Description

  The present invention relates to a wig, and more particularly to a wig in which a large number of hairs are connected to one net of a net.

  Wigs are manufactured by tying hair into a net of a base that covers the wearer's head. The number of hairs tied to one mesh of the net is 1 to several, and the hair is tied at an optimum number depending on the purpose of wearing the wig. There are various ways to tie this, and each has its own weaknesses and strengths. Important requirements for tying are that it is easy to tie, difficult to tie, not damaging the net when tying, and that no significant curling occurs due to large tension on the hair when tying (for example, patents) Reference 1).

JP2015-209624

  The method of tying disclosed in Patent Document 1 is a technique suitable for tying one to several hairs in one net of a net. However, when tying a large number of hairs, for example 10 hairs or more, it is not always an appropriate method. This is because if a large number of hairs are tied to one net of the net, the knot becomes weak and easy to unravel.

Moreover, when a large number of hairs are tied to one net of the net, a volume feeling is easily obtained, but on the other hand, it may be felt unnatural and a wig feeling may occur.
Because of such a problem, the number of hairs connected to one mesh of the net is about 8 at most.

  The present invention provides a wig that reduces the production time and production cost of the wig and solves the above-mentioned problems by connecting more than 10 hairs to one net of the net. It is.

The wig according to the present invention is
A wig with multiple hairs tied to one net of the base net,
The number of hairs tied to one mesh of the net is
10 or more and 30 or less in the vicinity of the top of the head including the toothpick,
Other than the top of the head, the number is 35 or more and 70 or less.

  The hair is mainly composed of artificial hair having shape memory properties.

  A base is further provided on the head contact side of the net in which a plurality of hairs are tied to the one mesh.

Until now, it has been difficult to tie a large number of hairs to one net of a net.
The first reason is that it has been considered that an unnaturalness is conspicuous and a wig feeling appears because an excessive volume feeling is obtained.
The second reason is that it has been considered that if a large number of books are tied together and tied to one net, they cannot be tied tightly and can be solved immediately.

  However, it was found that the place where the unnaturalness is conspicuous due to the excessive volume feeling is mainly in the vicinity of the top of the head including the toothpick, and the other places do not give an unnatural feeling even if there is a volume feeling. Also, it was found that the natural appearance can be maintained near the top of the head as long as the number of nets connected to one net of the net is a certain number.

We have also developed a new technique that makes it difficult to unravel from the mesh by mainly using artificial hair with shape memory as the hair. In addition, even if tied tightly, a large number of pieces come into contact with the net in a thick state, so even if a large tension is generated during tying, the tension is distributed over a wide contact area and damage to the net is unlikely to occur. Accordingly, it is possible to tie stronger than usual, and in combination with performing the shape memory processing, it is possible to bind in a state that is practically difficult to unravel. In other words, we were able to break the existing concept of being easy to solve.
These new findings have made it possible to provide wigs with many excellent features. The features of this wig are listed below.

  First, it was possible to connect a large number of hairs, which could not be considered before, to one net, and succeeded in significantly reducing the production time and cost of the wig.

  Secondly, by reducing the number of nets connected to one mesh in the vicinity of the top of the head, it is possible to maintain a natural appearance while producing a volume feeling.

  Thirdly, a wig that is easy to curl and difficult to curl could be obtained.

  Fourth, since a large number of hairs are tied together, even if they are tied tightly, the tension applied to one hair is small, so even long-haired wigs are less likely to curl and have high quality. It became possible to obtain hair quality.

  Fifth, if a large number of hairs are tied together, the knot will increase, and the knot may hit the head when worn, but on the head contact side of the net where multiple hairs are tied to one mesh, Furthermore, by providing a base, it was possible to completely eliminate such discomfort when wearing.

It is the schematic diagram which looked at the base part of the wig which concerns on this invention from the front.

Embodiment.
<Composition of wig>
The structure of the wig according to the present invention will be described below with reference to FIG. The following description discloses a good example related to the present invention, and the present invention is not limited to the embodiment.

  The wig according to the present embodiment is a wig in which a plurality of hairs are tied to one mesh of the net 1 as a base, and the number of hairs to be tied to one mesh of the net is the vicinity of the top including the toothpick The number 2 is 10 or more and 30 or less, and the number 3 other than the parietal portion 3 is 35 or more and 70 or less.

  Moreover, it is desirable that the hair is mainly composed of artificial hair having shape memory properties.

  Furthermore, a feeling of wearing can be improved by further providing a base material 4 on the head contact side of the net 1 in which a plurality of hairs are tied to one net.

  In the present invention, the top of the head means the vicinity of the top of the head (the top of the head) including the toothpick, and means the part from the vicinity of the top of the head to the front hair.

  In the present invention, the artificial hair having shape memory property means artificial hair that is cooled after being heated to 60 ° C. or more and that maintains its shape stably. For example, artificial hair having a shape memory property that is stable enough to maintain the shape even when wet in the rain. Artificial hair, which is called heat-resistant shape memory hair and finished into one hair by combining several thin fibers, is a typical artificial hair having shape memory properties.

<Production of wig>
Next, the main points of the wig manufacturing method will be described.
First, a predetermined number of hairs are bundled and passed through the mesh of the net 1 using a dedicated tool, and returned to the original direction from the adjacent mesh, and tied tightly. Tie with a little stronger force than when connecting one to several. Since a large number of hairs are bundled into a thick state, even if a large tension is generated during tying, the tension is distributed over a wide contact area and the net is not damaged.

  The same operation was performed on the whole net, and finally the whole was heated at 60 ° C. to 80 ° C. for about 1 minute and then naturally cooled. By this shape memory treatment, the hair knots are stored in a knotted shape, and are not easily unwound from the mesh of the net 1.

Next, a verification experiment was performed to determine the optimum number of hairs to be connected to one mesh of the net 1.
The hair is heat-resistant shape memory hair, and the thickness of one of the hairs is about 70 μm to 80 μm, which is almost the average Japanese thickness. In the verification experiment 1, a wig using human hair was also produced for comparison.

<Verification experiment 1>
A plurality of wigs having different numbers of hairs connected to one net of the net 1 were prepared. The number of the wigs was changed from 5 to 90 every 5 pieces to produce 18 wigs. In addition, the hair used two kinds of heat-resistant shape memory hair and human hair, and the shape memory treatment described above was performed on both.

  With the net 1 fixed, a bundle of hair tied to one mesh of the net 1 was pulled vertically from the net 1 with a force of about 500 g, and the bundle of hair was pulled out or the knot was damaged. The case was considered bad. Then, it was divided by the total number of hair bundles, and this was taken as the defective rate.

  As shown in Table 1, the defect rate increased as the number of bundles increased. In human hair, the defect rate increased rapidly with 65 or more hairs, exceeding 1%. On the other hand, in heat-resistant shape memory hair, the defect rate as low as 70 could be maintained.

It was found that by applying shape memory treatment to heat-resistant shape memory hair, knots are difficult to break and sufficiently strong binding is possible up to 70 bundles.
In addition, it was confirmed by another experiment that the artificial hair having the shape memory property is not limited to the heat-resistant shape memory hair, but exhibits almost the same tendency. Furthermore, when artificial hair having shape memory property and human hair are mixed in a bundle, if the mixing ratio of artificial hair having shape memory property is 50% or more, similar results can be obtained. Also confirmed.

<Verification experiment 2>
Next, a verification experiment was conducted on how the natural appearance changes when the number of bundles is changed.
In the verification, wigs with different numbers of bundles are installed in order, and 25 men and women (age 20s to 40s) evaluate the feeling of wearing the wigs. The ratio of responding that the wig wearing feeling was natural was used as the evaluation value.

Table 2 shows the results. With respect to the top of the head, the evaluation was high when the number was 30 or less, and the evaluation began to drop greatly when the number was 35 or more. On the other hand, with respect to other parts, the evaluation was high at 70 or less, and the evaluation began to drop greatly at 75 or more.
<Verification experiment 3>

The wig produced by the production method described above was curled in an oven or the like. When the number of bundles was changed, a verification experiment was conducted as to whether the sense of bundle of curls was maintained well over a certain period.
As a verification method, 50 females (age 20s to 40s) were worn for 1 month, and evaluation was made as to whether or not the curl feeling was well maintained after wearing. The ratio of responding that it was maintained well was taken as the evaluation value.

Table 3 shows the results. The evaluation was high with 20 or more, and the evaluation began to drop significantly with 15 or less.
<Verification experiment 4>

  Finally, after the wig was manufactured, the rate of crimping was verified. An evaluation value was obtained by dividing the number of defective bundles by the total number of bundles.

  As shown in Table 4, with 30 or more, the occurrence rate of shrinkage was as low as 0.7% or less. Further, even with 10 or more, the occurrence rate of shrinkage was a relatively low value of 1.3% or less.

<Judgment from verification experiment>
From the results of the above verification experiment, the optimum number of bundles was determined by the following procedure.
From the verification experiment 1, the number of bundles is preferably 70 or less.
From the verification experiment 2, the number of bundles is preferably 30 or less at the top of the head and 70 or less for the other parts.
From Verification Experiment 3, the number of bundles is preferably 20 or more.
From the verification experiment 4, the number of bundles is preferably 30 or more.

  From the above, it can be determined that the number of sites other than the parietal region is preferably 30 or more and 70 or less. On the other hand, with regard to the top of the head, it was determined that 30 or less were desirable in consideration of the natural appearance. And in order to keep the minimum favorable about a shrinkage, it was set to 10 or more.

<Summary of the present invention>
The present invention is a challenge to a preconceived concept that has been considered difficult to connect a large number of hairs to one mesh of a net, and began with an analysis of why it has been considered difficult.

The first reason is that it has been considered that an unnaturalness is conspicuous and a wig feeling appears because an excessive volume feeling is obtained.
The second reason is that it has been considered that if a large number of books are tied together and tied to one net, they cannot be tied tightly and can be solved immediately.

  However, it was found that the place where the unnaturalness is conspicuous due to the excessive volume feeling is mainly in the vicinity of the top of the head including the toothpick, and the other places do not give an unnatural feeling even if there is a volume feeling. Also, it was found that the natural appearance can be maintained near the top of the head as long as the number of nets connected to one net of the net is a certain number.

We have also developed a new technique that makes it difficult to unravel from the mesh by mainly using artificial hair with shape memory as the hair. In addition, even if tied tightly, a large number of pieces come into contact with the net in a thick state, so even if a large tension is generated during tying, the tension is distributed over a wide contact area and damage to the net is unlikely to occur. Accordingly, it is possible to tie stronger than usual, and in combination with performing the shape memory processing, it is possible to bind in a state that is practically difficult to unravel. In other words, we were able to break the existing concept of being easy to solve.
These new findings have made it possible to provide wigs with many excellent features. The features of this wig are listed below.

  First, it was possible to connect a large number of hairs, which could not be considered before, to one net, and succeeded in significantly reducing the production time and cost of the wig.

  Secondly, by reducing the number of nets connected to one mesh in the vicinity of the top of the head, it is possible to maintain a natural appearance while producing a volume feeling.

  Thirdly, a wig that is easy to curl and difficult to curl could be obtained.

  Fourth, since a large number of hairs are tied together, even if they are tied tightly, the tension applied to one hair is small, so even long-haired wigs are less likely to curl and have high quality. It became possible to obtain hair quality.

  Fifth, if a large number of hairs are tied together, the knot will increase, and the knot may hit the head when worn, but on the head contact side of the net where multiple hairs are tied to one mesh, Furthermore, by providing a base, it was possible to completely eliminate such discomfort when wearing.
