The working principle of PE waterproof tarpaulin
Waterproof tarpaulin is a new type of textile fabric, which is composed of polymer waterproof and breathable materials and Oxford cloth. The main functions of waterproof and breathable fabrics are: waterproof, moisture permeable, breathable, insulating, windproof and warm.
In terms of production process, the technical requirements of waterproof and breathable fabrics are much higher than that of ordinary waterproof fabrics; at the same time, from the perspective of quality, waterproof and breathable fabrics also have functional characteristics that other waterproof fabrics do not have. The waterproof and breathable fabric enhances the air-tightness and water-tightness of the fabric, and at the same time, its unique vapor-permeable performance can quickly discharge the water vapor inside the structure, prevent the structure from breeding mold, and keep the human body always dry, which perfectly solves the problem of ventilation, windproof, waterproof, It is a new type of fabric that is healthy and environmentally friendly.
In the state of water vapor, the water particles are very small and can smoothly penetrate into the capillary to the other side, so that the phenomenon of vapor permeation occurs. When the water vapor condenses into water droplets, due to the surface tension of the water droplets, the water molecules cannot smoothly escape from the water droplets and penetrate to the other side, preventing the infiltration of water and making the vapor permeable membrane waterproof. The wide use of tarpaulin can protect goods or various materials from the baptism of rainwater, effectively waterproof, rainproof and waterproof, which brings great convenience to people.
