[Figure 11] An example of a wig base 10 according to another embodiment is shown. [Modes for carrying out the invention]

[0013] The present invention will be described below through embodiments, but these embodiments are not intended to limit the scope of the claims. Furthermore, not all combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0014] Figure 1 shows an example of a wig base 10 according to this embodiment. The wig base 10 has a shape that conforms to the user's head and is approximately 30 cm square. The wig base 10 becomes a wig 20 when hair 21 is implanted into it. The wig base 10 comprises a peripheral portion 11 and a main body portion 13. The peripheral portion 11 is located on the periphery of the main body portion 13 and comprises a skin-side layer 111, an outer layer 113, and a hair implantation layer 115.

[0015] Figure 2 shows a cross-section of the peripheral portion 11 of the wig base 10. The peripheral portion 11 has a three-layer structure. The peripheral portion 11 comprises a skin-side layer 111, an outer layer 113, and a hair-planted layer 115. The skin-side layer 111 comes into contact with the scalp of the wig base 10 user. The skin-side layer 111 is made of a first type of silicone. The first type of silicone contains a variety of silicones, including silicones used in prostheses. Because the first type of silicone contains silicones used in prostheses, it has high biocompatibility. Since the skin-side layer 111 that comes into contact with the scalp of the wig base 10 user is made of the first type of silicone, the user of the wig base 10 is less likely to experience discomfort when using the wig base.

[0016] The outer layer 113 is exposed to the outside when the wig base 10 is used. The outer layer 113 is made of a second silicone. The second silicone contains a variety of silicones, including silicones used in prostheses.

[0017] The first silicone and the second silicone may be addition-type silicones. In this case, it is preferable to make the mixing ratio of the agent B to the agent A in the second silicone smaller than the mixing ratio of the agent B to the agent A in the first silicone. For example, the mixing ratio of the agent A and the agent B in the first silicone may be 1:1, and the mixing ratio of the agent A and the agent B in the second silicone may be 10:1. Thereby, the first silicone is softer than the second silicone. Therefore, the skin-side layer 111 is softer than the outer layer 113. Since the skin-side layer 111 is softer than the outer layer 113, the stretchability of the wig base 10 is improved, and the wig base 10 is easily deformed into a shape along the user's head. Thereby, the wearing feeling of the wig base 10 is improved.

[0018] In the present embodiment, the outer layer 113 may be thicker than the skin-side layer 111. For example, the thickness of the skin-side layer 111 is 0.5 mm. The thickness of the outer layer 113 is 0.6 mm. The strain generated in the outer layer 113 when the wig base is used is larger than the strain generated in the skin-side layer 111. Since the outer layer 113 is thicker than the skin-side layer 111, the durability of the wig base 10 is improved.

[0019] The skin-side layer 111 may have a skin color. By mixing a pigment into the first silicone, the skin-side layer 111 comes to have a skin color. The skin color may be adjusted according to the color of the user's skin. The skin-side layer 111 may have the same color as the skin color of the user of the wig base 10.

[0020] The outer layer 113 may have transparency. When the skin-side layer 111 has a skin color and the outer layer 113 has transparency, the skin color of the skin-side layer 111 appears through during use, and the entire wig base 10 looks like a color close to the skin. Thereby, it becomes difficult to expose the use of the wig base 10.

[0021] The hair implantation layer 115 is a layer sandwiched between the skin-side layer 111 and the outer layer 113, and hair 21 is implanted in it. The hair implantation layer 115 is a woven fabric, preferably a woven fabric made of natural fibers using natural materials such as silk. The hair implantation layer 115 is implanted with hair 21 by attaching the hair 21 to the warp or weft threads that make up the hair implantation layer 115. The hair implantation layer 115 may have a skin color. The skin color is a color that matches the skin of the user of the wig base 10. The hair implantation layer 115 has a skin color by using skin-colored spun yarn in the weaving of the hair implantation layer 115. When the skin-side layer 111 has a skin color, the outer layer 113 has transparency, and the hair implantation layer 115 has a skin color, the wig base 10 will appear skin-colored when in use, and the unevenness of the hair implantation layer 115 will not be easily visible. This makes it even harder to detect the use of wig base 10.

[0022] The main body 13 is a woven fabric blended with silk. The main body 13 may be the same fabric as the flocked layer 115. The main body 13 is flocked with hair 21. The main body 13 is flocked with hair 21 by sewing threads containing hair 21 to the main body 13. The main body 13 may have a skin color. The main body 13 has a skin color by using skin-colored spun yarn in the weaving of the main body 13.

[0023] Figure 3 shows an example of a wig 20 according to this embodiment. The wig 20 comprises hair 21 and a wig base 10. Figure 4 shows a cross-section of the peripheral portion 11 of the wig 20. The hair implantation layer 115 of the peripheral portion 11 has hair 21 implanted in it. The hair implantation layer 115 has hair 21 implanted in it by tying the hair 21 to the hair implantation layer 115 with a lark's head knot.

[0024] Figure 5 shows a cross-section of the main body 13 of the wig 20. The main body 13 has hair 21 implanted in it. The hair 21 is attached to the main body 13 with a lark's head knot, thus the main body 13 has hair 21 implanted in it.

[0025] Figures 6 to 10 show one step in the manufacturing process of the wig 20. The wig 20 is manufactured by following the steps shown in Figure 6 to Figure 10 in order. Figure 6 shows one step in the manufacturing process of the peripheral portion 11 of the wig base 10. In the step shown in Figure 6, the skin-side layer 111, the hair-implanted layer 115, and the outer layer 113 are formed sequentially on the mannequin 31. The mannequin 31 mimics the head of the wig 20 user. The first silicone is applied to the forehead 311, crown 313, sides 315, and back of the head 317 of the mannequin 31. The first silicone is applied to the mannequin 31 using a brush or spray gun to ensure a uniform thickness. The skin-side layer 111 is formed by drying the first silicone.

[0026] After the skin-side layer 111 is formed, a silk-blend fabric is placed over the mannequin 31. The fabric is placed so as to completely cover the skin-side layer 111. After the fabric is placed, a second silicone is applied to the fabric. The second silicone is applied to the mannequin 31 using a brush or spray gun to ensure a uniform thickness. The second silicone impregnates the fabric. By drying the second silicone, the flocked layer 115 and the outer layer 113 are formed.

[0027] Figure 7 shows one of the processes for manufacturing the peripheral edge 11 of the wig base 10. After the outer layer 113 is formed, the skin-side layer 111, the hair-implanted layer 115, and the outer layer 113 are cut in a hollow circular shape. The dashed lines in Figure 7 indicate the cutting positions. The skin-side layer 111, the hair-implanted layer 115, and the outer layer 113 are cut at the dashed line positions using a precision knife. This completes the manufacturing of the peripheral edge 11. By manufacturing the peripheral edge 11 to match the head of a mannequin 31 that mimics the head of the wig user 20, it is possible to manufacture a peripheral edge 11 that matches the shape of the user's head.

[0028] Figure 8 shows the manufacturing process of the wig base 10. After the periphery portion 11 is manufactured, a silk-blend fabric is placed over the mannequin 31. The fabric is placed over the mannequin 31 so that it overlaps the vicinity of the inner circumference of the periphery portion 11. The fabric and the periphery portion 11 are fixed together by sewing or gluing. In this way, the wig base 10, comprising the periphery portion 11 and the main body portion 13, is manufactured.

[0029] Figure 9 shows the process of implanting hair 21 into the hair implantation layer 115 of the peripheral portion 11 and the main body portion 13. Hair 21-1 is implanted into the hair implantation layer 115 of the peripheral portion 11. Hair 21-1 is tied to the hair implantation layer 115 with a lark's head knot, thereby implanting hair 21-1 into the hair implantation layer 115. Hair 21-2 is implanted into the hair implantation layer 115 of the peripheral portion 11 and the main body portion 13. Hair 21-2 is tied to the hair implantation layer 115 and the main body portion 13 with a lark's head knot, thereby implanting hair 21-2 into the hair implantation layer 115 and the main body portion 13. As a result, the peripheral portion 11 and the main body portion 13 are firmly bound together by hair 21-2. Hair 21-3 is implanted into the main body portion 13. The hairs 21-3 are attached to the main body 13 using a lark's head knot, thereby implanting the hairs 21-3 into the main body 13.

[0030] Figure 10 shows the process of applying the protective layer 117. Depending on the thickness and knotting of the hair 21, the hair 21 may be exposed from the skin-side layer 111. The protective layer 117 prevents the hair 21 exposed from the skin-side layer 111 from coming into contact with the scalp of the wig user 20. The protective layer 117 is made of first-grade silicone. The protective layer 117 prevents the hair 21 from coming into contact with the scalp of the wig user 20, improving the comfort of the wig 20. In addition, the protective layer 117, which has few irregularities, comes into contact with the scalp of the wig user 20, making the wig 20 less likely to slip and, consequently, less likely to come off. The wig 20 is manufactured in this manner.

[0031] In another embodiment, the hair implantation layer 115 of the wig base 10 may have higher elasticity than the skin-side layer 111 and the outer layer 113. The wig base 10 is a composite material consisting of the skin-side layer 111, the outer layer 113 and the hair implantation layer 115. By having the hair implantation layer 115 have higher elasticity than the skin-side layer 111 and the outer layer 113, the wig base 10 can be stretched beyond the yield strain of the skin-side layer 111 and the outer layer 113. The hair implantation layer 115 may be a fiber layer. The hair implantation layer 115 may be a knitted fabric or the fibers themselves. Preferably, the hair implantation layer 115 is a woven fabric made of synthetic fibers.

[0032] The hair implantation layer 115 may have greater elasticity in the front-to-back direction of the head than in the left-to-right direction. In Figure 1, the dashed line represents the front-to-back direction of the head. In the fabric constituting the hair implantation layer 115, the threads arranged in the front-to-back direction of the head may be thinner than the threads arranged in the left-to-right direction of the head. The relative thinness of the threads arranged in the front-to-back direction of the head improves the elasticity in the front-to-back direction of the head. Because the user of the wig base 10 may have protrusions at the lambda suture of their head, the wig base 10 is prone to shifting in the front-to-back direction of the head. By having high elasticity in the front-to-back direction of the head of the hair implantation layer 115, the wig base 10 becomes easier to stretch in the front-to-back direction and less likely to shift.

[0033] When manufacturing a wig base 10 with high elasticity in the front-to-back direction of the hair implantation layer 115, an anisotropic fabric is used in the process shown in Figure 8. By placing the fabric over the mannequin 31 so that the relatively elastic direction of the fabric coincides with the left-to-right direction of the paper in Figure 8, a wig base 10 with high elasticity in the front-to-back direction of the hair implantation layer 115 can be manufactured.

[0034] Figure 11 shows a wig base 10 according to another embodiment. The wig base 10 comprises a peripheral portion 11, a main body portion 13, a sideburn portion 15, and a nape portion 17. The sideburn portion 15 and the nape portion 17 are connected to the peripheral portion 11. The sideburn portion 15 is connected to the peripheral portion 11 so as to contact the sideburns of the wig base 10 user. The nape portion 17 is connected to the peripheral portion 11 so as to contact the nape of the nape of the wig base 10 user.

[0035] The sideburns 15 and nape of the neck 17 have a skin-side layer 111, an outer layer 113, a hair implantation layer 115, and a reinforcing layer 119. The reinforcing layer 119 is formed on the outer layer of the outer layer 113 and is made of a third silicone. The third silicone is harder than the first and second silicones. The sideburns 15 and nape of the neck 17 are prone to curling because they come into contact with areas with small curvature, but the hardness of the third silicone compared to the first and second silicones prevents the sideburns 15 and nape of the neck 17 from curling.

[0036] The flocked layer 115 may be a woven fabric made of natural fibers. Alternatively, the flocked layer 115 may be a woven fabric made of a blended yarn of synthetic fibers and natural fibers. The main body 13 may be a woven fabric made of synthetic fibers, or a woven fabric made of a blended yarn of synthetic fibers and natural fibers. The flocked layer 115 and the main body 13 are not limited to woven fabrics, but may be knitted fabrics. The flocked layer 115 may be a layer made of synthetic resin instead of a woven or knitted fabric.

[0037] The hairs 21 are attached to the hair follicle layer 115 and the main body 13 using knots similar to those used when tying a string. Examples of knots used include a clove hitch and a left-right knot. If the hair follicle layer 115 is made of synthetic resin, the hairs may be implanted instead of being attached.

[0038] Multiple hair implant layers 115 may be provided. The multiple hair implant layers 115 may be made of the same material or different materials. When manufacturing a wig base 10 with multiple hair implant layers 115, in the process shown in Figure 6, after the skin-side layer 111 is formed, multiple fabrics are placed over the mannequin 31. After the multiple fabrics are placed over the mannequin, a second silicone is applied to the multiple fabrics to manufacture a wig base 10 with multiple hair implant layers 115. By providing multiple hair implant layers 115, the wig base 10 becomes less prone to deformation, and the edges of the wig base 10 are further prevented from curling up when worn. In this case, the entire hair implant layer 115 may be made of multiple layers, or only a part of the hair implant layer 115, such as the central or peripheral region, may be made of multiple layers.

[0039] In the wig base 10 according to other embodiments, the main body portion 13 may extend to the peripheral portion 11 and also serve as the hair implantation layer 115. In this embodiment, the peripheral portion 11 is formed by sandwiching the peripheral portion of the main body portion 13 between the skin-side layer 111 and the outer layer 113.
