Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a porous surface and a method for producing the same.
I do it. More specifically, we will discuss a wig base made of a porous synthetic resin coating and a method for producing the same.

Conventionally used wig bases are made of a synthetic resin coating and do not have any special pores, so they have very poor breathability.
Not good from a hygiene standpoint.

To avoid these drawbacks, net-type wig penises with sufficient air permeability are also used, but these have the following disadvantages.

(1) Since the hair is tied to the net itself, there is a limit to the number of strands, and the wig as a whole lacks fullness. (2) If you style your hair at <L, the comb may get caught in the eyes of the net. Easy (3) When viewed from above, it may look a bit off (,)
Since the hair is implanted with the lining material and the hair cannot be fixed, the knot is unstable, unsteady, and easy to pull out (5) 7, □=””
The present invention is made of a porous synthetic resin coating and has a net of 9.
It is an object of the present invention to provide a wig base and a method for preparing it which do not have the disadvantages of type K and are excellent in terms of breathability.

Therefore, the present invention relates to a porous wig base and a method for producing the same. A synthetic resin solution containing a water-soluble substance is applied to the shoe as a coating agent, and after preferably semi-drying the coating, the Sokura body is immersed in an aqueous medium to extract the water-soluble substance in the formed film. After that, the entire lid is heated and dried, and then the coating is peeled off from the male part.

The details of the method for manufacturing the porous wig base will be described below.

In this manufacturing method, first, a synthetic resin solution containing a water-soluble substance is applied as a coating onto the aSS-like mm. As the synthetic resin, resins having rubber-like elasticity such as polyurethane, soft polyvinyl chloride, vinyl chloride-urethane, and silicone are generally used. t&, as a solvent,
Dimethylformamide, methyl imbutyl ketone, methyl ethyl ketone, ethyl acetate, butyl acetate, etc. are used alone or in combination. When this synthetic resin solution is used as a coating agent, in addition to the water-soluble substances described below, pigments can be added to give the desired color. It is first degassed under reduced pressure.

The water-soluble substances contained in the synthetic resin solution include sodium chloride, potassium chloride, calcium chloride,
Water-soluble inorganic salts such as quaternary ammonium salts, starch, vegetable gums, alginic acid), natural icy polymer substances such as IJum, gelatin, and casein, and semi-synthetic water-soluble substances such as methylcellulose, ethylcellulose, carboxymethylcellulose, and bitroxymethylcellulose. polymeric substances,
Synthetic water-soluble polymer substances such as polyvinyl alcohol, polyvinyl methyl ether, vinyl methyl ether-maleic anhydride copolymer, polyvinyl pyrrolidone, polyvinyl sulfonic acid, polyacrylic acids, polyacrylamides, polyethylene oxide, polyethylene imine, etc. This is a typical example. These water-soluble substances are generally crosslinked with an opening of about 5 to 60%, based on the weight of the synthetic resin solution as coating component, depending on the desired porosity.

Coat the synthetic resin solution containing the water-soluble substance onto the m board.
This is done using a brush or the like to a thickness of approximately one inch, but in this case, it is generally done directly on the m1it, which is made of plaster or the like.
*When the agent is applied, O from the formed coating film oxaxii
There are various problems with peelability, etc., so heat and soften a synthetic resin sheet such as a polyethylene sheet with a thickness of about 1 to 0.5 m in advance so that there are no wrinkles or curls. It is preferable to rub the sheet and apply a Kll agent on the sheet to test the releasability.

9. The wig base is made of synthetic resin coating only.
However, it is also possible to use delicate materials that are inert to the paint, such as nylon fibers, multifilaments, or conjugates of these materials.
Cover the male mold with a thin cloth directly or through the plastic sheet without wrinkles or sagging, and
Preferably, mF M is applied to produce a wig base reinforced with thin fabric.

Furthermore, the application of one coat is generally applied over the entire surface onto the male mold, but it can also be applied partially, in which case the remaining areas are coated with a synthetic resin solution, preferably without water-soluble substances. It is also possible to partially strengthen the porous film, which is somewhat inferior in strength, by applying a solution of the same type of SO synthetic resin as that used to form the coating.

After applying the paint in this way, the male mold is coated with a synthetic resin coating, preferably left at room temperature for about 5 to 30 minutes to semi-dry. Soak in aqueous medium for about 1-6 hours. The water-soluble substances contained in the coating exist without being dissolved in the synthetic resin solution,
At this stage, it is extracted with an aqueous medium to form a completely or partially porous synthetic resin coating.

As the aqueous medium used for extraction, water is preferably used alone, but water and a water-soluble solvent such as dimethylformamide, dimethyl sulfoxide, dimethyl acetamide, aptane, alcohol, methyl ethyl ketone, methyl isobutyl ketone, etc. O61 & gold solvents can also be used. These O aqueous media are generally #5 to 90t
It is preferably used at a temperature of about 40 to eo'cON degrees, and the extraction effect is not sufficient below this temperature.

After 70 days, the entire body taken out of the aqueous medium was heated and dried at about 0°C, and the coating was peeled off from a physical standpoint. It is also possible to further increase the porosity by subjecting it to an extraction operation using an aqueous medium again.

In this way, the porous wig base, which is formed by providing KJI agent holes entirely or partially in the synthetic resin coating, has appropriate strength and has a 4-star rating in terms of texture and breathability. It has the sufficient effect that there is no

Next, the present invention will be explained with reference to % Examples.

Example 1 An organic solvent bath aK of polyurethane resin 11, 30% starch and a desired OIk material αf% based on the weight of the resin are respectively added and thoroughly mixed, and the mixture is defoamed under reduced pressure to form a coating material.

A polyethylene sheet (thickness approx. 3 m) heated and softened with hot plaster is pressed onto the male plaster mold of the head shape that has been made, and stretched sufficiently to avoid wrinkles or sagging. The lower part of the mold is fixed with a rubber band, and then a thin fabric is covered and fixed in the same way without wrinkles or sagging. Approximately 111118 when brushed on thin fabric! Wire the cloth evenly to the desired thickness. After leaving it at room temperature for about 10 minutes, put it in a hot water bath at 50-60℃.
The whole 161 is soaked for about 1 hour to extract the starch. After extraction, the entire mold was dried in an oven at 80° C., washed with water again, dried, and then the formed film was peeled off from the plaster mold. Appropriate strength: A porous wig base with satisfactory stiffness, texture and breathability was obtained.

In Example 4 In Example 1, salt was substituted for starch (Example a),
For sodium alginate (Example S) 19, methylcellulose (Example 4) was used in an amount of 10% based on the weight of the resin. In both cases, porous wig pastes were obtained that were satisfactory in terms of a suitable level of 1W and air permeability.

Example 6 In Example IK, a mixture of dimethylformamide and water in equal parts was used as an extraction bath. Quality wig pace was obtained.

The thickness, texture and feel of the wig pastes obtained in each of the above Examples were measured or evaluated as shown in Table 7 below.
