Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a wig base, that is, a wig body to which flocking is applied.

The conventional manufacturing method for wig bases uses a flexible synthetic resin film such as vinyl film and adhesive tape. First, the head is covered with the flexible synthetic resin film, and then the head is wrapped with adhesive tape.
Next, adhesive tape is applied to the entire surface, a mold is made, this is used as a female mold to obtain a male mold, and a rubber film or synthetic resin film is formed on this surface and then peeled off to obtain a wig base. There is a drawback that an accurate wig base cannot be obtained due to shrinkage of the materials, namely the flexible synthetic resin film and the adhesive tape.

The present invention was made to eliminate these drawbacks, and it is possible to obtain a wig base that perfectly fits the user's head.

That is, the present invention involves the process of heating a thin thermoplastic synthetic resin plate that can be softened and molded at low temperatures and hardening when cooled to room temperature, pressing it against the head, cooling it and hardening it to obtain a female mold. The production of a wig base is characterized by the steps of: filling the female mold with plaster to obtain a male mold; and applying a flexible synthetic resin material to the male mold and drying it to obtain a wig base. The purpose of this method is to easily obtain a wig base that fits the user's head.

The thermoplastic synthetic resin thin plate used in the present invention, which can be softened and molded at low temperatures and hardens when cooled to room temperature, is preferably a trans-type polyisoprene sheet having a thickness of about 2 to 3 mm.

In addition, the plaster used to make the male mold should be one with super hardness and good dimensional accuracy, such as dental super hard plaster.

In addition, when making a wig base using a male plaster cast, the wig base is coated with a mold release agent to prevent plaster from sticking to it during peeling.The mold release agent is silicone or a soft coating. .

Next, an embodiment of the present invention will be described. As shown in FIG.
is stretched and held on one side by a frame 4 which is connected so as to be openable and closable with hinges 3a and 3b, and this is held on an electric heater board (not shown) and heated, and after about 3 minutes, the milky white color becomes transparent. Once the material has softened and cooled until it is not hot to the touch with the back of your hand, hold the frame 4 with both hands and press it against your head, and hold it until it cools down (about 7 minutes) until the material returns to its original milky white color. The female mold A shown in FIG. 2 is obtained by removing the wig from the head, and marking lines 5 are marked with ink on the swollen portion of the female mold A at the necessary portions of the wig base.

Next, low-expansion, high-hardness, high-strength gypsum was added to the inner surface of this female mold A by dispersing the gypsum little by little in a container containing 100 g of gypsum and 25 c.c. of water. Stir for 15 minutes, spread a small amount thinly, and then gently fill in the rest. At that time, insert the 6 ends of the support into the center, and after about 15 minutes, that is, before reaching the maximum temperature, remove the female mold A. After removing it and waiting for it to finish setting, it was placed in a dryer and cured to obtain a male plaster mold B. This was placed on a support 6 and placed on a base 7 in a hemispherical recess 8 on the upper end surface of the base 7. A sphere 9 formed at the end of the column 7 is fitted and fixedly supported by a cap 10 so as to be tiltable. A suction cup 11 is attached to the lower surface of the base 7 to fix it on the flat surface of the workbench.

Next, a mold release agent such as a fluorine resin is sprayed on the surface of the male mold B in advance using a spray gun, dried, heat treated, a wig base material such as urethane synthetic resin is applied, and the mold is heated and dried in a conventional manner. A wig base 12 is obtained by peeling.

The wig base obtained in this way yields a male mold that is faithful to the original shape and has almost no deviations, so the wig base obtained from the male mold obtained based on this can be used to create a wig by implanting hair, and then wearing it. It has the characteristics that it fits well on the head, makes it possible to obtain a wig that feels good, and that it is extremely easy to make a female mold.
