摘要: 通过实验对由导湿纤维纺成纱线的毛细管当量半径进行了计算。利用纱线毛细管当量半径并结合其它参数,对毛细效应高度进行理论预测,从而实现了理论预测该种导湿纤维及纱线的导湿性能。利用切片法对5种纱线的切片进行拍照,得到纱线的横截面照片,从横截面中选取典型区域,并对典型区域的总面积、典型区域中纤维所占面积进行计算,利用两面积之差,得到典型区域中毛细管的总面积。统计典型区域中毛细管个数,参照圆面积公式得到纱线中毛细管当量半径。结果表明,5种纱线中负氧离子涤纶长丝的毛细管当量半径最大,Coolmax纱线的毛细管当量半径最小。

Abstract: The article discusses the calculation method of the capillary equivalent radius of yarn made of moisture transmitting fibers through experiment.Using the capillary equivalent radius of yarn and other parameters,the wicking height can be theoretically forecasted,thereby the moisture transmitting property of fiber and yarn can be theoretically forecasted.The author slices five kinds of yarn and takes photos,and selects typical area from the cross section of the yarns,then the total area and the area of fibers in the typical area can be calculated.According to the above two areas,the area of capillaries is just the difference between the total area and the area of fibers.The number of the capillary can be gained via statistics.According to the area of capillaries,the number of capillary and the formula of circle,the equivalent radius of the five kinds of the yarns was gotten.The experiment result shows that among the five kinds of yarns,the equivalent radius of negative oxygen ion terylene filament is the longest,while the equivalent radius of Coolmax yarn is the shortest.
