Polytetrafluoroethylene (PTFF) has the characteristics of high temperature resistance, and it is also widely used in our lives. PTFF waterproof and breathable fabric was first developed for the production of military uniforms and protective clothing, and then used as sportswear. The main technical performance requirements of military raincoats are good waterproof and breathable functions and also light weight.
Fire-fighting clothing, the fabric is made of woven aramid cloth, the film is made of polytetrafluoroethylene, and the lining is made of warp-knitted aramid knitted fabric, which greatly improves the comfort of wearing protective clothing.
PTFE film material has the characteristics of corrosion resistance, strong acid, alkali resistance, and aging resistance, so PTFE laminated fabric can be used. Sleeping bags require warmth, breathability, and light weight. Based on the characteristics of PTFE micro porous membrane laminated fabric, it adopts a double-layer structure, with the outer layer of nylon fabric and the inner layer of PTFE membrane. There is no danger of hypoxia and carbon monoxide poisoning when using this sleeping bag. At the same time, application products such as polytetrafluoroethylene film can be developed.
Because PTFE material has excellent chemical resistance and flame retardant properties. And the micro porous membrane structure can more easily exert superior waterproof and air permeability. It has become an ideal material for the development of nuclear, biological and chemical protective clothing. The top fabric can fully meet the wearing needs of people during activities in harsh environments such as severe cold, rain, snow, and windy weather. It is also suitable for people's daily requirements for raincoats, shoes, etc., and has broad application and development prospects.
Conclusion: In the end, the focus of research and development of PTFE waterproof and breathable laminate fabrics is to reduce costs, and work hard towards making the fabric more lightweight, comfortable and multifunctional.
