低温环境下多层衣着的湿传递特征的研究

环境温度对织物的热湿传递影响是显著的，采用自行研制的低温下织物热湿传递特性试验装王，采用Coolmax涤纶针织物和纯棉针织物作内衣层试样，Thermolite Barrier作中间保暖层试样，涤纶花瑶PrFE层合防水透湿织物和涤纶春亚纺PU涂层织物作外衣层试样，在-20℃的低温环境下测试并研究多层衣着的湿传递特征，并推导了多层衣着的总平均湿阻与各层织物的平均湿阻之间的关系。实验结果显示，在-20℃低温环境下的热湿传递过程中易产生凝结，凝结多发生在内衣层和中间保暖层，透湿性好的外衣层和吸湿好的内衣层的总平均湿阻值小，导湿性能好的内衣层上凝结水量少。

Finishing Effect on Warmth Property of Cotton/Kapok Blended Knitted Fabric

Nowadays,more and more natural or functional fibers are being investigated due to their utilization in thermal underwear.Kapok fiber is one of the natural cellulosic fibers whose source is the kapok plant. It has hollow body and sealed tail,which exhibits desirable features required for functional textiles of this nature. In this study,cotton / kapok( 80 /20 by mass) blended yarn with two types of yarn size 18. 5 and 14. 8 tex,respectively are knitted into plain stitches. The fabrics are undergone with an optimal preparation plan according to orthogonal design. Then,after dyeing and softening,fabric properties including thermal and water-vapour resistances, wicking property, pilling behaviour, and surface morphology,are tested and scrutinized for their candidacy for thermal underwear. The results showed that cotton / kapok blended fabrics have good thermal resistance which is significantly higher than those of cotton / modal blended fabrics,and the same water vapour resistance compared with cotton / modal blended fabrics which are normally used as underwear. Cotton / modal blended knitted fabrics has better pilling grade than cotton / kapok blended fabrics. Meanwhile, the cotton / kapok blends fabrics have good wicking property. Collectively,it was concluded that cotton / kapok blended fabric was appropriate for thermal underwear. However,the main limitation of these fabrics is their pilling properties.
