Study on the Properties of Cotton Yarn with Modified Yarn Path in Ring Spinning

Abstract

Spinning triangle is a critical area that influences the physical and mechanical properties of yarn. Previous researchers have done several works related to spinning triangle by modifying yarn path primarily considering only one side diagonal yarn path meaning that either left or right diagonal yarn path. The others used single yarn count and twist level on different variety of raw materials. This research was produced cotton ring yarns by varying count (36 Ne, 40 Ne) and twist level (1014 TPM, 1080 TPM) using right and left diagonal paths in Z-twist direction. The yarns were tested and it was observed that 25%, 0.34%, 37% and 25% reduction in hairiness, CVm%, thin place and thick place respectively with slight decreasing of tenacity in left diagonal path yarn. In right diagonal path yarn there is 3%, 16%, 59% and 14% increasing of yarn hairiness, CVm%, thin place and thick place respectively with 10% reduction of tenacity. Therefore, the left diagonal path has a significant improvement of ring spun yarn quality in terms of physical properties. On the other hand, the right diagonal path yarn were deteriorated all the physical and tensile properties of ring spun yarn. This is occurring due to the mismatching of right diagonal path with Z-twist direction.
