The layer (layer) is a high-density polyethylene film which has been sufficiently stretched and reinforced, and which has been split into split fibers by making fine cracks, and which is continuously and thermally fused vertically and horizontally. In addition, this warif
It has strength, has gaps (through which water drops pass), and has no elasticity. For the third layer, a film having micropores is used. As the film, for example, a polyethylene film (or a nylon film or a vinylon film) is used. Then, the warif and the film are adhered with an adhesive to form a second layer and a third layer, and the first layer of taffeta is sewn to obtain a laminated material having three layers.

A waterproof, gas-permeable sheet body can be obtained by a simple method of forming micropores 5 having a conical cross section, which allows water vapor to pass outward but does not allow water droplets from the outside to the inside to pass through. In other words, the first-layer woven fabric can alleviate the water pressure component applied to the fine pores formed in the third-layer film, thereby improving the waterproof ventilation function. Eye) and the film (third layer) can eliminate puddles and prevent the entry of water droplets by the action of the surface tension of water in the conical micropores formed in the film (third layer). Of water vapor (molecules extremely small compared to water droplets). In other words, a pre-barrier (first layer) and a main barrier (third layer) are used in combination. The diameter of the fine holes in the first and third layers is made as large as possible to further enhance the ventilation function. Is also possible.
