摘要： 为增强防护服用聚四氟乙烯(PTFE)复合膜的防护性和弹性,提出了PTFE与热塑性聚氨酯(TPU)共同拉伸制备PTFE/TPU复合膜的方法。这种方法还避免了PU涂层PTFE制备复合膜中PU溶剂污染环境等不足。采用扫描电镜、万能强力仪和透湿试验装置分别测试了共同拉伸和涂层复合膜的结构、弹性和透湿性。结果表明,与涂层复合膜相比,共同拉伸复合膜中的聚氨酯膜上完全没有微孔,这增强了薄膜制品的防护性和弹性;共同拉伸膜的透湿量也达到服装舒适性要求。

Abstract: For improving the protective and stretch recovery properties of micro porous polytetrafluorethylene(PTFE) membrane,a co-stretching of PTFE and thermoplastic polyurethane(TPU) process was proposed,which avoided the problem of environmental pollution from the solvent.The structure,percentage stretch recovery and water vapor transmission quantity of the co-stretched PTFE/TPU layered membrane and PU coated PTFE layered membrane were tested respectively using electron microscope,universal materials testing machine,and the water vapor transmission rate-dish.The test results show that compared with PU coated membrane,the co-stretched membrane has no micropores on its surface,which enhances its protective and stretch recovery properties,while keeping moisture permeable for comfortable wear.
