Description

  The present invention relates to a wig, and more particularly to a wig using an artificial hair material made of a synthetic fiber.

  Conventionally, wigs using human hair are widely known. Such wigs are very expensive, although a natural appearance is obtained when worn. On the other hand, artificial hair materials made of synthetic fibers such as polyester and polyvinyl chloride, which are cheaper than human hair, are also known as hair materials used in wigs. Such artificial hair material may be too glossy compared to human hair, and in such a case, gloss reduction processing is performed. For example, Patent Document 1 discloses that an artificial hair material made of synthetic fiber is subjected to alkali treatment to form irregularities on the surface thereof, thereby reducing gloss.

JP 2004-162195 A

  In the gloss reduction process described in Patent Document 1, there is a limit to gloss reduction. That is, in the reduction treatment, it is difficult to make the artificial hair material made of synthetic fiber gloss similar to the hair quality of the user who suffers from a reduction in the amount of hair.

  An object of the present invention is to provide a wig having gloss similar to that of human hair while using an artificial hair material made of synthetic fibers that is cheaper than human hair.

  In order to solve the above problems, the present inventors have reduced the gloss effectively because the light hitting the swelled hair is irregularly reflected in the swelled hair having a shape in which a plurality of ridges and valleys are alternately arranged. I found out.

  Accordingly, the present invention is a wig having a plurality of artificial hair materials each made of a synthetic fiber, wherein the plurality of artificial hair materials have a shape in which a plurality of straight hairs, peaks and valleys are alternately arranged. A wig including swell hair is provided.

  In the present invention, since the plurality of artificial hair materials include undulating hairs having a shape in which a plurality of peaks and valleys are alternately arranged, the gloss is effectively reduced. Specifically, straight hair reflects light that hits the straight hair in a substantially constant direction, whereas swelled hair has a shape in which a plurality of peaks and valleys are alternately arranged. The light that hits the light is irregularly reflected. Therefore, by including undulating hair, the luster is visually reduced as compared with the case where all the hair materials of the plurality of artificial hair materials are straight hair. Furthermore, by using the wig using the undulating hair, it becomes closer to the user's hair quality and a natural appearance can be obtained. The straight hair includes not only those having a shape extending substantially linearly but also those having a shape that curves so as to have only a single peak.

  In this case, it is preferable that the ratio of the number of the undulating hairs when the whole of the plurality of artificial hair materials used in the wig is 1 is 0.1 to 0.6.

  In this way, the gloss is more reliably reduced and the appearance is closer to human hair. Specifically, the gloss is more reliably reduced by setting the ratio of the number of undulation hairs to 0.1 or more, and further, the ratio of the number of undulation hairs is relatively reduced to 0.6 or less. Suppresses the appearance of unnatural appearance compared to the appearance of human hair due to an increase in the amount of undulating hair, that is, the undulating hair is conspicuous and the overall unit of the artificial hair material is reduced. Is done.

  In the present invention, the undulating hair is a mold having a shape capable of forming the crest and the trough by sandwiching the straight hair from both sides in the radial direction perpendicular to the longitudinal direction. Is preferably formed by heating the straight hair while sandwiching the wire from both sides in the radial direction.

  In this way, uniform waviness can be formed from straight hair in a relatively short time and easily. Specifically, by sandwiching straight hair between the molds and heating the straight hair, the straight hair is softened and formed into a shape in which a plurality of ridges and valleys are alternately arranged. Waviness is formed in a shorter time than when heating is not performed.

  As described above, according to the present invention, it is possible to provide a wig having a gloss similar to that of human hair while using an artificial hair material made of synthetic fiber that is less expensive than human hair.

It is the schematic of the wig of one Embodiment of this invention. It is the schematic of the waviness shown in FIG. It is the schematic which shows the manufacturing method of waviness. It is a graph which shows the relationship between the ratio of the number of waviness, and a gross value.

  A wig according to an embodiment of the present invention will be described with reference to FIGS.

  As shown in FIG. 1, the wig of this embodiment includes a wig base 10 and a plurality of artificial hair materials 20 attached to the wig base 10 by planting or sewing, and each made of synthetic fibers. ing. In this embodiment, the artificial hair material is formed of fibers made of polyester. However, the synthetic fiber used for the artificial hair material is not limited to a fiber made of polyester. For example, artificial hair materials include polyvinyl chloride synthetic fibers, polyacrylonitrile synthetic fibers such as polyacrylonitrile and modacrylic, polyolefin synthetic fibers such as polyethylene, polypropylene, polybutylene or polystyrene, polyamide synthetic fibers such as nylon, and polyvinyl alcohol. A synthetic fiber, a polyvinylidene chloride synthetic fiber, a polyether ester synthetic fiber or a polyurethane synthetic fiber, or a fiber made of acetate or the like may be used. In FIG. 1, an example in which a plurality of artificial hair materials 20 are attached to only a part of the wig base 10 is shown, but actually, the plurality of artificial hair materials 20 are spread over the entire area of the wig base 10. It is attached.

  As shown in FIG. 1, the plurality of artificial hair materials 20 includes straight hairs 22 and waviness hairs 24. These straight hairs 22 and waviness hairs 24 are set to substantially the same length.

  As shown in FIG. 2, the wavy hair 24 has a shape in which a plurality of crests 24 a and troughs 24 b are alternately arranged. The wavy hair 24 has a gloss reduction function. Specifically, since the undulation hair 24 has a shape in which a plurality of peak portions 24a and a plurality of valley portions 24b are alternately arranged, the light that hits the undulation hair 24 is irregularly reflected, thereby effectively reducing the gloss. The In the present embodiment, the wavy hair 24 has a peak portion 24a and a valley portion 24b over the entire region in the longitudinal direction. The first distance L between the ridges 24a adjacent to each other in the wavy hair 24 is preferably set to 1.0 mm to 50 mm, and more preferably set to 2.0 mm to 20 mm. In the present embodiment, the crest 24a and the trough 24b are formed so that the first distance L is constant over the entire region in the longitudinal direction. Moreover, it is preferable that the 2nd distance R between the peak part 24a and the trough part 24b about the direction orthogonal to the arrangement direction of the some peak part 24a is set to 0.5 mm-10 mm, 0.5 mm- More preferably, it is set to 5.0 mm.

  Moreover, it is preferable that the ratio of the number of the undulating hairs 24 when the total number of artificial hair materials 20 used in the wig is 1 is set to be larger than 0 and 0.6 or less. This ratio is more preferably set to 0.1 to 0.6, and still more preferably set to 0.2 to 0.5. In the present embodiment, the ratio is set to 0.3.

  The straight hair 22 refers to an artificial hair material other than the wavy hair 24 among the plurality of artificial hair materials 20, and has a shape that is recognized as being substantially linear. For example, the straight hair 22 has a shape extending in a substantially straight line, a shape having a shape that curves very smoothly so as to protrude toward one of the radial directions orthogonal to the longitudinal direction, and a substantially S-shape. And those having a smoothly curved shape.

  Next, an example of a method for producing the swell hair 24 will be described with reference to FIG.

  The wavy hair 24 can be formed by sandwiching the straight hair 22 from both sides in the radial direction perpendicular to the longitudinal direction with a mold and heating the straight hair 22. The mold has a shape capable of forming a plurality of crests 24a and a plurality of troughs 24b by sandwiching the straight hair 22 from both sides in the radial direction. In the example shown in FIG. 3, a pair of external gears 30 that mesh with each other is used as the mold. That is, in the present embodiment, the straight hairs 22 are fed between a pair of external gears 30 rotating in opposite directions, and the straight hairs 22 are heated. Thereby, the straight hair 22 is formed into a shape having a plurality of peak portions 24a and a plurality of valley portions 24b while being softened. In this method, it is possible to form the uniform wavy hair 24 from the straight hair 22 in a short time and easily compared to the case where the straight hair 22 is not heated. The heating temperature of the straight hair 22 is preferably set between 100 ° C and 150 ° C. The first distance L and the second distance R can be appropriately adjusted by adjusting the tooth height, pitch, rotational speed, or heating temperature of each gear.

  As described above, in the wig of the present embodiment, the plurality of artificial hair materials 20 include the wavy hair 24 having a shape in which a plurality of ridges 24a and valleys 24b are alternately arranged, so that gloss is effectively reduced. . Specifically, the straight hair 22 reflects the light hitting the straight hair 22 in a substantially constant direction, while the wavy hair 24 has a shape in which a plurality of peak portions 24a and valley portions 24b are alternately arranged. Therefore, the light hitting the swell hair 24 is irregularly reflected. Therefore, by including the undulating hair 24, the gloss is reduced compared with the case where all the hair materials of the plurality of artificial hair materials 20 are straight hairs 22, and the hair is visually recognized. Furthermore, it is known that waviness increases with age, and in the age when it is desired to use a wig (for example, 30's to 50's), wavy hair is mixed in the ground hair. There are many cases. Therefore, by including the undulating hair 24, it becomes close to the user's hair quality and a more natural appearance can be obtained.

  In addition, it should be thought that the said embodiment disclosed this time is an illustration and restrictive at no points. The scope of the present invention is shown not by the above description of the embodiments but by the scope of claims for patent, and further includes all modifications within the meaning and scope equivalent to the scope of claims for patent.

  For example, in the above-described embodiment, the undulation hair 24 has an example in which a plurality of crests 24a and a plurality of troughs 24b are alternately arranged over the entire area in the longitudinal direction. A plurality of peak portions 24a and a plurality of trough portions 24b may have undulations alternately arranged only in a part in the longitudinal direction. For example, when the wig base 10 is attached to the region including the toothpick in the parietal portion, the undulation portion is a portion in which the bone of the parietal portion (parietal bone) projects laterally in the wearing state of the wig (hereinafter, It is preferably formed in a region straddling the “overhang”. Specifically, the portion of the artificial hair material that straddles the overhang is located at the boundary between the portion where the reflected light of the light hitting the portion is relatively strongly visible and the portion where the reflected light is weakly recognized, This is because it is a part that is clearly visible. For this reason, the swell hair 24 is effectively reduced in gloss by including the swell portion in a region straddling the bulging portion in the longitudinal direction.

  Moreover, in the said embodiment, although the example in which the said 1st distance L was formed uniformly over the whole area of the longitudinal direction was shown for the wavy hair 24, this 1st distance L is not restricted to constant, and it adjoins mutually. The first distances L may be different from each other. In this case, the undulation hair 24 preferably includes 2 to 100 peak portions 24a per 10 cm, and more preferably includes 5 to 50 peak portions 24a.

  In addition, each artificial hair material may be subjected to an alkali treatment for forming irregularities on the surface as necessary.

  Next, an example of the wig of the above embodiment will be described with reference to FIG. FIG. 4 shows the relationship between the ratio of the number of undulating hairs 24 and the gross value of the plurality of artificial hair materials 20 when the number of the plurality of artificial hair materials 20 used in the wig is 1. Specifically, FIG. 4 is a graph showing the transition of the gloss value when the ratio is increased from 0 to 1 by 0.1. In addition, the thing with the said ratio 0 is a comparative example with respect to another Example. Further, the gloss value is a value indicating the amount of reflection when light is applied to the surface of the inspection object (a plurality of artificial hair materials 20 in the present embodiment), and the larger this value, the more glossy. In other words, the smaller this value is, the lower the gloss is. In this example, the gloss value was measured by a color difference meter (manufactured by Konica Minolta, Inc./spectral colorimeter CM-700d / diffuse illumination, 8 ° direction light reception). In this embodiment, the lengths of the straight hairs 22 and the swelled hairs 24 are set to about 30 cm, and the gloss value is changed by changing the ratio so that the total number of artificial hair materials 20 is 4 g (about 230). Measurements were made. In this embodiment, an artificial hair material made of polyester fiber is used.

  As shown in FIG. 4, the gloss value of human hair is 2.81, and the gross value of the plurality of artificial hair materials 20 as a whole increases as the ratio increases. It was confirmed. Moreover, when the ratio of the number of the said waviness hairs 24 is 0.1-0.6, it was confirmed that gloss is reduced more reliably and it becomes the appearance close | similar to human hair. Specifically, when the ratio of the number of undulating hairs is 0.1 or more, the reduction in gloss is more clearly recognized, and when the ratio exceeds 0.6, the gloss value is that of human hair. Although approaching, the amount of the swelled hair 24 is relatively increased, so that the swelled hair 24 is conspicuous and the cohesion of the artificial hair material as a whole is reduced, resulting in an unnatural appearance compared to the appearance of human hair. When the ratio is 0.6 or less, it was confirmed that the appearance of an unnatural appearance as described above is suppressed due to the relatively large amount of the wavy hair 24.
