利用贴合技术开发多功能军用雨衣面料

Development of multifunctional military raincoat fabric using fitting technique

开发了高透湿高防水军用雨衣面料，以林地迷彩牛津面料为基布，先对基布进行压光处理，然后采用高透湿性聚氨酯和各类助剂作为面胶和底胶，利用转移贴合技术，在织物上复合一层很薄的高分子亲水性聚合物Pu膜，剥离后再对其进行拨水整理，主要赋予面料防风、防水及高透湿的性能。经测试，该面料性能指标为：洗涤后的外观保持性为4．0级：静水压为14760mmH，0，20次洗涤后为5671mmH20；表面拒水性4-5级，20次洗涤后4-5级；透湿率3990g／（m2．24h）；静电电荷密度2．8uc／m2；湿热空气加速老化等级4-5级。由测试结果可知，所设计的功能面料符合相关标准的技术要求，可满足客户的使用需求。

Use Woodland camouflage paint Oxford fabric as the base cloth, the calendaring is carried out on the fabric, and then compounded with a thin macromolecule hydrophilic polymer PU film by transfer laminating technology with high water vapor permeability polyurethane and various additives as surface glue and bottom glue, followed by a waterproof finish after stripping to impart the fabric with high performance of the windproof, waterproof and moisture permeability. Testing results show that the performance index of the fabric are： the smoothness appearance of fabrics after cleaning is above grade 4.0; hydrostatic pressure is 14 760mm H20 and 5 671mm H20 respectively before and after 20 times launderings ; surface water repellency level keeps 4 -5 grade before and after 20 times launderings ; water vapor permeability is 3 990g/（m2 - 24h） ;electrostatic charge density is 2.8uc/m2 ;humid air accelerated aging grade is 4-5 grade. The designed functional fabric can meet the technology requirement of the standards, and also the demand of the customers＇.
