摘要
研究了消防服用多层织物系统的阻燃性能及其TPP值。将耐高温阻燃的Nomex、Kermel和芳砜纶织物与PTFE、TPU和三维阻燃间隔织物组合,模拟消防服的层次构成,通过垂直燃烧试验测试分析外层织物的阻燃性能,通过TPP试验测试分析多层织物系统的综合热防护性能。研究得出:热防护性最好的织物组合是芳砜纶、三维阻燃间隔织物和阻燃棉布,其综合热防护性能TPP值为51.9;最适宜用于消防服的织物组合是NomexⅢA、三维阻燃间隔织物和阻燃棉布,其综合热防护性能TPP值达到50.7;将三维阻燃间隔织物用于消防服结构组成,可取得较好的整体热防护效果且可减轻消防员热负荷。
The integrated thermal protective performance of the multi-fabric system used for fire-fighting suits is researched in this article.Multi-fabric systems were composed by simulating the fire-fighting suits with fabrics including Nomex,Kermel,PSA,PTFE,TPU and three-dimensional spacing flame-retardant fabric.Outer fabric′s flame-retardant performance is tested by vertical flammability test,the integrated thermal protective performance of the multi-fabric systems is tested by TPP test.The experiments reveal that the best thermal protective performance fabric system consists of PSA,three-dimensional spacing flame-retardant fabric and flame-retardant cotton fabric,which TPP value is 51.9;the most appropriate fabric system for the fire-fighting suit consists of NomexⅢA fabric,three-dimensional spacing flame-retardant fabric and flame-retardant cotton fabric,which TPP value is 50.7;three-dimensional spacing flame-retardant fabric can be used in fire-fighting suit structure and will achieve better overall protective effect and reduce firemen′s thermal load.
