【摘要】：以高密异收缩涤纶复合丝织物、3M气溶胶和聚四氟乙烯(PTFE)微孔膜为基材,通过层压来制备防水透湿层压复合织物,并对复合织物的剥离强力等性能进行测试,探索出复合织物的最优工艺。实验结果表明,不同的层压工艺对层压织物的剥离强力产生很大的影响,特别是上胶量。随着上胶量的增大,层压织物的剥离强力而增大,但增大到一定程度时不能完全剥离;而透湿性、柔软性变得较差;当热压温度为100℃,热压压力为0.3MPa,上胶量为31.8g/m~2时,防水透湿层压复合织物的性能较优,透湿量为5010g/(m~2·24h),弯曲刚度(B)达到0.2833N/(m~2·cm),滞后矩(2HB)达到0.1132N·cm/cm。
[Abstract]:The waterproof and permeable laminated fabric was prepared by laminating 3M aerosol and polytetrafluoroethylene (PTFE) microporous membrane, and the properties of the composite fabric were tested by laminating, and the optimum technology of the composite fabric was explored. The results showed that the laminating fabric was stripped by different laminating processes. It has a great influence on the strength, especially the amount of glue. With the increase of the amount of adhesive, the peel strength of the laminated fabric increases, but it can not be completely stripped to a certain extent; and the moisture permeability and softness become worse. When the hot pressing temperature is 100, the hot pressure is 0.3MPa and the sizing is 31.8g/m~2, the waterproof and permeable laminating composite fabric is made. The performance is excellent, the moisture content is 5010g/ (m~2. 24h), the bending stiffness (B) reaches 0.2833N/ (m~2 cm), and the hysteresis moment (2HB) reaches 0.1132N. Cm/cm..
