Research on the performance of waterproof and moisture permeable PU film laminated fabrics
Abstract:With polyester fabric,hot melt rubber TPU and PU film of high moisture permeable as basic material, the waterproof and moisture posite fabric was prepared by posite method. The tensile,pendant,air permeable,waterproof and moisture permeable performance of polyester fabric, PU film posite fabric were tested. The effect of different amount of posite temperature posite pressure on the performance posite fabric were discussed. The results showed that the tensile strength posite fabric was improved at certain degree after the polyester and PU film posited,but the pendant performance of posite fabric was worse than that of polyester fabric,the waterproof effect posite fabric was better than that of polyester fabric obviously,while the air and moisture permeable performance of posite fabric were worse than that of PU film. When the amount of TPU with 22 g/posite pressure of 5 posite temperature of 80 °C,posite effect of posite fabric is the best.
Along with the rapid development of science and technology, especially the advanced science and technology development, sex for spinning weaving product can carry out more to the higher, more to the more appearance and development of waterproof and moisture permeable fabric is the result of modern science and technology progr
