摘要
防水透湿膜是一种具有防水和透湿双重功能的高分子薄膜材料,与纺织面料经层压复合后可制备出兼具耐水渗透性和水蒸气透过性的功能性织物。目前,按照防水透湿原理或阻止液态水渗透和水蒸气传输的机理,防水透湿膜可分为微孔型、无孔型、双组分型3种。文章对这3种防水透湿膜的特点、作用机理进行了总结,并归纳了其性能评价方法以及在纺织领域的应用现状,同时对其发展趋势进行了展望。
Waterproof and moisture-permeable membranes are polymer film materials with dual functions of waterproof and moisture permeability.Functional textiles with water permeability resistance and water vapor permeability can be prepared by laminating fabrics with such membranes.So far,according to the principle of waterproofing and moisture permeability or the mechanism of preventing liquid water penetration and water vapor transmission,waterproof and moisture-permeable membranes can be divided into three types,i.e.,microporous ones,non-porous ones and two-component ones.This paper summarizes the characteristics and mechanisms of these three types of membranes,concluded related performance evaluation methods and applications in the textile field,and looks forward to the development trend.
