What is tarpaulin made of?

Tarpaulin is a waterproof material with high strength, good toughness and softness. It is made of polymer waterproof and breathable material, often cloth such as canvas or polyester coated with polyurethane, or made of plastics such as polyethylene. 

The main functions of waterproof and breathable fabrics are: waterproof, moisture permeable, breathable, insulated, windproof and warm. Often used as canvas (canvas), polyurethane coated polyurethane or made of polyethylene plastic. Tarpaulins usually have a strong grommets at the corners or edges for easy strapping, hanging or covering.

From the production process, the technical requirements of waterproof and breathable fabrics are much higher than those of ordinary waterproof fabrics. At the same time, from the perspective of quality, waterproof and breathable fabrics also have functional features not available in other waterproof fabrics. The waterproof and breathable fabric enhances the airtightness and watertightness of the fabric, and its unique steam permeability can quickly discharge the water vapor inside the structure, avoiding the structure of mold and mold, and keeping the body always dry, perfectly solving the ventilation and windproof, waterproof, The problem of keeping warm is a new type of fabric that is healthy and environmentally friendly. So what is the working principle of waterproof tarpaulin:

In the state of water vapor, the water particles are very small, and according to the principle of capillary movement, the capillary can be smoothly infiltrated to the other side, thereby causing vapor permeability. 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 smoothly escape from the water droplets and penetrate into the other side, that is, the penetration of water is prevented, so that the vapor permeable membrane has waterproof function.
