ABSTRACT

An energy-efficient method that improved spun-yarn properties was previously reported, however, the improvements differed as the varying contact-shaped strands passed through the static rod and self-adjustable disk contact surfaces. Thus, models of three strand-contacting shapes were built: straight, convexing-up, and concaving-down. Then, the influence of the strand-contact shapes on the spun-yarn properties was theoretically analyzed, while spinning with a static rod and self-adjustable disk contact surfaces. The conducted experiments disclosed that the yarn hairiness was significantly reduced for all three models of the strand-contact shapes, with rod and disk surfaces in the yarn-formation zone. The spun-yarn tenacity was slightly enhanced only for the strands passing through the convexing-up and concaving-down contact shapes. The experimental results were consistent with the theoretical analysis.

摘要

先前报道了一种提高纺纱性能的节能方法，但是，随着不同接触形状的股线穿过静态杆和自调节盘接触表面，这些改进有所不同。因此，建立了三种链接触形状的模型：直的、上凸的和下凹的。然后，从理论上分析了股线接触形状对纺纱性能的影响，同时采用静态杆和自调节盘接触面进行纺纱。所进行的实验表明，纱线接触形状的所有三种模型的纱线毛羽均显着降低，在纱线形成区具有棒状和盘状表面。只有通过上凸和下凹接触形状的股线，纺纱强度略有提高。
