combination with an interlining in a separate step can be produced
only using the fiber fabric according to the present invention but
not using interlining. Such clothing and goods can retain shapes
thereof and include a collar, a cuff, headwear, or shoes.
[0055] Furthermore, if the bending resistance is 100 mm or more,
the fiber fabric according to the present invention can be used for
manufacturing bags, or storage tools including a magazine rack, a
storage box, a clothing case, or a pen case. In this case, the bags
or the storage tools such as a storage box which retain their
shapes can be obtained without coating the fiber fabric with a hard
resin, or without combining, with the fiber fabric, interlinings
made of cardboard boxes, plastic plates, woods, metals, or
resins.
[0056] The upper limit of the bending resistance is not
specifically defined. In view of a design or the like of the
clothing and the bags, the fiber fabric having the necessary
bending resistance may be used. According to the measurement
pursuant to a 45-degree cantilever method specified in JIS L 1096,
the upper limit of the bending resistance of the fiber fabric of
the present invention is 150 mm. However, the fiber fabric which
exceeds this upper limit can be used.
[0057] When wrinkles having the hard handle is formed in the fiber
fabric, a measurement sample may be folded at the wrinkles upon
measurement of the bending resistance, and the bending resistance
of less than 100 mm may be measured. To cope with this, the
measurement sample is taken from a portion having less effect on
the measurement of the bending resistance, and the bending
resistance is measured on the portion.
[0058] As described above, the fiber fabric obtained with the
manufacturing method according to the present invention has the
hard handle. When the fiber fabric is used to produce clothing
including a jacket, headwear, and shoes, the clothing, the
headwear, and the shoes having an unprecedented handle, and rough
and vigorous appearance can be obtained. In addition, clothing
which can retain shapes can be obtained without using the
interlining. The fiber fabric having the hard handle, which is
obtained with the manufacturing method according to the present
invention, is used to produce the storage tools including a bag, a
pouch, a magazine rack, a storage box, a clothing case, or a pen
case, to thereby obtain a new storage tool having excellent
shape-retention properties in addition to a fabric handle without
using the interlining.
EXAMPLES
[0059] Hereinafter, a method for manufacturing a fiber fabric
according to the present invention is described more specifically,
based on examples and comparative examples. It should be noted that
the present invention is not limited to these examples. Bending
resistances in below-shown examples and comparative examples were
measured in an atmosphere in which an environment at the
measurement was 20 degrees Celsius.times.40% RH, pursuant to a
45-degree cantilever method specified in JIS L 1096.
Example 1
[0060] First, Example 1 is described. In Example 1, a woven fabric
(twill, 6-nylon was used for warp and weft at 100%, in which the
warp has 78 dtex/34 filament, while the weft has 235 dtex/34
filament. Weaving density is such that a warp density.times.a weft
density=244 yarns/2.54 cm.times.77 yarns/2.54 cm) made from nylon
fibers was used.
[0061] After the woven fabric was scoured, the scoured woven fabric
was soaked in a treatment liquid containing 150 grams of benzyl
alcohol per litter of the treatment liquid, which was prepared by
injecting emulsified dispersion liquid of the benzyl alcohol into
water. A temperature of the treatment liquid was raised from a room
temperature to 98 degrees Celsius taking 40 minutes by using an
atmospheric pressure jigger, and treatment was performed for 40
minutes with maintaining 98 degrees Celsius (open width fabric
state). After that, the fiber fabric was washed with hot water at
80 degrees Celsius twice, as soaping.
[0062] Next, the fabric is dyed black with acid dye using the
atmospheric pressure jigger (95 degrees Celsius for 60 minutes).
Then, the soaping and fixing processing using synthetic tannin were
performed on the fabric. Subsequently, drying, i.e., finishing set,
is performed at 140 degrees Celsius.
[0063] The density of the obtained fiber fabric was such that the
warp density.times.the weft density=270 yarns/2.54 cm.times.88
yarns/2.54 cm.
[0064] Upon measuring the bending resistance, the bending
resistance in a warp direction was 148 mm while that in the weft
direction was 118 mm. Thus, the fiber fabric having the hard handle
was obtained.
[0065] A bag was produced using the obtained fiber fabric. The
produced bag was able to maintain a three-dimensional shape only
with the fiber fabric without using an interlining, and had
excellent appearance.
Comparative Example 1
[0066] Next, Comparative example 1 is described. In Comparative
example 1, a fiber fabric was obtained in the same manner with that
in Example 1 except that the treatment with the treatment liquid
containing the benzyl alcohol was not performed.
[0067] The density of the obtained fiber fabric was such that the
warp density.times.the weft density=250 yarns/2.54 cm.times.79
yarns/2.54 cm.
[0068] Upon measuring the bending resistance, the bending
resistance in a warp direction was 42 mm while that in a weft
direction was 85 mm. Thus, the fiber fabric having a soft handle
was obtained.
[0069] A bag was produced using the obtained fiber fabric. The
produced bag was not able to maintain a three-dimensional shape
thereof without using an interlining.
Example 2
[0070] Next, Example 2 is described. In Example 2, a woven fabric
made of nylon fibers (twill, 6-nylon was used for warp and weft at
100%, in which the warp was 355 dtex/192 filament, while the weft
was 355 dtex/192 filament. The weaving density was such that the
warp density.times.weft density=95 yarns/2.54 cm.times.62
yarns/2.54 cm) was used.
[0071] After the woven fabric was scoured, the scoured woven fabric
was soaked in a treatment liquid containing 60 grams of benzyl
alcohol per litter of a treatment liquid, which was prepared by
injecting emulsified dispersion liquid of the benzyl alcohol into
water. A temperature of the treatment liquid was raised from a room
temperature to 110 degrees Celsius taking 50 minutes using a jet
dyeing machine, and treatment was performed for 40 minutes with
maintaining 110 degrees Celsius (rope form).
[0072] Then, the fabric was washed, as soaping, with hot water to
which soda ash and surfactant were added, at a temperature of 90
degrees Celsius for 10 minutes, followed by being washed only with
water and dried.
[0073] Next, preliminary setting was performed at a temperature of
160 degrees Celsius, and the fabric was dyed yellow with acid dye
(105 degrees Celsius for 30 minutes). Then, fixing processing using
synthetic tannin was performed on the fabric, followed by
performing drying processing at 120 degrees Celsius.
[0074] Next, water repelling processing was performed using 5%
solution of a fluorine-based water repelling agent including
AsahiGuard AG710 (product of ASAHI GLASS CO., Ltd.), followed by
performing finishing setting at 140 degrees Celsius.
[0075] The density of the obtained fiber fabric was such that the
warp density.times.the weft density=116 yarns/2.54 cm.times.85
yarns/2.54 cm.
[0076] Upon measuring the bending resistance, the bending density
in the warp direction was 148 mm, while that of the weft direction
was 117 mm. A fiber fabric having bulky feeling and a hard handle
was obtained.
[0077] In addition, a coat was produced using the obtained fiber
fabric. The produced coat had stiff feeling, and vigorous external
appearance.
Comparative Example 2
[0078] Next, Comparative example 2 is described. In Comparative
example 2, a fiber fabric was obtained in the same manner
(including jet dyeing processing) with that in Example 2 except
that the treatment with the treatment liquid containing the benzyl
alcohol was not performed.
[0079] The density of the obtained fiber fabric was such that the
warp density.times.the weft density=98 yarns/2.54 cm.times.69
yarns/2.54 cm.
[0080] Upon measuring the bending resistance, the bending
resistance in the warp direction is 40 mm while that in the weft
direction is 35 mm. Thus, the fiber fabric having a soft handle was
obtained. In addition, a coat produced with the fiber fabric had a
soft handle and drape. Thus, the coat having a soft appearance was
obtained.
Example 3
[0081] Next, Example 3 is described. In Example 3, a woven fabric
made of nylon fibers (a plain woven fabric, 6-nylon was used for
warp and weft at 100%, in which the warp was 355 dtex/192 filament,
while the weft was 355 dtex/192 filament. The weaving density was
such that the warp density.times.weft density=89 yarns/2.54
cm.times.42 yarns/2.54 cm) was used.
[0082] After the woven fabric was scoured, the scoured woven fabric
was soaked in a treatment liquid containing 50 grams of benzyl
alcohol per litter of the treatment liquid, which was prepared by
injecting emulsified dispersion liquid of the benzyl alcohol into
water. A temperature of the treatment liquid was raised from a room
temperature to 115 degrees Celsius taking 50 minutes using a jet
dyeing machine, and treatment was performed for 10 minutes with
maintaining 115 degrees Celsius (rope form).
[0083] Then, the fabric was washed, as soaping, with hot water to
which soda ash and surfactant were added, at a temperature of 90
degrees Celsius for 10 minutes, followed by being washed only with
water and dried.
[0084] The density of the obtained fiber fabric was such that the
warp density.times.the weft density=109 yarn/2.54 cm.times.59
yarn/2.54 cm.
[0085] Upon measuring the bending resistance, the bending density
in the warp direction was 150 mm or more, while that of the weft
direction was 105 mm or more. A fiber fabric having bulky feeling
and a hard handle was obtained.
[0086] Next, a bag was sewn using the obtained fabric. Then, the
bag was dyed red with an acid dye (at 105 degrees Celsius for 30
minutes), and underwent fixing processing using a synthetic tannin,
followed by being dried at 120 degrees Celsius. The obtained bag
was able to maintain a three-dimensional shape only with the fiber
fabric without using an interlining, and had excellent
appearance.
Comparative Example 3
[0087] Next, Comparative example 3 is described. In Comparative
example 3, a fiber fabric and a bag were obtained in the same
manner with that in Example 3 except that neither the treatment
using the treatment liquid containing the benzyl alcohol nor dyeing
processing after sewing was performed (no processing using a jet
dyeing machine).
[0088] The density of the obtained fiber fabric was such that the
warp density.times.the weft density=96 yarns/2.54 cm.times.45
yarns/2.54 cm.
[0089] Upon measuring the bending resistance, the bending
resistance in the warp direction was 56 mm while that in the weft
direction was 45 mm. Thus, a fiber fabric having a soft handle was
obtained.
[0090] The obtained bag was not able to maintain a
three-dimensional shape thereof without using an interlining.
Example 4
[0091] Next, Example 4 is described. In Example 4, a woven fabric
made from nylon fibers (twill, 6-nyron was used for warp and weft
at 100%, in which the warp was 355 dtex/192 filament, while the
weft was 355 dtex/192 filament. The weaving density was such that
the warp density.times.weft density=91 yarns/2.54 cm.times.62
yarns/2.54 cm) was used.
[0092] After the woven fabric was scoured, the scoured woven fabric
was soaked in a treatment liquid containing 40 grams of benzyl
alcohol per litter of the treatment liquid, which was prepared by
injecting emulsified dispersion liquid of the benzyl alcohol into
water. A temperature of the treatment liquid was raised from a room
temperature to 105 degrees Celsius taking 50 minutes using a jet
dyeing machine, and treatment was performed for 20 minutes with
maintaining 105 degrees Celsius (rope form).
[0093] Then, the fabric was washed, as soaping, with hot water to
which soda ash and surfactant were added, at a temperature of 90
degrees Celsius for 10 minutes, followed by being washed only with
water and dried.
[0094] The density of the obtained fiber fabric was such that the
warp density.times.the weft density=120 yarns/2.54 cm.times.85
yarns/2.54 cm.
[0095] Upon measuring the bending resistance, the bending density
in the warp direction was 150 mm or more, while that of the weft
direction was 116 mm or more. A fiber fabric having bulky feeling
and a hard handle was obtained.
[0096] Next, headwear was sewn using the obtained fabric. Then, the
headwear was dyed navy with an acid dye (at 105 degrees Celsius for
30 minutes), and underwent fixing processing using a synthetic
tannin, followed by being dried at 120 degrees Celsius. The
obtained bag was able to maintain a three-dimensional shape only
with the fiber fabric without using an interlining, and had
excellent appearance.
Comparative Example 4
[0097] Next, Comparative example 4 is described. In Comparative
example 4, a fiber fabric was obtained in the same manner
(including processing using a jet dyeing machine) with that in
Example 4 except that emulsified dispersion liquid containing the
benzyl alcohol was not injected.
[0098] The density of the obtained fiber fabric was such that the
warp density.times.the weft density=102 yarns/2.54 cm.times.72
yarns/2.54 cm.
[0099] Upon measuring the bending resistance, the bending
resistance in the warp direction was 40 mm while that in the weft
direction was 30 mm. Thus, a fiber fabric having a soft handle was
obtained.
[0100] The obtained fiber fabric was used to produce headwear. The
obtained headwear was not able to maintain a three-dimensional
shape thereof without using an interlining.
INDUSTRIAL APPLICABILITY
