ABSTRACT:
Cloth for waterproof suits comprising a rubber waterproof layer in which circular or rectangular holes are formed at a population of 10 to 500 per ten square centimeters, a moisture-permeable waterproof polyurethane coating layer and two flexible cloth layers, wherein the moisture-permeable waterproof polyurethane layer is made in a wet process and a dry process and the opposite surfaces of the rubber waterproof layer each bind to the polyurethane layer and one of the flexible cloth layers through adhesive layers, the other flexible cloth layer being formed on the polyurethane layer. The adhesive layers may contain ceramic powder capable of emitting far infrared rays. The adhesive layers containing such ceramic powders, when elevating temperature or illuminating light, emits infrared rays, which are easily absorbed in organic materials, showing various profitable effects including deodorization as well as warmth-keeping, sterilization and anti-putrefaction. A waterproof suit made of the cloth has various profitable influences on the skin and prevents the bad odor attributable to sweat or moisture. After using, the waterproof suit can, even though remaining undried, prevent the propagation of fungi and bad odor. Therefore, it is very sanitary.
