Tensile strength: When using tarpaulin have to endure all kinds of tension, such as fixed under tension when tightened to: the course is subject to an additional force of the wind, rain, and other provinces. Despite these forces, still requiring them to maintain the original shape, not easily deformed, which requires tarpaulin has a higher tensile strength, and should not have too much difference to the tensile strength of the warp and weft. Especially as building large inflatable tents tensile strength is extremely important. Usually the bottom fabric with high strength polyester, polyvinyl alcohol and other long fiber fabrics by the vinyl chloride resin, chlorosulfonated polyethylene resin waterproof finishing. Products mainly by strong fibrous material strength and fabric density to decide.
