摘要
采用YG 601型织物透湿仪和被动式微气候仪,在3种标准试验条件和4种微气候仪条件下,对3种6块Gore-Tex试样和2块棉织物试样进行了透湿性能测试。在标准透湿杯条件下,各试样的透湿量差异相对较大,平均透湿量与透湿量差异与试样两侧所存在的蒸汽压差成正比,Gore-Tex试样平均透湿能力要小于普通棉织物。采用被动式微气候仪的透湿试验发现:试样的透湿量与模拟皮肤内的水温成正比,水温越高,皮肤出汗量越大,内外湿度差越大,试样的透湿量也越大,同时微气候室内的积水也越多;在稳态情况下,微气候室内的积水量随时间成正比;在相同条件下Gore-Tex试样及棉织物试样的透湿量相差很小,但前者在微气候室内的积水量要大一些,也说明不同Gore-Tex织物的透湿量接近但还是小于普通棉织物。虽然Gore-Tex织物的透湿量接近棉织物,但其透气性能要远低于普通织物。所以,Gore-Tex织物称作防风透湿织物是准确的,其主要性能取决于PTFE(聚四氟乙烯)微孔膜的性能。
Using YG60 l fabric moisture permeability apparatus and passive micro-climate apparatus,an experiment is designed to test moisture permeability for three kinds six pieces Gore-Tex specimen and two pieces of cotton specimen for comparing in three kinds of standard test conditions and four kinds of artificial micro-climate conditions.In standard conditions of dish method,differences are very apparent in moisture permeability among all samples where the average moisture transmissions and variations of the value are proportional to the pressure difference of vapor on sides the specimen while the average moisture permeability of Gore-Tex specimen is little less than cotton specimen.Based on the results of fabrics moisture permeability experiment with passive micro-climate apparatus,the moisture transmission is directly proportional to the water temperature under simulated skin.The higher the water temperature is,the larger the sweating rate by skin is,the bigger the moisture differences on sides the specimen and the more the moisture transmission is while the more the water accumulation is in micro-climate room.The accumulated water is proportional to time under steady state conditions.The differences of moisture transmission between Gore-Tex fabric and cotton fabric are negligible in the same conditions,but more accumulated water with Gore-Tex fabrics shows that the moisture transmission of Gore-Tex fabric is closeto cotton fabric but less than it.The air permeability of Gore-Tex fabric is so far below cotton fabric comparing to moisture permission difference.Therefore,it is accurate for Gore-Tex fabric to call windproof and moisture permeability fabric which is mainly determined by property of micro-porous membrane of PTFE（polytetrafluoroethylene）.
