减少纱线质量变异的评析

Evaluation on the reduction of yarn quality differentiation

提出了总体质量的理念,认为纱线质量应包括质量平均值和质量变异系数两方面,论述了总体质量与质量变异系数的关系,强调减小质量变异系数必须从技术、管理两层面着手,实现综合管理和精细管理。评析了纱线细度、条干、强度、直径、毛羽、捻度质量变异对产品质量的影响,认为当前要特别注意控制纱线条干、强度、毛羽变异系数,并提出了相关措施。

A general concept of yam quality is put forward in this paper, which holds that the yarn quality should be made of the yarn quality average value and the yarn quality differential co -efficient. The relafion between the yarn general quality and yam quality differential co -efficient is commented with focus on it that the reduction of yarn quality differential co -efficient has to be made from both technic and management, and the realization of complex management and fine management. The effect of yam fineness, irreguolation, strength, diameter, hairiness and twist on yarn quality differential co-efficient is evaluated with special attentions on the controlling of yarn irzegulion, strength and hairincss.
