Description

  The present invention relates to a wig base, and more particularly to a wig base for forming a wig by implanting hair.

  Conventionally, wigs are produced by implanting hair such as natural hair or artificial hair on a wig base such as a net member or artificial skin. For example, a wig base made of artificial skin made of a synthetic resin such as polyurethane is superior in shape stability but poor in breathability compared to a wig base made of a net member. In wigs that require comfort, ensuring air permeability is an important factor. Therefore, for example, as disclosed in FIG. 2 of Patent Document 1 and Patent Document 2, a wig base made of a net member made of a mesh is provided.

Japanese Patent Laid-Open No. 7-229209 Japanese Patent Laid-Open No. 2004-60060

  However, the wig base made of a net member has a relatively elastic resilience, and the hair tends to fall down more easily than natural materials such as artificial skin that can stand up near the root of the implanted hair. It may not be possible to obtain the desired hairstyle.

  Usually, hair is planted by binding to the warp or weft forming the net member. This planting is usually performed manually, and after the hair is wound around the warp or weft, the hair is planted in a certain direction because the hair is pulled in a certain direction to form a knot. It will have directivity to. According to such a planting method, the hairs are regularly arranged in the same direction and converge in the same direction. In particular, when a force from above is applied, the hair may sleep without standing up.

  Therefore, as disclosed in Patent Document 1, a method of irregularly planting a plurality of hairs in the warp and weft forming the net member is also conceivable. According to this method, since the amount of hair implanted on the wig base is larger than that of conventional wigs, the hairs can support each other and the implanted hair rises to some extent. However, such a wig has a problem that it is difficult to obtain a satisfactory wig because the hair amount becomes larger than necessary and the appearance becomes unnatural.

  Further, as disclosed in Patent Document 2, a method of preventing the directivity of hair from being directed in a certain direction by using a plurality of net members having different shapes on one wig base is also conceivable. According to the wig in which the hair is implanted in such a net member, the directivity of the implanted hair is rarely collected in the same direction. However, with such wigs, it is difficult to control the directivity of all or part of the planted hair, and it is difficult to set a satisfactory hairstyle because the hair does not come together. It was.

  In addition, as another problem, when a wig base made of a net member is used for a long period of time, the warp or weft constituting the net member is stretched due to a tensile load generated when the wig is attached / detached daily. There is a tendency for the member to be wrinkled. The wrinkles generated in the net member in this manner cause the shape of the wig base to be distorted. When distortion occurs in the shape of the wig base, problems such as deformation of the wig base and a decrease in fit may occur, and a satisfactory wig cannot be obtained by any of the above-described known methods.

  The present invention has been made in view of the above-mentioned problems, and is a wig base that is entirely or partially made of a net member, which provides a natural sense of volume and is familiar with the wig wearer's own hair and is natural. An object of the present invention is to provide a wig base that provides an appearance and a hairstyle, and is excellent in fit and shape stability.

  In order to achieve the above-mentioned object, the present invention according to claim 1 is a network of net members formed by continuously knitting filaments in a wig base formed entirely or partially by net members. The structure has an arc-shaped part for planting hair, and is knitted by connecting the vicinity of the apex of the arc-shaped part and the left and right ends of the mesh, and a plurality of shape stabilizing yarns are stretched over the mesh opening. The wig base is characterized in that the net member is arranged so that the protruding direction of the arc-shaped portion faces the forehead portion side.

  In order to achieve the above-mentioned object, the present invention described in claim 2 is characterized in that, in the wig base according to claim 1, the center angle of the arcuate portion is 85 ° or more and 155 ° or less. .

  In order to achieve the above-mentioned object, according to the present invention described in claim 3, in the wig base according to claim 1 or 2, the bending resistance of the net member is 15 mm or more and 70 mm or less according to A method of JIS L1096. It is characterized by being.

  In order to achieve the above-mentioned object, the present invention according to claim 4 is the wig base according to any one of claims 1 to 3, wherein two or more shape stabilizing yarns are provided in the opening of the mesh. It is characterized in that it is an even number less than the number and is symmetrically spanned with respect to the center line of the arcuate portion.

  In order to achieve the above-mentioned object, according to the present invention described in claim 5, in the wig base according to any one of claims 1 to 4, the net member has a row of arc-shaped portions of adjacent meshes. It is characterized by being continuously arranged so as to be staggered.

  In order to achieve the above-mentioned object, the present invention according to claim 6 is the wig base according to any one of claims 1 to 4, wherein the net member has a row of arc-shaped portions of adjacent meshes. It is characterized by being continuously knitted so as to be in the same row.

  According to the wig base of the present invention, the directivity of the hair becomes radial by being planted so that the hair end side faces in the protruding direction of the arc-shaped portion forming the mesh structure of the net member, and is implanted in the adjacent mesh. Since it intersects with the hair, the rising of each hair is improved, and there is an effect that a natural volume feeling and a hairstyle that are not found in conventional wigs can be obtained.

  Also, in the vicinity of the back of the head, since the directivity of the hair becomes one direction by being planted so that the hair end side faces in the direction opposite to the protruding direction of the arcuate portion, each hair easily overlaps and is more than necessary. The wig's hair and the wearer's own hair become more familiar at the outer edge of the wig, and the familiarity of the nape is particularly familiar, and a natural appearance and hairstyle can be obtained. is there.

  In addition, since the shape stabilizing yarn is arranged at the opening of the mesh, it is possible to improve the tensile strength while maintaining a soft and high fit to the net member, and reduce the strain of the net member that occurs when the wig is attached and detached. There is an effect that it is possible to obtain the shape stability of the wig base not found in the wig.

It is a top view of the wig which uses one Embodiment of the wig base which concerns on this invention. It is the schematic diagram showing the organization of the network of this invention. (A) is an enlarged view of 1st Embodiment of a net member, (b) is an enlarged view of 2nd Embodiment of a net member. (A) is a figure which shows the directivity of the hair planted in the protrusion direction of the arc-shaped part of a net member, (b) is the directivity of the hair planted in the direction opposite to the protrusion direction of the arc-shaped part of a net member. FIG. It is a figure which shows the directivity of the hair of Example 9. FIG. It is a figure which shows the directivity of the hair of Example 10. FIG. It is a figure which shows the state which planted so that hair might be irregular and directivity may not be one direction.

  Hereinafter, a preferred embodiment of a wig base according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a plan view of a wig using an embodiment of a wig base according to the present invention. The illustrated wig base 1 is constituted by a net member 2 having a shape conforming to the shape of the top of the wearer's head, and the wig is formed by implanting hair 15 in the net member 2. As shown in FIGS. 3A and 3B, the net member 2 has a substantially fan-like shape in which the structure of the mesh 3 has an arcuate portion 5 in part. And it arrange | positions so that the protrusion direction of the circular arc of the circular arc shaped part 5 of the mesh | network 3 may face the forehead part side (F direction of FIG. 1) of the wig base 1. As shown in FIG. The net member 2 is originally stretched over the entire surface of the wig base 1 and the hair 15 is planted at a predetermined location. However, only a part of the net member 2 is shown in FIG.

  The net member 2 is formed by knitting a filament 20 of 55 to 223 dtex in a substantially plane, and a space closed in a plane by weaving the filaments 20 is called a “mesh”, and FIG. FIG. Then, as shown in FIG. 3 (a) as the first embodiment of the net member 2, the filament 20 is continuously formed in an arc shape with a predetermined center angle, so that the arc-shaped portion 5 is knitted. In addition, the connecting portion 6 is knitted by connecting the mesh 3 at the apex vicinity 11 of each filament 20 and the left and right end portions 12 of the arc-shaped portion 5, and the a row and the b row of the arc-shaped portion 5 are staggered. It is continuously organized to become. In addition, the shape stabilizing yarn 7 is stretched substantially in parallel so as to straddle the opening of the mesh 3 from the arc-shaped portion 5. The mesh 3 knitted in this way has a fan-like shape. Here, the center angle is an angle formed when the left and right end portions 12 of the arcuate portion 5 are connected to the connecting portion 6 where the linear portions extending from the left and right end portions 12 intersect each other. Further, in the net member 2 shown in FIG. 3B as the second embodiment, the arcuate portions 5 having a predetermined center angle are continuously connected as in the first embodiment. It differs from the wig base 1 of 1st Embodiment by the point knitted continuously so that c row and d row of the arc-shaped part 5 may become the same row. Note that the same is true in that the mesh 3 is configured by the shape stabilizing yarn 7 straddling the opening of the mesh 3 in a direction substantially orthogonal to the arcuate portion 5 so as to extend across the opening.

  Next, the installation of the hair 15 on the net member 2 will be described. As shown in FIG. 4A, the hair 15 is implanted only in the arcuate portion 5. In the vicinity of the forehead and top of the wig base 1, the hairs 15 are regularly planted at predetermined intervals so that the knots 10 of the hairs 15 do not overlap along the protruding direction of the arcuate part 5. It is preferable to plant so that the hair ends are substantially perpendicular to the tangential direction of the arcuate portion 5 and have directivity in the protruding direction. By planting in this way, the directivity of the hair 15 becomes radial and intersects with the hair 15 implanted in the adjacent mesh 3, so that the rising of each hair 15 is improved. For example, as shown in FIG. 7, when the hair 15 is not regularly planted and is planted so as not to have directivity perpendicular to the arcuate portion 5, the directivity of the hair 15 is irregularly dispersed. Therefore, the appearance of the hair 15 becomes unnatural due to the lack of unity of the hair 15, which is not preferable, and the directivity of the hair 15 does not radiate in the vicinity of the forehead and the top of the head, and the hair 15 starts from the base of the hair 15. This is not preferable because the hairs 15 are overlapped and converged, and the respective hairs 15 fall down due to their own weights, and a good rise of the hairs 15 may not be obtained. Further, as shown in FIG. 4B, in the vicinity of the back of the wig base 1, the hair 15 is regularly arranged so as to be substantially perpendicular to the tangential direction of the arcuate portion 5 and to have directivity on the opposite side to the protruding direction. It is preferable to plant. As shown in FIG. 7, when the hair 15 is planted irregularly and so that the directivity is not unidirectional, the hair 15 is dispersed without being focused. Further, the hair 15 at the outer peripheral edge 16 of the wig and the wearer's own hair are not compatible with each other, and a natural appearance and hairstyle cannot be obtained particularly near the nape of the wig wearer.

  In addition, it is not preferable to implant the hair 15 in the connecting portion 6 or the shape stabilizing yarn 7 which is a portion other than the arc-shaped portion 5. If the connecting part 6 is implanted, the filament 20 constituting the connecting part 6 may be loosened, and since the connecting part 6 is not arcuate, the hair 15 to be implanted can have a predetermined directivity. This is because the hair 15 may converge and a good rise may not be obtained. Further, when the shape stabilizing yarn 7 is implanted, the filament may be loosened, and since the shape stabilizing yarn 7 is stretched linearly in a direction perpendicular to the arcuate portion 5, the hair to be implanted This is because the directivity of 15 does not become radial and the hair 15 is difficult to stand up, which is not preferable.

  Here, the center angle 9 of the arc of the arc-shaped portion 5 is preferably in the range of 85 ° to 155 °. As shown in FIG. 5, even when the center angle 9 of the arcuate part 5 is less than 85 °, the hair 15 is implanted in the radial direction, so that it intersects with the hair 15 implanted in the adjacent mesh 3. Although the effect that the rising of the hair 15 is improved is recognized, since the radial direction of the hair 15 is restricted because the length of the arc-shaped portion 5 is relatively short, the hair 15 is implanted in the adjacent mesh 3 accordingly. Crossing with the hair 15 is reduced. In addition, as shown in FIG. 6, when the center angle exceeds 155 °, the effect of improving the rising of the hair 15 is recognized, but the shape of the arc-shaped portion 5 is a semicircle (center angle 180 degrees). ) To approach the state, the directivity of the implanted hair 15 becomes too wide. Therefore, in order to obtain a more sufficient effect, it is preferable that the center angle 9 of the arc of the arc-shaped portion 5 is in the range of 85 ° to 155 °. Further, in the case of the net member 2 in which the center angle of the arcuate portion 5 exceeds 155 °, the hair 15 can be more effectively raised by setting the planting range of the hair 15 to a range of 85 ° to 155 °. Can be realized. Moreover, the net | network member 2 which changed the magnitude | size of the opening part of a mesh according to the residual hair state of a wig wearer's head can be used. In addition, the arrow in a figure represents the directing direction of the hair 15. FIG.

  When the net member 2 configured as described above is used for the wig base 1, if the arc-shaped portion 5 is disposed so that the protruding direction of the arc-shaped portion 5 is other than the forehead portion side F of the wig, Since the directivity of the hair 15 toward the forehead portion does not become radial in the forehead portion, which is the most important for obtaining a natural appearance, or in the vicinity of the top of the head, the rising of the hair 15 becomes insufficient and natural. This is not preferable because the volume and hairstyle cannot be obtained.

  The material of the net member 2 is not particularly limited, but polyester excellent in shape stability is preferable. In order to improve the wearing feeling and fitting feeling of the wig, both the vertical and horizontal directions of the net member 2 are in accordance with the JIS L1096 stiffness test method. Based on the method A (45 degree cantilever method), it is preferable that the bending resistance in the vertical direction and the horizontal direction is in the range of 15 mm to 70 mm. This is because when the net softness of the net member 2 is less than 15 mm, the net member 2 becomes slightly soft, so that the wig base 1 tends to be deformed and the fit may be slightly lowered. On the other hand, when the bending resistance of the net member 2 exceeds 70 mm, the net member 2 becomes slightly hard, and thus the entire wig base 1 may be easily moved with respect to a large movement of the head.

  Further, it is preferable that a plurality of the shape stabilizing yarns 7 are arranged so as to go from the arc-shaped portion 5 to the fan-shaped straight portion. Although it is possible to arrange an odd number of shape stabilizing yarns 7, it is more preferable to arrange an even number symmetrically with respect to the center line 8 of the arcuate portion 5 if possible. This is because if the number of the shape stabilizing yarns 7 is an odd number and there is a deviation in the arrangement of the mesh 3 in the opening, the balance in maintaining the shape of the arcuate portion 5 is deteriorated, and the wearing comfort may be reduced. Needless to say, the provision of the arc-shaped portion 5 can improve the rising of the hair 15 regardless of the bending resistance of the net member 2 and the number of the shape stabilizing yarns 7.

[Manufacture of wigs]
Next, the manufacturing method of the wig using the wig base which concerns on this invention is demonstrated.

  First, as a first step, the net member 2 is fixed to a male gypsum mold imitating the shape of the head of a wig wearer so that the protruding direction of the arc-shaped part 5 faces the forehead part side. After that, a thermosetting urethane resin solution is applied, dried at a heating temperature of 100 ° C. for 8 hours and molded, and then the net member 2 is removed from the gypsum mold. Here, the thermosetting urethane resin solution used was 6.5 g of E-64A (No. 1.2.3) manufactured by Nissin Resin Co., Ltd., 3.5 g of E-65BS (No. 1), A mixture of a predetermined amount of methyl ethyl ketone is used. In addition, the bending resistance of the net member 2 can be adjusted by adjusting the blending amount of methyl ethyl ketone.

  Next, as a second step, the belt-like net member 4 is attached to the outer periphery of the net member 2 formed in the shape of the head of the wig wearer. The band-shaped net member 4 is attached by first cutting the band-shaped net member 4 to a length of 70 cm or more with a width of 14 mm, and then applying and molding a resin solution as in the first step. Next, after the unnecessary net at the outer peripheral end of the net member 2 is cut off, the belt-like net portion 4 is attached to the outer periphery of the net member 2 in a half-folded manner, and is integrated with the net member 2 by sewing to wig base 1. Make it.

  Next, as a third step, hair 15 is implanted in the wig base 1. In order to plant the hair 15, first, the wig base 1 is fitted and fixed to the male head-shaped mold. Next, in the vicinity of the forehead portion and the top of the head, the net member 2 has a protruding direction of the arc-shaped portion 5 and is perpendicular to the tangential direction of the arc-shaped portion 5 and the hair tip of the hair 15 faces the protruding direction of the arc. After the stylus is inserted from the surface of the knives and the filament constituting the net member 2 is scooped up, the hair 15 is hooked and tied to the heel of the heel needle. On the other hand, in the vicinity of the back of the head, the hair 15 is implanted so that the tip of the hair faces in the direction perpendicular to the tangential direction of the arcuate portion 5 and opposite to the protruding direction of the arc.

  The hair 15 to be planted may be either natural hair or artificial hair, and is planted by connecting a folded portion obtained by folding the central portion of the hair 15 to the arc-shaped portion 5 of the net member 2. At that time, in order to make the directivity of the hair 15 constant, planting is performed on the arcuate portion 5 at a predetermined interval so that the knots do not overlap each other.

(Residual strain rate measurement method)

[Comparative Example 2]
A wig was manufactured by implanting hair in the same manner as in Example 1 except that the arc-shaped portion 5 was arranged so that the protruding direction of the arc-shaped portion 5 was directed toward the right side of the wig.

〔result〕
In all the wigs of Example 1-8, the directivity of the hair 15 on the forehead portion side of the wig base 1 becomes radial, and the hair 15 implanted in the wig base 1 rises sufficiently, so that the natural volume and hair The style was obtained. In addition, the directivity of the hair 15 on the occipital side is directed in one direction to prevent the hair 15 from rising, the hair 15 of the wig and the wearer's own hair become familiar at the outer peripheral edge of the wig base 1, and the area around the nape is particularly familiar. A natural look and hairstyle were obtained. In addition, as shown in FIG. 3A, in Example 1, since the a-line and b-line of the arcuate part are knitted alternately, the hair 15 implanted on the forehead part side overlaps. Since the number of intersections, for example, the intersection points 1a and 2a, increases and each hair 15 supports each other and easily rises, a natural volume feeling can be obtained even with a small amount of hair. In addition, since the net member 2 can improve the tensile strength while maintaining an appropriate softness, a satisfactory wig fit and wig shape stability can be obtained, and the wig can be comfortably worn. It was. Further, as shown in FIG. 3B, in Example 2, the gaps 17 between the meshes were larger than in Example 1, and the number of arc-shaped portions where hair can be implanted was reduced. There were many intersections where the hairs overlapped with each other in a radial pattern, and a natural volume feeling was obtained.

  The wig of Example 9 was recognized to have an effect that the rising of the hair 15 was improved. However, as shown in FIG. 5, by setting the center angle of the mesh 3 to 80 °, the natural volume feeling and the desired hair Example 3 was more preferred in terms of style set.

  The wig of Example 10 was recognized to have an effect of improving the rising of the hair 15, but as shown in FIG. Example 4 was more preferred.

  The wig of Example 11 was recognized to have an effect of improving the rising of the hair 15, but the wig base 1 was slightly soft because the bending resistance of the net member 2 was 10 mm in the vertical direction and 16 mm in the horizontal direction. At the time of planting 15, the mesh 3 was stretched. In terms of fit, Examples 5 and 6 were more preferable.

  The wig of Example 12 was recognized to have an effect of improving the rising of the hair 15, but because the bending resistance of the net member 2 was 61 mm in the vertical direction and 75 mm in the horizontal direction, the wig base 1 was a little stiff and the head There was a tendency that the entire wig base 1 was easy to move with respect to the large movement. In terms of fit, Examples 5 and 6 were more preferable.

  Since the number of the shape stabilizing yarns 7 is arranged in the wig of Example 13, the residual strain rate of the net member 2 is as low as 2% in the vertical direction and 1% in the horizontal direction, and the shape stability of the wig base 1 is obtained. It was. However, since many shape stabilizing yarns 7 are arranged in the mesh 3, there is a tendency that the area of the gap between the mesh 3 is reduced and the air permeability is slightly lowered. Therefore, Examples 7 and 8 were more preferable in terms of wearing comfort.

  In the wig of Example 14, the shape stabilizing yarn 7 is not arranged symmetrically with respect to the center line of the arc-shaped portion 5, so that there is a deviation in the arrangement of the mesh 3 in the opening, and the arc-shaped portion There was a tendency that the balance in maintaining the shape of 5 was slightly lowered. Therefore, Examples 7 and 8 were more preferable in terms of fit.

  On the other hand, the wig of Comparative Example 1 is arranged so that the protruding direction of the arc-shaped portion 5 faces the occipital region of the wig, so that the directivity of the hair 15 toward the forehead portion does not become radial, and the natural wig is natural. The hair 15 in the vicinity of the forehead, which is the most important for obtaining a good appearance, was not sufficiently raised, and the natural volume and hair style of the hair 15 could not be obtained. Further, the hair 15 rises on the occipital side where the hair 15 rises less naturally, resulting in an unnatural appearance.

  The wig of the comparative example 2 is arranged so that the protruding direction of the arc-shaped part 5 is directed to the right side of the wig. Thus, like the comparative example 1, the wig is the most important for obtaining a natural appearance as a wig. The hair 15 in the vicinity of the forehead did not rise sufficiently, and the natural volume and hair style of the hair 15 could not be obtained. Further, the hair 15 rises on the side of the temporal region where the hair 15 rises less naturally, resulting in an unnatural appearance. Furthermore, since the arrangement of the shape stabilizing yarn is also directed to the temporal side, a satisfactory tensile strength in the front-rear direction cannot be obtained.

  Since the wig of Comparative Example 3 was not provided with the shape stabilizing yarn 7, the residual strain rate of the net member 2 was 18% in the vertical direction and 6% in the horizontal direction. Since the residual strain rate in the longitudinal direction exceeds 15%, the strain of the net member 2 that occurs during daily wig attachment / detachment increases, and the wig base 1 is deformed by long-term use of the wig, resulting in a reduced fit. The shape stability of the wig base 1 was not obtained.

  The wig of Comparative Example 4 has the residual strain rate of 16% in the vertical direction and 5% in the horizontal direction by arranging the shape stabilizing yarn 7 in parallel in the horizontal direction, and the residual strain rate in the vertical direction is 15%. %, The strain on the net member 2 gradually increases due to the tensile load from the forehead to the back of the head that occurs during daily wig attachment / detachment, and the wig base 1 is deformed to reduce the fit. The shape stability of 1 was not obtained.

  The wig of the comparative example 5 produced the wig using the rectangular net member which is not illustrated, and the directivity of the planted hair which is not illustrated converges in the same direction, and the force from above is several times. When it was added, the hair did not stand up due to its own weight, etc., and a natural volume feeling could not be obtained. Further, when the number of hairs to be planted in the mesh is increased in order to obtain a sense of volume, the amount of hair as a wig increases more than necessary, resulting in an unnatural appearance.
