The demand for synthetic fibers is not limited to clothing, but is also used for various industrial materials, but the melting point of synthetic fibers such as polyamide and polyester is generally 200 to 300°C, so the demand for clothing and industrial materials made from these synthetic fibers is In the process of use, material products melt and open pores due to heat compared to natural fiber materials, and encounter various problems caused by heat.

In addition, general waterproof products such as coats and awnings do not allow rain to pass through, but they also do not allow air or water vapor to pass through, and there is a problem that they become stuffy when worn or used.

For this reason, ■ a method in which a microporous 4-fluoroethylene film is laminated on a fabric, or ■ a method in which fillers and solvents that are very easily eluted in water or special solvents are added to a resin solution mainly composed of polyurethane elastomer, which is generally called the wet method. After applying it on the fabric, it is passed through a special solvent tank and hot water washing tank in an undried state.The filler and solvent are eluted and a microporous resin film is created. moisture,

However, the disadvantages of products produced by these methods are that if emphasis is placed on film performance, the peel strength of the film will be weak; if emphasis is placed on peel strength, the adhesive will inhibit air permeability and moisture permeability, and the product's texture will be rough and hard. In case (2), the shape of the pores in the resin film generated when the filler solvent is eluted tends to have a columnar structure with respect to the film layer, such as vertically elongated or vertically cracked pores, which tends to cause defects in its waterproof performance.

In addition, moisture permeability is achieved using a so-called dry method, which uses a resin mainly composed of polyurethane elastomer that has moderate moisture absorption.
Although waterproof fabrics have been manufactured, there is an upper limit to the thickness of the resin coating in order to maintain its performance, which naturally results in the disadvantage that the surface coating becomes weak.

In general, silicone rubber films have potential gas permeability and moisture permeability, but this is further enhanced by the discontinuous arrangement of fillers with hygroscopic and water-retaining functions in the resin film. Due to the stepwise and continuous vaporization effect caused by the temperature difference between the organic solvent and the sublimable substance that vaporize from the film, micropores with various shapes such as columnar, spherical, and elliptical shapes are formed in the silicone rubber film layer. It is thought that each of these contact holes has a microscopic contact point.

Another factor is that silicone rubber undergoes a dehydrogenation condensation reaction due to heat treatment=Si-OH+H-8i=→=St
