[0018] The present invention will now be described through embodiments thereof, but these embodiments do not limit the invention as described in the claims. Furthermore, not all combinations of features described in the embodiments are necessarily required for the solution of the invention.

[0019] Figure 1 This is a schematic diagram illustrating the overall shape of the wig 10. The wig 10 is worn on the user's head, covering the entire head or a portion thereof.

[0020] The wig 10 includes a molding base 200 and multiple hairs 100 implanted in the molding base 200. The hairs 100 are artificial hairs and / or natural hairs.

[0021] In this embodiment, the wig 10 maintains a bowl-shaped form that protrudes towards the hair 100 using the molding base 200 itself. This shape is formed according to the shape of each user's head, and such a wig 10 is called a custom wig. Here, in custom wigs, it is desirable to maintain the shape along the head using itself; therefore, synthetic fibers are considered as the molding base 200. However, users with sensitive skin who experience itching or other irritation when synthetic fibers come into contact with the skin cannot use a synthetic fiber molding base 200.

[0022] Figure 2 This is a partial enlarged cross-sectional view of the molding substrate 200. The molding substrate 200 includes: a skin-side layer 220 disposed on the user's head side, i.e., the skin side; an outer layer 240 located on the side opposite to the skin; and an adhesive 230 that bonds the skin-side layer 220 and the outer layer 240 together. On the skin-side surface of the skin-side layer 220 ( Figure 2 The lower surface of the adhesive 230 is formed with a non-adhesive layer 228 that ensures that the adhesive 230 does not seep out. As a result, the natural fibers come into contact with the user's scalp, while the adhesive and synthetic fibers do not come into contact with the scalp, thus providing a comfortable feel even for users with sensitive skin.

[0023] Figure 3This is a schematic diagram illustrating the skin side layer 220. The skin side layer 220 is a fabric of natural fibers. Natural fibers are plant fibers and / or animal fibers, examples of which include cotton, linen, silk, wool, etc. In the case of plant fibers, organically cultivated so-called organic fibers are more preferred.

[0024] Figure 3 The skin-side layer 220 shown is a transparent fabric woven from warp yarns 222 and weft yarns 224 in a plain weave, with gaps 226 that allow for visual permeability. Cicada wing yarn is an example of such a transparent fabric. Other examples of transparent fabrics include gauze and tulle weaves. A thinner skin-side layer 220 is preferable, for example, preferably 0.12 mm or less. The skin-side layer 220 is dyed a skin-toned color with a reactive dye.

[0025] Figure 4 This is a schematic diagram illustrating the outer layer 240. The outer layer 240 is a synthetic fiber fabric. Examples of synthetic fibers include polyester, nylon, acrylic, and polyurethane. The synthetic fiber is shaped by heating, preferably by itself maintaining the shaped form. Incidentally, using this synthetic fiber, even when adhered to the skin side layer 220, it can maintain its shaped form as a molding substrate 200.

[0026] Figure 4 The outer layer 240 shown is a plain-woven fabric composed of warp yarns 242 and weft yarns 244, and is a see-through fabric with gaps 246 that allow for visual transparency. A cicada-wing yarn is an example of such a see-through fabric. A thin outer layer 240 is preferable, for example, preferably 0.12 mm or less. Other examples of see-through fabrics include leno and gauze weaves. The outer layer 240 is dyed a skin-toned color with disperse dyes.

[0027] When comparing the skin lateral layer 220 and the outer layer 240, it is preferable that the outer layer 240 has a greater sense of perspective. The magnitude of the perspective corresponds, for example, to the average size of the gaps, where the area of ​​gap 246 is larger than the area of ​​gap 226. Alternatively, the magnitude of the perspective can also be compared by the area occupied by the filament per unit area when viewed from above.

[0028] Furthermore, when comparing the skin side layer 220 and the outer layer 240, it is preferable that the skin side layer 220 is colored with a stronger blue and / or a weaker red compared to the outer layer 240. Thus, when viewed from one side of the outer layer 240, the skin side layer 220 is partially visible through the gaps 246 of the outer layer 240, and overall appears to have a deeper skin tone that is closer to the natural skin tone of the scalp. Additionally, from this perspective, the skin side layer 220 may not be a see-through fabric. Furthermore, the skin side layer 220 and / or the outer layer 240 can also be woven fabric, as long as they can be shaped.

[0029] Figures 5 to 7 This is a conceptual diagram illustrating the manufacturing method of the molded substrate 200. Figure 5 This is an example of a method for applying adhesive 230.

[0030] Prepare Figure 4 The fabric of the outer layer 240 shown is cut into an approximately elliptical shape according to the area to be covered on the head. On one side of the outer layer 240, adhesive 230 is applied in a so-called spider's nest pattern, consisting of radial lines and concentric elliptical lines. Alternatively, instead of a spider's nest pattern, it can be applied to the entire surface or a web. In either case, a method and amount of application that maintains strength against peeling during use and forms a non-adhesive layer 228 on the skin side when adhered to the skin side layer 220 is preferred. Adhesive 230 can be exemplified as a polyamide resin, but can also be polyurethane-based.

[0031] Figure 6 This is an example of a method for bonding the outer layer 240 and the skin-side layer 220 together. The adhesive 230 side of the outer layer 240, coated with adhesive 230, is then bonded to... Figure 3 The skin side layers 220 shown are overlapped and then heated and pressurized. This method is also known as thermal fusion. This forms a substrate 250, which is achieved through a layered structure of the outer side layer 240 and the skin side layers 220.

[0032] Figure 7 This is an example of a method for forming a molded substrate 200. In Figure 7 In this process, a mold 20 is prepared that mimics the shape of the user's head. Alternatively, the user's head can be molded using vinyl resin, plastic wrap, a 3D scanner, or the like.

[0033] While the substrate 250 is aligned with the mold 20, pressure and heat are applied, for example, using a soldering iron. This forms a molded substrate 200 that mimics the mold 20. Hair 100 is then implanted into the molded substrate 200 to form… Figure 1 Wig 10 is shown.

[0034] [Example 1]

[0035] As the skin side layer 220, a 0.12mm thick fabric made of 140 monofilament cotton woven into a sheer yarn is used and dyed light brown. As the outer side layer 240, a 0.12mm thick fabric made of 20 denier nylon woven into a sheer yarn is used and dyed light skin tone.

[0036] A polyamide resin adhesive 230 is applied in a spider-nest pattern to one side of the outer layer 240 and then heat-fused to the skin side layer 220. This forms a non-adhesive layer 228 on the skin side layer 220, resulting in a substrate 250 with sufficient peel strength for use.

[0037] By heating the base 250 to approximately 100 degrees using the mold 20, a shaped base 200 that maintains its shape in imitation of the head is obtained. This allows for the creation of a custom-made wig 10 that can be comfortably used by users with sensitive skin.

It will be apparent to those skilled in the art that various modifications or improvements can be made to the above embodiments. As can be seen from the claims, embodiments resulting from such modifications or improvements are also included within the technical scope of the present invention.
