摘　　要：选用共聚酰胺(COPA)热熔胶为黏合剂,采用平板硫化机将面料、热熔胶、聚四氟乙烯(PTFE)薄膜、热熔胶、里料5层结构热压制成防水透湿层压织物。层压工艺采用正交试验设计,进行4因素3水平共9种层压工艺的正交试验。对9种工艺条件下制得的层压织物进行透湿性能、剥离强度、耐静水压以及透气性能的测试,最后采用灰色近优理论处理数据,得出最优工艺为:面料与薄膜间的上胶量为12 g/m^2,里料与薄膜间的上胶量为24 g/m^2,层压温度为140℃,层压时间为10 s。Copolyamide （COPA） hot melt adhesive is selected as a binder, five lays of surface fabric, hot melt adhesive, PTFE film, hot melt adhesive and linning fabric are laminated together by hot pressing with plate vulcanizing machine. Laminating process is optimized by orthogonal experimental design with a four factors three levels. Testing is carried out on the obtained laminated fabrics with nine processes for moisture permeability, peel strength, hydrostatic pressure resistance and gas permeability. The optimum process is determined by grey near optimal theory as： coating amount of 12g/m2 between fabric and film and of 24g/m2 between linning fabric and film, and laminating at 140℃ for 10s.
