DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wig base manufacturing method and a wig base, and more particularly to a wig base manufacturing method and a wig base made of a thermoplastic resin.

[0002]

2. Description of the Related Art Hitherto, as a method for producing a wig base using a thermoplastic resin, there has been known a method using a dopant obtained by dissolving a thermoplastic resin in an organic solvent. This is done by coating the dope on a mold having a head shape and coating the same, drying the organic solvent to form a thermoplastic resin film having a head shape, and using the thermoplastic resin film as a wig base. To use.

[0003] Although not commonly used in the manufacture of wig bases, a commonly used thermoplastic resin molding method is to heat a thermoplastic resin sheet processed into a sheet shape at a high temperature to soften it. There is a manufacturing method in which the mold is quickly pressed and fixed, removed from the mold after cooling, and formed into a shape following the mold.

[0004]

In the above-mentioned method of coating a dopant, the viscosity of the dopant increases as the concentration of the resin increases, and when air bubbles enter the dopant flowing on the mold at the time of coating, the resulting thermoplastic resin is formed. There is a problem that air bubbles remain in the film, and the thickness of the area where the air bubbles remain becomes thinner, and the strength as a wig base decreases and the appearance deteriorates. I couldn't. For this reason, there is a limit to the film thickness that can be formed by only one coating, and a resin that can be used as a wig base in one coating due to the problem of not being able to obtain a sufficient thickness and maintaining strength after forming the wig. The film could not be formed. Therefore, conventionally, a plurality of coatings of a doping agent were repeatedly performed to produce a wig base having a desired film thickness.

However, in this production method, it takes time and effort to dissolve a thermoplastic resin in an organic solvent or adjust the viscosity of a dopant to obtain a desired film thickness, and it is necessary to perform coating a plurality of times. Therefore, an intermediate step such as drying for each coating is required, and there is a disadvantage that it takes a long working time. Further, since the dopant contains an organic solvent, the worker must wear protective equipment such as gloves and a mask to perform the operation, which is troublesome. Furthermore, when using organic solvents, it is necessary to ensure a safe working environment for the protection of workers, and local exhaust equipment is installed at the work site, but the volatile organic solvents are completely removed. It is difficult to do so, and there is a problem that equipment cost is required for removal.

On the other hand, when the above-mentioned molding method using a thermoplastic resin sheet is used for molding a wig base, the thermoplastic resin sheet is heated at a high temperature and softened, so that the surface of the thermoplastic resin sheet becomes glossy. When molding into a head shape,
Due to the large size of the mold, the thickness of the thermoplastic resin film after molding varies, and there are problems such as partial thinning.When this is used for a wig base, the wig base becomes glossy and natural when attached. It is necessary to prevent the problem that the appearance of the wig is impaired and the appearance of wearing the wig is easily prevented, and the luster of the wig is prevented. I couldn't.

Accordingly, an object of the present invention is to provide a method of manufacturing a wig base which can provide a natural appearance and is easy to manufacture, and a wig base.

[0008]

According to a first aspect of the present invention, there is provided a method for manufacturing a wig, comprising the steps of stopping a thermoplastic resin sheet made of a urethane resin elastomer along a mold, heating, cooling, and releasing.

According to a second aspect of the present invention, in the method for producing a wig, the thermoplastic resin sheet is subjected to a matting process before the mold is fixed.

In a third aspect of the present invention, the thermoplastic resin sheet has a thickness of 0.01 to 0.5 mm.

According to a fourth aspect of the present invention, in the wig base for planting hair to form a wig, the wig base is formed from a thermoplastic resin sheet made of a urethane resin elastomer.

The wig base according to a fifth aspect is obtained by subjecting the thermoplastic resin sheet to a matting process.

In a wig base according to a sixth aspect, the thickness of the thermoplastic resin sheet is 0.01 to 0.5 mm.

[0014]

According to the first aspect of the present invention, since the thermoplastic resin sheet made of urethane resin elastomer is heated in advance after being fixed in the mold, the thermoplastic resin sheet is fixed to the mold with a constant thickness, and a part thereof is stretched and thinned. Thus, the thickness of the thermoplastic resin sheet can be made substantially uniform.
In addition, the temperature required for molding can be relatively low, unlike the related art. In addition, the elasticity of the urethane resin elastomer at room temperature (room temperature) facilitates attachment to the mold, and the molded wig base can be fitted exactly to the fitting portion at the time of fitting.

According to the second aspect of the present invention, the wig base after molding becomes matte, and the matte state can be maintained without gloss during molding.

According to the third aspect of the present invention, it is easy to attach the thermoplastic resin sheet to the mold, and it is possible to manufacture a wig having a good wearing feeling.

According to the fourth aspect of the present invention, the thermoplastic resin sheet made of a urethane resin elastomer can be preliminarily stopped in a mold and then heated to form a wig base having a mold shape.
Due to the elasticity of the urethane resin elastomer, attachment to a mold is facilitated, and the urethane resin elastomer can be fitted to a fitting portion at the time of fitting.

According to the structure of the fifth aspect, a natural appearance which is not recognized as a wig when worn can be obtained.

According to the sixth aspect of the present invention, the wig base has an excellent wearing feeling.

[0020]

Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 to 4 show one embodiment of the present invention,
In FIG. 1, reference numeral 1 denotes a thermoplastic resin sheet (hereinafter referred to as a resin sheet) having a thickness of about 0.01 to 0.5 mm and having elasticity. The resin sheet 1 is formed of a urethane resin elastomer. The surface is matte 1A and translucent, and a hairpiece (not shown) is planted to form a wig. 2 is a gypsum mold that forms the head of the wig wearer, and this gypsum mold 2 is, as shown in FIG.
A female mold 3 taken from the wearer's head is placed in an inverted state, a plaster 4 is poured into the female mold 3, and a paper stand 5 is inserted into the plaster 4, and the plaster 4 is removed. After curing, the female mold 3 is formed by removing the female mold 3. On the outer surface of the gypsum mold 2, a line 6 indicating the division and direction of the hair or the size of the wig base to be manufactured is described, and the outer surface is transparent. It is covered with a polyethylene sheet 7. In the figure, reference numeral 8 denotes a heating means such as an electric heater, and 9 denotes a substantially U-shaped metal staple having a width of about 10 mm and a height of about 5 to 20 mm.

The urethane resin elastomer used for the resin sheet 1 includes polycarbonate, ether,
Adipate type and the like are preferably used, and polycarbonate type is preferably used.

Next, a method of manufacturing a wig base using the thermoplastic resin sheet 1 will be described. The resin sheet 1 is attached to the gypsum mold 2 covered with a polyethylene sheet 7 so as not to be wrinkled or loose. A staple 9 is driven in and fixed by a staple driving device (not shown) at a position approximately two centimeters outside the necessary portion, thereby stopping the resin sheet 1 along the outer surface of the gypsum mold 2. In this case, due to the elasticity of the resin sheet 1, the resin sheet 1 can be stuck along the outer surface of the gypsum mold 2 without being loosened, and can be stuck without extending a part thereof. The entire periphery of the resin sheet 1 is fixed to the gypsum mold 2. Next, the resin sheet 1 is fixed to the gypsum mold 2 by the heating means 8 or the like.
Is, for example, 60 to 140 degrees, preferably 100 to 120 degrees.
The temperature is, for example, 1 to 24 hours, preferably 4 to 8 hours. After this heating, the resin sheet 1 is naturally cooled to room temperature in a room at room temperature, whereby the resin sheet 1 is formed along the shape of the gypsum mold 2. Here, if necessary, the line 6 described on the gypsum mold 2 is copied to the resin sheet 1. In this case, since the resin sheet 1 is translucent, the line 6 can be copied while attached to the gypsum mold 2. . Then, the resin sheet 1 is removed from the mold together with the staple 9, and an unnecessary portion is cut out to obtain a wig base in the shape of the wearer's head.

As described above, the present embodiment is a method of manufacturing a wig base in which the thermoplastic resin sheet 1 made of a urethane resin elastomer is stopped along a mold, heated, cooled, and released. A wig base having a desired uniform thickness can be easily manufactured simply by stretching the sheet 1 into a mold. In addition, compared to the conventional method of coating a doping agent, an intermediate work step such as a complicated coating operation and accompanying drying is not required, so that the operation time can be reduced, and the doping agent is used. Since there is no need, there is no harm caused by the use of an organic solvent, the working environment can be maintained well, and the worker can work without wearing protective equipment such as a mask, and can work smoothly and safely. In addition, equipment such as local exhaust is not required, and costs such as equipment costs can be reduced. In addition, in the conventional manufacturing method of softening the thermoplastic resin sheet and pressing it against the mold, a high temperature is applied when the thermoplastic resin sheet is softened, so the elongation partially increases and the thickness of the wig base increases. Variations were caused, and it was partially thin or glossy due to the pressing and heating, but in the present invention, it can be fixed to the mold while having a certain degree of strength, and a part does not stretch In addition, the resin sheet 1 can be formed with the thickness being substantially uniform, and can be formed with a relatively low heating temperature.
If the matting process is performed on the resin sheet 1 in advance, the matte state can be maintained until after molding. Moreover, since the thermoplastic resin sheet 1 is made of a urethane resin elastomer, the elasticity of the thermoplastic resin sheet 1 makes it easy to attach the resin sheet 1 to the gypsum mold 2, and it can be attached easily with almost no wrinkles or looseness.

As described above, in this embodiment, the thermoplastic resin sheet 1 is subjected to the matting process 1A before the mold is fixed.
There is no need to apply matting after the wig base is formed, and a matte wig base can be obtained.

As described above, in this embodiment, 0.01 to 0.01
By using the thermoplastic resin sheet 1 having a thickness of 0.5 mm, the attachment of the resin sheet 1 to the gypsum mold 2 becomes easy, and the feeling of wearing the completed wig base is improved.

Further, as described above, in this embodiment, in the wig base in which hair is implanted to form a wig, the wig base is formed from the thermoplastic resin sheet 1 made of a urethane resin elastomer. The thermoplastic resin sheet 1 is preliminarily fixed in a mold and then heated to form a wig base having a mold shape, and the elasticity of the thermoplastic resin sheet 1 facilitates attachment to the mold, and also allows mounting. The feeling is excellent.

Further, as described above, in this embodiment, since the matte is applied to the thermoplastic resin sheet 1 made of a urethane resin elastomer, a natural feeling which cannot be recognized as a wig at the time of wearing is obtained.

Furthermore, in this embodiment, since the thickness of the thermoplastic resin sheet 1 made of a urethane resin elastomer is 0.01 to 0.5 mm, a wig base excellent in wearing feeling can be obtained.

As an effect of the embodiment, the use of the thermoplastic resin sheet 1 made of a polycarbonate-based urethane resin elastomer makes it possible to set the heating temperature because the range of the softening temperature and the melting temperature is wider than those of the others. And the management is easy, and the wig base obtained after molding has almost no change in appearance due to yellowing,
Moreover, the thickness of the wig base obtained after the molding has little variation, and the wig base after the molding has excellent shape retention, and it is said that the wig base has excellent stability in processes such as flocking after molding. Have advantages.

As an effect of the embodiment, the use of the gypsum mold 2 makes it possible to easily and inexpensively produce a mold having a different head shape for each person. Compared with the gypsum mold, even when heated with the resin seal 1 stopped, the gypsum mold 2 has almost no deformation such as thermal expansion.

Further, by using the staple 9, the resin sheet 1 can be easily stuck to the gypsum mold 2, and the work of peeling off the gypsum mold 2 becomes easy. 1 is a plaster mold 2
The resin sheet 1 can be reliably stopped without peeling from the resin sheet.

Further, since the resin sheet 1 is not melted by heating at a temperature of 60 to 140 degrees, preferably 100 to 120 degrees, the resin sheet 1 is stably formed in a plaster mold 2 with a uniform thickness. In addition, since the resin sheet 1 is heated at a relatively low temperature, the generation of gloss due to the heating is eliminated.

The heating is carried out for 1 to 24 hours, preferably 4 hours.
By performing for up to 8 hours, the resin sheet 1 can be formed into the shape of the gypsum mold 9 in an optimum time.

Since the resin sheet 1 is translucent,
In a state where the resin is overlaid on the gypsum mold 2, for example, the line 6 described on the gypsum mold 2 can be copied onto the resin sheet 1.

It should be noted that the present invention is not limited to the above embodiment, and various modifications can be made within the scope of the present invention. For example, the wig base can be made of various materials as long as it is a thermoplastic resin sheet having elasticity. Although the embodiment uses a heating means such as an electric heater, the heating means may be housed in a heating chamber such as an electric oven for heating. Furthermore, plaster mold 2
A silicon film formed by applying a silicone agent may be used as a material that covers the outer surface of the device, or a mold of various materials such as wooden or resin may be used in place of the plaster mold. In order to fix the thermoplastic resin sheet to the mold, various fixing means such as rubber bands and clips can be used in addition to the staples shown in the embodiments.
