Influence of spinning triangle shape change on ring spun yarn properties

In order to analyze the influence of spinning triangle shape change on ring spun yarn properties,based on diagonal spinning theory,a spinning triangle shape variation model was established.Conventional and diagonal spinning were conducted on different type ring frames to obtain the diagonal spinning triangle shape change,respectively. Yarn properties at various spinning triangles were compared and analyzed,and experimental verification is performed on the theoretical analysis results. Experimental results indicated that twisting effective transport and corresponding diagonal yarn guide mode could effectively reduce the area of the twisting triangle,improved the fiber holding effect of the triangle,and reduced resultant yarn hairiness,and the experimental results agreed with the theoretical analysis.
