作者简介：温瑞杰(1991—)，女，河南开封人，助理工程师，主要从事棉纺工艺方面的工作。 Abstract:In order to improve the spinning quality，the cause of the worst CV_b value of yarn is analyzed；it is expounded the measures that to reduce the weight unevenness of half products，strength unevenness and twist unevenness. It is pointed out that we should focus on controlling the weight deviation of card sliver and drawing.Reducing the difference between large and medium roving elongation and the difference between front and back row sliver tension to reduce the uneven weight of roving.In the spinning process，the same type machine should be adopted for the same yarn variety，efforts to find defects should be strengthened and stable drafting should be ensured.We should pay attention to the influence of yarn strength weakness and twist unevenness on CV_b value.
Key Words: CV_b ；weight unevenness；difference in elongation； difference in tension；strength weakness；soft twist
