聚四氟乙烯薄膜复合蒸呢包布及其应用性能

为了提高羊毛精纺面料的表面光泽及其耐久性，采用聚四氟乙烯（PTFE）微孔薄膜与传统包布复合研制新型复合蒸呢包布，测试采用新型复合包布罐蒸后毛织物的各项性能。结果表明；PTFE微孔薄膜的结构对复合包布的透湿量影响较小；采用复合包布经一次罐蒸的毛织物，其表面平整性、尺寸稳定性、力学性能、表面光泽都优于采用传统包布一次罐蒸的毛织物；采用复合包布经两次罐蒸的毛织物的表面平整性、尺寸稳定性、力学性能、表面光泽基本达到传统包布经罐蒸→电压→罐蒸的织物的效果。

PTFE Membranes Laminated Decatizing Wrapper and Its Application Performance

In order to improve the luster and its durability of worsted fabrics, polytetrafluoroethylene （PTFE） microporous membrane and conventional decatizing wrapper are laminated to develop a new composite decatizing wrapper. The properties of the finished fabrics are measured and analyzed. The results show that, the structure of PTFE microporous membrane has less impact on moisture permeability of the new wrapper Compared with conventional wrapper fabrics, the new PTFE membrane laminated wrapper behaves better in surface smoothness and evenness, size stability, mechanical properties and luster for worsted fabrics processed by kier decatizing; The worsted fabrics finished by decatizing twice with the new wrapper can reach the same result with the worsted fabrics finished by decatizing→paper pressing→decatizing with the traditional wrapper.
