PTFE fabric is made of polytetrafluoroethylene membrane by special technology and ordinary fabric lamination. The fabric integrates the excellent waterproof and moisture-permeable properties of the PTFE membrane, so that sweat vapor can quickly leak out of the fabric, and the human body will not feel stuffy. Therefore, it is the top waterproof and breathable material at this stage.
In addition, because the holes are extremely small and the longitudinal irregularities are arranged in a curved arrangement, the wind cannot pass through. As a result, it has the characteristics of windproof and good warmth retention. Special treatment on the polytetrafluoroethylene membrane greatly improves its firmness and durability. After being compounded with other fabrics, it is widely used in military clothing, medical clothing, casual clothing, fire protection, biochemical protection, anti-virus, water immersion operations, outdoor sportswear, shoes, hats, gloves, sleeping bags, tents and other materials.
The polytetrafluoroethylene film has excellent moisture permeability, which can timely transmit the steam discharged from the human body to the outside of the microclimate, prevent the water vapor from condensing into liquid water, and reduce the possibility of water conduction heat. Although the surface of the PTFE membrane is densely packed with a large number of micropores, the wind cannot penetrate, so it can effectively prevent air convection. Tests show that in a strong wind of 25m/s, the thermal insulation effect of the laminated fabric is 30-40% higher than that of the traditional down jacket.
From 1982 to 1983, Japanese mountaineers wore PTFE composite fabrics and climbed the mountains at an altitude of 8,000 meters. The clothes withstood the test of severe weather conditions of -30℃ and wind speed of 30m/s. The athletes did not have any frostbite and returned safely.
