【摘要】 研究了可重复用医用防护织物的防护效果，结果表明：加入聚四氟乙烯膜可以使织物的抗渗水性能静水压大于38kPa，抗合成血液穿透性大于4级，过滤效率大于90%，透湿率降低至5 900～10 000 g/（m~2·24 h）；重复洗涤可能造成聚四氟乙烯膜内微孔堵塞甚至裂开；经过20次重复洗涤后聚四氟乙烯防护织物抗渗水性能下降，透湿率升高，表面抗湿性能下降，抗合成血液穿透性与过滤效率变化不明显。更多还原

【Abstract】 The prevention effect of the reusable medical protective fabric was studied.To the fabric with PTFE film, it showed that the fabric with PTFE film could improve the prevention of the water seepage index up to 38 kPa, improve the prevention of artificial blood seepage index up to level 4, improve the filtration efficiency index up to 90%, and improve the moisture permeability index to 5 900～10 000 g/(m~2 · 24 h). Repeat lauder would make the tiny holes in the PTFE film clogged or even torn slightly. After 20 times of repeated lauder, the prevention of the water seepage of fabric with PTFE would decline, the moisture permeability would increase, the prevention of artificial blood seepage and the filtration efficiency remained the same.更多还原
