摘　　要：为提升消防服面料整体的热防护性能,设计织造了2种智能改变厚度的隔热层(A1和A2试样),测试其增厚率,以及光辐射和热辐射状态下的热防护性能,并与常规消防服隔热层用芳纶非织造材料(B试样)进行比较。结果表明:在250~260℃的环境下烘5 min后,A1和A2试样的增厚率分别为4.67%和9.41%,B试样则无明显增厚;A1和A2试样在近红外波段的光辐射状态下,热防护性能优于B试样;低热辐射状态下,A1和A2试样的热防护性能优于B试样。To improve thermal protective performance of firefighters protective clothing,two kinds of thermal barriers with intelligent adjustment thickness(A1 and A2 samples)were designed and weaved to test their thickening rate and their thermal protective performance under light radiation and thermal radiation,and compared with the conventional firefighter s protective clothing,that was thermal barrier aramid nonwovens(B sample).The results showed that,after being baked at 250~260℃for 5 min,the thickening rates of A1 and A2 samples were 4.67%and 9.41%respectively,but the B sample did not thicken significantly.The light radiation protective performance of the A1 and A2 samples near the infrared band were better than that of the B sample.The thermal protective performance of the A1 and A2 samples were better than that of the B sample under low thermal radiation.
