Description

Wig base, wig, wig base manufacturing method

[0001] The present invention relates to a wig base, a wig, and a method for manufacturing a wig base.

[0002] When hair is lost from the entire head due to chemical treatment, alopecia, etc., wigs are used to replace the lost hair. Full-head wigs are made by attaching human hair (hereinafter referred to as "human hair") or artificially created hair (hereinafter referred to as "artificial hair") to a wig base.

[0003] BACKGROUND ART Conventionally, wigs have been known in which artificial skin made of synthetic resin is used for the parting portion of a wig base, etc., in order to obtain a natural appearance and prevent the wig from slipping out of place.

[0004] However, conventional wig bases have fabric sewn to fit the head, which can lead to issues such as a poor fit, the risk of slipping or coming off, poor breathability, and a lack of lightness.

[0005] To address the above-mentioned problems, a wig has been proposed in which hair is attached to a wig base made of a mesh-like elastic material (Patent Document 1).

[0006] JP 2007-217850 A

[0007] However, wig bases made of mesh-like elastic material can sometimes cause the wig base to tighten around the head or roll up due to the elastic force, leaving room for improvement in terms of texture and shape stability.

[0008] The present invention has been made in consideration of the above circumstances, and its problem to be solved is to provide a wig base and a wig that have a better texture and shape stability than conventional wig bases, as well as a method for manufacturing the wig base.

[0009] [Wig Base] The wig base of the present invention has a base, which is formed of a covering yarn in which the outer periphery of a core material is covered with a covering material, and heat-fusible yarn is used as the core material and / or the covering material.

[0010] [Wig] The wig of the present invention is a wig base of the present invention with human hair and / or artificial hair implanted therein.

[0011] [Method for manufacturing a wig base] The method for manufacturing a wig base of the present invention is a method for covering a head model with a tubular net formed of covering yarns in which the outer periphery of heat-sealed yarns is covered with a covering material and / or covering yarns in which the outer periphery of a core material is covered with heat-sealed yarns, and then heating the tubular net to form the tubular net into a shape that conforms to the head model.

[0012] According to the present invention, it is possible to provide a wig base and a wig that have a better texture and better shape stability than conventional wig bases and wigs, as well as a method for manufacturing a wig base.

[0014] An example of an embodiment of the present invention will be described with reference to the drawings. As an example, a wig 30 shown in Fig. 1(a) comprises a wig base 10 and hair 20.

[0015] <Wig Base> As shown in FIGS. 1( a ) and 1 ( b ), the wig base 10 of this embodiment includes a base 11 , a whorl part 12 , and a stopper part 13 .

[0016] - Base - The base 11 is the foundation of the wig base 10. The base 11 in this embodiment is a mesh-like (net-like) member shaped to fit the shape of the wearer's head, and is preferably seamless. Being seamless prevents irritation to the head caused by sewing threads, resulting in a comfortable fit. Because the base 11 is mesh-like, it is lightweight and has excellent breathability. The base 11 can be manufactured using various machines, such as a seamless knitting machine, a flat knitting machine, or a hosiery machine, or it can also be manufactured by hand knitting.

[0017] Specifically, it can be made using plain knitting (jersey knitting and stockinette knitting), rib knitting (rib knitting, rib knitting, garter knitting), purl knitting (garter stitch, links, double head knitting), thermal knitting (waffle knitting, honeycomb knitting), pique knitting, reversible pique knitting (reversible mesh), smooth knitting (interlock knitting), reverse pile knitting (fleece knitting, fleece knitting), jacquard knitting, intarsia knitting, etc.

[0018] The base 11 of this embodiment is configured using a covering yarn 14. In this specification, the covering yarn includes a yarn material 14 in which a covering material (sheath yarn) 14b is wound in a coil shape around the outer periphery of a core material 14a, as shown in Figures 2(a) and 2(b).

[0019] The covering yarn 14 may be a single covering yarn in which the covering material 14b is wrapped around the yarn in a single layer as shown in FIG. 2(a) (single covering yarn), or a double covering yarn in which the covering material 14b is wrapped around the yarn in a double layer as shown in FIG. 2(b) (double covering yarn).

[0020] The core material 14a can be a thermal fusion yarn. Thermal fusion yarn has the property of melting when heated and solidifying (curing) when cooled. Examples of thermal fusion yarn include yarns made from various synthetic fiber materials such as nylon (polyamide) and polyester, which have lower melting points than normal. The covering yarn 14 using thermal fusion yarn as the core material can be molded into a predetermined shape by applying heat and curing, thereby maintaining the shape.

[0021] The heat-sealable yarn is, for example, a low-melting nylon / polyamide fiber or a low-melting polyester fiber, and also various thermoplastic polymers and thermoplastic elastomers with adjusted melting points can be used.

[0022] The thermal fusion yarn may be made of two or more different fiber materials. For example, by using a thermal fusion yarn with a double structure, in which a synthetic fiber material with a normal melting point is used in the center and a synthetic fiber material with a lower melting point is used around the center to form a core-sheath structure, the surrounding low-melting-point material melts when heated, thereby functioning as a thermal fusion yarn, while the center portion does not melt when heated and can maintain a predetermined shape, elasticity, etc. Without being limited to this embodiment, the thermal fusion yarn may be a composite material made of two or more materials with different melting points.

[0023] The heat-sealing yarn is, for example, a nylon fiber that melts in hot water at about 71°C and dry heat at about 118°C (105 to 125°C), or in hot water at about 62°C and dry heat at about 105°C (95 to 115°C).

[0024] The heat-sealed yarn is, for example, a multiple-core / sheath composite filament (heat-sealed polyester fiber) that has a core made of a high-viscosity polyester resin with a melting point of about 250°C and a sheath made of a crystalline polyester resin with a melting point of about 180°C (low melting point), which is lower than the melting point of the core.

[0025] The heat-sealing yarn is, for example, a low-melting polyamide fiber having a melting point of 98 to 130°C.

[0026] The heat-sealing yarn may have a multifilament structure using a plurality of filaments, which are easily integrated and fused together when melted.

[0027] As the heat-sealing yarn, for example, a composite filament using a plurality of filaments each having a sheath portion disposed on the outside of a core portion can be used.

[0028] The heat-fusible yarns shown here are merely examples, and various types of heat-fusible yarns can be used. For example, those with a hot water melting point of about 60 to 130°C, preferably about 60 to 90°C, and those with a dry heat melting point of about 90 to 150°C, preferably about 100 to 135°C, can be used.

[0029] In addition to the hot water melting point and dry heat melting point, the melting point of the heat-fusible yarn can be evaluated by various methods, for example, by melting point measurement according to JIS L1013: 2010. When evaluated by this method, the heat-fusible yarn used as the core material 14a preferably has a melting point of 90 to 140°C.

[0030] The covering material 14b covers the outer periphery of the core material 14a. Generally, a molded product using heat-sealing yarn becomes hard when the heat-sealing yarn melts and solidifies, and therefore, if the heat-sealing yarn is used as is, it may cause discomfort when it comes into contact with the skin.

[0031] In this regard, by providing the covering material 14b around the outer periphery of the heat-fusible thread, it becomes more comfortable against the skin and reduces discomfort when it comes into contact with the skin. The covering material 14b also has the effect of increasing the strength of the core material 14a and, in turn, the strength of the wig base 10, thereby reducing the risk of damage to the wig base 10 when the hair is implanted.

[0032] The covering material 14b can be made of various materials, such as nylon, polyester, rayon, polyurethane, acrylic, polypropylene, polyethylene, synthetic protein, thermoplastic elastomer, cotton, silk, hemp, paper, wool, etc. When a thermoplastic or thermosetting chemical fiber is used for the covering material 14b, it is desirable that the melting point of the thermosetting fiber used as the core material be higher, preferably by 10°C or more, and more preferably by 20°C or more. It is preferable to use a covering material 14b that is the same color as or similar to the wearer's skin (scalp) or hair color.

[0033] In addition to the above, the covering material 14b may be made of synthetic fibers or natural fibers having various functions such as sweat absorption, quick drying, antibacterial properties, deodorizing properties, deodorizing properties, cool to the touch, etc. By using synthetic fibers or natural fibers having such functions (functional fibers), the wig base 10 can be endowed with the various functions of the covering material 14b.

[0034] For example, if a functional fiber is used that has the function of controlling the pH of the area where sweat adheres to a weak acidity, the pH of the area where sweat adheres can be controlled to a weak acidity, thereby giving the fiber the function of suppressing the growth of harmful bacteria.

[0035] The thickness of the fibers used for the heat-fusible threads and covering material 14b can be any thickness taking into consideration the strength and thickness of the wig base 10, but for example, a thickness of 10 to 200 denier is preferably used, and 20 to 100 denier is more preferable. Denier here means a unit of measurement for fineness (thickness of fiber).

[0036] Generally, heat-sealing threads are used when they are melted and fixed or bonded to other components, and since providing a coating material 14b on the outer periphery may reduce the fixing or adhesive strength to other components, the outer periphery of the heat-sealing thread is not usually covered with a coating material 14b.

[0037] In the wig base 10 of this embodiment, the main expectation of the heat-sealed yarn is shape stability (ability to maintain a state of fitting to the head shape). In this regard, as will be explained in the following examples, in the wig base 10 of the present invention, even when using covering yarns 14 in which a covering material 14b is provided on the outer periphery of the heat-sealed yarn, shape stability is not impaired and sufficient shape stability can be ensured.

[0038] Furthermore, when the wig base 10 is made of woven fabric as in the past, scraps are produced when it is cut, but when the covering yarn 14 is used to make the base 11, no scraps are produced, reducing the environmental impact. In addition, the base 11, which is knitted with a single covering yarn 14, has no seams, so it feels good against the skin and can also be made lighter overall.

[0039] The above embodiment is merely one embodiment of the present invention, and there are various other variations in the configuration of the wig base of the present invention. For example, when using covering threads 14 for the wig base 10, both the core material 14a and the covering material 14b may be made of the above-mentioned heat-sealing threads.

[0040] In this case, for example, by changing the materials of the heat-sealed yarns for the core material 14a and the covering material 14b, and using heat-sealed yarns with excellent shape stability for the core material 14a and heat-sealed yarns with good texture for the covering material 14b, it is possible to create a wig base with excellent shape stability while maintaining the texture.

[0041] Furthermore, if texture is not so important, the covering material 14b can be a heat-sealed yarn and the core material 14a can be a normal synthetic fiber or natural fiber, as opposed to the present embodiment. A covering material 14b using a heat-sealed yarn and a core material 14a using a normal synthetic fiber or natural fiber is more likely to melt when heated from the surface than a covering yarn 14 using a heat-sealed yarn as the core material 14a, and a variety of molding methods can be used.

[0042] Furthermore, when using a double-covered yarn, it is also possible to use two different materials for the covering, such as two different ordinary natural or synthetic fibers, two different heat-sealed yarns, or one heat-sealed yarn and the other ordinary fiber material.

[0043] In short, the materials to be used for the core material 14a and the covering material 14b, and the materials to be used for each of the two covering materials 14b when double covering yarn is used, are matters that can be appropriately changed by a person skilled in the art in view of the disclosure of this specification in order to pursue the desired texture, shape stability, and ease of molding.

[0044] - Whorl part - The whorl part 12 is a component attached to the wig base 10 near the top of the head. The whorl part 12 has hair (hereinafter referred to as "whorl hair") 12b implanted in a base part 12a made of artificial skin, knitted fabric, woven fabric, lace material, etc. The base part 12a is preferably the same color as the base part 11 or a similar color, in other words, the same color as the wearer's skin or a similar color. The artificial skin is used to make the parting area look natural, like the wearer's bare skin.

[0045] The whorl hair 12b can be made of human hair, artificial hair, etc. The whorl hair 12b can be made by combining multiple human hairs or artificial hairs of the same length or different lengths. The whorl hair 12b is planted so that it penetrates from the outer surface of the wig base 10 to the inner surface, and then penetrates back to the outer surface again. The whorl hair 12b is planted so that it looks like a natural whorl.

[0046] The whorl part 12 is configured as a separate part from the base 11. By configuring the whorl part 12 as a separate part from the base 11, it is possible to replace only the whorl part 12, which wears out quickly. The whorl part 12 can be attached to the base 11 by crimping, sewing, or other methods. The whorl part 12 can also include not only the whorl part but also the parting part. If artificial skin is used, the parting part can be made to look natural, like the skin.

[0047] -Slip prevention parts- The slip prevention parts 13 are components that prevent the wig base 10 from slipping or coming off. The slip prevention parts 13 are provided on the inner surface of the base 11 around the face (the part that comes into contact with the wearer's skin). The slip prevention parts 13 are also expected to have the effect of reinforcing the wig base 10 and preventing fraying.

[0048] The anti-slip part 13 can be attached to the base 11 by crimping, sewing, or other methods. The anti-slip part 13 is ring-shaped (hairband-shaped) and spans the left head, front head, right head, and back of the head, and the parts for both ears are cut so that both ears are exposed.

[0049] The slip-preventing part 13 can be made of, for example, a thermoplastic elastomer, silicone rubber, natural rubber (NR), styrene butadiene rubber (SBR), chloroprene rubber (CR), acrylonitrile butadiene rubber (NBR), urethane rubber (U), thermoplastic polyurethane (TPU), etc. The slip-preventing part 13 is preferably made of a material with greater friction resistance than the covering thread 14.

[0050] The slip-preventing part 13 may also be provided with a size adjuster 15. The adjuster 15 may be, for example, a thin plate having two holes, a string to be inserted into the holes, and a string holder to hold the string (a so-called pig nose with a lock), a hook-and-loop fastener, or the like. Other adjusters may also be used.

[0051] Alternatively, the stopper part 13 can be manufactured using a shape memory polymer that can be output using a 3D printer. The shape memory polymer here refers to a polymer that has the property of being able to restore its original shape by heating it to a predetermined temperature or higher even if its shape is deformed after molding. The shape memory polymer may be a shape memory polymer filament or the like.

[0052] The wig is attached to the head using a shape memory polymer, and the slippage prevention part 13 is heated to a predetermined temperature with a hairdryer or the like to restore it to its original shape, and then the wig is fitted to the head and cooled again, thereby making the wig fit the head even better.

[0053] The predetermined temperature is the so-called glass transition point (Tg), and is approximately 50 to 70° C., preferably approximately 55° C. If the material restores its shape at temperatures above 55° C., in other words, if the material does not restore its shape at temperatures below 55° C., it is possible to prevent inadvertent deformation even during high temperature periods such as midsummer.

[0054] When a shape memory polymer is output using a 3D printer, the shape can be flat (e.g., sheet-like) or three-dimensional. Also, the shape can be tailored to a specific person's head (head model M) or a general-purpose shape.

[0055] For example, when outputting parts with general-purpose shapes (hereinafter referred to as "general-purpose parts"), it is preferable to use the general-purpose parts by shaping them to fit individual heads using a hair dryer, etc. It is preferable to prepare general-purpose parts in multiple sizes (for example, small, medium, and large) in advance.

[0056] The slip-preventing part 13 can be made up of one part (for example, a ring-shaped part) or multiple parts. For example, when manufacturing the slip-preventing part 13 using a shape-memory polymer, a front part 13a and a back part 13b can be prepared and connected to each other with hook-and-loop fasteners, tape, rubber, an adjuster, or the like to form a ring shape.

[0057] The front part 13a and the back part 13b can have various shapes. Examples of the shape of the front part 13a are shown in Figures 3(a) to 3(d), and examples of the shape of the back part 13b are shown in Figures 4(a) to 4(d). The front part 13a and the back part 13b can also be made mesh-shaped, as shown in Figures 5(a) to 5(d) and 6(a) to 6(d).

[0058] In addition, the front part 13a and the back part 13b may have a frame shape with multiple inner members 13e inside a peripheral frame 13d as shown in Figures 7(a) and 7(b). The inner members 13e may be arranged vertically, horizontally, or diagonally, regularly or irregularly. In some cases, the peripheral frame 13d may be omitted, and the bag may be constructed with only multiple inner members 13e connected together.

[0059] When a shape memory polymer is used, it can be used as the slip prevention part 13 by itself, but it is preferable to provide an inner surface part 13f made of a soft material (e.g., thermoplastic elastomer, silicone, etc.) that is less likely to damage the skin on the surface that comes into contact with the wearer's skin.

[0060] The shape of the inner surface part 13f can be a ring shape that conforms to the shape of the head, or a shape similar to the shape of the parts made of shape-memory polymer (front part 13a and back part 13b).

[0061] For example, when a front part 13a having a framework shape as shown in Fig. 7(a) is used, it is preferable to attach an inner part 13f having the same framework shape as shown in Fig. 7(c) to the surface that comes into contact with the wearer's skin. Similarly, when a back part 13b having a framework shape as shown in Fig. 7(b) is used, it is preferable to attach an inner part 13f having the same framework shape as shown in Fig. 7(d) to the surface that comes into contact with the wearer's skin.

[0062] <Hair> The hair 20 is a part that constitutes the hair of the wig 30. Like the whorl hair 12b, the hair 20 can be made of human hair, artificial hair, etc. The hair 20 can be made by combining multiple human hairs or artificial hairs of the same length or different lengths.

[0063] The hair 20 is planted so as to penetrate from the outer surface to the inner surface of the wig base 10 (specifically, the base 11 and the stopper part 13), and then penetrate back to the outer surface again. In this embodiment, the wig base 10 is made of covering threads 14 in which the outer periphery of the core material 14a is covered with a covering material 14b, so that the wig base 10 is stronger than conventional wig bases and the risk of damage to the wig base 10 during planting can be reduced.

[0064] When hair 20 is planted in wig base 10, knots may form on the inner surface of wig base 10, which may rub against the skin and cause itching. To prevent this, a backing fabric or the like may be provided on the inner surface of wig base 10 after hair 20 has been planted, to prevent the knots from directly touching the skin.

[0065] The wig base 10 and wig 30 described here are merely examples, and the configurations of the wig base 10 and wig 30 of the present invention are not limited to those of this embodiment. The wig base 10 and wig 30 of the present invention can be modified by adding, omitting, or replacing components within the scope of achieving the intended purpose. For example, in a modified example, the wig base 10 of the present invention may not have either or both of the whorl part 12 and the anti-slip part 13.

[0066] Conversely, in a further modified example, the material of the wig base 10 of the present invention does not use heat-sealed thread, but is instead made of ordinary natural or synthetic fibers (see paragraph 0033, etc.) that can be used for the covering material 14b, and instead a shape memory polymer is used for the anti-slip part 13, thereby providing a wig with excellent texture and fit to the head, which is also within the scope of the present invention.

[0067] In the above embodiment, the wig 30 is exemplified as one in which the base 11, the whorl part 12, the anti-slip part 13 and the hair 20 are integrally constructed, but as a variant, the wig 30 can also be constructed from two or more separate parts.

[0068] 8 shows an example of a wig 30 made up of two or more separate parts, in which the base 11, whorl part 12, and hair 20 are made up as an integrated part, and the stopper part 13 is made up as a separate part. The latter functions as a base part to be attached to the head, and the former functions as a main part to be attached to the base part (stopper part 13) attached to the head.

[0069] The basic configuration of the base 11, whorl part 12, and hair 20 of this modified example is the same as that of the above embodiment. The difference is that the base 11 is provided with a fixture 16 and a sideburn sticker attachment part 17. Below, we will mainly explain the parts that are different from the above embodiment, and will omit explanations of the parts that are the same as those of the above embodiment as appropriate.

[0070] As in the above embodiment, the base 11 of this modification is also a seamless (whole garment) member shaped to fit the head. As shown in Fig. 9, the periphery of the opening at the lower end of the base 11 has protruding portions that protrude downward from the other portions of the periphery of the opening at positions corresponding to the sideburns and the nape of the neck (hereinafter, the protruding portions at the positions corresponding to the sideburns will be referred to as "first protruding portion 11a" and "second protruding portion 11b," and the protruding portion at the position corresponding to the nape of the neck will be referred to as "third protruding portion 11c"). The portions corresponding to the ears have upward recessed portions 11d that are recessed to accommodate the ears.

[0071] 9 are generally trapezoidal, the first protruding portion 11a and the second protruding portion 11b may have various shapes, such as an arc-shaped tip, etc. Similarly, the third protruding portion 11c is generally trapezoidal, but the third protruding portion 11c may have various shapes, such as an arc-shaped tip, etc.

[0072] At the lower end of the first protruding portion 11a and the second protruding portion 11b, there is provided a sideburn sticker attachment portion 17 for attaching a sideburn sticker S1 (FIGS. 13(a) and 13(b)). The sideburn sticker S1 is a sticker with a picture or photograph of sideburns printed (displayed) on its surface, and is used by attaching one part to the sideburn sticker attachment portion 17 and the other part to the front of the wearer's ear.

[0073] The sideburn sticker attachment part 17 can be made of a material different from that of the base part 11, such as polyurethane, polyurethane-based thermoplastic elastomer, elastomer, or other material that makes it easy to attach the sideburn sticker S1. The sideburn sticker attachment part 17 can be attached to the base part 11 by various adhesive means such as adhesive or adhesive tape.

[0074] The sideburn sticker attachment portion 17 can be the same color as or a similar color to the wearer's skin, or can be colorless and transparent. The shape, material, and color of the sideburn sticker attachment portion 17 may be other than those described above. The sideburn sticker attachment portion 17 is preferably provided in a position hidden by the hair 20 (inside the hair 20) when the hair 20 is down.

[0075] The fixing device 16 is a member for fixing the integrally constructed base 11, whorl part 12, and hair 20 (main part) to the slippage prevention part 13 (base part). For example, a comb-shaped fastener as shown in Fig. 9 or a clip with clamping parts on both longitudinal ends can be used as the fixing device 16. Fixing devices of other shapes and structures can also be used.

[0076] One fastener 16 may be provided, but two or more may also be provided. In the example shown in Fig. 9, one fastener is provided near the center of the back of the head, and one on each of the two outer sides (a total of three fasteners 16). Of the three fasteners 16, the central fastener 16 is used to engage with the band 13k of the nape part 13g, and the two outer fasteners 16 are used to fasten the nape part to the base 13i.

[0077] By providing the fasteners 16 in such positions, it is possible to prevent the main body parts from lifting not only near the center of the back of the head but also on both sides. When providing two or more fasteners 16, the same fasteners may be used, but different fasteners may also be used. Furthermore, the positions and number of fasteners 16 shown in Figure 9 are merely examples, and other positions and numbers of fasteners 16 may also be used.

[0078] Next, we will explain the slip-prevention part 13 (base part) of this modified example. The slip-prevention part 13 is a part that is attached to the head and serves as a base part for fixing the base part 11, whorl part 12, and hair 20 (main part), which are constructed as an integrated unit.

[0079] 10, the slip-prevention part 13 of this modification includes a front part 13a, a nape part 13g, and a connector 13h. The front part 13a and the nape part 13g are connected by the connector 13h, such as a hook-and-loop fastener, tape, rubber, hook, or adjuster, to form a continuous ring shape.

[0080] The front part 13a has a two-layer structure made by bonding a shape-memory material having shape memory and temperature dependency and a durable mesh material, with the shape-memory material facing the skin and the mesh material facing outward.

[0081] The shape-memory material used in this modification has the property of sensing body temperature and changing flexibly. Because this material does not have a very high tensile strength, durability is ensured by attaching a mesh material. In addition, because this material does not have a very high breathability, breathability is ensured by providing micropores. The micropores can be formed using a laser or the like.

[0082] The configuration and material of the front part 13a shown here are merely examples, and the front part 13a may have a different configuration and material. The front part 13a may be the same as the front part 13a in the above embodiment.

[0083] The nape part 13g of this modified example is a part that is applied to a position corresponding to the nape of the head, and includes a mesh-like (net-like) nape part base 13i that serves as a base, and hair (hereinafter referred to as "rear hair") 13j provided on the nape part base 13i. The rear hair 13j can be made of human hair and / or artificial hair, and can be configured by combining multiple human hairs and / or artificial hairs of the same length or different lengths.

[0084] The rear hair 13j can be implanted in the same manner as the hair 20 implanted in the whorl hair 12b or the base 11, or can be attached to the surface of the nape part base 13i by sewing or gluing.

[0085] The nape part base 13i is provided on its inner surface (skin side) with a lining material. The lining material is a material that comes into direct contact with the skin and can be made of thermoplastic elastomer, silicone rubber, natural rubber (NR), styrene butadiene rubber (SBR), chloroprene rubber (CR), acrylonitrile butadiene rubber (NBR), urethane rubber (U), thermoplastic polyurethane (TPU), or the like.

[0086] The nape sticker attachment section 18 is provided at the lower end of the nape part 13g of this modified example for attaching a nape sticker S2 (described later) (FIGS. 14(a) and 14(b)). The nape sticker S2 is a sticker on which a picture or photograph of the nape is printed (displayed), and is used by attaching a part of it to the nape sticker attachment section 18 and another part to the wearer's neck.

[0087] The nape sticker attachment part 18 is a separate member from the nape part 13g. The nape sticker attachment part 18 is attached to the nape part 13g (nape part base part 13i) by various adhesive means such as adhesive or adhesive tape.

[0088] In this modification, a horizontally long, trapezoidal thin piece protruding below the bottom end of the nape part 13g is used as the nape sticker attachment part 18. The nape sticker attachment part 18 can be made of a material (such as polyurethane, polyurethane-based thermoplastic elastomer, or elastomer) that makes it easy to attach the nape sticker S2.

[0089] The nape seal attachment portion 18 may be the same color as or a similar color to the wearer's skin, or may be colorless and transparent. The shape, material, and color of the nape seal attachment portion 18 may be other than those described above. The nape seal attachment portion 18 is preferably located in a position hidden by the rear hair 13j (inside the rear hair 13j) when the hair 20 is down.

[0090] The front part 13a and the nape part 13g are connected by a connector 13h. The connector 13h shown in Fig. 10 includes a band 13k attached to one end of the front part 13a, a loop surface 13m attached to a portion of the outer surface of the band 13k, a hook surface 13n attached to another portion of the outer surface of the band 13k, and a fold-back device 13p attached to the other end of the front part 13a. The nape part 13g is fixed to the inside of the band 13k.

[0091] When using this connecting body 13h, the front part 13a and the nape part 13g are placed on the head, and the band 13k is passed through the folding device 13p and folded back, and the hook surface 13n and the loop surface 13m of the folded band 13k are pressed against each other, thereby connecting the front part 13a and the nape part 13g.

[0092] As shown in Figure 11, an anti-slip band 13r, whose surface in contact with the skin is made of an anti-slip material, can be placed inside the nape part base 13i. The anti-slip band 13r can be made of the same material as the front part 13a or a different material. The anti-slip band 13r can also be integrated with the front part 13a or can be separate. The anti-slip band 13r is provided along the width direction of the inner surface of the nape part 13g and serves to prevent the nape part 13g from slipping from its predetermined position on the head.

[0093] When the anti-slip band 13r is interposed inside the nape part base 13i, for example, the nape part 13g is fixed to the outside of the anti-slip band 13r provided at one end of the front part 13a. A band 13k having a loop surface 13m and a hook surface 13n on its outer surface is fixed to the outer surface of the nape part 13g.

[0094] When using this connector 13h, with the front part 13a and nape part 13g placed on the head, the band 13k is passed through the folding tool 13p and folded back, and the hook surface 13n and the loop surface 13m of the folded back band 13k are pressed against each other, thereby connecting the front part 13a and nape part 13g. The nape part 13g is placed on the head with the anti-slip band 13r facing the skin.

[0095] 10 and 11, if the upper part of the nape part 13g is made to extend above the upper end of the connecting body 13h (more specifically, the band 13k), the band 13k does not touch the head and no step is created, resulting in a good fit. However, the upper end of the nape part 13g can be made flush with the upper end of the band 13k, or it can be positioned lower than the upper end of the band 13k.

[0096] This modified wig 30 can be attached, for example, by the following procedure: (1) Attach the anti-slip parts 13 to the head (FIG. 12(a)). (2) After attaching the anti-slip parts 13 to the head, fix the fixing devices 16 provided on the base 11 in a predetermined position on the anti-slip parts 13 (FIG. 12(b)). (3) After fixing the fixing devices 16 in a predetermined position on the anti-slip parts 13, place the base 11 over the entire head and fix it to the anti-slip parts 13 (FIG. 12(c)). At this time, the front and side portions of the base 11 can be fixed with double-sided tape, adhesive, or the like.

[0097] The sideburn stickers S1 and nape stickers S2 can be attached at any timing during the attachment process (FIGS. 13(a) and 13(b), 14(a) and 14(b)). There are no particular restrictions on the timing of attachment, and for example, the former can be attached after the base 11 (3) is placed over the entire head and fixed to the anti-slip part 13, while the latter can be attached after the anti-slip part 13 (1) is attached to the head.

[0098] A portion of the sideburn sticker S1 can be attached in advance to the sideburn sticker attachment portion 17. Similarly, a portion of the nape sticker S2 can be attached in advance to the nape sticker attachment portion 18.

[0099] When the wig 30 is made up of separate parts, the main body part and the base part, as in this modified example, it is possible to wash or replace each part individually, making it easy to use.

[0100] As in this modification, the wig 30 equipped with the sideburns sticker attachment portion 17 and the nape sticker attachment portion 18 allows for a natural connection between the sideburns and nape of the neck. This allows for an upstyle with the nape of the neck lifted, for example, and is expected to have the effect of increasing the freedom of hair styling.

[0101] (Other Modified Examples) In the above modified example, the fixing device 16 is provided on the base 11 as an example, but the fixing device 16 can also be provided on the anti-slip part 13, or on both the base 11 and the anti-slip part 13.

[0102] In the above-described modified example, the sideburn sticker attachment portion 17 is provided on the base 11 and the nape sticker attachment portion 18 is provided on the anti-slip part 13, but the sideburn sticker attachment portion 17 and the nape sticker attachment portion 18 can also be provided in other locations.

[0103] For example, both the sideburn sticker attachment portion 17 and the nape sticker attachment portion 18 can be provided on the anti-slip part 13. Conversely, both the sideburn sticker attachment portion 17 and the nape sticker attachment portion 18 can be provided on the base 11. The sideburn sticker attachment portion 17 and the nape sticker attachment portion 18 can also be provided on both the base 11 and the anti-slip part 13.

[0104] The sideburn sticker attachment area 17 may be plain and have no markings, or may have a picture or photo of sideburns printed (displayed) similar to the sideburn sticker S1. Similarly, the nape sticker attachment area 18 may be plain and have no markings, or may have a picture or photo of the nape printed (displayed) similar to the nape sticker S2.

[0105] The sideburn sticker attachment portion 17 and nape sticker attachment portion 18 may be provided as needed, and may be omitted if not required.

[0106] 9 and 15, a front hairline sticker attachment section 19 for attaching a front hairline sticker (not shown) can be provided on the base 11 at a position corresponding to the front hairline. The front hairline sticker is a sticker on the surface of which a picture or photograph of the front hairline is printed (displayed), and is used by attaching one part to the front hairline sticker attachment section 19 and the other part to the wearer's forehead.

[0107] There are no particular limitations on the shape of the front hairline sticker attachment portion 19, but it can be rectangular, curved, or any other shape that naturally fits the front hairline. Like the sideburn sticker attachment portion 17 and the nape sticker attachment portion 18, the front hairline sticker attachment portion 19 can be made of a material that makes it easy to attach a front hairline sticker, such as polyurethane, polyurethane-based thermoplastic elastomer, or elastomer. The front hairline sticker attachment portion 19 can be attached to the base 11 by various adhesive means, such as adhesive or adhesive tape.

[0108] The front hairline sticker attachment portion 19 may be the same color as or a similar color to the wearer's skin, or may be colorless and transparent. The shape, material, and color of the front hairline sticker attachment portion 19 may be other than those described above. The front hairline sticker attachment portion 19 is preferably provided in a position hidden by the hair 20 (inside the hair 20).

[0109] The front hairline sticker attachment section 19 may be plain and have no markings, or may have a picture or photo of the front hairline printed on it, similar to the front hairline sticker. The front hairline sticker attachment section 19 may be provided as needed, and may be omitted if not required.

[0110] In the above modified example, the nape part 13g, which is provided at a position corresponding to the nape of the neck, is provided on the anti-slip part 13, but the nape part 13g can also be provided on the main body part (for example, the base 11), in other words, configured as part of the base 11.

[0111] When the nape part 13g is provided on the main part, for example, as shown in Fig. 16, the third protruding part 11c of the base 11 can be made approximately as large as the nape part base 13i, and the hair 20 corresponding to the rear hair 13j can be provided on the second protruding part 11b. The hair 20 can be made of human hair and / or artificial hair, and can be configured by combining multiple human hairs and / or artificial hairs of the same length or different lengths.

[0112] When the nape part 13g is provided on the base 11, the nape part 13g of the non-slip part 13 can be omitted as shown in Fig. 17. When the nape part 13g is provided on the base 11, a nape sticker attachment part 18 similar to the nape sticker attachment part 18 provided on the nape part 13g can be provided on the lower end side of the third protruding part 11c.

[0113] In addition to the above-mentioned modified examples, the wig base 10 can also be configured as shown in Figures 18 and 19. In the wig base 10 shown in Figures 18 and 19, the first protruding portion 11a and the second protruding portion 11b have arc-shaped tips.

[0114] A bendable plate 11e (e.g., a metal plate) is provided inside the first protruding portion 11a and the second protruding portion 11b. The plate 11e can be bent to fit the shape of the wearer's head, providing a comfortable fit.

[0115] A strip-shaped first bag part 11f is provided on the lower end side of the inner surface of the base 11, from the first protruding portion 11a to one end of the third protruding portion 11c. Similarly, a strip-shaped second bag part 11g is attached on the lower end side of the inner surface of the base 11, from the second protruding portion 11b to the other end of the third protruding portion 11c. The first bag part 11f and the second bag part 11g can be made of a different material from the base 11, or can be made of the same material.

[0116] A tape-like first connecting band 11h connected to the first protruding portion 11a is housed inside the first bag part 11f. A first hook 11j is provided at the tip of the first connecting band 11h that passes through the first bag part 11f. Similarly, a tape-like second connecting band 11i connected to the second protruding portion 11b is housed inside the second bag part 11g. A second hook 11k is provided at the tip of the second connecting band 11i that passes through the second bag part 11g.

[0117] A hooking band member 11m is fixed to the lower end of the outer surface of the third protruding portion 11c, and can be engaged with the first hook 11j and the second hook 11k. The hooking band member 11m is provided with a plurality of hooking portions 11n, and the circumference of the wig base 10 can be adjusted by changing the hooking positions of the first hook 11j and the second hook 11k.

[0118] Providing these parts on the inner surface of the base 11 is expected to have the advantage of making these parts less noticeable. However, when these parts are provided on the inner surface of the base 11, since these parts come into direct contact with the skin, it is preferable to cover them with a cover that feels comfortable against the skin as needed.

[0119] Here, an example is given in which the first bag part 11f, the second bag part 11g, the first connecting band 11h, the second connecting band 11i, and the hook strap member 11m are provided on the inner surface of the base 11, but some or all of these parts can also be provided on the outer surface of the base 11.

[0120] The wig base 10 shown in Fig. 18 has a whorl part 12 provided across the entire width of the head. The whorl part 12 can be made of artificial skin, lace, or the like. The whorl part 12 can also be narrower in width than the whorl part 12 in Fig. 18, as shown in Fig. 19. The whorl part 12 can also be a part that includes the parting of the head and the hairline of the front hair in addition to the whorl.

[0121] In the case of this type of wig base 10, the fixing device 16 can be omitted. When the fixing device 16 is omitted, the part that is attached to the back of the head (the nape side or the back of the head side) can be fixed directly to the head with both connecting bands 11h and 11i without being fixed to the non-slip part 13 attached to the head. On the other hand, the part that is attached to the front of the head can be placed over the non-slip part 13 and fixed to the non-slip part 13 with adhesive or double-sided tape or other adhesive means.

[0122] The configurations shown in Figures 18 and 19 are not limited to cases where the anti-slip part 13 is configured as a separate body, but can also be applied to cases where the base 11, whorl part 12, anti-slip part 13 and hair 20 are configured as a single unit (as in the above embodiment).

[0123] In addition to the various configurations described above, the base 11 can also be constructed by combining a seamless mesh material using heat-sealed threads with a different material such as lace. For example, the front portion can be made of lace material and the back portion can be made of a seamless mesh material using heat-sealed threads. In this case, a silicone member or the like can be interposed between the lace material and the seamless mesh material or in the nape area. These materials can be connected by sewing, adhesive, or the like.

[0124] The base 11 configured in this manner can be provided with a size-adjusting member as needed. Examples of size-adjusting members include a first bag part 11f, a second bag part 11g, a first connecting band 11h, a second connecting band 11i, a first hook 11j, a second hook 11k, and a hooking band member 11m shown in Figures 18 and 19, and a member using an elastic cord and the aforementioned pig nose with a lock.

[0125] The base 11 in the above-described embodiment, modified example, and other modified examples can be manufactured using, for example, a stretchable seamless tubular net N. The tubular net N can be made by knitting using the various methods described above, such as plain knitting.

[0126] The tubular net N can be constructed using one of the following types: covering yarn 14 with heat-sealed yarn as the core material 14a, covering yarn 14 with heat-sealed yarn as the covering material 14b, or heat-sealed yarn without the covering material 14b; or it can be constructed using a combination of two or more types.

[0127] Since each yarn has different characteristics, such as a covering yarn 14 with a heat-sealed yarn as the core material 14a having a good texture, and a covering yarn 14 with a heat-sealed yarn as the covering material 14b being easy to melt and mold, it is possible to select and use the yarn that suits the purpose.

[0128] For example, it is conceivable to construct the area around the face, where a good fit is required, with covering yarn 14, which has excellent formability (specifically, covering yarn 14 with heat-sealed yarn as the covering material 14b, or heat-sealed yarn without the covering material 14b), and construct other areas such as the top of the head with a different covering yarn 14, etc.

[0129] The cylindrical net N is preferably sized to completely cover the entire head model M. For example, the size can be appropriately set within the range of about 20 to 80 cm in length, preferably about 30 to 50 cm, and about 10 to 30 cm in circumference (half body), preferably about 15 to 20 cm.

[0130] Both longitudinal ends of the tubular net N are closed, and one end is cut off when manufacturing the wig base 10. There is no restriction on the color of the tubular net N, but it can be the same color all over or can have different colors in parts. In the latter case, for example, the front area can be beige and the back area can be black. The areas to be colored and the colors to be used can be determined appropriately for each wearer.

[0131] The configurations of the parts shown in the above-described embodiments, modifications, and other modifications are merely examples, and their shapes, materials, sizes (thickness, length, thickness, etc.), installation positions, etc. are not limited to those explicitly described in this application. In addition to the matters explicitly described in this application, all design changes that a person skilled in the art could conceive of from the matters explicitly described are within the technical scope of the present invention.

[0132] Next, a method for manufacturing a wig base of the present invention will be described, taking as an example the case of manufacturing the wig base 10 and the wig 30 of the above-described embodiment (FIGS. 1(a) and 1(b)).

[0133] 20, the wig base 10 and wig 30 of this embodiment can be manufactured through a step S100 of manufacturing a head model M, a step S200 of manufacturing a tubular net N, and a step S300 of manufacturing the wig 30. Note that either the step S100 of manufacturing the head model M or the step S200 of manufacturing the tubular net N may be performed first, or they may be performed in parallel.

[0134] <Step S100 of Producing a Head Model> As shown in FIG. 21 , the head model M can be produced through step S101 of measuring the head shape of the wearer using a three-dimensional measuring machine (a so-called 3D scanner), and step S102 of producing the head model M using a three-dimensional modeling machine (a so-called 3D printer) based on the measured head shape of the wearer.

[0135] - Step S101 of measuring the head shape - In step S101 of measuring the head shape, a three-dimensional measuring machine is used to measure the three-dimensional shape of the part of the wearer above the neck (hereinafter referred to as "head"). An existing 3D scanner or the like can be used as the three-dimensional measuring machine. The three-dimensional measuring machine may be either a contact type or a non-contact type. Examples of head images measured with the three-dimensional measuring machine are shown in Figures 22(a) and 22(b).

[0136] Until now, in order to have a wig made, it was necessary to go to a wig manufacturer's salon and have the shape of the head measured. However, these types of salons are often concentrated in urban areas, which was a major burden for people living in rural areas. In this regard, if a 3D measuring machine is used to measure the head shape, measurements can be made remotely, making it easier to receive orders from people living in rural areas or overseas through online sites, etc.

[0137] In the head model producing step S102, a three-dimensional head model M is produced using a three-dimensional modeling machine from head image data obtained by measurement with a three-dimensional measuring machine. It is preferable to use head image data that has been processed by software, such as by restoring the shape, removing unnecessary parts (noise), and converting it to mesh data.

[0138] The three-dimensional modeling machine can be an existing 3D printer, etc. 3D printers that employ various methods, such as powder sintering additive manufacturing, photolithography, inkjet printing, and inkjet powder additive manufacturing, can be used. An example of a head model M produced by a three-dimensional modeling machine is shown in Figures 23(a) and 23(b).

[0139] It is also possible to use a head model M that is hollow and has through holes H, as shown in Figure 24. The through holes H are holes that allow air and heat to pass through easily. The number, size, arrangement, etc. of the through holes H can be set as appropriate.

[0140] The head model M can be produced using a three-dimensional cutting machine as well as a three-dimensional molding machine. When a three-dimensional cutting machine is used to produce the head model M, the material of the head model M is cut based on head image data obtained by measurement with a three-dimensional measuring machine, and a solid three-dimensional head model M is produced (S102a).

[0141] The solid head model M can be used as is, but if it is to be hollow and provided with a through hole H, the inside of the solid head model M is hollowed out and the through hole H is opened in the head (S103).

[0142] In this embodiment, an example is taken of a case where a head model M of the entire head including the face is produced using a three-dimensional modeling machine or a three-dimensional cutting machine. However, as shown in FIG. 25 , it is also possible to produce only a part of the head model M (hereinafter referred to as a "model part") M2 using a three-dimensional modeling machine or a three-dimensional cutting machine, and then place the model part M2 on a head base M1, which serves as a base, to form the head model M.

[0143] For example, a head base M1 in the shape of a head (the entire head including the face) can be produced, and a model part M2 of the head excluding the face can be produced using a three-dimensional modeling machine, and the model part M2 can be placed on the head base M1 to create the head model M. In this case, the head base M1 can be produced using a cheaper material than that used in the three-dimensional modeling machine, thereby reducing production costs.

[0144] As in the case where the head model M is produced using a three-dimensional modeling machine, when the head model M is constructed using the head base M1 and model parts M2, the head base M1 can be hollow and have through holes H formed therein.

[0145] The model part M2 may also be provided with a similar through-hole H. In this case, it is preferable to align the through-hole H of the head base M1 and the through-hole H of the model part M2 so that they communicate with each other in whole or in part.

[0146] <Step S200 of manufacturing a cylindrical net> Next, a description will be given of the step of manufacturing the cylindrical net N. In this step, a cylindrical net N large enough to cover the entire head is manufactured using covering yarn 14, in which the outer periphery of core material 14a is covered with covering material 14b. The covering yarn 14 may be the one described above.

[0147] The cylindrical net N can be produced by knitting using plain knitting, rib knitting, purl knitting, thermal knitting, pique knitting, reversible pique knitting, smooth knitting, reverse pile knitting, jacquard knitting, intarsia knitting, etc. A seamless knitting machine or the like can be used to produce the cylindrical net N.

[0148] An example of a manufactured cylindrical net N is shown in Figure 26. The upper part of the cylindrical net N is shaped to fit snugly against the head, making it easy to fit to the head. An opening N1 is provided at the bottom of the cylindrical net N, so that the cylindrical net N can be placed over the head model M through the opening N1.

[0149] <Step S300 of Making a Wig> Next, we will explain the steps of making the wig 30. As shown in Figure 27, the wig 30 can be manufactured through step S301 of forming the tubular net N, step S302 of providing the slip-prevention parts 13, step S303 of cutting the tubular net N, step S304 of providing the whorl parts, step S305 of tying the hair 20, and step S306 of providing the adjuster 15.

[0150] - Step S301 of forming the cylindrical net - In step S301 of forming the cylindrical net N, the cylindrical net N is placed over the head model M from the top side so as to cover the entire head model M, and the cylindrical net N is heated to form the cylindrical net N into a shape that conforms to the head model M.

[0151] The cylindrical net N can be heated by various methods, for example, using a heated liquid. The liquid can be, for example, water (e.g., water at a temperature of approximately 70 to 180°C, preferably approximately 80 to 100°C), or any other liquid of various compositions that does not react with and degrade the material of the cylindrical net N. In this case, the liquid need only be in a liquid state during the heat treatment. Furthermore, heating can also be performed using methods such as steam (including superheated steam), iron heating, microwave irradiation, and ultrasonic irradiation. The temperature and heating time vary depending on the material of the covering yarn 14, but should be set to a temperature (required melting temperature) and time (required melting time) at which the core material 14a of the covering yarn 14 melts.

[0152] In this embodiment, a head model M is used that is hollow and has through holes H. Since heated liquid, air (including steam), etc. pass through the through holes H, the temperature is easily transmitted from the inside of the cylindrical net N, and the entire cylindrical net N can be heated evenly and uniformly.

[0153] Furthermore, when the head model M covered with the cylindrical net N is immersed in heated liquid, the head model M having the through holes H is used, which makes it difficult for the head model M covered with the cylindrical net N to float up, and the entire cylindrical net N can be reliably heated.

[0154] In cases where the cylindrical net N is heated while boiling water, the bubbles (water vapor) that form during boiling tend to cause the head model M to float up, but when a head model M equipped with through holes H is used, the water vapor escapes through the through holes H, making it difficult for the head model M to float up, and the cylindrical net N placed over the head model M can be kept submerged, ensuring reliable heating of the entire cylindrical net N.

[0155] Furthermore, in a head model M with through holes H, heat is less likely to build up in the head model M itself than in a solid head model M, and the risk of the head model M cracking or breaking due to the application of heat can be reduced.

[0156] In addition, when heating the tubular net N using liquid, in addition to the method of heating the liquid placed in a container and immersing the tubular net N, it is also possible to heat the tubular net N by pouring heated liquid over it or by immersing the tubular net N in boiling liquid.

[0157] - Step S302 of providing slip prevention parts - In step S302 of providing slip prevention parts 13, slip prevention parts 13 formed in a ring shape are adhered to the outer periphery (inner periphery when worn) of the tubular net N. The slip prevention parts 13 described above can be used. The slip prevention parts 13 can be attached to the tubular net N by crimping, sewing, or other methods.

[0158] - Step S303 of Cutting Cylindrical Net - In step S303 of cutting the cylindrical net N, the excess portion of the cylindrical net N provided with the slippage prevention parts 13 is cut off and formed into the shape of a cap (to obtain the cap-shaped base portion 11).

[0159] Specifically, the tubular net N is cut away from the areas covering the forehead, top, both sides of the head, and the back of the head. At this time, the area around the ears is cut away so that both ears are exposed. The area to be cut away can be determined by determining the optimal position for each wearer.

[0160] Preferably, after cutting the cylindrical net N, the cut portion is folded back and stitched, etc. If the first bag part 11f, the second bag part 11g, the first connecting band 11h, the second connecting band 11i, the first hook 11j, etc. shown in Figures 18 and 19 are to be attached, this can be done during this process.

[0161] -Step S304 of providing the whorl part- In step S304 of providing the whorl part 12, the whorl part 12 is provided at the top of the cap-shaped base 11. The whorl part 12 can be any of those described above. The whorl part 12 can be attached to the base 11 by crimping, sewing, or other methods. The whorl part 12 may be provided at a different time; for example, it can be implanted before the slip-prevention part 13 is provided.

[0162] - Step S305 of implanting hair - In step S305 of implanting hair 20, hair 20 is implanted in base 11 obtained by cutting into a cap shape. The implantation of hair 20 can be performed by the method described above. Note that the timing of implanting hair may be other than this, and for example, hair may be implanted before the anti-slip part 13 is provided.

[0163] In step S306 of installing the adjuster 15 on the slip-prevention part 13, a notch is made in the slip-prevention part 13 at a position behind the ear, and the adjuster 15 is attached to the notch. The adjuster 15 may be a combination of the aforementioned locking pig nose and string material, or another one.

[0164] The manufacturing method of the wig base 10 and the wig 30 described here is one example, and the manufacturing method of the wig base 10 and the wig 30 of the present invention is not limited to the method of this embodiment. The manufacturing method of the wig base 10 and the wig 30 of the present invention can be modified by adding, omitting, or replacing steps within the scope that can achieve the intended purpose.

[0165] For example, in the example described above, step S305 of tying the hair 20 is performed after step S304 of providing the whorl part 12, but step S304 of providing the whorl part 12 can also be performed after step S305 of tying the hair 20. Also, step S306 of providing the adjuster 15 may be performed before or after step S302 of providing the slippage prevention part 13.

[0166] Furthermore, in the above-mentioned example, step S305 of implanting hair 20 is performed after step S303 of cutting the tubular net N, but step S305 of implanting hair 20 can also be performed prior to step S302 of providing anti-slip parts 13, step S303 of cutting the tubular net N, and step S304 of providing whorl parts 12, in other words, after step S301 of forming the tubular net N.

[0167] For example, in the example described above, the step S305 of tying the hair 20 is performed after the step S304 of providing the whorl part 12, but the opposite can also be done: the step S304 of tying the hair 20 is performed after the step S305 of tying the hair 20. The order of the production steps described here is an example, and the steps can be interchanged as appropriate.

[0168] In addition, if the anti-slip parts 13 are parts (for example, front parts 13a and back parts 13b) manufactured by outputting shape memory polymer using a 3D printer, the wig base 10 and wig 30 can be manufactured using the following procedure.

[0169] First, a cylindrical net N is placed over the head model M from the top side so as to cover the entire head model M, and the cylindrical net N is heated to form the cylindrical net N into a shape that conforms to the head model M (FIG. 28(a)). Next, hair 20 is implanted into the cylindrical net N (FIG. 28(b)). After implantation, the cylindrical net N is turned inside out and placed over the head model M (FIG. 28(c)).

[0170] The front part 13a and the back part 13b, which have been preheated and softened, are set on the inverted cylindrical net N (Figure 29(a)), and the ring-shaped part 13c is placed on the upper side (the side facing the wearer's skin) of the front part 13a and the back part 13b (Figure 29(b)).

[0171] Thereafter, the cylindrical net N on which the front part 13a, back part 13b, and ring-shaped part 13c are set, and the head model M are set in a case Y connected to a high-temperature steam generator X. In this state, high-temperature steam is supplied into the case Y from the high-temperature steam generator X, while the inside of the case Y is suctioned by a suction device Z, so that the front part 13a, back part 13b, and ring-shaped part 13c are tightly attached to the cylindrical net N (FIG. 29(c)).

[0172] Thereafter, the process of cutting off the excess portion of the cylindrical net N, attaching the whorl part 12, attaching the adjuster 15, etc. is carried out, and the wig 30 is completed.

[0173] By suction in a high-temperature steam environment and subsequent cooling, the front part 13a and the back part 13b are shaped to fit the head model M. However, if the fit is uncomfortable, the front part 13a and the back part 13b can be heated with a hair dryer or the like to be molded into a shape that fits the head model M (FIG. 30).

[0174] As a modified example, the wig 30 shown in Figure 8 can be manufactured, for example, through a process of manufacturing a part (main part) having a base 11, a whorl part 12, and hair 20, and a process of manufacturing a slip-prevention part 13 (base part).

[0175] - Manufacturing process of part including base, whorl part, and hair - The part including base 11, whorl part 12, and hair 20 can be manufactured through, for example, step S301 of forming the cylindrical net N, step S303 of cutting the cylindrical net N, step S304 of providing the whorl part 12, and step S305 of tying the hair 20. Each step has already been explained, so explanations will be omitted.

[0176] In the manufacturing process of the part including the base 11, the whorl part 12 and the hair 20, the sideburn sticker attachment part 17 and the fixing device 16 described above are provided on the base 11 as needed.

[0177] As with the step S300 of producing the wig 30, the step S305 of tying the hair 20 can be carried out prior to the step S303 of cutting the cylindrical net N and the step S304 of providing the whorl part 12, in other words, after the step S301 of forming the cylindrical net N. In addition, in the step S304 of providing the whorl part 12, a hairline lace part can also be attached.

[0178] --Manufacturing Process of the Anti-Slip Part-- In the manufacturing process of the anti-slip part 13, the connector 13h is attached to the front part 13a and nape part 13g, which have been prepared in advance. The nape part 13g is provided with rear hair 13j and a nape sticker attachment part 18, either beforehand or afterwards. The rear hair 13j can be planted in the nape part base 13i, or it can be attached to the surface of the nape part base 13i by sewing, gluing, or other methods.

[0179] The embodiments and modifications, as well as the manufacturing methods and manufacturing steps described so far, are merely examples, and the wig base 10, wig 30, and wig base manufacturing method of the present invention are not limited to the configurations of the above-described embodiments, etc. The wig base 10, wig 30, and wig base manufacturing method of the present invention can be modified as appropriate, such as by adding, replacing, or omitting components, within the scope of achieving the intended purpose.

[0180] Furthermore, the configurations of the above-mentioned embodiment and the modified examples can be added or replaced with each other. For example, the base 11 of the wig base 10 of the above-mentioned embodiment can be provided with the sideburn sticker attachment part 17 described in the modified example, and the anti-slip part 13 of the above-mentioned embodiment can be provided with the nape sticker attachment part 18 described in the modified example.

[0181] The embodiments, modifications, and manufacturing methods disclosed herein are merely examples and are not intended to limit the scope of the present invention. The technical scope of the present invention is defined by the claims. The technical scope of the present invention also includes equivalents to the claims.

[0182] - Experiment 1 - The applicant conducted the following experiment (hereinafter referred to as "Experiment 1") to verify the texture, shape stability, and ease of molding depending on the material. The outline and results of Experiment 1 are as follows.

[0183] [Outline of Experiment 1] In Experiment 1, four types of seamless knit wig bases, Examples 1 to 4, listed in Table 1 below, were prepared and evaluated for "texture," "shape stability," and "ease of molding." The evaluation was conducted on a five-point scale.

[0184] After molding, the "feel" was evaluated by skilled workers engaged in wig development, etc., who compared the appearance of fluffiness, fraying, smoothness, and suppleness, rating the fabric on a five-point scale, with a rating of "5" indicating that the feel was the same as that of ordinary nylon fiber itself and a rating of "1" indicating that the feel after heat molding was so poor that it was unsuitable for sale.

[0185] For the evaluation of "shape stability," the wig bases were washed in accordance with JIS L1930 C4N after molding, and then dried. Experienced workers engaged in wig development, etc. visually compared the appearance smoothness, shape retention, and dimensional change rate of the wig bases, and rated on a 5-point scale, with "5" indicating that the wig base was able to maintain the same shape as the wig base before washing, and "1" indicating that the wig base was not able to maintain the same shape as the wig base made from ordinary nylon fiber.

[0186] The evaluation of "ease of molding" is an evaluation of the molding process when manufacturing the wig base. The molding process for the wig bases of Examples 1 to 4 was all carried out manually by heating the seamless knitted fabric attached to a head model with an iron. Experienced workers engaged in wig development, etc., compared the ease of ironing, ease of deformation, and ease of hardening for this molding process, and evaluated it on a 5-point scale, with "5" being equivalent to the ease of molding with heat-fused yarn itself and "1" being impossible to mold.

[0187] Table 1 shows a comparison of the covering yarns used in each wig base of Examples 1 to 4.

[0188] The covering yarn used for the wig base of Example 1 is a double covering yarn using 100 denier Flor (registered trademark) as the core material and 70 denier nylon as the covering material. In Tables 1 and 2, denier, which is the unit of measurement for fineness (fiber thickness), is indicated as "d."

[0189] The covering yarn used for the wig base of Example 2 is a double covering yarn using 50 denier Joiner (registered trademark) as the core material and 70 denier nylon as the covering material.

[0190] The covering yarn used for the wig base of Example 3 is a single covering yarn using 70 denier nylon ply and twisted as the core material and 50 denier joiner as the covering material.

[0191] The covering yarn used for the wig base of Example 4 is a single covering yarn with polyurethane as the core material and 70 denier nylon and 50 denier joiner as the covering materials. The two types of covering materials are top twisted for the former and bottom twisted for the latter.

[0192] [Results of Experiment 1] Table 2 shows the evaluation results of each wig base regarding "feel," "shape stability," and "ease of molding."

[0193] As shown in Table 2, for "feel," Example 1 received a score of "5" and Example 2 a score of "4," while Examples 3 and 4 received scores of "3" or "2." Examples 1 and 2 used covered yarns in which the outer periphery of the heat-fusible yarn was covered with a covering material. This confirmed that covering the outer periphery of the heat-fusible yarn with a covering material, as in Examples 1 and 2, improved the feel (touch).

[0194] For "shape stability", Example 1 was rated "4", Examples 2 and 3 were rated "3", and Example 4 was rated "2".

[0195] Regarding "ease of molding," Example 1 was rated "4," Examples 2 and 3 were rated "3," and Example 4 was rated "2." As can be seen from these examples, by using heat-sealed yarn for the core material and covering it with a covering material, it is possible to improve the texture while maintaining the shape stability and ease of molding obtained from the heat-sealed yarn. On the other hand, although no difference is observed here because strong iron heating is performed, when heat-sealed yarn is used for the covering material rather than the core material, as in Examples 3 and 4, molding can be easily performed without heat being transferred to the center of the core material.

[0196] Naturally, if heat-sealing yarn is not used, shape memory cannot be achieved even with molding. Therefore, for example, if nylon 70d is used for both the core material and the covering material, the "shape stability" will be "1" and the "ease of molding" will also be "1." All of Examples 1 to 4 use a combination of nylon fiber, a common synthetic fiber, and heat-sealing yarn, making it possible to provide a wig base that combines a certain level of texture and shape stability.

[0197] - Experiment 2 - The applicant of the present invention conducted an experiment (hereinafter referred to as "Experiment 2") to confirm molding using heated water. The outline and results of Experiment 2 are as follows.

[0198] [Summary of Experiment 2] A wig base was made using double covering yarn with 100 denier flor as the core material and 70 denier nylon as the covering material, and the wig base was placed on a head model (in Experiment 2, a substitute head model was used instead of one created with a 3D printer), and the wig base was immersed in hot water at a temperature of 80°C (water temperature) and heated. The immersion time was 20 minutes. After immersion, the wig base was removed from the head model to check whether it could maintain its shape.

[0199] As a result, it was confirmed that the shape of the wig base remained stable even after it was removed from the head model, and that the shape was maintained after natural cooling.

[0200] The present invention can be particularly suitably used as a wig base 10 for a full head, a wig 30 for a full head, and a method for manufacturing a wig base 10 for a full head.
