Description

  The present invention relates to a wig having a matte wig base that can be used for a thin wig or a hair removal part of the head and is difficult to visually recognize from the outside, and a method for manufacturing the wig.

  Generally, a wig is composed of a wig base and hair made of human hair or artificial hair implanted in the wig base. As the wig base, those mainly composed of a net member excellent in breathability, and those made of artificial skin mainly molded with a soft synthetic resin, for example, a urethane resin, are known. Since the latter wig base made of artificial skin can exhibit the same skin feeling as the scalp on the appearance, it is particularly suitable for parts that are easily visible from the outside, such as the hairline, the hair-dividing part or the nail part, etc. In addition to the case where the entire wig base is formed with artificial skin, the wig base is frequently used in the case where only the hairline of the net wig base, the hair-cutting part, or the nail part is made artificial skin.

  When hair is attached to a wig base made of artificial skin, so-called V-shaped planting (V planting), in which only hair is inserted through the wig base, is used in order to make hair appear to grow from the scalp. V-type planting is performed by penetrating the hair folded in half using a planting tool such as an acupuncture needle from the front side to the back side, creating a needle foot of about 1 mm, and then bringing one of the folded hair back to the surface. It is planted in a V shape by pulling it out to the side. However, if the hair is simply planted in a V shape, the hair can be easily pulled out by fingers or brushing, so that a hair fixing process for fixing the hair becomes indispensable. In order to fix the hair, usually, after the planting, a solvent for adhesion diluted with an organic solvent is applied from the back of the wig base, and this solvent is attached to the artificial skin and solidified to solidify the hair. The part is sandwiched between the artificial skin and the adhesive coating and held in a fixed manner (see Patent Documents 1 and 2).

Further, even with a wig made of artificial skin, light may be reflected by the artificial skin base through a gap between the implanted hairs, and an unnatural luster different from the scalp color may appear. If the surface of the wig base is glossy, it may be easily recognized that the wig is mounted. Therefore, it is desirable to apply a matte process that suppresses unnatural gloss. The matte processing is performed by physically roughening the surface of the artificial skin base formed of synthetic resin material by sandblasting or embossing, or by mixing foreign substances such as inorganic substances into the synthetic resin. There is a known technique for suppressing the gloss by irregularly reflecting the reflected light.
Sand blasting and embossing are suitable for processing flat materials in the form of sheets or films using machines, but are not suitable for processing bulging wig bases with head shapes. . The method of mixing foreign substances such as inorganic substances is simple and suitable for the production of wigs, but it is difficult to control the natural luster by shining alone, and inorganic substances are mixed in soft synthetic resin materials. For this reason, the wig base becomes hard and it is difficult to follow the movement of the user's head shape and scalp.

Further, as a matte process for a wig base having a head shape, Patent Documents 3 and 4 disclose a method of randomly eroding the surface of a wig base member to impart fine irregularities to roughen the surface. ing.
JP-A-52-123755 (Claims) Japanese Patent No. 3484565 JP-A-2-216207 Japanese Patent Laid-Open No. 3-69601

  In this way, in conventional matte processing to reduce the gloss of the surface of the wig base, there are methods of physically roughing the surface by sandblasting or embossing, etc., and methods of suppressing gloss by mixing foreign substances such as inorganic substances It is difficult to control the natural luster by delustering it to an appropriate degree and giving it the same luster and skin feel as a human scalp.

  In particular, the method of mixing foreign substances such as inorganic substances into a synthetic resin material that is a base for artificial skin is inconspicuous up to a certain mixing ratio, but the color of inorganic substances is not noticeable up to a certain mixing ratio. The base itself becomes unnatural, and the molded artificial skin base becomes hard, and when it is attached to the scalp, it cannot follow the movement of the skin and the adhesion with the scalp is reduced. The method of using and bonding the wig base to the scalp is disadvantageous in that it easily peels.

  In view of the above problems, the present invention has a high matte effect even in the case of an artificial skin wig base that is thinly formed of a soft synthetic resin material, and has a gloss and skin feel of a human scalp. Therefore, it is difficult to visually recognize that it is a wig base from the outside, and in the case of a method of bonding the wig base to the scalp using an adhesive, it follows the movement of the scalp and has good adhesion to the scalp and peels off. It is an object of the present invention to provide a wig having a matte wig base and a method for producing the same.

In order to achieve the above-mentioned object, the wig of the present invention comprises a head-shaped artificial skin base in which at least a part of a wig base is made of a soft synthetic resin, for example, a thin sheet of urethane resin. The skin base is characterized in that a matting agent is mixed and a matte treatment is performed by forming fine irregularities on the surface.
In the above configuration, the matting agent is an inorganic particle, and preferably, the matting agent is exposed to the surface of the fine irregularities on the surface of the artificial skin base and is added from the surface side to a predetermined depth, so that the back surface of the artificial skin base is used. That is, the matting agent does not reach the inner surface that is in close contact with the scalp when worn. Furthermore, the surface of the artificial skin base has fine irregularities formed by transfer with fine mesh fibers. The artificial skin base is formed into a thin sheet with, for example, urethane resin.
Further, in the wig of another configuration of the present invention, at least a part of the wig base is made of an artificial skin base made of a soft synthetic resin, and the artificial skin base includes a base layer that does not contain a matting agent, and a base layer on the base layer. It consists of two layers with an upper layer mixed with a layered matting agent, and is characterized in that it is matted by forming fine irregularities on the surface of the upper layer.

  According to the above configuration, a matting agent is added to the artificial skin base, and the surface is matte by the fine irregularities, so that the scalp feels matte to the same degree as the human head. In addition to the presence of a matting agent and surface irregularities even when external light is incident on the artificial skin base through the gaps between the hairs, and the fine irregularities exhibit a wrinkle pattern on the skin. Thus, it is possible to realize a wig in which light is irregularly reflected and the presence of the wig base is hardly exposed. Furthermore, when a matting agent is added from the surface of the artificial skin base to a predetermined depth, that is, it is blended only on the surface side of the artificial skin, and on the back side, that is, on the inner surface side area that is in close contact with the scalp when worn. If the matting agent has not been reached, the matting agent is not blended in the lower side in contact with the scalp of the artificial skin base, and the soft skin is maintained. When attached to the skin, it can follow the movement of the skin, and can provide a wig with good adhesion to the scalp and difficult to peel off.

The wig production method of the present invention includes a step of matting the artificial skin base when forming the artificial skin base of the soft synthetic resin material constituting at least a part of the wig base. The treatment step is characterized by comprising a step of forming a matte layer by adding a matting agent to a soft synthetic resin material, and a step of forming fine irregularities on the surface.
In the above configuration, the step of forming the artificial skin base preferably includes a step of forming a base layer having a predetermined base shape and a predetermined thickness by applying and drying a synthetic resin material solution, and then a synthetic resin material solution. And a step of forming a matte layer having a predetermined thickness by applying a solution containing inorganic particles to the top surface of the base layer and drying the solution. The matting layer forming step is performed during the artificial skin base forming step by applying and drying a solution obtained by adding inorganic particles to a synthetic resin material solution.
Moreover, the fine uneven | corrugated | grooved part formation process of the artificial skin base is preferably performed by covering the matte layer with a fine mesh-like net member after the matte layer forming process and transferring the fine mesh. More specifically, after the matting layer forming step, the mat member is covered with a fine mesh-shaped net member, further coated with a synthetic resin solvent, dried, and then peeled off. The fine mesh is transferred by slightly dissolving the eraser layer to form an uneven portion.
Furthermore, the step of forming the artificial skin base preferably includes a step of forming a base layer having a predetermined thickness by applying a synthetic resin material solution to a head-shaped male mold so as to have a predetermined base shape and drying. Next, a step of forming a matte layer having a predetermined thickness by applying a solution obtained by adding inorganic particles to a solution of a synthetic resin material on the upper surface of the base layer and drying it.
The artificial skin base is formed into a head-shaped sheet on a head-shaped male mold by, for example, urethane resin.

  According to the above configuration, the artificial skin base is formed in two layers of the base layer not containing the inorganic particles and the matting layer containing the matting agent for the inorganic particles on the upper side, so that the artificial skin base that adheres at least to the scalp is used. The base layer is rich in flexibility, and a wig with good adhesion to the scalp can be obtained when an artificial skin base is applied. In addition, since the surface of the matte layer is matted by forming finer uneven parts, the scalp feels matte to the same degree as the human head, and the fine irregularities are the skin wrinkles. Even if external light is incident on the artificial skin base through the gaps in the hair, the light is diffusely reflected due to the presence of the matting agent and fine irregularities on the surface, and the presence of the wig base. Is difficult to see.

  According to the wig of the present invention and the method of manufacturing the wig, the matte agent is added to the artificial skin base, and the surface is mattely processed by fine irregularities, so that the heel is also comparable to a human head. The matte scalp feels like a human, and the fine unevenness gives the skin's wrinkle pattern and the same skin feel as a human being. Even if external light enters the artificial skin base through the gaps in the hair, the matting agent Because of the presence of fine irregularities on the surface, light is irregularly reflected, and it is possible to realize a wig that is difficult to visually recognize as a wig base using artificial skin. Furthermore, when the artificial skin base is attached to the scalp with an adhesive, it is possible to manufacture a wig that follows the movement of the skin and has good adhesion to the scalp and is difficult to peel off.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a cross-sectional view schematically showing the structure of a wig 1 having a wig base 2 that has been matted according to the present invention, and FIG. 2 is a surface side of the wig 1 of FIG. 1, that is, a direction in which hair 3 extends upward. FIG. As shown in the figure, the wig 1 is basically composed of a wig base 2 that has been matted, and hair 3 that is implanted in the wig base 2.
The matte treatment of the wig base 2 includes forming a matte layer on the wig base by adding a matting agent 4 into the wig base 2, and extending the surface of the wig base, that is, the implanted hair. It consists of forming the fine uneven part 20 in the surface of the side visually recognized from the outside. The fine concavo-convex portion 20 includes a concave portion 20a and a convex portion 20b. Further, in the illustrated case, the matting agent 4 is added from the surface side of the wig base 2 to the depth of the predetermined region 21 without being mixed with the entire wig base 2.
Furthermore, the wig base 2 of the present invention may be provided with an adhesive layer 5 for fixing the planted hair 3 to the wig base 2 on the back surface (inner surface) side, as will be described later.

  Here, the matted wig base 2 is formed of an artificial skin member. Hereinafter, a wig base made of an artificial skin member is referred to as an artificial skin base. In the present invention, the entire wig base may be made of an artificial skin member, or only a part of the wig base formed mainly of a net member, for example, the forehead, the top of the head, or the hair part. It may be formed using an artificial skin base. The material of this artificial skin member can be thinly molded with a soft synthetic resin such as urethane resin or silicon resin. A soft synthetic resin such as urethane resin or silicone resin has a certain degree of elasticity and stretchability, and therefore has a good fit when attached in close contact with the scalp.

  When the thickness of the artificial skin base 2 is reduced to reduce the weight, the matting agent 4 is added to the artificial skin in consideration of the matting effect and the ability to follow the movement of the skin when attached to the scalp. It is preferable to add the depth from the surface of the base 2 as shallow as possible. As an example, when the thickness of the artificial skin base 2 is set to about 0.05 to 0.1 mm, the matting agent 4 is removed from the surface side of the artificial skin base 2 to a depth of about 0.01 to 0.02 mm. It is sufficient to add more. If it is shallower than 0.01 mm, the matting agent itself has a conspicuous color and the matting effect is not sufficient. If it is thicker than about 0.02 mm, the gloss of the surface of the artificial skin base 2 does not disappear and further hardens. It becomes difficult to follow the movement, which is not preferable.

  FIG. 3 is a cross-sectional view schematically showing a modification of the configuration of the wig of the present invention. The wig 10 of the present invention comprises an artificial skin base 2 formed of two layers of a base layer 2a that does not contain the matting agent 4 and an upper layer 2b that is a mixture of the matting agent 4 laminated on the base layer 2a. A matte treatment is performed by forming fine irregularities 2c (see FIG. 2) on the surface of the substrate. Since the other structure is the same as the wig 1 shown in FIG. 1, description is abbreviate | omitted. Now, when the total thickness of the artificial skin base 2 is set to about 0.05 to 0.1 mm, the base layer 2a has a thickness of about 0.04 to 0.08 mm, and the upper layer 2b to which the matting agent 4 is added. Is set to a thickness of about 0.01 to 0.02 mm, it is possible to exhibit good follow-up to the scalp by the flexible base layer 2a as well as a good matting effect.

  As the matting agent 4, various inorganic particles can be used. As the material of the inorganic particles 4, any of silica, titanium oxide, aluminum oxide, aluminum hydroxide, magnesium carbonate, calcium carbonate, zeolite, and glass can be used. In particular, powdered silica having a particle diameter of 1 to 10 μm is suitable. At this time, the powdered silica is desirably 5 to 25% based on the weight of the thermoplastic elastomer dissolved in an appropriate organic solvent to be applied. As a matting agent 4, for example, by using an appropriate amount of powdered silica, the color of the scalp of the adherend can be seen through without showing the color of the silica itself. The border is less visible and the naturalness of wearing the wig is improved.

  Although the detailed uneven | corrugated | grooved part 20 is explained in full detail later, it can be formed by transcription | transfer using fine mesh fibers, such as a net-like textile fabric. Fine mesh pattern irregularities are formed on the surface of the artificial skin base 2 by transferring the mesh pattern by pressing the vertical and horizontal fine lattice-like filaments constituting the net member against the artificial skin base 2. . This fine uneven part exhibits a pattern simulating the skin.

  The hair 3 implanted in the artificial skin base 2 is made of human hair or artificial hair. As shown in the figure, the hair 3 is implanted through the matte-treated artificial skin base 2 from the front side to the back side, and is pulled out again to the front side of the artificial skin base 2 to form a V-shape or U-shape. Can be planted in a shape. The hair portion that penetrates the back surface of the artificial skin base 2 and is exposed on the back surface side is referred to as a needle foot portion 3A. Such a planting method is generally referred to as V planting.

  By the way, the hair 3 planted on the artificial skin base 2 by the V planting technique is simply planted in a V shape by pulling out the hair 3 again from the front side to the back side of the artificial skin base 2 to the front side. Therefore, in order to securely fix the planted hair 3, an adhesive solution diluted with an organic solvent is applied from the back surface of the matte artificial skin base 2 after planting, It is necessary to form a so-called adhesive layer 5 by adhering this solution to the skin and solidifying it. Thereby, the needle foot part 3A of the V-planted hair can be securely held by being sandwiched between the artificial skin and the adhesive coating film.

  FIG. 4 is a cross-sectional view schematically showing another modification of the configuration of the wig of the present invention. As shown in FIG. 4, the wig 15 of the present invention is attached to the scalp on the adhesive layer 5 to which the hair 3 of the wig 1 shown in FIG. 1 is fixed, that is, on the lowermost surface side of the wig 1. The adhesive layer 6 is provided. Since the other structure is the same as that of the wig 1, the description thereof is omitted. For example, a double-sided tape can be used as the adhesive layer 6, and when the user wears a wig, the protective layer or protective tape of the double-sided tape is peeled off, and the adhesive layer is attached to the scalp. can do. The adhesive layer 6 for adhering to the scalp may be applied to the wig 10 shown in FIG.

  In the wigs 1, 10 and 15 of the present invention, the matte artificial skin base 2 may be used for the entire wig base, or the artificial skin base 2 is provided on a part of the wig base. There may be. Therefore, it is only necessary to design the size and design of the wig as appropriate according to the hair loss or thinning state of the adherend, and to apply a matte treatment only to the portion using the artificial skin base.

Thus, according to the wigs 1, 10, and 15 having the matted wig base 2 of the present invention, the composite gloss is caused by the irregular reflection of the incident light from the outside by the matting agent 4 and the fine irregularities 20. Erasing effect is demonstrated. Since the color of the powdered silica itself is inconspicuous and the color of the scalp of the wearer can be seen through, the boundary between the wig base and the scalp becomes difficult to be visually recognized, and the naturalness of the wig is improved.
Furthermore, in the case where the inorganic substance is added to the whole artificial skin base 2 and mixed, even if a desired gloss is obtained, the artificial skin base 2 becomes hard and has a poor feeling when worn on the head. However, it was difficult to approximate the color of the matte wig base 2 due to the action of the added inorganic substance and approximate the color of the scalp of the wearer. Therefore, such a drawback can be solved by adopting a structure in which a matting agent is introduced only in a certain depth region. Thereby, according to this invention, the wig 1,10,15 which has the wig base 2 by which the movement of the scalp was easy to follow and the mat | matte process of the matt effect was very high is realizable.

Next, the manufacturing method of the wig by this invention is demonstrated.
The wigs 1, 10 and 15 of the present invention include a step of matting the artificial skin base 2 when forming the artificial skin base 2, and the matting processing step is performed on the soft synthetic resin material and the matting agent 4. Can be produced by the step of forming a matte layer by adding, and the step of forming fine irregularities 20 on the surface of the matte layer.
You may perform the formation process of a mat layer in the formation process of the artificial skin base 2 by apply | coating and drying the solution which added the inorganic particle to the solution of the synthetic resin material. The matte layer forming step includes applying a synthetic resin material solution and drying to form a base layer 2a having a predetermined base shape and a predetermined thickness, and then adding inorganic particles to the synthetic resin material solution. You may perform by the process of forming the matte layer 2b of predetermined thickness by apply | coating the solution which carried out to the upper surface of the base layer 2a, and drying. The artificial skin base 2 may be formed into a head-shaped sheet with urethane resin. In particular, when a head-shaped male mold is used to form a head-shaped sheet, a wig having an excellent fit can be obtained.

  After forming the matte layer, the step of forming the fine irregularities 20 on the artificial skin base 2 can be performed by covering the matte layer with a fine mesh net member and transferring the fine mesh. For example, after the matting layer forming step, by covering the matting layer with a fine mesh net member, applying a synthetic resin solvent, drying it to some extent, and peeling the net member, A fine mesh can be transferred.

Next, the specific manufacturing method of the wig 1 by this invention is demonstrated.
As the first step, the wig base for planting the hair 3 before matting treatment is a solution in which a thermoplastic elastomer made of a soft synthetic resin is appropriately dissolved in an organic solvent (hereinafter referred to as a thermoplastic elastomer solution as appropriate). ) Is applied to a previously prepared wig-attached head-shaped male mold (for example, a plaster mold), and then dried to form an artificial skin resembling a human scalp. In addition, in order to improve the strength of the artificial skin, the above-mentioned thermoplastic elastomer solution is applied on a wig-attached head-shaped male mold with a fine mesh fiber or net, and then dried. Alternatively, it may be formed on artificial skin mixed with knitted fabric such as fine mesh fiber or net. Various thermoplastic elastomers can be applied, and for example, urethane elastomer is preferable. Moreover, you may add an antifungal agent etc. as needed. At this time, the size of the wig may be determined according to the head state of the adherend, and may be a so-called partial wig or a wig that covers the entire head. When the artificial skin is used in a flat portion of the user's head, it may be formed into a sheet shape.

As the second step, the wig base molded in the first step can be matted in the following steps to give a natural matte gloss to the surface of the wig base 2.
Specifically, a solution obtained by adding inorganic particles as the matting agent 4 to the thermoplastic elastomer solution used in the preparation of the wig base is applied and then dried. When the thickness of the wig base is about 0.05 to 0.1 mm, the depth of the region 21 containing the matting agent 4 when this solution is applied and dried is about 0.01 to 0.015 mm. Is preferred. For this purpose, the viscosity of the thermoplastic elastomer in the solution to be applied may be adjusted. Various inorganic particles can be applied, but powdered silica having a particle diameter of 1 to 10 μm is preferable, and the addition amount is desirably 5 to 25% with respect to the weight of the thermoplastic elastomer dissolved in the solution to be applied. .
Moreover, you may add the ultraviolet absorber for the deterioration prevention of a wig base, the oxidizing agent for yellowing prevention, etc. with the matting agent 4 as needed.

As the third step, the wig base with the matting agent 4 added to the surface in the second step is covered with a fine mesh fiber net, the solvent of the wig base material is applied, and after drying, the net is removed to cover the wig base. The wig base portion in contact with the fibers constituting the net is dissolved, and fine concavo-convex portions 20 are formed on the surface of the wig base with fine mesh fibers.
The fine mesh fibrous net used in this step may be any material that does not dissolve in the solvent applied to the wig base. For example, nylon can be used when the wig base is formed of a urethane resin. Further, the net is knitted with a thread diameter of 0.03 to 0.1 mm, and preferably has a size of about 30 to 100 mesh (lines / inch, 1 inch = 2.54 cm).

  By the second and third steps, the wig base formed in the first step is subjected to a matte treatment, and the matted wig base 2 with a natural gloss can be formed. As a result, the matte wig base 2 is subjected to a composite matting process by forming the matting agent-added region 21 to which inorganic particles are added and the fine irregularities 20.

  As a fourth step, human hair or artificial hair to be the hair 3 is planted on the wig base 2 by V planting or the like.

  As a fifth step, an adhesive layer 5 for fixing the hair 3 to the wig base is formed on the back surface of the wig base 2 in which the hair 3 is implanted. The adhesive layer 5 fixes the hair foot 3 </ b> A on the back surface of the wig base 2 to the wig base 2. The adhesive layer 5 is formed by spraying or applying a wig adhesive using a brush.

  According to the above-described steps, the matted wig base 2 of the present invention can be formed, and the wig 1 having the matted wig base 2 can be manufactured. If the wig 1 is provided with an adhesive layer 6 with the scalp, the wig 15 can be manufactured.

Next, the manufacturing method of the wig 10 by the other aspect of this invention is demonstrated.
In the case of the wig 10, the base layer 2 a not containing the matting agent 4 of the artificial skin base 2 is formed in the first step, and the matting agent 4 is mixed on the base layer 2 a in the second step. By forming 2b, an artificial skin base is formed.
Next, by the third step, the artificial skin base 2 can be formed by matting treatment by forming the fine irregularities 20 on the surface of the upper layer 2b of the artificial skin base. By performing the subsequent steps in the same manner as the fourth and fifth steps of the wig 1, the wig 15 can be manufactured. Here, when the total thickness of the artificial skin base 2 is set to about 0.05 to 0.1 mm, the base layer 2a has a thickness of about 0.04 to 0.08 mm, and the upper layer to which the matting agent 4 is added. If 2b is set to a thickness of about 0.01 to 0.02 mm, good follow-up to the scalp by the flexible base layer 2a can be exhibited with a good matting effect.

As an example, a wig 1 having a matted wig base 2 according to the invention was produced.
As the first step, a urethane elastomer is dissolved in DMF and MEK in a pre-prepared gypsum mold of the wig adherent, and a solution containing an ultraviolet absorber, an antioxidant, and an antifungal agent is applied. A wig base having a thickness of about 0.04 mm was produced by drying at a heating temperature of 60 ° C. for about 1 hour.

  Next, as a second step, a urethane elastomer is dissolved in DMF and MEK, and a powdery silica (average particle size: 3.1 μm to 4.1 μm) that becomes the matting agent 4 is further added to the solution added with the antifungal agent. Then, a matting solution to which an ultraviolet absorber and an antioxidant were added was prepared. The weight of silica was about 15% based on the weight of the urethane elastomer. This matting solution was applied to a wig base and dried at a heating temperature of 60 ° C. for about 2 to 4 hours.

Next, as a third step, the wig base on the surface where the matting agent 4 is added to the surface in the second step is covered with a net for a stocking made of nylon as a fine mesh fibrous net, and the wig The base organic solvents MEK and DMF were applied and dried at 100 ° C. for 4 hours. After drying, the net was removed to form fine irregularities 20 on the wig base surface. At this time, the yarn diameter of the net used was 0.05 mm, and the mesh was about 50 mesh (lines / inch).
Thus, the area | region 21 containing the matting agent 4 and the fine uneven | corrugated | grooved part 20 were formed in the surface of the wig base 2 which consists of urethane resins, and the wig base 2 by which the matting process was carried out was manufactured. The thickness of the wig base 2 is increased by about 0.01 to 0.015 mm of the thickness of the region 21 containing the matting agent 4, and the thickness of the entire wig base 2 is about 0.5 to 0.6 mm. It became thick.

  As a fourth step, artificial hair 3 made of nylon was planted on the wig base 2 by V planting.

As a fifth step, the adhesive layer 5 was formed on the back surface of the wig base 2 on which the hair 3 was implanted. Specifically, the wig base 2 in which the hair 3 was implanted was turned over and attached to the head-shaped male mold of the wig wearer.
Next, as an adhesive for forming the adhesive layer 5 for fixing the hair, an adhesive solution obtained by diluting a urethane elastomer of a different grade from the urethane used in the manufacture of the wig with MEK and DMF, which are wig-based organic solvents. The back of the wig base 2 was brushed and dried. Thus, the adhesive layer 5 having a thickness of about 0.1 mm was formed.

FIG. 5 is a diagram showing a scanning electron microscope (SEM) image of the surface of the wig base 2 that has been matted in the wig 1 according to the embodiment. The electron acceleration voltage is 15 keV, and the magnification is 150 times. As shown in the figure, it can be seen that the surface is not flat but rough due to the matting agent 4. And it turns out that the fine recessed part 20a of the surface of the wig 1 is formed of the two linear parts of the drawing horizontal direction transferred by the net.
As can be seen from FIG. 5, the wig base 2 of the wig 1 of the present invention is matted by the matting agent 4 and the fine irregularities 20 formed on the surface of the wig 1.

  Next, when the wig 1 was attached to the scalp of the examinee with the double-sided tape 6 and the appearance was observed, no reflection of light from the periphery of the wig base 2 was observed. Furthermore, even if another person under test who did not wear the wig 1 was allowed to observe, the use of the wig base 2 did not reveal that the wig 1 was worn, and it was found that the appearance was good.

  Furthermore, the sticking property of the wig 1 on the scalp of the examinee and the followability to the scalp were good, and the adhesive layer 6 did not easily peel off. This is because the entire thickness of the wig base 2 is about 0.05 to 0.06 mm, and the layer containing the matting agent 4 is formed only in the region 21 of about 0.01 to 0.015 mm on the surface. It was revealed that the matte wig base 2 in contact with the scalp did not cure.

  The preferred embodiments of the present invention have been described above, but the present invention is not limited to the embodiments, and can be appropriately changed within the scope of the present invention. For example, the matting agent is not limited to silica and may be other matting agents. Furthermore, the specific numerical values and the like described in the above embodiment can be appropriately changed as necessary.
