摘　　要：采用原料先染色后再混合纺纱,可比先纺纱后染色的染色纤维量显著减少。但染色后纤维的性能有较大变化,棉纤维强力下降,短绒增加,弹性变差,影响纺纱的可纺性,故要根据染色后纤维性能的变化来设计纺纱工艺。文章根据浙江地区相关企业多年来生产色纺纱的实践,分析了色纺纱的纺纱生产工艺特点与本色纱工艺的不同点,对色纺纱主要工序的工艺设计要点作了分析与叙述。Since the raw material is first dyed and then mixed spinning is carried out,the quantity of dyed fibers can decrease significantly,compared with first spinning and then dyeing.But,fiber properties change a lot after dyeing.The strength of cotton fiber decreases;short fibers increase,and the elasticity declines.The spinnability is influenced.Thus,spinning technology should be designed according to fiber property change after dyeing.Based on colored spun yarn production practice of relevant enterprises in Zhejiang,the differences of production technology between colored spun yarn and naturally colored yarn were analyzed.Meanwhile,key process design points of main procedure of colored spun yarn were analyzed and stated in this paper.
