Waterproof fabric-literally means to prevent water from permeating from one side of the fabric to the other. It is a new type of textile fabric, its composition is made of polymer waterproof and breathable material (PTFE membrane) and cloth composite fabric.
Why can it be waterproof?
Nowadays, many mattress fabrics are not waterproof. Only a little bit of water stains stick to the mattress, which will penetrate into it after a while, providing a good living environment for bacteria, mites, etc. As for waterproof fabrics, there will be no such situation. Its principle is that in the state of water vapor, the water particles are very small. According to the principle of capillary movement, they can smoothly penetrate the capillary to the other side, thereby causing vapor transmission. When the water vapor condenses and turns into water droplets, the particles become larger. Due to the surface tension of the water droplets (the water molecules "pull against each other"), the water molecules cannot smoothly escape from the water droplets and penetrate to the other side, which is to prevent The penetration of water occurs, so that the breathable membrane has a waterproof function.
