几种环保纤维混纺纱的芯吸与吸放湿性能

本文对柔丝、蛹蛋白、天丝、彩棉等绿色纤维混纺纱进行芯吸性能和吸放湿过程测试，并利用Origin软件对测试结果进行对比，分析研究不同纱线的吸湿性及湿传递性能，以期找出影响纱线吸放湿性能的较为普遍性的规律，并为开发湿舒适性好的绿色服装面料提供依据。结果表明：含再生纤维的混纺纱的芯吸性能较强，尤其含有皮芯结构的蛹蛋白再生纤维的纱线芯吸性能最好，含有50%以上的柔丝纤维的纱线吸放湿能力最强，其回潮率和吸放湿速率都较高。天然棉/彩棉混纺纱的芯吸性很差，并且其回潮率及吸放湿速率都较低。

Capillary effect and moisture absorption and liberation property of yarns blended with some environment friendly fibers

The capillary effect , moisture absorption and liberation property of yarns blended with new green fibers such as pupa protein fiber, Rousi fibers,Tencel fiber, color cotton were studied in this paper. Their liquid wicking height and moisture absorption and libertation process were tested. The tested data were contrasted by using Origin software in order to find the more universal laws which have relation with the moisture absorption and liquid transfer property of yarns, and the tested results could provide evidence for developing green fabrics with good wet comfort. The results show that the yarns that blended with regenerated fibers have good capillary effect, especially the yarns blended with pupa protein fibers which are of skin-core strcture. The yarn blended 50% Rousi fibers has the best moisture absorption and liberation property. Its moisture regain and rate of absorption and liberation are all higher. The capillary effect of cotton/color cotton yarns are very poor and these two yarn have lower moisture regain and absorption and liberation rate.
