what is water-resistant fabric?
what kind of water-resistant fabric ?
1.gore－tex
Gore tex has a very high performance in waterproof and breathable aspects. Its essence is a very thin layer of expanded polytetrafluoroethylene film, which is then placed on the fabric in a sandwich way to form high-quality waterproof fabric. Its characteristic is that there are about 1.4 billion small holes per square meter, and the area of each hole is only one twentieth of that of small water droplets, so the air permeability is very high and water droplets will not pass through.
2.Dry－Tec
The advantage of waterproof cloth compared with waterproof fabric is that it is extremely light and cool. Because the bottom layer is a layer of extremely tough film to withstand water pressure, and the center is a highly breathable layer with large pores. Its folding volume is very small and its weight is light, so it is often used to make waterproof clothes for sports.
3.PVC coated cloth
Its main ingredients are polyvinyl chloride. During the manufacturing process of PVC canvas, some auxiliary materials such as plasticizer and anti-aging agent are added to enhance its heat resistance, toughness, ductility, etc. The surface is coated with paste resin and added with a variety of chemical additives such as accelerator, mildew inhibitor, anti-aging agent, etc. It has non flammability, high strength, climate change resistance and excellent geometric stability, and also has waterproof, mold proof, wear-resistant, durable, cold resistant Aging resistance, etc.
