Description

  The present invention relates to a wig, and more particularly to a wig that is less prone to cracking.

  Conventionally, wigs are manufactured by implanting hair such as natural hair or artificial hair on a wig base such as a net or artificial skin. Human hair usually grows almost vertically from the hair follicle through the scalp, but the tip side of the hair has a horizontal flow, that is, directivity, depending on the curved shape of the head. For example, the flow (directivity) of the hair on the front side of the head depends on the curved state of the head, such as toward the forehead, backward on the occipital side, and laterally on the temporal side. Flowing in the direction. Therefore, in order to produce a natural wig, it is preferable to plant hair with directivity. As a method of planting with such directivity, a method of unidirectional planting is employed. Specifically, as shown in FIG. 14, the hair H has a predetermined directivity with a predetermined interval between only the weft X or the warp Y (the weft X in FIG. 14) constituting the net base 100. It is a method to give and tie. In addition, as for the arrow H, the intersection K with the weft X shows the planting point of hair, and the direction of the arrow shows the direction of directivity.

  When the hair is planted on the net base 100, in a general conventional binding method, the hair is bound so as to have directivity in a direction perpendicular to the yarn constituting the net base. . Since the planting is usually performed manually and tied to the wig base by pulling the hair in a certain horizontal direction, it has directivity in the pulled certain direction. According to such a method, since the planted hairs are arranged regularly with directivity in the same direction, it is possible to easily set a hairstyle that is easy to bundle and fix with a predetermined hairstyle. Therefore, there is an advantage that the hairstyle is not easily disturbed.

  Further, as described above, the hair flow direction, that is, the direction of directivity differs in each region such as the forehead, the top of the head, and the back of the head. Therefore, in order to manufacture a natural wig, it is necessary to plant with directivity corresponding to each region when artificial hair is planted on the wig base. Therefore, as shown in FIG. 15, the wig base 101 is divided at the boundaries 102 a to 102 e, and hairs are implanted with different directivities as indicated by arrows in the defined areas A to D. .

  However, the wigs produced by such a method may cause unintended hair splits (hereinafter referred to as “hair cracking”) as they are used, and reveal the wig base near the root of the implanted hair. As a result, there is a problem that the wearing of the wig is known to others. Hair cracking occurs when the hair implanted in the wig cannot move freely and cannot flexibly follow the external force such as the movement of the hair by the wind or combing with a comb. Hereinafter, a description will be given with reference to the drawings.

  FIG. 16A is a cross-sectional view of the vicinity of human scalp, that is, the scalp where the own hair grows. The own hair 110 is fixed by a hair follicle 112 inside the skin 111. The skin 111 on which the own hair 110 grows has elasticity, and there is a recess 113 between the hair 110 and the hair 110 near the surface. The elastic movable range 114 in which the skin 111 can elastically follow the left and right movement of the own hair 110 is secured. For this reason, the own hair 110 is securely fixed by the own hair fixing layer 115 including the hair follicle 112, while the elastic movable range 114 allows it to move elastically and against external force. You can follow it without difficulty.

  On the other hand, FIG. 16B is a cross-sectional view of artificial skin in which hair is implanted. The hair 120 is planted through the artificial skin 121 and is provided with a hair stop layer 124 so that the knot 123 does not come out after being fixed with the knot 123. As described above, the hair 120 is securely fixed by the hair fixing layer 125 including the artificial skin 121 and the hair stopper layer 124, and the elastic movable range of the hair is not provided on the surface of the artificial skin 121. It is difficult to elastically follow external forces. For this reason, once the hair is bent in the vicinity of the root, the hair itself will bend and become difficult to correct.

  FIG. 16C is a cross-sectional view of a net in which hair is implanted. The hair 130 is bound to the net line 131 of the net. As described above, the hair 130 is directly attached to the net and is securely fixed. However, since there is no elastic movable range, it is difficult to elastically follow various movements. For this reason, once the hair is bent in the vicinity of the root, the hair itself will bend and become difficult to correct. Moreover, since there is no hair fixing layer like artificial skin, when the knot 42C is loosened over time, the hair may fall asleep without rising.

  For hair cracking, (1) hair cracking due to the planted hair not standing up, (2) hair cracking occurring near the border of each region due to different directivity of the hair depending on the region, (3) in a bundle shape There are three types of cracks that occur between the broken hairs.

First, (1) hair cracking due to the planted hair not rising will be described.
As described above, in the conventional wig manufacturing method, hair is regularly planted at a predetermined interval by being tied to one of warp or weft in the net mesh. Since planting is usually done manually and tied by pulling the hair in a certain direction, the planted hair has a directivity in a certain direction perpendicular to the tied yarn. According to such a planting method, since the planted hairs are regularly arranged in the same direction, if the force from above is applied several times, the hair may fall asleep without standing up.

  Since hair cracking is a state in which the roots of the hair fall asleep in opposite directions, if the hair rises and has a volume, it is difficult for the hair to break. Moreover, even if a crack occurs in the root part of the hair, it is possible to prevent the crack from being exposed by styling the hair tip. However, if the planted hair falls asleep without standing up, the hair is easily separated from the root, and the wig base is exposed. In addition, when the hair is sleeping, once the hair breaks, even if it is corrected by styling, the cracks often occur again after a lapse of time.

The above-mentioned (2) will be described with respect to the cracks that occur in the vicinity of the border of each region due to the different directivity of the hair depending on the region.
As described above, the human head has different hair flowing directions in each region such as the forehead, the top of the head, and the back of the head, and in order to reproduce a natural flow without a sense of incongruity with a wig, FIG. As shown in FIG. 2, it is necessary to plant hair with directivity adapted to each region. However, in the region A, the hair is planted so that the hair tip flows toward the frontal region, and in the region B, the hair tip flows so as to flow toward the back head, the hair direction is true on both sides of the boundary 102c. On the other hand, in the region C, the hair tips are planted so as to flow toward the left head periphery, and in the region D, the hair tips flow toward the right head periphery. At the border 102a, the border 102e between the regions A and D, the border 102b between the regions B and C, and the border 102d between the regions B and D, the hairs are orthogonal to each other, which causes hair cracking.

The cracking that occurs between the bundled hairs of (3) will be described.
If many hairs with the same directivity are implanted at almost the same point on the wig base, these properties are close to each other and may become bundles. As described above, since the root of the planted hair is fixed to a base such as a net, the movement of the hair is limited and cannot be flexibly adapted to various movements. For this reason, if the planted hair clumps into a bundle and the hair is wrinkled, even if the hair style is adjusted by combing the hair, the hair will be bundled into several bundles over time, and the bundle Hair cracks are likely to occur between the shaped hairs.

  Here, as disclosed in FIG. 8 of Patent Document 1, a method of implanting a plurality of hairs in the warp and weft of the net member is conceivable. According to the wig in which the hair is planted in this manner, the amount of hair is increased compared to the conventional wig 100, and the planted hair rises. Therefore, the root of the hair due to the planted hair of (1) not standing up. It is possible to prevent the cracks generated in the vicinity.

Further, FIG. As shown in Fig. 3, a set of two hairs planted with a directivity of 90 degrees from each other, a predetermined interval is set according to the directivity set for each region of the hair on an artificial skin member or the like. A method of opening and planting can be considered. According to such a planting method, since the hair is planted with a certain degree of variation and is not easily bundled, the above-mentioned (3) prevents the cracking that occurs between the bundled hairs. Can do.
JP-A-9-273016 International Publication No. 2006/020176 Pamphlet

  However, in the method disclosed in FIG. 8 of Patent Document 1, since the planted hair is planted perpendicular to the wig base and has no horizontal directivity, the natural hair flow is reproduced. I can't. Moreover, since the hair with the same directivity is planted in the net network without a gap, the hair overlaps from the root to the tip of the hair, and the hair does not come apart and becomes a bundle. That is, the above-mentioned (3) “breaking of hair between bundled hairs” cannot be prevented.

  Further, FIG. In the method disclosed in No. 3, it is not possible to prevent the above-mentioned (1), the cracking of hair that occurs near the root of the hair due to the planted hair not standing up. Also, the two hairs planted with a directivity of 90 degrees from each other have a strong directivity in the direction of the bisector of the corners they form, so a constant directivity for each region as shown in FIG. In the case of planting with a hair, it is not possible to prevent the above-mentioned (2), “hair cracking that occurs near the border of each region due to different directivity of hair depending on the region”.

  This invention is made | formed in view of the said problem, and it aims at providing the wig which a hair crack does not produce easily.

  In order to achieve the above object, the wig of the present invention is a wig in which a plurality of hairs are planted on a wig base, and each planting pattern includes four hairs planted with different directivities. Are regularly arranged at a predetermined interval.

  When the points where the hairs included in the planting pattern are connected are connected, a zigzag shape is formed. In addition, the planting pattern is a set of 8 hairs with the same directivity every 2 strains, and the line connecting the points where the 2 adjacent hairs are planted is the other 6 hairs. It is desirable to have a shift parallel to the zigzag line connecting the implanted positions.

  When the wig base is made of a net member, it is desirable that the number of hairs planted with different directivities on the sides forming one mesh of the net member is two or less.

  The surface of the wig base is partitioned into a plurality of regions, and the plurality of regions have different orientations of the planting pattern. It is desirable to draw a zigzag line at the boundary between the plurality of regions.

  The direction of the planting pattern is different for each region on the wig base. At this time, it is desirable that the boundary of the region on the wig base draws a zigzag line, and the inner angle of each vertex of the zigzag line is about 40 °.

  According to the wig of the present invention, since the four hairs in the planting pattern are planted with different directivities, the hairs of the same planting pattern or other planting patterns are at least one another. By crossing at several points, it becomes a state that supports the vicinity of the roots, making it easy to stand up without having to increase the amount of hair specially, and to move elastically at the part below the point where the hair crossed Therefore, the problem of hair cracking can be solved. Therefore, the vicinity of the root of the planted hair is not exposed, and the wig base portion is not easily exposed. Further, since the hair is planted with different directivities on the entire wig base, a variety of style sets are possible, unlike conventional wigs. In addition, by including four strains of hair with different directivities in one planting pattern, the directivity of the hair on both sides of the border is completely achieved even if the orientation of the planting pattern is reversed on both sides of the border. It is not reversed and hair cracks are less likely to occur.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1A is a plan view showing a part of the wig of the first embodiment. The wig 1 has hair H implanted in a net member 2 as a wig base. If necessary, the surface of the net member may be covered with artificial skin, or the hair 3 may be directly planted on the artificial skin. As shown in FIG. 1 (A), the weft yarn constituting the net member 2 is X, the warp yarn is Y, and the upper side of the mesh in the first row among the meshes defined by these is A, B, C from the left end. .., And the left side of the first row is a, b, c,. Further, the upper side of each mesh in the second row is Aa, Ba, Ca... From the left end, and similarly, the left side of the second column is aA, bA, cA. The same definition is applied from the third row and the third column.

  Each hair H1-8 is natural hair or artificial hair, and is planted by connecting a folded portion obtained by folding a central portion of one or a plurality of hairs into a weft X or a warp Y of the net member 2. . At that time, the hair has a direction so as to be substantially perpendicular to the net member 2 and in a plane perpendicular to the tied thread, but in addition to this, due to the force applied at the time of implantation, Directivity in the horizontal direction with respect to the net member 2 is provided. Such horizontal directivity is represented by an arrow in the drawing. Moreover, the planted hair makes 1 share per hair knot tied to the net member 2. The hair constituting this strain may be composed of one or more hairs, for example, about 2 to 4 hairs.

  In this embodiment, using such directivity, 8 plants planted in a predetermined area are set as one planting pattern, and planted repeatedly according to this planting pattern. Specifically, as shown in FIG. 1A, the first hair H1 is planted with directivity in the “front” (upper side of the drawing) direction as indicated by an arrow at the position of Ca on the weft X. The second hair H2 is planted at the position of bB on the warp Y with a directivity in the “left” direction as indicated by an arrow. The third hair H3 is planted with a directivity in the “rear” (lower side of the paper) direction as indicated by the arrow at the position Bb on the weft X, and the fourth hair H4 is the warp Y It is planted with directivity in the “right” direction indicated by the arrow at the position of the upper cB. Up to this point, hair having four-directional directivity has been implanted. Further, the fifth hair H5 has directivity in the “front” direction as indicated by the arrow at the position of Cc on the weft X, and the sixth hair H6 has an arrow at the position of dB on the warp Y. As shown, the seventh hair H7 has directivity in the “left” direction, and the seventh hair H7 has directivity in the “rear” direction as indicated by an arrow at the position of Ad on the weft X. H8 is planted with directivity in the “right” direction as indicated by the arrow at the position of eA on the warp Y, and the first to fourth strains described above by planting the fifth to eighth strains Similarly, hair having directivity in four directions is implanted. By planting in this way, when the points where the hair is planted are connected, a zigzag shape is formed.

  FIG. 2 is a plan view schematically showing a state in which hair is implanted in the net member 2 in accordance with the implantation pattern of the present embodiment. Actually, the hair has a strong directivity perpendicular to the wig base, but also has a horizontal directivity as described above, which is indicated by an arrow. The vertical and horizontal dimensions of the net member 2 are 1 mm, and the hair is implanted at a predetermined position as described above. In the present embodiment, the intersections 10a to 10j are generated by implanting the hair in a state where the front and rear, right and left directivities are provided with a predetermined interval. Thereby, as shown in FIG. 3, it will be in the state where the several hair H mutually supports near a root. For this reason, the hair rises and the elastic movable range 20 is secured near the root, so that the hair can cope with various movements, so that the hair does not easily break.

  By the way, the seventh hair H7 and the eighth hair H8 shown in FIG. 1A are implanted at the position of Ad on the weft X and the position of eA on the warp Y. That is, as shown in FIG. 1 (C), the line Z2 connecting the planting points of the seventh hair H7 and the eighth hair H8 is the position where the first to sixth hairs are implanted. There is a shift in a parallel direction with respect to the zigzag line Z1 connecting the two. This is because each planting pattern is provided at regular intervals in the transverse direction (weft X direction). As shown in FIG. 1 (B), the seventh hair H7 and the eighth hair H8 are wefted. When planted at the position of Bd on X and at the position of eB on the warp Y, warp yarns in which no hair is planted are generated between the planting pattern P2 and the adjacent planting pattern P3, that is, the gap 30 is formed. As a result, this portion of the net member 2 is exposed. On the other hand, if the planting pattern P2 and the planting pattern P3 are too close to each other, the amount of hair becomes too large and bundles are generated. In the present embodiment, since the seventh hair H7 and the eighth hair H8 are planted by shifting to the left from the row of the first to sixth hairs H1 to H6 as described above, It is possible to prevent hair bundles from occurring without generating 30.

  In addition, as shown in FIG. 4, when planted with a spacing in the row direction of the planting pattern, the hair planted on the side forming one mesh of the net 2 becomes one strain, and FIG. Compared with the planting pattern shown in Fig. 2, the spacing between the hairs to be planted is widened, the number of strains planted for each region is reduced, and the net 2 is exposed, which is not preferable. Therefore, in this embodiment, as shown to FIG. 1 (A), the hair planted in the edge | side which forms one mesh | network of a net member is made into two stocks, and it does not leave the planting space | interval of a row direction on warp Y Planted in 5 rows from a to e. As a modification, as shown in FIG. 1D, the same result can be obtained even if the directivity of each strain is reversed left and right.

When planting is performed according to the above rules, there are a total of 24 combinations of directivity of the first to fourth hairs, which can be selected from among them, but the above two examples are particularly desirable. The reason will be described below.
FIG. 5 shows six planting patterns in which the directivity of the first strain is “front”, and FIG. 6 shows six planting patterns in which the first strain is “rear”. 6 types of planting patterns with stocks of “left” and “right” are shown. In order to prevent hair cracking, as shown in FIGS. 2 and 3, it is necessary to superimpose the vicinity of the hair roots and to support each other, so it is preferable that there are many intersections near the hair roots.

  In the six combinations shown in FIG. 5, “front” → “left” → “back” → “right” in (1) and “front” → “right” → “back” → “left” in (2). In the planting pattern of “20”, 20 intersections within 5 mm from the root are confirmed, whereas “front” → “left” → “right” → “back” in (6) and “front” in (5) ”→” Right ”→“ Left ”→“ Back ”, there are 8 locations,“ Front ”→“ Back ”→“ Left ”→“ Right ”in (3) and“ Front ”in (4) → In the “back” → “right” → “left” planting pattern, there are 10 locations. Therefore, there are the most intersections of hair near the root, (1) “front” → “left” → “back” → “right” and (2) “front” → “right” → “back” → “left” The planting pattern "is most preferable.

  In addition, (1) “back” → “right” → “front” → “left” and (2) “back” → “left” → “front” → “right” planting patterns shown in FIG. 7, (1) “Left” → “Rear” → “Right” → “Front” and (2) “Left” → “Front” → “Right” → “Rear” planting pattern, Similarly, (1) "Right"-> "Front"-> "Left"-> "Rear" and (2) "Right"-> "Rear"-> "Left"-> "Front" shown in Fig. 8 Intersections of 20 hairs were confirmed.

  In this way, there are 8 out of 24 planting patterns in which 20 hair intersections can be confirmed. However, in order to increase the number of hair near the forehead and the rim of the wig, which is most easily noticeable by a third party, and the wig is easily exposed, the first strain starts planting in the “front” direction. It is preferable. Hereinafter, this point will be described in detail.

For example, as shown in FIG. 9 (1), when a net having a 1 mm square mesh is used, if the first stock is planted with directivity in the “front” direction, 1 cm ² (10 eyes × 10 eyes) ) 18 plants can be planted in the area. The hair to be planted is folded in half, and the vicinity of the center binds to the filament to form a V-shape, so two hairs are planted at one location. When planted, 36 hairs will be implanted. The “Left” direction of the second strain is 15 strains / cm ² (30 hairs), the “Back” direction of the third strain, and the “Right” direction of the fourth strain is 17 strains / cm ² (34 hairs). It can be seen that the number of hairs in the “front” direction can be maximized by planting the stock from the “front” direction.

Next, as shown in (2) in FIG. 9, when the first strain starts to be planted from the “rear” direction, 30 plants are planted in 1 cm ² in the “front” direction. As shown in 3) and (4), when the first stock is started from the “left” and “right” directions, 30 plants will be planted in 1 cm ² , so the first stock is “front”. Compared to starting from the direction, there is a big difference. For the above reasons, among 24 planting patterns, “front” → “left” → “back” → “right” in FIG. 5 (1) and “front” → “right” in FIG. 5 (2). The planting pattern of “right” → “back” → “left” is most preferable.

  When manufacturing the wig of this embodiment, hair is planted repeatedly according to the planting pattern mentioned above. Originally, the number of planting patterns corresponding to the area of the wig is provided from the forehead portion to the back of the head, but for convenience, eight planting patterns U1 to U8 will be described as shown in FIG.

  First, planting in the order of planting patterns U1 to U4 from the forehead portion to the occipital region, and then in the order of planting patterns U5 to U8 from the forehead portion to the occipital region in adjacent positions in the temporal region. Plant. In FIG. 10, only the right-side head direction is shown. Repeat the planting in adjacent positions with the same planting pattern to plant the entire wig.

  As described above, when hairs having the same directivity are planted adjacent to each other, the adjacent hairs overlap from the roots to the ends of the hairs, so that the hairs having the same directivity are bundled in a bundle. Instead, cracks occur between other bundles of hair. Specifically, when the distance between the hairs having the same directivity is only one glance away from the net member 2, the hair tends to clump together, and the hair is broken between the other bundles of hair. Since it will occur, it is not preferable. On the other hand, when the hair interval is wider than necessary, specifically, when the net member 2 is separated by more than the third mesh, the vicinity of the hair roots does not support each other, and the hair This is not preferable because the hair will be raised without standing up.

  The strains planted at the boundaries between the planting patterns in the left-right direction, for example, the spacing in the left-right direction between the first plant H11 of the planting pattern U1 and the first plant H51 of the planting pattern U5 is two net members 2. The eyes are separated. As a result, the hair is not clumped in a bundle shape, and it is possible to prevent the hair from cracking by spreading the portion from the vicinity of the middle to the hair tip. On the other hand, the stock planted at the boundary between the planting patterns in the front-rear direction, for example, the space in the front-rear direction between the eighth plant H18 of the planting pattern U1 and the first plant H21 of the planting pattern U2 is spaced. Since there is no decrease in the number of strains to be planted, it is possible to prevent the net 2 from being exposed, and since the interval between the net members 2 is one glance, the vicinity of the roots of the hair supports each other. Thus, it is possible to prevent hair cracking.

  One or more hairs may be planted on the side forming one mesh of the net member 2, or three or more hairs having the same directivity on the side forming one net of the net member. It is also possible to plant. Furthermore, it is also within the scope of the present invention to plant two strains of hair having different directivities on one side forming the mesh of the net member.

  In order to prevent the wig from being exposed near the periphery, it is necessary to plant a large number of forehead and surrounding hairs. However, when planting from the hair having directivity of "front" in the planting pattern of the first embodiment from the forehead portion toward the back of the head, the portion on the weft X having a small number of planting shown in FIG. That is, Aa, Ab, Ac, and the like may correspond to the outermost edge portions 40a to 40d of the peripheral edge portion shown in FIG. 11, and the wig is easily exposed. Therefore, as shown in FIG. 11, peripheral edges 41a to 41d having an appropriate width are provided around the wig from a hair having “front” directivity, and the planting direction is switched between these borders. Lines 42a to 42d are defined, and planted from the outermost edge portions 40a to 40d of the respective peripheral portions toward the central region 43 of the wig. In addition, in this embodiment, in order to ensure the width | variety which can plant eight stocks, ie, one planting pattern, in order to prevent exposure, the peripheral part 50 of about 2 cm is provided around the wig. The central region 43, which is a portion other than the peripheral portions 41a to 41d, is implanted from the forehead toward the occipital region using the above-described implantation pattern. In FIGS. 11 and 12, the white arrow indicates the direction of the above-described planting pattern, that is, the direction of directivity of the hair to be planted first.

  When manufacturing a wig by the method of such 1st embodiment, there exists a possibility that a hair crack may arise on the switching lines 42a-42d of the planting direction. In order to prevent this, the method of the second embodiment was considered. That is, as shown in FIG. 12, by making the borders 51a of the regions B, C, and D that are in contact with the region A into zigzag lines, the implanted hairs are staggered in each region, and FIG. As shown, the camouflage effect is produced and hair cracking can be reduced as compared with the boundaries between the regions divided by the straight lines.

  When planted on a so-called regular net having a square mesh, the directivity of the hair is limited to four directions from the number of sides of the net mesh, and the directivity of the hair is opposite or orthogonal on both sides of the boundary of the region. Therefore, it is easy to break the hair. Therefore, it is necessary to provide a zigzag boundary at an appropriate position. In general, in the vicinity of the sledging on both sides of the forehead part, a person has different hair flows in the front direction and the side direction. In general, the flow of hair is directed differently in the direction of the top of the head and the direction of the back of the head at a position 2/3 in the longitudinal length of the head from the forehead. Therefore, a zigzag line 51a is formed from the forehead part to the line 54 of the longitudinal length 2/3 of the head, starting from the turn-around 52a and 52b and starting from the vicinity of the outer peripheral edge 53 of the wig. Region A is formed. Further, zigzag boundaries 51b and 51c are formed along the perpendicular line extending from the intersections 55a and 55b of the zigzag boundary 51a to the line 54 of the longitudinal length 2/3 of the head from the forehead portion to the outer peripheral line 53. The regions B, C, and D are defined by these boundaries.

  A preferable shape of the zigzag boundaries 51a to 51c will be described. As shown in FIG. 13 (A), the left and right amplitudes w1 and w2 from the center line 61 of the zigzag line 60 are set to 0.75 cm, and the width w3 between every other vertex is set to 1 cm. The angle of the apex θ of the triangle defined by 60 is preferably about 40 degrees. For example, as shown in FIG. 13C, when the angle of the apex θ of the zigzag is more acute than 40 degrees, for example, about 30 degrees, the area of the triangle defined by the zigzag line 60 becomes narrower. Depending on the amount of hair, the hair cannot be sufficiently planted in the triangular area, and the effect of preventing inappropriate hair separation is reduced. On the other hand, as shown in FIG. 13D, when the angle is large, for example, about 75 degrees, the boundary between the regions divided by the straight line as shown in FIG. Become.

  As described above, it is preferable that the angle of the apex θ of the triangle defined by the zigzag line 60 is an angle that can correspond to various hair amounts and nets, but the triangle size is more than necessary. Should not be too big. For example, as shown in FIG. 13B, when the width w4 from the apex to the base is 2.5 cm and the base length w5 is 2 cm, the angle is about 45 degrees, but the triangles constituting the zigzag This is not preferable because the area becomes large and there is a possibility that it cannot be applied to a wig with a small area for planting hair.

  As described above, the wig of the present invention prevents hair cracking, and can be implemented in various forms without departing from the gist thereof. For example, if the net mesh has an octagonal shape, the hair can be implanted with directivity in eight directions. It is necessary to set various elements in a well-balanced manner, such as the amount of hair to be planted and the curl direction of the hair.

It is a top view which shows a part of wig which concerns on 1st embodiment of this invention. FIG. 2 is a plan view schematically showing the state of FIG. 1. It is a front view which shows the state of the hair in FIG. It is a top view which shows another embodiment.
