The knitting yarn may include a natural material. The knitting yarn may include at least one of vegetable fiber and animal fiber. The knitting yarn may include any of cotton, silk, and wool. The connecting yarn may be a polyamide resin monofilament. The connecting yarn may be thinner than the knitting yarn. The wig may be provided with an edge portion formed of a material different from that of the base portion at least at a part around the base portion. The edge portion may be coupled to the base portion by an adhesive tape including a base material coated with a pressure-sensitive adhesive.

The above summary of the invention does not enumerate all the features of the present invention. A sub-combination of these feature groups can also be an invention.

It is a schematic diagram of the wig 100 whole. 2 is a partially enlarged view of a base part 200. FIG. It is a schematic diagram which shows the method of knitting the base part. It is a schematic diagram which shows the other knitting method of the base part 201. FIG. 3 is a partially enlarged view of a base unit 500. FIG.

Hereinafter, the present invention will be described through embodiments of the invention. However, the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention.

FIG. 1 is a schematic diagram of the wig 100 as a whole. The wig 100 includes a base portion 200, an edge portion 300, and hair 400. The wig 100 is used by being worn on the head 91 by the user 90 as shown.

The base part 200 of the wig 100 is formed of a knitted fabric and occupies most of the wig 100. When the user 90 wears the wig 100, the base unit 200 covers at least a part of the head 91 of the user 90. The wig 100 may be a full wig that covers the entire head 91 or a partial wig that covers a part of the head 91.

Since the knitted fabric forming the base portion 200 has high stretchability, when the wig 100 is worn, the base portion 200 closely adheres along the shape of the head 91 of the user 90. Further, since the knit fabric has air permeability, even if it is in close contact with the head 91, the user 90 is not uncomfortable.

The edge portion 300 is disposed on the periphery of the base portion 200, protects the outer edge of the base portion 200, and closely contacts the edge of the base portion 200 with the head of the user 90. For this reason, the edge part 300 may be given a stretchability stronger than that of the base part 200. Further, the inner surface of the edge portion 300 may be formed in a shape that does not slip easily, or a material that does not slip easily may be used for the edge portion 300.

In addition, the edge part 300 may be provided in the whole edge of the wig 100, and may be provided partially. Further, the edge portion 300 may be omitted at all. When an adhesive or the like is used for mounting the wig 100, at least a part of the edge portion 300 may be formed of a material having high adhesiveness to the adhesive.

The hair 400 is attached to the knitted fabric of the base part 200. Thereby, when the user 90 wears the wig 100, the hair 400 appears to grow from the head 91 of the user 90. Hair 400 may be natural hair or artificial hair.

In the wig 100 described above, the edge portion 300 and the base portion 200 may be joined by an adhesive tape instead of sewing. In this case, an adhesive tape obtained by applying a pressure-sensitive adhesive to a base material having elasticity equivalent to that of either the edge part 300 or the base part 200 may be used. Moreover, you may use the same raw material as the edge part 300 or the base part 200 as a base material of an adhesive tape.

By using such an adhesive tape on the surface of the wig 100 that does not touch the skin of the user 90, that is, the outer surface of the wig 100, the user 90 feels uncomfortable with respect to the joint portion of the edge portion 300 and the base portion 200. The wig 100 which does not feel can be formed.

In addition, you may use the coupling | bonding of the fabric by an adhesive tape besides the coupling | bonding of the base part 200 and the edge part 300. FIG. For example, when the base part 200 is formed into a shape that follows the shape of the head of the user 90, an adhesive tape may be used instead of sewing. Moreover, when the wig 100 has the area | region which does not implant the hair 400 other than the base part 200 and the edge part 300 which implant the hair 400, the base part 200 and the fabric which makes a non-implanted part are bonded with an adhesive tape. May be combined.

FIG. 2 is an enlarged view showing a part of the base portion 200 indicated by A in FIG. The knitted fabric forming the base portion 200 has a weft yarn 210 and a warp yarn 220.

The weft yarn 210 forms a plurality of loops each of which forms an arcuate curve, and extends in the horizontal direction in the figure. Each of the weft yarns 210 extending in the horizontal direction is called a course. Therefore, in the following description, the course extension direction is described as the course direction.

The loops formed in each of the weft yarns 210 form a knitted fabric that expands in a plane along the plane of the paper by being sequentially submerged in the adjacent loops in the figure. That is, the weft yarn 210 in this embodiment is an example of a knitting yarn that forms a weft knit.

Furthermore, the illustrated knit fabric has warp yarns 220 that connect the weft yarns 210 adjacent to each other in the longitudinal direction in the figure. The warp yarn 220 extends in a direction intersecting with the weft yarn 210, and is wound around the weft yarn 210 every time it intersects with the weft yarn 210 to connect the loop formed by the weft yarn 210. The warp yarn 220 in this embodiment is an example of a connecting yarn forming a weft knit.

Here, a plurality of rows of loops arranged in the longitudinal direction in the figure where one warp thread 220 is connected is called a wale. Therefore, in the following description, the arrangement of loops in the wale is referred to as a wale row, and the arrangement direction of the loop is referred to as a wale direction.

In the knitted fabric of the base portion 200, the warp yarn 220 circulates around the weft yarn 210 and restrains the weft yarn 210. Thereby, when tension | tensile_strength acts on a part of weft thread 210, the displacement to the horizontal direction in the figure of the weft thread 210 is latched. By such connection by the warp yarns 220, the illustrated base portion 200 suppresses the occurrence of fraying that tends to occur in the knit fabric.

In the wig 100, the hair 400 is attached to the base part 200 by pulling up one of the wefts 210 and connecting them. When any one of the weft yarns 210 is pulled in the step of attaching the hair 400 as described above, in the base portion 200, the weft yarn 210 is pulled out by the warp yarn 220 as described above. No fraying occurs.

In the knitted fabric forming the base portion 200, natural materials derived from plants or animals can be suitably used as the weft 210. More specifically, plant-derived materials such as silk, cotton and wool, and animal-derived materials such as wool and cashmere can be preferably used as filaments or twisted yarns. By using this kind of natural material, the wig 100 can be comfortably worn, and can be suitably used particularly for medical wigs that are forced to wear the wig 100 regardless of the user's preference.

Moreover, as the warp yarn 220 of the knitted fabric forming the base portion 200, monofilaments of polyester and polyamide resin can be preferably used. This type of chemical fiber is excellent in dimensional stability and shape stability.

The warp yarn 220 of chemical fiber may be made thinner than the weft yarn 210 of natural material. Thereby, in the whole base part 200, the touch of the weft 210 becomes dominant for the user 90, and the comfort of the weft 210 and the functionality of the warp 220 can be compatible.

FIG. 3 is a schematic diagram showing how to knit the knitted fabric forming the base portion 200 shown in FIG. In the illustrated example, four courses of

weft yarns

211, 212, 213, and 214 supplied from the yarn feeders 1 to 4 are weft knitted to knit the knitted fabric.

Further, the warp yarn 220 is supplied so as to intersect with the

weft yarns

211, 212, 213, 214 forming the knitted fabric by weft knitting, and each time the

weft yarns

211, 212, 213, 214 intersect, a needle for knitting the warp yarn 220 is added. Alternately forward or backward. As a result, the warp yarn 220 is wound around each of the adjacent loops in the direction of one wale row.

The displacement of the weft yarn 210 wound with the warp yarn 220 in the direction intersecting the warp yarn 220 is locked. Therefore, in the knitted base portion 200, the loops in the respective wales are sequentially connected to form the structure shown in FIG.

FIG. 4 is a schematic diagram showing another example of how to knit other knit fabric forming the base portion 201. In the illustrated example, five courses of

weft yarns

211, 212, 213, 214, and 215 supplied from the yarn feeders 1 to 5 are weft knitted to knit the knitted fabric. Further, the warp yarn 220 is supplied so as to intersect with the

weft yarns

211, 212, 213, 214, 215 forming the knit fabric by weft knitting, and every time the

weft yarns

211, 212, 213, 214, 215 intersect, It is wound around the

weft

211, 212, 213, 214, 215.

Here, in the example shown in FIG. 5, the needle forward feed and the backward feed are switched after being continuously performed twice. Thereby, after the warp yarn 220 is wound around one loop belonging to one wale and then wound around the weft yarn 210 of the next course belonging to the same wale, the warp yarn 220 belongs to another adjacent wale and is next adjacent. Repeatedly repeats the case of being wound around a loop belonging to the course to be performed.

In this way, in the knitted base portion 201, a connecting portion in which loops adjacent in the wale direction are connected and a connecting portion in which loops displaced in both the wale direction and the course direction are connected are distributed throughout the base. The fraying of the part 201 is prevented.

The wig 100 can be formed using the

base parts

200 and 201 knit fabric knitted by any of the methods shown in FIGS. Further, in the wig 100 including any of the

base portions

200 and 201, the loop formed by the weft yarn 210 or the warp yarn 220 is connected to the other loops, so that fraying is maintained while maintaining the stretchability as a knit fabric. It is preventing. Thereby, since the hair 400 can be easily attached without damaging the

base parts

200 and 201, the productivity of the wig 100 can be factoryized.

In addition, with the above structure, even when natural materials that are weak to the base are used as the materials of the

base portions

200 and 201, it is possible to reduce the cost by manufacturing the factory while maintaining the quality. Thereby, in the wig 100 for medical use especially, a user's convenience and comfort can be improved.

FIG. 5 is a partially enlarged view of a base unit 500 according to another example. The illustrated base portion 500 is a warp knitted fabric knitted with a plurality of warp yarns 520. Therefore, in this embodiment, the warp yarn 520 is an example of a knitting yarn.

Furthermore, the base portion 500 has a weft yarn 510 that connects the warp yarns 520 arranged in the course direction. In this embodiment, the weft yarn 510 is an example of a connecting yarn.

The structure as described above stops the warp yarn 520 from being significantly displaced in the longitudinal direction in the figure even when a portion of any of the warp yarns 520 is pulled. As a result, fraying of the knitting yarn is prevented even in the base portion 500 formed of the warp knitted fabric.

As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above-described embodiment. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.
