Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a male mold for manufacturing a wig base. More specifically, the present invention relates to a method of manufacturing a male mold for manufacturing a wig base that can provide a wig with excellent dimensional stability and a good feeling of wearing.

Can be softened and molded by heating at relatively low temperatures,
A thermoplastic synthetic resin sheet that can harden while retaining its molded shape when cooled to room temperature is heated and pressed against the head to produce a female mold, and this female mold is filled with plaster to create a male mold. It is conventionally known to manufacture a wig base by molding a wig and applying a synthetic resin solution as a wig base coating to the molded male mold.

However, although molding a female mold using a thermoplastic synthetic resin sheet seems to serve the purpose of manufacturing a wig base that is easy to see and has good precision, the good thermoplasticity of the sheet may be an obstacle. However, there are cases where the objective cannot be completely achieved for the following reasons. The first reason is that the strength of the sheet when heated is not very high, and since it is stretched and thinned during molding, it cannot withstand the weight of the plaster, etc. used as the male M molding material, and it does not deform. Second, when pouring and curing plaster, there is a risk of softening and deformation due to the heat generated during curing.Therefore, it is necessary to increase the curing temperature of plaster during plastering to shorten the curing time. For example, if the temperature of the gypsum suspension is set to 80°C, it can be cured in a short time of about 2 to 3 minutes, but at this temperature, the delamination made of the sheet material becomes soft and does not form a WIl shape. Since it cannot support the weight of plaster, it is necessary to harden the plaster at a lower temperature for about 15 minutes.

The present invention has excellent dimensional stability without relying on such a method,
This relates to a method of manufacturing an electric layer for manufacturing a wig base that can provide a wig with a good feeling of wearing. This is done by applying a layer capping agent to the inner surface of the capped aS glue-like delamination, pouring the male shape material there, and curing it, then heating the molded male part from the female part. .

The female mold, which has the shape of the head, is molded using plaster, cast bandage, or other molding material. When the molding material is plaster, molding is performed as follows.

Stretchable films such as polyethylene, polyvinyl chloride,
Films such as polyvinylidene chloride, polyester, polybutadiene, generally having a thickness of about 1.51111 or less,
Preferably, a film of about 0.01 to 0.21 mm is covered without wrinkles, and the upper part of the ear part is pressed and fixed with a hat consisting only of the brim part. The prepared gypsum slurry is left to stand for 2 to 3 minutes to slightly increase the viscosity and then applied to the head film to a uniform thickness. At that time, the dripping gypsum slurry is stopped by the brim of the hat. After painting, wait for the plaster to harden for about 10 minutes.
The molded plaster mold is removed from the head and also separated from the film and the hat.

In the case of a cast bandage, soak it in water or hot water to absorb the water and soften it, squeeze it lightly onto the head film until it is still soft, and press it lightly with your hands so that the wrapped part is tied up well. , then wrap a second cast bandage in the same way, and spread it with your fingers to smooth the area where it was wrapped. A release agent such as solid paraffin, liquid paraffin, oil, etc. that does not penetrate into the female II molding material is applied, and then a male I molding material such as plaster is applied.
The carving material is poured.

The male mold that has been released from the female shoe has excellent delamination strength and no thermal deformation, so it faithfully copies its shape and has good dimensional accuracy, and is manufactured by applying wig base paint to it. The wig base also has good wearability. Also,
In the case of a plaster mold, the curing temperature can be raised up to 80° C., so it is possible to cure the mold in a short time of 2 to 3 minutes.

In this way, the MIU for wig base preparation manufactured by the method according to the present invention can faithfully copy the shape of the object to be attached to the wig, and therefore has excellent dimensional stability.
The present invention will now be described with reference to examples.

Example 1 A stretchable film (Fuji Film product Sealon film, thickness 0.11111
, size 400 x 500 sam), while stretching it slightly to avoid wrinkles, and fix the upper part of the ear part with a hat (trade name: Shampoo Hat) consisting only of the brim part. Gypsum (calcined gypsum) 18009 and water 1500
The slurry prepared by adding g and stirring is left for 2 to 3 minutes, and when the viscosity becomes a little high, it is applied to a uniform thickness on the film placed on the head. At this time, the dripping gypsum slurry is stopped by the brim of the hat.

It took about 10 minutes to harden after application. Remove the plaster delamination from the head and separate it from the film and the hat. Apply a thin layer of grease (silicon grease) as a mold release agent evenly to the inner surface of the female plaster mold thus formed. The same gypsum slurry as above was poured at 80°C. The curing time was approximately 2 minutes, and a male plaster mold was obtained by delaminating the curing bales.

By applying a wig base coating agent to the surface of this plaster delamination, a high quality wig base coating is formed.

Example 2 A film was placed over the head of the person performing the lid in the same manner as in Example 1, and the thickness was determined. After soaking the plaster-impregnated layer cast W in water for about 1 minute, it was squeezed gently. , while it is still soft, wrap it onto the film and press it lightly with your hand so that the wrapped area is fully tied. Wrap the second cast bandage over it in the same way, and use your fingers to smooth the border. Wet, spread, and wrap around the entire head. After about 10 to 15 minutes, when hardening is complete, remove the cast cast and separate from the film and hat.

A thin layer of solid paraffin was evenly applied as a mold release agent to the inner surface of the cast dressing molded in this way, and a gypsum slurry prepared by adding 1500 g of water to gypsum (calcined gypsum) 18009 was added to it at 80°C. and poured it. The curing time was about 2 minutes, and after curing, the mold was released from the female mold to obtain a male plaster mold. By applying a wig base coating agent to the surface of this stone ll1f male mold, a high-quality wig base coating is formed.
