The waterproof non-woven fabric(Hot Air Through Nonwoven Fabric On Sale) can be waterproof and prevent some tiny bacteria from the outside world. Now the market prospect is still good. Waterproof fabric is a new type of textile fabric. Its composition is made of polymer waterproof and breathable material (PTFE membrane) plus fabric composite fabric. The main functions of waterproof and breathable fabrics are: waterproof, breathable, breathable, and insulating. In terms of production process, the technical requirements of waterproof and breathable fabrics are much higher than that of general waterproof fabrics. At the same time, in terms of quality, waterproof and breathable fabrics also have functional characteristics that other waterproof fabrics do not have. Under the condition of water vapor, the water-repellent non-woven fabric(China Hot Air Nonwoven Fabric Vender) has very small water particles. According to the principle of capillary movement, it can penetrate into the capillary to the other side smoothly, so that the phenomenon of vapor permeation occurs. When the water vapor condenses into water droplets, the particles become larger. Due to the surface tension of the water droplets, the water molecules cannot escape from the water droplets and penetrate to the other side, which prevents the penetration of water and makes the vapor permeable membrane. Waterproof function.

Through the above description, do you have a new understanding of why hot air non-woven fabrics are so waterproof? I believe that with the development of society, non-woven fabrics will have more room for development and are familiar to more people.
