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) plus fabric composite fabric or reinforced with waterproof agent for waterproofing.

Why waterproof fabric can be waterproof

At present, many mattress fabrics are not waterproof, only a small amount of water dripping on the mattress will soon penetrate into it, providing a good living environment for bacteria and mites. This will not happen to waterproof fabric mattresses, which can reduce the breeding of bacteria and mites.

The principle is that in the state of water vapor, the water particles are very small. According to the principle of capillary movement, the capillary smoothly permeates to the opposite side, and vapor transmission occurs. When water vapor condenses into water droplets, the particles become larger. Due to the surface tension of the water droplets (the water molecules "pulling each other") and due to the effect of the surface tension of the water droplets (the water molecules "pulling against each other"), the water molecules cannot smoothly escape from the water droplets and penetrate to the other side, which is to prevent In order to prevent the penetration of water, the breathable membrane has a waterproof function.

This principle seems a bit complicated. To put it simply, the mattress has a waterproof and breathable membrane to prevent water from penetrating into the mattress. In addition, another method is to use a waterproofing agent for treatment, the surface will form a waterproof layer, which can prevent water from quickly penetrating into the mattress. The fabric treated with a waterproofing agent is a waterproof fabric.
