We all now know that the three-layer principle of outdoor clothing is the inner layer to wick away sweat, the middle layer to keep warm, and the outer layer to be waterproof and breathable. This started spreading widely online very early on. The principle is nothing more than that the inner layer uses the sweat-wicking layer to bring the sweat from the body to the outer layer. The outer layer can also block the entry of external water vapor, and when it is cold, the middle layer keeps warm. I haven’t had time to write for a long time. I saw that many friends just copied everything without understanding the principles of dressing. I would like to briefly introduceePTFEClothingFabric strong>and correct some traditional mistakes of the past.
Water repellency means that water on the outside of the fabric will not penetrate the fabric and soak into the inside. ePTFE clothing fabric is still water-repellent even under 80lb/m2 pressure. When wearing this fabric, people will not feel wet even if they stand in a storm or sit on a wet surface. The reason why this fabric garment has such powerful functions is mainly because the micropore diameter of the PTFE membrane of the main body of the fabric is 1/5000-1/20000 of the diameter of water droplets, so even very small raindrops cannot pass through. The surface energy of PTFE is low, and water droplets cannot spread on the film, preventing water droplets from penetrating.
ePTFEClothingFabric is prepared using special two-way stretching technology Obtained, it can ensure that all impurities such as small bacteria are trapped, and at the same time it has a large flux. The material has the characteristics of temperature resistance, resistance to strong acids and alkali, and wide chemical applicability. When used for gas filtration, it can intercept all kinds of phages, small bacteria and particles above 0.02um. PTFE microporous membrane has a very high filtration efficiency and can meet the filtration efficiency level requirements of sub-grade air filters.
