摘要
采用垂直燃烧试验仪和火焰防护性能评价试验机，对消防服外层用织物进行阻燃及热防护性能测试，研究了热流密度和微小空气层厚度对阻燃织物热防护性能的影响。结果表明，随着热流密度的减小，织物热防护性能增加，质量损失率减小；在热流密度为80（1±5％）kW／m2，空气层厚度小于9mm的条件下，织物热防护性能随着空气层厚度增加而增加，空气层厚度为9—10nm时，织物热防护性能降低，大于10mm时，热防护性能随着空气层厚度增加而提高。
The flame resistance and thermal protective performance of outer layer fabrics in fire retardant clothing are investigated by vertical combustion test instrument and fire protection performance evalua- tion testing machine. The effects of flame heat flux and micro air layer thickness on thermal protective performance of flame retardant fabrics are studied. The result shows that with the decrease in the flame heat flux, the thermal protective performance is improved, Under the flame heat flux of 80×（1 ＋ 5%） kW/m2, the fire protection performance is improved with the increase in air layer thickness when the thickness is less than 9 nm or more than tO nm, and is decreased with the thickness of 9-10 mm,
