Effect of spinning conditions on mechanical and performance characteristics of cotton ring- and compact-spun yarns

Abstract

The effect of spinning conditions on the structural, mechanical and low -stress response of cotton ring- and compactspun yarns has been studied. Spinning conditions include spinning draft, twist factor, yarn tex and spindle speed. Generally, the compact- spun yarns display higher mean migration intensity and lower values of mean fibre position, helix angle and helix diameter. It is also observed that the yarn structures produced under various spinning conditions yield different performance characteristics and the differences are quite meaningful; however, using appropriate twist factor and varying spindle speed, one can successfully spun yarns with less hairiness, better abrasion resistance, and quite sufficient structural integrity and compressional energy. An optimal spinning draft is required if the optimum level of structural integrity, compressional energy, compressional resilience and abrasion resistance of a yarn needs to be achieved for a specific enduse. The behaviour of compact-spun yarns is noticeably better in respect of tensile strength, work of rupture, abrasion resistance, hairiness and mass irregularity.
