摘　　要：以毛细效应和湿蒸发原理为基础 ,对不同截面形状和加工方式的涤纶长丝在不同捻度条件下芯吸高度的变化规律进行了实验研究。结果表明 :特殊异形截面涤纶长丝较圆形截面的芯吸效果好 ,加弹丝的芯吸效果好于平牵丝 。The wicking capability of yarns affects wettability and transmissibility of fabr ics.Based on the capillary effect and evaporation principle,the effects of cross -section,processing methods and twist on wicking height are studied experimental ly in this article.Finally,the results show that the wicking capability of profi led filament is better than that of filaments with circular cross-section,the wi cking capability of low-elastic yarn is better than that of the parallel-draft y arn and the effects of twist on wicking capability of polyester filament yarns d isplay trends as Lorentzian curve.
