织物透气阻抗对热湿移动的影响

本文应用模拟实验装置,就丝织物的透气阻抗对热湿移动特性的影响作了研究。结果表明,透气阻抗对织物热湿移动有较大的影响。其影响程度决定于透气阻抗 R 值,R>0.25 kPa·s/m 时,对干热散失无影响;对湿热散失有较小的影响,R<0.25 kPa·s/m 时,对热湿移动有明显的影响。

The Effects of Fabric Air Resistance on Heat and Wet Transfer

With simulative device,the effects of silk fabric air resistance on heat and wet vapour transfer in fabric are researched.The results show fabric air resistance considerably influences the heat and wet vapour tra- nsfer performance of fabric,and the degree of influence depends on its numerical value R.When R is greater than 0.25 kPa.s/m,the air resist- ance has a comparatively small influence on wet vapour transfer,but no influence on heat transfer;when R is smaller than 0.25 kPa.s/m,it obv- iously influences both.
