摘要
消防员灭火防护服多为外层、防水透气层、舒适层 3 层织物制作,3 层组合试样的质量和防护服质量直接相关.为了增强 3 层组合试样的热防护性能,实现灭火防护服轻量化,提高灭火救援的效率,试织了芳纶双层织物和玄武岩/阻燃粘胶包覆织物,试制了芳纶双层包覆聚四氟乙烯(PTFE)膜织物.选择 2 种舒适层织物和 1 种轻量防水透气层材料,制成不同组合试样并进行热防护性能测试.试验结果表明:3 层组合试样经热防护性能测试后,玄武岩/阻燃粘胶包覆织物组织基本完整,防水透气层的PTFE膜炭化、损毁,防水性能缺失;芳纶双层织物做外层,芳纶混纺凹凸织物为舒适层的组合试样TPP值达 1 495.2 kW·s/m2,试样厚度大于 3 mm.
Abstract
Fire-fighting protective clothing is mostly made of outer layer,waterproof breathable layer and comfort layer,and the weight of the combined sample of 3 layers is directly related to the weight of the protective clothing.In order to enhance the thermal protection performance of the 3-layer composite sample,achieve lightweight fire-fighting protective clothing and improve the efficiency of fire-fighting and rescue,the aramid double-layer fabric and the basalt/flame retardant viscose coated fabric were woven,and the aramid double-layer+PTFE membrane fabric was prepared.Two kinds of comfort layer fabric and one kind of lightweight waterproof breathable layer material were selected to make different combination samples and the thermal protection performance were tested.The test results show that the basalt/flame retardant adhesive coated fabric structure is basically complete after the thermal protection performance test of the 3-layer composite sample,and the PTFE film of the waterproof breathable layer is charred and damaged,and the waterproof performance is lost.The TPP value of the combined sample with an aramid double-layer fabric as the outer layer and an aramid blend concave-convex fabric as the comfort layer is 1 495.2 kW·s/m2,the sample thickness is greater than 3 mm.
