Description

  According to the present invention, by combining a stretchable net and a non-stretchable net to the wig base according to the part of the head, the shape of the wig can be well retained, and the wearability and fit to the head can be improved. The present invention relates to an all-head wig that can be produced and a method for producing the same.

Generally, when hair is lost due to hair loss, etc., there is a method of concealing the part where the hair was lost by wearing a wig, but when the hair loss is extensive, the partial wig cannot cover it. The use of a full-head wig that covers the entire part has been performed.
The wig for all heads covers the entire head, but the wearing comfort, so-called fit, is emphasized rather than the partial wigs, but the wig base used for the conventional wigs for all heads has drawbacks in the structure and material etc. Many were unable to get a satisfactory fit.

With regard to the structure of the wig base, there are generally few problems with the fit because the curve of the head shape of the wearer is generally gentle on the front side of the head, but the inclination is strong on the back side of the head. It was difficult to fit the person's head shape.
Therefore, a technique has been proposed in which a stretchable net is used for the wig base and the fit is improved by matching the net with the shape of the head (Patent Document 1).
Moreover, the fit feeling is improved by joining the wig base for the whole head into three nets divided from the left head to the left occipital region, from the right to the right occipital region, and the occipital region located between them. A technique has been proposed (Patent Document 2).
Furthermore, cover the back of the head with a stretchable net and cover the area other than the back of the head with the net. A wig base for all heads joined by a net is known (Patent Document 3).

JP-A-6-220708 JP-A-5-302209 Japanese Utility Model Publication No. 61-137622

  However, in the technique of Patent Document 1, although the net has elasticity and can be fitted to the head shape, one piece is used for the left and right heads on the rear side of the head and the back head between these heads. Therefore, when the neck is moved back and forth, left and right, a strong tension is generated in the left and right heads and the back of the head, and this tension cannot be released and wrinkles and distortion occur in the net. These wrinkles and distortions are not preferable because the hairstyle becomes unnatural and the wig base can be seen from the outside.

Moreover, although patent document 2 has divided | segmented the net | network for every site | part, since the inclination from the right-and-left side head part to the back of the head part is strong, even if it divides | segments a net | network which does not have elasticity into 3 sheets, a favorable fit is obtained. It is difficult.
As a countermeasure against this, it is conceivable to use a known stretchable net. As shown in FIGS. 33 and 34, the stretchability is divided into a left head piece 1a, a right head piece 1b, and a back head piece 1c. The sewing lines 2 a and 2 b of the net 1 are V-shaped from the vicinity of the center 3 a of the neck 3 to the crown 4.

  That is, in the vicinity of the center 3a of the neckline 3, the joint width between the left and right head pieces 1a, 1b and the back head piece 1c is narrow, the sewing lines 2a, 2b are too close, and the left and right head pieces 1a, 1b and the back head A sufficient area cannot be obtained for each of the pieces 1c. Therefore, even if the stretchable net 1 is used, such a wig-based structure is not satisfactory because it cannot obtain sufficient stretch in the left and right only gripping directions (the left and right side head pieces 1a and 1b directions). You can't get a good fit.

Furthermore, in the former technique proposed in Patent Document 3, that is, a wig base for all heads that covers the back of the head with a stretchable net and covers the area other than the back of the head with the net, the net covering the area other than the back of the head is not It is not disclosed whether to use an elastic net or an elastic net.
If the net is stretchable, the area covered by the stretchable net covers a wide area, so that distortion and wrinkles are likely to occur, and a desired hairstyle cannot be made. In addition, when the net covering other than the occipital segment is non-stretchable, the shape of the head can be retained, but the stretchability cannot be exerted in the region of the left and right head segments, and a sufficient fit is achieved. It will be something that cannot be obtained.

On the other hand, the latter technique proposed in Patent Document 3, that is, a wig base for all heads in which the front side of the head is joined with two nets and the left and right side heads and the back of the head between them are joined with three nets. However, it is not disclosed whether to use a non-stretchable net or a stretchable net for these nets.
Even if a non-stretchable net is used on the front side of the head and a stretchable net is used on the left and right side heads and the back of the head, there is distortion when the wig is worn for the reason described with reference to FIGS. Since it becomes easy to generate | occur | produce and cannot follow the motion of a head, it becomes a thing which cannot obtain a satisfactory fit.

  The present invention has been made in the background of such circumstances, and its purpose is to improve the fit and fit to the head by limiting the joint of the stretchable net to a specific position. It is to provide a wig for all heads that can be manufactured and a method for manufacturing the wig.

  In order to achieve the above object, the wig for all heads of the present invention is a wig for all heads comprising a wig base formed into a head shape and hair implanted in the wig base, The wig base is formed by joining a non-stretchable net that covers the front side of the head and a stretchable net that covers the back side of the head, and the joint between the stretchable net and the non-stretchable net The elastic net is positioned between the ear-to-ear line extending from the top of the ear piece to the top of the head and the line extending from the chin tip to the golden point through the upper part of the left and right ear pieces. The left and right head pieces and the back head piece located between the left and right head pieces are divided into three pieces. It is characterized by being provided in a direction perpendicular to the line connecting the sights.

The human head shape begins to tilt toward the back of the head from the ear-to-ear line, and continues from the upper end of the pinna to the vicinity of the occipital ridge in the horizontal direction of the occipital region, but the inclination is near the golden point. Become the hardest. For this reason, when the vicinity of this golden point is stretched with a non-stretchable net, it does not match the inclined shape on the rear side of the head and lacks a fit.
In addition, when the joint between the non-stretchable net and the stretchable net is positioned in front of the head from the ear-to-ear wire, the area of the non-stretchable net decreases and the area of the stretchable net Although it increases, it is difficult to maintain the shape because the stretchable net is more stretchable than the non-stretchable net when compared with the non-stretchable net.

In particular, after the hair has been implanted, the mesh of the stretchable net tends to stretch, wrinkles and distortions occur, and problems such as inability to fit the head shape of the wig wearer are not appropriate.
Therefore, in order to cover the vicinity of the golden point with a stretchable net and fit the inclined shape on the back side of the head, the joint between the non-stretchable net and the stretchable net is connected to the ear-to-ear line and the golden point. It is preferable to set it inside the passing line.

Next, the elastic net on the rear side of the head is divided into three pieces, a left head piece and a right head piece, and a back head piece sandwiched between them. The right and left heads are provided in the direction perpendicular to the line connecting the left and right collars located on the neckline, that is, in the front-rear direction of the head. Necessary and sufficient area for expansion and contraction is secured on the side of the neck and the back of the head.
Thereby, sufficient area which can be expanded-contracted to the neckline part side of a right-and-left side head piece and a back head piece is ensured, and high elasticity can be exhibited.

For the non-stretchable net on the front side of the head, a net made of a single fiber material made of synthetic resin, for example, and having a thread diameter of 80 μm to 200 μm and a mesh of 10 mesh to 80 mesh may be used.
When the thread diameter of the non-stretchable net is 80 μm or less, there is a concern about the strength of the mesh because the thread diameter is thin, the mesh breaks at the time of planting, and the hair cannot be firmly bound to the mesh. There is a possibility that the knot of the hair turns over to the wig wearing side (scalp side), the direction of the hair is not determined, and the desired hair style cannot be made.
On the other hand, when the thread diameter of the non-stretchable net is 200 μm or more, it becomes difficult to make the knots of the implanted hair, and the knots of the hair loosen during the use of the wig. You may not be able to make your hairstyle.

Furthermore, when the mesh of the non-stretchable net is 10 mesh or less, it is difficult to obtain a desired hair thickening feeling when the hair is implanted, and there is a possibility that wearing of the wig is visually recognized from the outside. On the other hand, if the mesh of the non-stretchable net is 80 mesh or more, the amount of hair to be planted on the non-stretchable net increases, and the weight of the wig increases unnecessarily. If the number of hairs to be adjusted is adjusted to be small, there will be an increase in the number of meshes in which the hair is not implanted, and the wearing of the wig may be visually recognized from the outside.
Accordingly, for the non-stretchable net, as described above, a single fiber material made of a synthetic resin having a thread diameter of 80 μm to 200 μm and a mesh of 10 mesh to 80 mesh is preferable.

  The stretchable net on the back side of the head may be formed of a left and right side head piece and a back head piece made of, for example, a single fiber material and / or a composite fiber material made of synthetic resin having flexibility and elasticity. Specifically, for example, a polyester elastic yarn that obtains stretchability by fusing two types of polymers having different physical properties at the spinning stage and causing the polymers having different elongation rates to contract is preferable. Further, polyurethane fiber may be used for the core portion and polyester fiber may be used for the sheath portion.

  Furthermore, as the conditions of the stretchable net, those having a thread diameter of 180 μm to 400 μm and preferably about 30 mesh to 60 mesh are preferable, and the elongation ratio in the longitudinal and lateral directions is in the range of 30% to 100%, respectively. A ratio in which the horizontal direction is about “1.2” to “3” is more preferable when the expansion ratios in the direction and the vertical direction are different and the vertical direction is “1”.

  For example, when the diameter of a stretchable net is 180 μm or less, when hair such as human hair or artificial hair is implanted, the knotted ball of the implanted hair is thin on the side of the wig wearing side (scalp side) ), The direction of the hair is not fixed, and the desired hairstyle may not be made. Conversely, if the diameter of the elastic net is 400 μm or more, the weight of the wig increases and the air permeability decreases. In addition, the wearing feeling of the wig is also not suitable.

  In addition, when the stretchable net is 30 mesh or less, a desired hair thickening feeling cannot be obtained when the hair is implanted, and it may be visually recognized that a wig is attached from the outside. Conversely, if the stretchable net is 60 mesh or more, the amount of hair to be planted on the stretchable net increases, making it difficult to make a desired hairstyle. When the amount is adjusted to be small, the meshes where hair is not implanted increase, and the meshes may be visually recognized from the outside.

In addition, when the stretch rate in the longitudinal direction and the lateral direction of the stretchable net is 30% or less, the desired stretch amount cannot be obtained, so that the fit is lacking.
On the other hand, if the stretch rate of the stretchable net is 100% or more, the stretchable net will stretch too much when wearing a wig, so it will not fit the wearer's head shape, and the stretchable net will stretch too much There is a risk that the knot of the hair will be exposed.
Furthermore, when the stretch rate is “1”: “1” and the stretchable net stretches evenly in the vertical and horizontal directions, when the stretchable net is stretched by wearing a wig, the direction of the crown and the direction of the neckline , The same phenomenon as 30 mesh or less occurs by extending evenly in the four directions of the left head direction and the right head direction, and the mesh in which the hair is implanted is extended and the wig base is visually recognized from the outside. This is not preferable.

  Further, when the stretch rate of the stretchable net is stretched at a ratio “5”: “1” with “5” in the horizontal direction and “1” in the vertical direction, there is a difference between the stretch rate in the horizontal direction and the vertical direction. Because it is too large, even if one mesh fits the head shape when the wig is worn, the stretch rate of the other mesh is low, so it does not expand and contract, making it difficult to obtain the desired fit

.
Therefore, as described above, the left and right side head pieces and the back head piece formed of the elastic net have a thread diameter of 180 μm to 400 μm, about 30 mesh to 60 mesh, and stretch ratios of 30% to 100% in the vertical and horizontal directions, respectively. % Is more preferable, and when the elongation ratio in the horizontal direction and the vertical direction is “1” in the vertical direction, a ratio in the horizontal direction of “1.2” to “3” is more preferable.

  Furthermore, the present invention provides the aforementioned occipital segment with high elasticity in a direction perpendicular to the line connecting the left and right projections, and at the same time, tying the left and right projections to the left and right head segments, respectively. You may have high elasticity in the direction parallel to the line, or conversely, the occipital segment has high elasticity in the direction parallel to the line connecting the left and right collars, and at the same time the left temporal segment It is preferable that the right and left head pieces have high elasticity in a direction orthogonal to a line connecting the left and right projections.

If all the three highly stretchable directions of the left and right side head pieces and the occipital piece are made to coincide with the direction perpendicular to the line connecting the left and right collars, the direction perpendicular to the line connecting the collars, That is, an appropriate stretchability can be obtained in the front-rear direction of the head on the rear side of the head, but sufficient in the direction parallel to the line connecting the left and right projections, that is, in the left-right direction of the head on the rear side of the head Elasticity cannot be obtained.
Similarly, when all the three highly elastic directions of the left and right head pieces and the back head piece are made to coincide with the direction parallel to the line connecting the left and right projections, Although suitable stretchability is obtained, sufficient stretchability cannot be obtained in the direction orthogonal to the line connecting the left and right projections, that is, in the front-rear direction on the back side of the head.

  Therefore, as described above, the occipital segment has high elasticity in the direction orthogonal to the line connecting the left and right projections, and at the same time, the lines connecting the left and right projections to the left and right head segments respectively. You may give high elasticity in the parallel direction, or conversely, give the occipital piece high elasticity in the direction parallel to the line connecting the left and right projections, and at the same time the left and right head pieces A good fit is obtained by giving each of the head pieces a high stretchability in a direction perpendicular to a line connecting the left and right projections.

Further, according to the present invention, the joining of the left side head piece, the right side head piece, and the back head piece can be sewn or bonded. When the left head piece, the right head piece, and the back head piece are joined together, it is beneficial to use both side stitching and staggered stitching.
The stretchable net may be coated with a synthetic resin solution on the entire surface. A turn-up preventing member or a sewing thread may be provided on the front head side edge of the non-stretchable net and / or the neckline side edge of the stretchable net. An adjuster for adjusting the size of the wig may be attached to at least one of the left and right head pieces.
Further, according to the present invention, a shape maintaining member can be attached to the wig base and the neckline.

  The method for producing a wig for all heads of the present invention comprises a wig base molded into a head shape, and hair implanted in the wig base, and the wig base is located near the top of the head from the front side of the head. A non-stretchable net that covers the head and a stretchable net that covers the back of the head, and the stretchable net includes a left head piece, a right head piece, and left and right head pieces. A method of manufacturing an all-head wig configured by joining three pieces with a occipital segment located therebetween, a first step of entering a predetermined production line in a male-shaped gypsum mold having a head shape; A second step of forming the first base for the front side of the head by forming the non-stretchable net into a predetermined shape of the head; and after forming the elastic net into the shape of the head, The elastic net and the elastic net for the occipital segment are sewn or bonded to form a second A third step of manufacturing a sage, a fourth step of manufacturing a wig base by sewing or bonding the first base and the second base, and implanting hair into the wig base. It is characterized by having a fifth step and a sixth step for performing a hair-stopping process at a predetermined position on the wig mounting side of the wig base after the planting.

  According to the wig of the present invention, the head shape of the wig can be maintained by using a non-stretchable net in the front side of the head and the vicinity of the top of the head, and the back and left and right side heads are By joining the three stretchable nets of the temporal head piece and the occipital piece and setting the joining position of these three stretchable nets in a direction perpendicular to the line connecting the left and right collars, Since the area on the neckline side of the sex net is secured widely, the left and right head pieces and the back head piece respond smoothly to the movement of the neck while improving the fit to the head, and the wrinkles and distortion of the net Effectively prevents and keeps the natural hairstyle well.

  Furthermore, the high expansion / contraction direction of the occipital segment is set to a direction parallel to or perpendicular to the line connecting the left and right projections, and the high expansion / contraction direction of the left and right occipital segments located on both sides of the occipital segment is set. By setting the occipital segment in the direction that intersects with the high expansion and contraction of the occipital segment, align the front side of the head with the vicinity of the top of the head when wearing the wig, and then pull the left and right scooping up part, so that The wig can be easily attached by being stretched.

Further, by joining the left head piece, the right head piece, and the occipital piece by sewing or bonding, the joined state of these three pieces can be kept strong. In particular, the joining of the left head piece, the right head piece and the back head piece is sewn, and this sewing is used in combination with side-by-side stitching and staggered stitching, so that the joining state is kept strong and stretchable. Can also be secured.
The width of the joint between the left head piece and the back head piece, or the joint part between the right head piece and the back head piece, should be about 5 mm in consideration of stretchability and the strength or aesthetics of the sewn part. Is desirable. When these joint widths are set to 5 mm, it is necessary to prevent the line of parallel stitches and the line of staggered stitches from overlapping. The zigzag stitch width is preferably about 3 mm. Note that the positions of the side stitching and the staggered stitching can be changed as appropriate according to the width of the joint portion.

Comparing the combination of the above-mentioned side stitching and zigzag stitching with the case of sewing with two side stitches, the stretch rate of the joint is only about 24.4% with two side stitches, In the combined use of line stitching and zigzag stitching, the elongation percentage of the joint becomes 35.6%, and it can be seen that high stretchability can be secured by zigzag stitching.
The elongation rate was measured by partially changing the 6.14.1 elongation rate (2) B method (constant load method) in JIS L 1096, cutting the test piece to 0.5 cm × 15 cm, Except for adding an initial load of 1.13 g, the test was performed according to JIS standards.

Therefore, it is conceivable to sew only by zigzag stitching without using parallel stitching. Certainly, this stitching can ensure high stretchability, but with zigzag stitching alone, there is a problem in the bonding strength, and the thread is It is not appropriate because the sewn part is detached due to fraying or the like.
Further, when two stitches are sewn together without using zigzag stitching, the stretch rate is not sufficient, and high stretchability cannot be secured, which is not appropriate.
In addition, as a joining means of a joining part, although the adhesion | attachment using an adhesive agent can also be performed, considering that it is more preferable to ensure a stretching property and intensity | strength, joining by sewing is suitable.

Furthermore, the present invention can maintain the shape and elasticity of the elastic net when using a wig for all heads by applying a synthetic resin solution to the elastic net used on the back side of the head. It is possible to prevent distortion and wrinkles of the net.
The synthetic resin solution is preferably a water-soluble polyurethane resin solution composed of about 50% water-soluble polyurethane resin and about 50% water. For example, in the case of a solvent-based polyurethane resin solution, it is used in the solution. There is a possibility that the elasticity of the synthetic resin of the elastic net material deteriorates due to the organic solvent, and is lost due to curing.

  In addition, since the water-soluble polyurethane solution penetrates into the gaps between the two types of polymers having different elongation rates even in the stretchable net, the shape retention can be maintained. Can be prevented, and a desired hairstyle can be easily made.

  Furthermore, the present invention provides a curl-up preventing member on the forehead side edge of the non-stretchable net and / or the neckline side edge of the stretchable net, thereby effectively rolling up the wig for all heads. Can be prevented.

Furthermore, by providing sewing threads on the front head side edge of the non-stretchable net and / or the neckline side edge of the stretchable net, these portions can be easily reinforced and a satisfactory fit can be obtained. It is possible to prevent the wig wearing from being exposed due to the front edge of the front head and the side edge of the neckline.
In addition, the stretchable net can be adapted to the user's head by its expansion and contraction, but the stretchable net cannot be accommodated by providing an adjuster on at least one of the left and right head pieces. Further size adjustments are possible.

Hereinafter, the best mode of the wig for all heads based on this invention is demonstrated based on drawing.
FIGS. 1 to 9 show an embodiment of the present invention. FIG. 1 is a side view of a wig for all heads, FIG. 2 is a rear view of the wig for all heads, and FIG. FIG. 4, FIG. 5, FIG. 6 and FIG. 7 are rear views of full-head wigs for explaining the stretching direction of the stretchable net, and FIG. FIG. 9 is an enlarged view showing details of the periphery of the adjuster.
The wig 10 for all heads shown in FIGS. 1-3 is equipped with the wig base 11 attached to the whole user's head, and the hair hr implanted in this wig base 11, and the front side of the head From the hairline 12a to the upper part of the left and right auricles E1 (the right side is not shown), the entire head from the hairline 12a to the collar leg 12b in the occipital region is covered.

  The wig base 11 is formed by joining a non-stretchable net 14 covering the front side of the head and a stretchable net 15 covering the back side of the head, and connecting the stretchable net 15 and the non-stretchable net 14. 10 to 12, the head portion P1 where the ear-to-ear line EL connecting the upper portions E1a of the left and right pinna E1 and the midline L1 intersect, and the chin C1 Is located in a range A sandwiched between a so-called golden point GP where a line L2 connecting the upper part E1a of the left and right auricles E1 intersects the median line L1.

The elastic net 15 on the back side of the head includes a left side head piece 15a and a right side head piece 15b, a back head piece 15c positioned between the left and right side head pieces 15a, 15b, and a lower side of the back head piece 15c. It is divided into four pieces with a continuous collar foot piece 15d.
Each of the joint 17a between the left head piece 15a and the back head piece 15c, and the joint part 17b between the right head piece 15b and the back head piece 15c, is a hollow part on the left and right sides of the neck at the most intense part near the back of the head, so-called honey It is provided in a strip shape in a direction orthogonal to the line L3 connecting the collars M1 and M2, and the joint 17c between the back head piece 15c and the neckline piece 15d is striped on the line L3 connecting the collars M1 and M2. Is provided.

  As a result, a wide area sufficient for expansion and contraction is secured on the neckline side of the left and right head pieces 15a and 15b and the back head piece 15c. This makes it possible to disperse the tension acting on the stretchable net 15 due to the movement of the neck, sufficiently preventing wrinkles and distortion of the stretchable net 15 and obtaining a satisfactory fit.

Human hair, artificial hair, or the like is used for the hair hr shown in FIG. 3, and is bound using a knotting method such as a hull or a knot between the non-stretchable net 14 and the stretchable net 15 constituting the wig base 11. Is done.
For the non-stretchable net 14 on the front side of the head, a net made of a single fiber material made of synthetic resin, for example, and having a thread diameter of 80 μm to 200 μm and a mesh of 10 mesh to 80 mesh may be used.

Further, the elastic net 15 on the rear side of the head includes four pieces of left and right side head pieces 15a, 15b, a back head piece 15c, and a collar foot piece 15d, for example, a single fiber material made of synthetic resin having flexibility and elasticity. And / or a composite fiber material. Specifically, for example, a polyester elastic yarn that obtains stretchability by fusing two types of polymers having different physical properties at the spinning stage and causing the polymers having different elongation rates to contract is preferable. Further, polyurethane fiber may be used for the core portion and polyester fiber may be used for the sheath portion.
Moreover, it is good to apply | coat the polyurethane resin solution for preventing the wig 10 for all heads to slip | deviate during mounting | wearing to the collar foot piece 15d.

  Furthermore, as the conditions of the stretchable net 15, those having a thread diameter of 180 μm to 400 μm and preferably about 30 mesh to 60 mesh are preferable, and the elongation ratio in the longitudinal and lateral directions is in the range of 30% to 100%, respectively. A ratio in which the horizontal direction is about “1.2” to “3” is more preferable when the expansion ratios in the horizontal direction and the vertical direction are different and the vertical direction is “1”.

The above-described stretchable nets 15 having different stretch rates in the horizontal and vertical directions are arranged with the mesh directions of the left and right head pieces 15a and 15b and the back head piece 15c as shown in FIGS. 4 to 7, the white thick arrow indicates the high extension direction, and the thin line arrow indicates the low extension direction.
4 and 5, the mesh on the high extension rate side of the occipital segment 15c is arranged in a direction perpendicular to the line L3 connecting the left and right collars M1 and M2, and further, the left segment 15a and the right segment The mesh on the high elongation rate side of 15b includes 80 ° to 140 ° including the direction parallel to the line L3 connecting the left and right grips M1, M2 perpendicular to the mesh direction of the high elongation rate of the occipital segment 15c. The occipital segment 15c and the left and right head segments 15a and 15b on both sides thereof intersect with each other in the high expansion and contraction direction.

  That is, in the case shown in FIGS. 4 and 5, the occipital segment 15c is given high elasticity in the front-rear direction perpendicular to the line L3 connecting the observatory M1 and M2, and the left occipital segment 15a and the right occipital segment The part 15b has a direction that intersects with high elasticity acting in the longitudinal direction of the head of the occipital piece 15c, that is, has high elasticity in the left and right direction of the head. The wig 10 is suitable for a wearer having a general head shape or a wearer that protrudes greatly from the parietal bone to the occipital bone and obtains a good fit.

Further, in the above-described stretchable net 15 having different stretch rates in the horizontal and vertical directions, the mesh directions of the left and right head pieces 15a and 15b and the back head piece 15c can be arranged as shown in FIGS.
6 and 7, the mesh on the high extension rate side of the occipital segment 15c is arranged in parallel with the line L3 connecting the left and right collars M1 and M2, and the left and right head segments 15a and 15b The mesh on the high elongation rate side is 80 ° to 140 ° in the direction perpendicular to the mesh direction of the high elongation rate of the occipital segment 15c, that is, in the direction perpendicular to the line L3 connecting the left and right collars M1 and M2. The occipital segment 15c and the left and right head segments 15a and 15b on both sides thereof intersect with each other in the high expansion and contraction direction.

  That is, in the case shown in FIGS. 6 and 7, the occipital segment 15c is given high elasticity in the lateral direction of the head, and the left and right temporal segments 15a and 15b are The all-head wig 10 with high stretchability has such characteristics and is suitable for wearers with a general head shape or wearers that protrude greatly from the parietal bone to the temporal bone. Suitable for obtaining a good fit.

As shown in FIGS. 1 to 7, the non-stretchable net 14 is provided with a turn-up preventing member 20 with a predetermined width on the front head side edge covering the hairline 12 a on the front side of the head. The net 15 is also provided with a turn-up preventing member 21 on a collar foot piece 15d covering the neck foot 12b.
These turn-up preventing members 20 and 21 are obtained by applying a synthetic resin solution as artificial skin to the mounting surface (scalp side surface) of the non-stretchable net 14 and the collar foot piece 15d, and when the wig 10 for the whole head is mounted. In addition, the turn-up preventing members 20 and 21 are in contact with the scalp and hair at the hairline 12a and the neckline 12b of the wearer and in the vicinity thereof, thereby preventing the turn-up of the wig 10 for all heads and also serving as a non-slip.
