摘　　要：为了解热防护织物吸湿状态下的防护性能,以提高织物的安全防护能力,首先,选取热防护织物组成多层组合S-1和S-2,利用热防护性能测试仪,分别测试织物组合S-1和S-2在外层织物不同含水率情况下的热防护性能（TPP）值及二级烧伤时间;然后,建立线性回归方程,描述在4种含水率下织物TPP的变化情况,分析外层织物的含水率对热防护服多层织物组合TPP的影响。结果表明：对于所有织物组合,二度烧伤时间和TPP值都随外层织物含水率的增加而明显增加;当外层织物的含水率增加到30%左右时,外层织物的含水率直接影响消防服整体的TPP,含水率越高,消防服的TPP越好。In order to determine the protective properties of thermal protective fabrics under humid conditions and improve the ability of fabric,firsly,the thermal protection fabrics were selected to form multi-layer combinations S-1 and S-2, the TPP and second-degree burn time of multi-layer fabrics combinations S-1 and S-2 were determined as a function of moisture of outer layers by using thermal protection performance test instruments. Then,a linear regression equation was established,and the changes in fabric thermal protection performance at four water cut rates were described. The effect of moisture of outer layer fabric on thermal protection performance of thermal protective clothing multilayer fabric was analyzed. The results show that for all the fabric combinations,there is appositive correction between the TPP or the second degree burn time and moisture of outer layers,that when the moisture of the outer fabric increases to about 30%,the moisture of the outer fabric directly affects the TPP of the whole fire fighting suit,and that the higher the moisture is,the better the TPP will be.
