The three-layer fabric of ptfe composite material has functions such as waterproof, breathable, and windproof, which greatly improves the comfort and functionality of sportswear. The specific performance is as follows: 1. Waterproof performance: The fabric of the ptfe composite material The reason why it has such excellent function is mainly because the micropore diameter of the main PTFE membrane of the fabric is 1/5000-1/20000 of the diameter of water droplets, so even the smallest raindrops cannot pass through. The surface energy of the PTFE membrane is low and water droplets cannot pass through it. Spread on the film, thus preventing water droplets from penetrating.
2. Air permeability: The porosity of ptfe composite materials can be as high as 80%, and the average pore diameter is 0.2um, thus ensuring good air permeability.
3. Windproof performance: During the stretching process, the ptfe film forms a microporous structure in which nodes are connected to countless microfibers. Pores are formed between the microfibers, and the pores penetrate each other to form a unique network structure. The wind cannot directly When it passes through, it will change direction and turn back when it encounters an obstruction, effectively preventing the penetration of air, so it has excellent windproof performance.
4. Warmth insulation performance: PTFE membrane has excellent moisture permeability and can promptly transmit the steam emitted by the human body to the outside. Tests have shown that the fabric warmth retention effect of PTFE composite materials is 30% to 40% higher than that of traditional down jackets. .
