DESCRIPTION
WIG BASE, WIG, AND METHOD OF MANUFACTURING WIG BASE
Technical Field
[0001]
The present invention relates to a wig base using a
fabric, a wig obtained by implanting false hair on a wig
base, and a method of manufacturing a wig base.
Background Art
[0002]
For wigs to be worn on the head of a person, a
fabric formed in mesh form is used for many wig bases in
consideration of air permeability and wear comfort. In
order to obtain a more natural appearance, there is known a
wig in which artificial skin made from synthetic resin is
used for a hair parted portion of a wig base or the like.
However, since wigs are usually formed by directly joining
false hair with a filament constituting a mesh of a wig
base, a location for implantation is restricted. This may
cause difficulty in providing a desired amount of hair or
forming a flow of hair for hair whorl, a hair parted
portion, or the like.
[0003]
In order to cope with this, there has been proposed
a wig in which a fabric having a dense mesh in a hair
1

CA 03040822 2019-04-16
parted portion of hair is placed on a fabric having a
coarse mesh and sewn together. (See, for example, Patent
Literature 1).

Summary of Invention
Technical Problem
[0005]
According to the wig described in Patent Literature
1, a sufficient amount of hair can be obtained in the hair
parted portion while air permeability is secured. However,
since the coarse and dense fabrics are placed on top of
each other, a difference in height, distortion, or the like
occurs in a wig base, a gap is generated between a wearer's
head and the wig being worn, and fitting comfort is
impaired. Further, since a process of joining the fabrics
is performed, quality stability and productivity may be
lowered.
[0006]
Therefore, there has also been proposed a wig in
which net structures of different squares are integrally
knitted together on an entire surface (see, for example,
2

CA 03040822 2019-04-16
Patent Literature 2). According to the wig described in
Patent Literature 2, it is possible to obtain an effect
similar to that of the invention described in Patent
Literature 1, and it is also possible to suppress a
difference in height in a wig base.
However, since a complicated process is required
when net structures having different squares are integrally
knitted together on an entire surface, productivity is
extremely lowered.
[0007]
The present invention has been made to solve the
above-mentioned problems, and it is an object of the
present invention to provide a wig base in which a
difference in height at a boundary between regions having
different mesh densities is suppressed, thereby improving
fitting comfort, the wig base capable of being easily
manufactured at low cost, a wig obtained by implanting
false hair on the wig base, and a method of manufacturing
the wig base.
Solution to Problem
[0008]
In order to achieve the above object, a wig base
according to one embodiment of the present invention
includes a base fabric, which is an etched fabric, having a
dense mesh region formed of two or more kinds of fibers
3

CA 03040822 2019-04-16
including a first fiber and a second fiber and a coarse
mesh region in which the first fiber is removed as compared
with the dense mesh region.
[0009]
A wig according to one embodiment of the present
invention obtained by implanting false hair on the wig base.
[0010]
A method of manufacturing a wig base according to
one embodiment of the present invention is a method of
manufacturing the wig base, the method including: a first
step of preparing a fabric formed of two or more kinds of
fibers including a first fiber and a second fiber; a second
step of applying an etching agent that dissolves or
decomposes the first fiber and does not dissolve or
decompose the second fiber to a region of part of the
fabric and heating the fabric if necessary; and a third
step of washing the fabric after the second step to remove
the first fiber having been dissolved or decomposed.
Advantageous Effects of Invention
[0011]
As described above, the present invention can
provide a wig base in which a difference in height at a
boundary between regions having different mesh densities is
suppressed to improve fitting comfort, the wig base capable
of being easily manufactured at low cost, a wig obtained by
4

Description of Embodiments
[0013]
A wig base according to a first embodiment of the
present invention includes a base fabric, which is an
etched fabric, having a dense mesh region formed of two or

1 I
CA 03040822 2019-04-16
* more kinds of fibers including a first fiber and a second
fiber and a coarse mesh region in which the first fiber is
removed as compared with the dense mesh region.
[0014]
In the present embodiment, since the dense mesh
region and the coarse mesh region can be obtained by one
etched fabric, it is possible to suppress a difference in
height at the boundary between the regions having different
mesh densities. Therefore, a misalignment hardly occurs
between a wearer's head and the wig base when the wig is
worn, and excellent fitting comfort is obtained. Further,
by an etching process, it is possible to easily form the
wig base at low cost without a complicated knitting process
or the like.
[0015]
A second embodiment of the present invention
provides the wig base, according to the first embodiment,
in which a knot of a fiber is not included in a boundary
portion between the dense mesh region and the coarse mesh
region.
[0016]
The present embodiment does not have a knot of
fibers, which has conventionally been formed when a hair
parted portion and a mesh portion are sewn, at the boundary
portion between the dense mesh region and the coarse mesh
6

region. Accordingly, a wig using the base fabric does not
cause uncomfortable feeling or discomfort due to a wearer's
head hitting the knot, and a wig excellent in fitting
comfort can be obtained.
[0017]
A third embodiment of the present invention provides
the wig base, according to the first or second embodiment,
in which the dense mesh region is disposed in a hair parted
portion.
[0018]
In the present embodiment, since the dense mesh
region is disposed in the hair parted portion, wearing of a
wig is hardly found out and a more natural appearance can
be obtained.
[0019]
A fourth embodiment of the present invention
provides the wig base, according to any one of the first to
third embodiments, in which the dense mesh region is
disposed in an edge portion of the base fabric.
[0020]
In present embodiment, since the dense mesh region
is disposed in the edge portion of the base fabric, it is
possible to increase the strength of the edge portion of
the base fabric and to provide a wig base excellent in
durability with less deformation.

I

CA 03040822 2019-04-16
[0021]
A fifth embodiment of the present invention provides
the wig base, according to any one of the first to fourth
embodiments, in which at least part of the base fabric is
colored to a color similar to a color of a wearer's scalp.
[0022]
In the present embodiment, since at least part of
the base fabric is colored to a color similar to a color of
a wearer's scalp, the wig base fits the skin, and a natural
appearance that does not cause visual discomfort can be
obtained.
[0023]
A wig according to a six embodiment of the present
invention is obtained by implanting false hair on the wig
base according to any one of the first to fifth embodiments.
[0024]
In the present embodiment, any optional function and
effect described above can be obtained.
[0025]
A method of manufacturing a wig base according to a
seventh embodiment of the present invention is a method of
manufacturing the wig base according to any one of the
first to fifth embodiments, the method including: a first
step of preparing a fabric formed of two or more kinds of
fibers including a first fiber and a second fiber; a second
8

CA 03040822 2019-04-16
step of applying an etching agent that dissolves or
decomposes the first fiber and does not dissolve or
decompose the second fiber to a region of part of the
fabric and heating the fabric if necessary; and a third
step of washing the fabric after the second step to remove
the first fiber having been dissolved or decomposed.
[0026]
In the present embodiment, it is possible to obtain
the dense mesh region and the coarse mesh region with a
simple process by the etching process using the etching
agent without requiring a complicated knitting process or
the like. Accordingly, the wig base can be easily
manufactured at low cost.
[0027]
Next, the wig base, the wig obtained by implanting
false hair on the wig base, and the method of manufacturing
the wig base according to embodiments of the present
invention will be described in detail below with referring
to the drawings.
[0028]
(Description of a wig base according to embodiments of the
present invention)
First, with referring to FIGS. 1 to 3, the wig base
according to some embodiments of the present invention will
be described. FIG. 1 is a plan view showing a wig base
9

1 I
CA 03040822 2019-04-16
. according to one embodiment of the present invention, and
FIGS. 2 and 3 are plan views showing the wig base according
to another embodiment of the present invention.
In all the embodiments shown in FIGS. 1 to 3, a wig
base 2 includes a base fabric 8, which is an etched fabric,
having a dense mesh region 4 formed of two or more kinds of
fibers including a first fiber and a second fiber, and a
coarse mesh region 6 in which the first fiber is removed as
compared with the dense mesh region 4. In FIGS. 1 to 3, a
shape of the mesh is schematically shown.
[0029]
The etched fabric is a fabric formed by an etching
process and also referred to as an etched cloth. In the
etching process, an etching agent is applied to a
predetermined region of a fabric, in which a fiber that is
to be dissolved or decomposed by the etching agent and a
fiber that is not to be dissolved or decomposed by the
etching agent are combined, to remove one of the fibers.
In the present embodiment, the first fiber is a
fiber which is dissolved or decomposed by etching, and the
second fiber is a fiber which is not dissolved or
decomposed by etching. It is noted that the first fiber
may include a plurality of fibers, and the second fiber may
include a plurality of fibers.
[0030]

CA 03040822 2019-04-16
_ Here, FIGS. 4(a) to 4(d) show an example of a fabric
formed into a dense mesh form using the first fiber and the
second fiber. FIG. 4 is a plan view showing a fabric in
which the first fiber and the second fiber are knitted in a
dense mesh form. As is apparent from the drawings, the
first fiber 10 is knitted between coarse meshes made of the
second fiber 12 to form a dense mesh.
By removing the first fiber 10 by applying a etching
agent to a predetermined region of the fabric having such a
dense mesh form, an etched fabric having a dense mesh-like
region and a coarse mesh-like region can be formed. It is
noted that the fabric shown in FIGS. 4(a) to 4(d) is merely
an example, and a fabric in which the first fiber 10 and
the second fiber 12 are knitted in other optional patterns
can be used.
[0031]
In the present embodiment, by applying an etching
agent to (if necessary, by heating) a region corresponding
to the coarse mesh region 6, the first fiber in the applied
region is removed, and the base fabric 8 having the dense
mesh region 4 and the coarse mesh region 6 as shown in FIGS.
1 to 3 is formed.
[0032]
In the etched fabric formed in the above manner,
filaments are hardly scattered in a boundary between a
11
I

CA 03040822 2019-04-16
region of the first fiber applied with the etching agent
and a region not applied with the etching agent, and the
sharpness of the boundary is excellent. Particularly, the
fabric is preferably formed with a structure by which the
fabric is hardly frayed even if some threads melt (or are
decomposed) in the design of a knitting structure and a
weaving structure.
The formed base fabric 8 does not have a knot of
fibers, which has conventionally been formed when a hair
parted portion and a mesh portion are sewn, at the boundary
portion between the dense mesh region 4 and the coarse mesh
region 6. Accordingly, a wig using the base fabric 8 does
not cause uncomfortable feeling or discomfort due to a
wearer's head hitting the knot, and a wig excellent in
fitting comfort can be obtained.
[0033]
In all the embodiments shown in FIGS. 1 to 3, the
dense mesh region 4 is disposed in a hair parted portion.
In the wig base 2, it is possible to bind false hair with a
filament of the coarse mesh region 6, and also to bind
false hair of an amount corresponding to a hairline with a
filament in the dense mesh region 4 in the hair parted
portion. At this time, since the dense mesh region 4 is
disposed in the hair parted portion, wearing of a wig
becomes inconspicuous and a more natural appearance can be
12

CA 03040822 2019-04-16
obtained.
[0034]
Furthermore, it is possible to color the dense mesh
region 4 disposed in the hair parted portion to a color
similar to that of a scalp. In such a case, a more natural
appearance can be obtained. Other than the above, it is
also possible to color the entire base fabric 8 to a color
similar to that of a scalp. In a case where at least part
of the base fabric 8 is colored to a color similar to that
of the scalp of a wearer, the wig base 2 fits the skin, a
natural appearance that does not cause visual discomfort
can be obtained.
[0035]
In the other embodiments shown in FIGS. 2 and 3, the
dense mesh region 4 is disposed not only in a hair parted
portion but also in an edge portion of the base fabric 8.
In this manner, it is possible to increase the strength of
the edge portion of the base fabric, and the wig base 2
with less deformation and excellent durability can be
provided.
[0036]
In another embodiment shown in FIG. 3, a reinforcing
member 20 is further sewn to the edge portion of the base
fabric 8 on which the dense mesh region 4 is disposed. By
an increase in the strength by the reinforcing member 20 in
13
1

CA 03040822 2019-04-16
addition to the increase in the strength by the dense mesh
region 4, the wig base 2 with even less deformation and
excellent durability can be provided.
As the reinforcing member 20, a cloth member having
a denser mesh can be used. Further, the reinforcing member
can be obtained by sewing thick threads, and other optional
members can be used as reinforcing members.
[0037]
In all the embodiments shown in FIGS. 1 to 3, the
wig base for an entire head wig is shown. However, the
present invention is not limited to the embodiments, and
there may be a case of a wig base for a partial wig.
Further, in the embodiments shown in FIGS. 1 to 3, the
dense mesh region 4 is disposed in the hair parted portion
and the edge portion of the base fabric. However, the
present invention is not limited to this, and the dense
mesh region 4 can be placed at other optional positions in
accordance with purposes.
[0038]
As described above, the wig base 2 according to the
embodiment of the present invention includes the base
fabric 8 made from an etched fabric having the dense mesh
region 4 formed of two or more kinds of fibers including
the first fiber 10 and the second fiber 12, and the coarse
mesh region 6 obtained by removing the first fiber 10 from
14

CA 03040822 2019-04-16
the dense mesh region 4.
[0039]
Accordingly, since the dense mesh region 4 and the
coarse mesh region 6 can be obtained by one etched fabric,
it is possible to suppress a difference in height at the
boundary between the regions having different mesh
densities. Therefore, a misalignment hardly occurs between
a wearer's head and the wig base when the wig is worn, and
excellent fitting comfort is obtained. Further, by an
etching process, it is possible to easily form the wig base
at low cost without a complicated knitting process or the
like.
[0040]
<Fabric>
Examples of the fabric used in the present invention
include a knitted fabric and a woven fabric. Examples of
the knitted fabric include weft knitted fabric, such as
plain stitch, rib stitch, pearl stitch, or the like and a
warp knitted fabric, such as tricot stitch, cord stitch,
atlas stitch, or the like. Examples of the woven fabric
include plain weave, twill weave, satin weave, or the like.
However, the fabric is not limited to the above. Among
them, a knitted fabric is preferably used from the
viewpoint of elasticity and emphasis on appropriate see-
through sensation and comfort.

1 I
CA 03040822 2019-04-16
Further, since it is possible to flexibly design a
structure, a composite structure combining two or more
kinds of structures is preferably used.
[0041]
Further, denbigh stitch that allows knitting to be
performed evenly over an entire surface is preferably used,
without limitation, as a structure of the first fiber. The
first fiber can be combined with the second fiber by a
method, such as interknitting, combined weaving, mixed
spinning, intertwisting, or the like. Among them,
combination by interknitting and combined weaving is
preferably used, so that the strength after etching is
improved, and a coarse portion and a dense portion can be
more clearly formed.
Further, as the structure of the second fiber, in
order to enhance durability, the second fiber is preferably
knitted with atlas stitch or two needle stitch of a
knitting structure. Furthermore, combination by
interknitting is preferably used for improving elasticity.
[0042]
Further, preferably the first fiber is 20% to 75% by
weight and the second fiber is 25% to 80% by weight, and
more preferably, the first fiber is 30% to 70% by weight
and the second fiber is preferably 30% to 70% by weight.
Further, if the first fiber is 20% by weight or more,
16
1

CA 03040822 2019-04-16
that is, the second fiber is 80% by weight or less, the
form of the fabric can be secured at the time of etching.
Further, when the first fiber is 75% by weight or
less, that is, the second fiber is 25% by weight or more,
the strength as a wig base material can be easily secured.
[0043]
An aperture ratio in the coarse mesh region 6 is
preferably 20% to 90%, and more preferably 50% to 80%. If
the opening ratio is 90% or less, a hair implanted area
that looks naturally can be secured. Further, if the
opening ratio is 20% or more, sufficient air permeability
can be obtained and the wig can be worn comfortably without
the feeling of stuffiness.
[0044]
<Yarn of the first fiber>
A single fiber fineness of the first fiber is
preferably 1 to 4 decitex, and more preferably 1 to 3
decitex. When the single fiber fineness is 4 decitex or
less, flexibility is sufficiently obtained, and variations
in dissolution or decomposition are reduced. If the single
fiber fineness is 1 decitex or more, sufficient flexibility
is obtained and wearing comfort for a wearer is improved.
[0045]
A total fineness of the first fiber is preferably 11
to 110 decitex, more preferably 33 decitex or less, so that
17

CA 03040822 2019-04-16
sufficient flexibility is obtained, variations in
dissolution or decomposition of the first fiber are reduced,
and also wearing comfort for a wearer is improved. Further,
if the total fineness of the first fiber is 11 decitex or
more, sufficient strength can be obtained, and breakage,
split, or the like at the time of production can be reduced.
[0046]
<Yarn of the second fiber>
A single fiber fineness of the second fiber is
preferably 1 to 9 decitex, and more preferably 1 to 6
decitex. If the single fiber fineness is 6 decitex or less,
sufficient flexibility is obtained and also wearing comfort
for a wearer is improved. Further, if the single fiber
fineness is 1 decitex or more, sufficient strength can be
obtained even in the coarse mesh region 6 which has been
subject to an etching process.
[0047]
Further, the total fineness of the second fiber is
preferably 20 to 100 decitex. When the total fineness of
the second fiber is 100 decitex or less, the second fiber
is thin and lightweight, furthermore flexibility is
sufficiently obtained, and wearing comfort for a wearer is
improved. Further, if the total fineness of the second
fiber is 20 decitex or more, occurrence of thread breakage
due to external stress can be reduced.

<Kinds of the etching agent and the first and second
fibers>
The first fiber is not limited in particular as long
as the first fiber is a fiber that is etched by an etching
process, that is, a fiber that is dissolved or decomposed
by the etching agent. The first fiber can be determined
based on a type of the etching agent to be used.
To give an example, in a case where the etching
agent is an alkaline aqueous solution containing guanidine
weak acid salt, sodium hydroxide, alkali metal hydroxide,
alkaline earth hydroxide, or the like, alkaline soluble
cation dyeable polyester fiber or the like is exemplified
as the first fiber.
In this case, as the second fiber, a nylon-based
fiber, a regular polyester-based fiber, a polyurethane-
based fiber, cotton, a cellulose-based fiber for rayon, and
composite fibers of these can be used.
[0049]
In a case where the etching agent is an acidic
aqueous solution containing phenols, alcohols, aluminum
sulfate, sodium acidic sulfate or the like, a cellulose-
based fiber, such as rayon, Bemberg (registered trademark),
lyocell, cotton, hemp, acetate-based fiber, or the like, a
nylon-based fibers, such as nylon 6, nylon 66, or the like
19

CA 03040822 2019-04-16
is exemplified as the first fiber.
In this case, as the second fiber, a polyester-based
fiber, a polyurethane-based fiber, an animal-based natural
fiber, such as wool and silk, which are fibers other than
the above fibers can be used.
[0050]
When the etching agent is water, a water-soluble
fiber, such as vinylon, is exemplified as the first fiber.
In this case, as the second fiber, a fiber other than a
water-soluble fiber can be used.
[0051]
As a combination of the first fiber, the second
fiber, and the etching agent, a combination, in which the
first fiber is a cation dyeable polyester fiber, the second
fiber is nylon 6 or nylon 66, the etching agent is an
acrylic aqueous solution, is preferably used. According to
such a configuration, even when processing is performed
with an alkaline aqueous solution, strength of the non-
etched second fiber is not lowered, and breakage or the
like in the coarse mesh region 6 can be reduced. Further,
by using a polyester-based fiber and a nylon-based fiber as
fiber types, excellent durability is obtained.

When coloring of a fiber is performed, dyeing with
acid dye and disperse dye, or cationic dye can be performed

' easily. Furthermore, when an alkaline aqueous solution is
used as the etching agent, a guanidine weak acid salt is
preferable from the viewpoint that coarse and dense
formation is easily obtained, and the environment and
safety are excellent. Among them, guanidine carbonate is
particularly preferable from the viewpoint that pH of an
aqueous solution is low, 10 to 13, as compared with other
strong alkali, such as sodium hydroxide, the safety of work
and the device are hardly corroded, there is less influence
on the dye used for coloring the fiber, or the like.
[0053]
It is noted that guanidine carbonate is considered
to decompose a cation dyeable polyester fiber because the
guanidine carbonate is decomposed into urea and ammonia to
be changed to strong alkali in a process of heat treatment
performed after application of the guanidine carbonate.

(Description of a method of manufacturing the wig base
according to the embodiments of the present invention)
Next, with referring to FIG. 5, a method of
manufacturing the wig base according to one embodiment of
the present invention will be described. FIG. 5 is a
flowchart showing the method of manufacturing the wig base
according to one embodiment of the present invention.

In FIG. 5, at first, a fabric formed of two or more
kinds of fibers including the first fiber and the second
fiber is prepared (step Si). In this case, there may be a
case where a desired fabric is manufactured, or a fabric
available on the market can be used. Next, the etching
agent which dissolves or decomposes the first fiber and
does not dissolve or decompose the second fiber is applied
to a region (for example, a hair parted portion) of part of
a fabric, and if necessary, the fabric is heated to
dissolve or decompose the first fiber (step S2).
[0056]
In step S2, for example, the etching agent can be
applied to a region of part of the fabric by an inkjet
method. In the inkjet method, the etching agent can be
applied in a complicated and fine shape. Accordingly, it
is possible to obtain a base fabric having optimum coarse
and dense patterns in accordance with the purposes.
Furthermore, coloring of a fabric can also be carried out
in the same process by using an inkjet method, which can
contribute to simplification of the manufacturing process
and reduction of manufacturing cost.
However, the application of the etching agent is not
limited to the case of using the inkjet method, but it is
also possible to use a screen type or roller type printing
device, such as silk screen.

[0057]
As described above, when the etching agent is a
compound, such as guanidine carbonate, the fabric is heated
for a predetermined period of time in order to decompose
the first fiber in step S2.
[0058]
After step S2, the fabric is washed to remove the
first fiber having been dissolved or decomposed (step S3).
In this manner, the base fabric 8, which is an etched
fabric, having the dense mesh region 4 formed of two or
more kinds of fibers including the first fiber and the
second fiber, and the coarse mesh region 6 in which the
first fiber is removed as compared with the dense mesh
region can be obtained. Through the above steps, the wig
base 2 according to the above embodiment can be
manufactured.
[0059]
As described above, in the present embodiment, it is
possible to obtain the dense mesh region 4 and the coarse
mesh region 6 with a simple process by the etching process
using the etching agent without requiring a complicated
knitting process or the like. Accordingly, the wig base 2
can be easily manufactured at low cost.

, <Wig base>
An example of the wig base manufactured as described
above is shown in FIG. 6. FIG. 6 is a perspective view
(photograph) showing an example of the wig base according
to the present invention. In the example shown in FIG. 6,
the dense mesh region 4 is disposed in a hair parted
portion and an edge portion of the base fabric.
[0061]
<Wig>
A wig can be manufactured by binding false hair with
a filament constituting a mesh of the wig base 2. As the
false hair, human hair can be used, or artificial hair made
from a synthetic fiber can also be used. In order to bind
the false hair with the filament, a known optional binding
method can be employed.
[0062]
FIG. 7 shows an example of a wig 30 in which false
hair 32 is implanted in the wig base 2 shown in FIG. 6 as
described above. FIG. 7 is a plan view (photograph)
showing an example of the wig according to the present
invention.
It goes without saying that the wig according to the
present invention can exhibit the above optional action and
effect.
