纱线捻度的知识gydF4y2Ba

纱:纱和线程的通用术语。有很强的条幅,包括单纱和股。单纱:由短纤维处理,使短纤维或电线沿着轴向方向和扭曲。合股纱:它是由两个或两个以上的单纱和扭曲。其强度和耐磨性优于单纱。同时,合股纱也可以组合和扭曲以某种方式获得复合捻合股纱。捻线是什么?如果带的一端,另一端转动时,纱线就可以形成,称为扭曲。短纤维,扭曲的必要手段是使纤维纱条。通常需要浓缩的纤维成纤维带扭转之前,和外层纤维的纤维被挤压到内层。 Thereby, the strip is obtained in the longitudinal direction of the fibers. For long silk yarns and strands, twisted can form a tight structure that is not easily damaged by lateral force, and twisting can also form a variant wire and a fancy line. How many of the twisted and twisted direction not only affect the hand feel and appearance of the fabric, but also affect the intrinsic quality of the fabric. After the strip is twisted, the outer fibers produce a tilted helical roll back, the fiber torsional deformation, the gauze is tightly bored, and the structural form and mechanical physical properties of the fiber collective are changed. (As shown below) When there is an encirclement angle, the fiber has centripetal pressure on the yarn. The greater the encirclement angle, the greater the centripetal pressure. Due to the existence of centripetal pressure, the outer fiber is extruded to the inner layer, which increases the compactness of the yarn and the friction between the fibers, thus changing the structural form and physical and mechanical properties of the yarn, which is th
