Problems solved by technology

[0002] At present, the elastic waterproof fabrics used in the market mostly use polyester resin PU fabrics, that is, the surface of the elastic fabrics is covered with a layer of PU plastic coating. This fabric is widely used to make water sports clothing, such as swimming caps and swimsuits. Although the products made of this kind of fabric can meet the requirements of waterproof and sealing, they have obvious defects. One is that the polyester resin PU coating is easy to age and separates and falls off from the fabric layer, which shortens the service life of the product. Reduce and make the product lose water resistance. Second, it will cause obvious discomfort to the user. Third, the drainage and extensibility are not as good as silicone rubber products. However, pure silicone rubber products will directly contact the body surface when worn, and will suffer from poor air permeability. It makes the user feel uncomfortable, and at the same time, it is easy to tear when it touches a sharp object.

Abstract

An elastic waterproof cloth is composed of silicon rubber layer on one surface of cloth and adhesive layer between cloth and silicon rubber layer. Its production process includes coating liquid silicon rubber on carrier for having it vulcanized, brushing adhesive on surface of silicon rubber, sticking elastic cloth on silicon rubber surface and separating carrier from elastic cloth. A device for realizing the production process is also disclosed.
