摘　　要：本文旨在探讨将聚(苯乙烯-乙烯-丁烯-苯乙烯)(SEBS)作为防水透气膜与不同规格针织、机织面料复合后的性能特点。通过扫描电子显微镜、红外光谱仪、接触角测定仪、全自动透气量仪、电脑式织物透湿仪、电子织物强力机对该种防水透气膜和不同种复合织物的微观结构、化学组成、接触角、透气量、透湿率、拉伸性能进行表征。结果表明,与SEBS膜相比,复合织物的透气率提升了29.4%~935.1%,透湿率提升了3.8%~260.0%。复合织物均具有疏水性。复合织物与未进行膜复合的面料相比,拉伸强度增加了6.4%~22.4%,断裂伸长率提升了2.2%~23.0%。与市面上应用的聚氨酯复合织物相比,SEBS复合织物具有优良的疏水性和透气性。SEBS复合织物相较于未复合的面料更加耐用,具有更出色的柔韧性和弹性,在透气性和防水性方面具有一定优势,是户外服装和用品的理想选择。This article aimed to investigate the performances of poly(styrene ethylene butene styrene)(SEBS)as a waterproof and breathable membrane combined with some knitted and woven fabrics of different specifications.By the scanning electron microscope,infrared spectrometer,contact angle meter,automatic air permeability tester,computer-based fabric moisture permeability tester and electronic fabric strength tester,the microstructures,chemical compositions,contact angles,air permeability,moisture permeability and tensile properties of the waterproof and breathable membrane,and various composite fabrics were characterized.The results show that,compared with SEBS membranes,the air permeability of the composite fabrics increases from 29.4%to 935.1%,and the moisture permeability of the composite fabrics improves from 3.8%to 260.0%.All composite fabrics have hydrophobic properties.Compared with the non-laminated fabrics,the breaking strength of the composite fabrics increases from 6.4%to 22.4%,and the elongation at break improves from 2.2%to 23.0%.Compared with the polyurethane composite fabrics on the market,the SEBS composite fabrics have good hydrophobicity and air permeability.SEBS composite fabrics are more durable than non-laminated fabrics,have better flexibility and elasticity,and have certain advantages in air permeability and water resistance,making them ideal for outdoor clothing and supplies.
