摘要
应用模拟装置,就风速和丝绸面料的透气性对热湿移动特性的影响进行了分析研究.结果表明,风速和透气性对热湿移动有明显影响,风速愈大,干、湿热散失愈多;透气阻抗R>0.25(kpa.s/m)时,透气性对干热散失几乎无影响,对湿热散失有一定的影响;R<0.25(kpa.s/m),对干热散失和湿热散失都有明显影响.实验结果还表明了真丝面料的湿热散失量明显地高于棉、毛、麻、涤纶和锦纶面料,热湿舒适性较好.
Using simulative devices, we made researches on the influence of air velocity and air penetra-
bility on heat wet vapout transfer. The results show that air velocity and air pentrability bave an
obvious influence on heat wet vapour transfer. The grecater the air velocity, the more the beat/wet
vapour loss when air resistance R>0. 25(kpa./sm). air penetrability bas Ittlc influence on wetloss.
Wben R<0. 25(kpa. s/m). air penetrability bas an obvionus infuence on beat/wet vapour transfer.
The results also show that the heat/wet vapour dissipation in silk fabrics is obuiously greater than
that in cotton, wool, ramie., ramie,, polyester and nylon fabrics, resukiting in a better heat/wet com
fort.
