What are the properties of products made by tarpaulin manufacturers?

Tarpaulin manufacturers should consider the following performance indicators of tarpaulins when designing or using specific products. 1. Air permeability: The tarpaulin must consider its air permeability. Especially for military tent fabrics, the factors affecting air permeability include base fabric arrangement, density, material, type of waterproofing agent, resin adhesion, etc. With the increase of resin adhesion, the air permeability of the tent decreases. It is related to the cleaning agent. Generally, most of the tents with air permeability are made of cotton, vinylon, lacquer and other short cotton fabrics that are cleaned by paraffin or acrylonitrile resin. 2. Tensile strength: The tarpaulin must withstand various tensions during use, such as tension when it is fixed, and additional forces such as wind, rain, and province during use, although it is subject to these external forces. , still requires them to maintain the original shape and not easily deformed, which requires the tarpaulin to have a high tensile strength, and there should not be too much difference in the tensile strength of the warp and weft. In particular, the tensile strength of large tents used as inflatable buildings is extremely important. Generally, the base fabric is made of high-strength polyester, vinylon and other long-fiber fabrics, which are waterproofed by vinyl chloride resin and chlorosulfonated polyethylene resin. It is mainly determined by the strength of the fiber material and the density of the fabric. 3. Elongation skin and dimensional stability: As eaves tents and large tents, they are often used under tension. The elongation of the fabric should not be too large, and its dimensional stability is determined by the creep characteristics of the material. 4. Tear strength: The damage of the tarpaulin is mainly caused by tearing, so the tear strength is an important indicator of the tarpaulin. The tear strength is related to whether the tarpaulin will break due to the effect of flying foreign objects or for some reason in the formation of holes.
