Through statistical analysis, the models of yarn evenness were built. Moreover, the relationship between the evenness of spinning yarn and roving yarn was also investigated. The results showed that a positive correlation existed between them, and the mount of thin place per kilometer was the most important factor which could influence the evenness of woollen cashmere yam. The influence of the amount of neps and thick place on the yam evenness was indistinctive. The conclusions obtained would be helpful to improve the precontrol ability on yarn evenness.展开更多
