反热辐射层对消防服织物组合热防护和舒适性能的优化

Optimization of thermal protection and comfort of fabric combination with anti-thermal radiation layer for fireman clothing

为优化消防服织物的服用性能,在常规四层织物组合的基础上增加铝层反热辐射层,通过打孔改善铝层的透气性。测试五层组合的热防护性能(TPP值)和舒适性能(总热损失),利用密切值法探究反热辐射层对消防面料热防护和舒适性能的影响。结果表明:在不同位置增加反热辐射层后,组合织物的TPP值均有提高,且当反热辐射层位于外层与防水透气层之间时,热防护性能最好。随着反热辐射层孔洞率的增大,织物组合的TPP值变化不明显。当孔洞率由0个/cm^2增大到26个/cm^2时,织物组合的总热损失依次增大。当反热辐射层孔洞率为26个/cm^2时,织物的综合性能最好,优于四层织物组合。

In order to optimize the wearing performance of the fireman clothing fabric, anti-thermal radiation layer is introduced on the basis of common 4-layer fabric combi nation whose permeability is improved through punching. In order to optimize the wearability of fabric combination for fireman clothing, each combination's index of thermal protective performance(TPP) and comfortable performance are tested. The results show that with the anti-thermal radiation layer in different layer, TPP values of all combinations raise, and when the anti-thermal radiation layer is between the outer shell and the moisture barrier, the TPP value is the best. As the porosity of the anti-thermal radiation layer increases, the TPP value of the fabric combination does not change significantly. When the porosity per square centimetre of the anti-thermal radiation layer changes from 0 to 26, the thermal-moisture comfort of the fabric combination in creases in turn. When the porosity per square centimetre of the anti-thermal radiation layer is 26, the overall performance of the fabric combination is the best, which is superior to the 4-layer fabric combination.
