文摘This paper introduces the main characteristics of semi-worsted yam.By introducing the compact spinning technology,increased the fiber compact device in the semi-worsted spinning process,and basically eliminates the twisting triangle area.The strength,hairiness and evenness of the ordinary and the improved semi-worsted yams were tested.The result shows that the strength of the improved yams increase 10%,short hairiness reduce by 50%,and unevenness rate drops about 38%.
