Popis: | 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. |
