Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a partial wig, and more particularly to a method for manufacturing a partial wig capable of preventing the wig from curling up in the forehead of a user. .

[Conventional technology and problems]

Conventionally, as a wig base of a partial wig, an artificial skin made of a soft synthetic resin having an appropriate thickness, or a net formed by woven or knitted fabrics with nylon fibers arranged vertically and horizontally at intervals is generally used. It is used. In the case of a wig base using artificial skin, shape retention is good, but breathability is poor and swelling occurs, while in the case of a wig base using a net, breathability is good,
The shape retention is poor, and the front part of the partial wig may be turned up especially during brushing, which is not preferable in terms of durability. Therefore, in order to prevent the front head from curling up, conventionally, the scalp and hair have been bonded to the back of the net with an adhesive or a double-sided tape. Therefore, the wearing and removing of the wig is extremely troublesome and the discomfort during use increases, and when the above-mentioned double-sided tape is used, the adhesive force is weakened by attaching and detaching the wig several times, and the double-sided tape must be frequently replaced.

In view of the above points, the present invention uses a net as a wig base and improves shape retention to produce a part wig having excellent durability without curling up in the forehead even during brushing or the like. It is intended to provide a way.

[Means for solving problems]

According to the present invention, the above object is to form a wig base net mold by coating a net-shaped male member on the head-shaped male mold along the contour of the head of the user, and the above-mentioned head-shaped male mold. After installing a molding die made of at least one metal thin plate of an appropriate shape at a predetermined position, a thermoplastic plastic plate that is softened by heating to a head-shaped male die from above the molding die is cooled and cured. And molding, and by cutting out the portion of the molded thermoplastic plate that was in contact with the thin metal plate, a mold made of a thermoplastic hard synthetic resin having a shape that matches the curved shape of the head. A part wig comprising the steps of forming a holding member, fixing the mold holding member to a corresponding outer surface position of the net mold, and implanting hair on the outer surface of the net mold. Achieved by the manufacturing method of .

The partial wig manufactured by this method is molded in conformity with the shape of the user's head at one or more predetermined positions of the base net mold molded in conformity with the shape of the user's head. Further, the mold holding member made of a thermoplastic plate having an appropriate shape is fixed, so that the shape holding property of the wig is improved, and the front head of the partial wig can be prevented from curling up during brushing or the like. .

Partial wigs produced according to the invention are preferably such that at least one of the pattern-holding members is along the direction in which the hair is raised in response to the hairstyle of the part-wig desired by the user, for example the leading edge of the partial wig. It is fixed from the vicinity to the rear or along the vicinity of the front edge. As a result, the shape-retaining property is further improved and the curling up can be prevented more effectively.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 (a) to 1 (g) are schematic views showing a manufacturing process of a partial wig according to the present invention. First, prior to molding the head-shaped male mold, a female mold in which the contour of the head of the user is copied is molded. At that time, as shown in FIG. Head-shaped female mold 1 directly molded from the head
By using, it is possible to manufacture a faithful head-shaped male mold.
As a female mold member, for example, a thermoplastic synthetic resin sheet having a thickness of about 1 to 6 mm is prepared, and this is stretched and held in the molding device 10 to be heated and softened, and then pressed from the top of the user's head to the vicinity of the lower ear, at room temperature. After cooling and hardening at, mark 11 so that the shape of the wig is planned. After the mold release agent is applied to the thus produced head-shaped female mold 1, the gypsum slurry is poured into the head-shaped female mold 1 to be hardened, and the head-shaped male mold 2 made of gypsum as shown in FIG. 1 (b) is obtained. Head-shaped male mold 2 molded in this way
Becomes an exact match with the user's head contour and can be significantly applied to the present invention. For details of the production of the female mold and the male mold, reference is made to Japanese Utility Model Publication No. 59-43366.

Next, the net base used in the present invention is manufactured on this head-shaped male die 2. The net material used at this time is usually made of nylon of 220 to 330 denier, but the net applicable in the present invention is not particularly limited thereto, and the thinner the fiber of the net is, the more the mold holding property becomes. Inferior,
Therefore, the effect of the present invention is further exerted. The head-shaped male die 2 is coated with a net material, and the net material is removed from the head-shaped male die 2 after temporary molding is performed by, for example, an epoxy resin solution dipping process, and the head of the user is ultrasonically welded. The wig base net mold 3 is obtained by molding into a shape (see FIG. 1 (c)). For an example of the method for forming the net mold 3, Japanese Patent Application No. 59-241614 (Japanese Patent Publication No. 3-55563) by the present applicant is referred to.

Subsequently, as shown in FIG. 1 (d), the process for manufacturing the mold holding member according to the present invention is started again using the above-described head-shaped male mold 2. An appropriate number of thin metal plates 5 such as copper plates and aluminum plates having appropriate shapes are installed at predetermined positions on the head-shaped male die 2. The metal thin plate 5 serves as a molding die for a die holding member, which will be described later, and is used by cutting it according to the size of the die holding member to be manufactured in advance.
At that time, for example, when the mold holding member is to be manufactured so as to extend rearward from the front edge of the partial wig, the thin metal plate 5 formed in a narrow elongated body is used to form the head-shaped male mold 2 as shown in the drawing. Just stick it on top. What is shown in FIG. 1 (d) is 3
The thin metal plates 5 are arranged so as to converge toward the rear from the front edge portion, and are closely fixed with a curvature matching the curved shape of the head-shaped male die 2. The thermoplastic plastic plate 6 which has been heated and softened from above is pressed, cooled and hardened to be molded, and then removed from the head-shaped male mold 2 (FIG. 1 (e)).
reference). At this time, the thermoplastic plate 6 is formed in a state where the metal thin plate 5 is brought into close contact with the surface of the head-shaped male die 2 by the pressing, so that the whole becomes the curved shape of the head-shaped male die 2 and the metal thin plate. In the region of 5, the thin metal plate 5
It is curved so as to project slightly outward by the thickness of. Here, a die holding member 7 (three in the illustrated embodiment) is obtained by cutting out the protruding portion of the molded thermoplastic plate 6, that is, the region of the metal thin plate 5.
The mold holding member 7 thus formed is shown in FIG. Both the short side 7a and the long side 7b substantially match the curved shape of the user's head.

Next, the mold holding member 7 is fixed to the position corresponding to the position of the metal thin plate 5 of the base net mold 3 by sewing or gluing to obtain the wig base 8. FIG. 1 (f) shows how the mold holding member 7 is attached to the wig base 8 and is fixed to the outer surface side of the base. Finally, a partial wig 9 is completed by implanting hair on the entire outer surface of the wig base 8 (see FIG. 1 (g)).

As the mold holding member 7, a thermoplastic hard synthetic resin material,
For example, a vinyl chloride resin having a thickness of about 0.1 to 0.5 mm is preferably used, and a resin colored in the same color as that of the net base or the scalp is preferably used.

The partial wig 9 manufactured in this way has good ventilation because the wig base 8 is made of a net member, and the mold holding member 7 extends slightly from the front edge of the partial wig 9 to the top of the head. Since the wig is attached so as to extend, the shape retention characteristic of the wig is good, and the frontal part of the head does not turn up even during brushing or the like.

The arrangement of the mold holding member 7 shown in the above-mentioned embodiment can be applied to hairstyles other than the side parts. In the case of the center part, the wig base is artificial in the peripheral area of the center mold holding member 7. It may be covered with the skin, or the central holding member 7 may be omitted or moved to another position. The third example of the preferable arrangement of the mold holding member 7 for various hairstyles is given.
This is shown in FIGS. FIG. 3 shows a back style, FIG. 4 shows a free bang, and FIG. 5 shows a center part. Here, in the example of FIG. 3 and FIG. 4, one of the mold holding members 7 is fixed so as to extend along the front edge of the partial wig, and the mold holding arranged in this way for each hairstyle. The member will hold the shape of the partial wig along the direction to raise and set the hair,
It is possible to more effectively prevent the front edge of the partial wig from curling up when brushing or the like. Furthermore, the applicant's Japanese Patent Publication
If used in combination with a fastening member according to 54-16785,
The mounting and fixing of the wig can be achieved more effectively.

〔The invention's effect〕

As is clear from the above description, the partial wig manufactured according to the present invention has good breathability because the wig base is made of a net member, and the shape of the head of the user is provided at a predetermined position of the wig base. Since the mold holding member molded together is fixed, the shape retention of the partial wig is improved and the front head can be effectively prevented from curling up even when brushing etc. (EN) A wig that is extremely comfortable to wear and has excellent durability because it eliminates the trouble and discomfort of having to adhere an adhesive or double-sided tape to the scalp.
