聚四氟乙烯膜面料的开发及其关键性能测试

Development of polytetrafluoroethylene membrane fabric and its key performance testing

阐述了聚四氟乙烯膜的制备原理、性能,并讨论了聚四氟乙烯膜面料性能的影响因素。对开发的男装夹克面料的透气率、沾水等级、透湿率等性能进行测试。结果表明,该面料的透气率达到186 mm/s,沾水等级4~5级,透湿率7.71×10^(3)g/[m^(2)·(24 h)],各方面性能达到功能纺织品的要求。

The preparation principle and properties of polytetrafluoroethylene membrane were expounded,and the influencing factors of the properties of polytetrafluoroethylene membrane fabric were discussed.The air permeability,spray rating and moisture permeability of the developed men's jacket fabric were tested.Results showed that the air permeability was 186 mm/s,spray rating level was 4~5,and the watervapour transmission rate was 7.71×10^(3)g/[m^(2)·(24h)].All the properties could meet the requirements of functional textiles.
