Abstract: In order to control the defects in the colored spun yarn, ensure the effect of fabric cover, and stabilize the fabric style, the production process of color spinning is optimized and improved. For example, a new cylinder clothing is selected for cotton carding while adopting flexible carding to reduce fiber damage. Drawing process is used to reduce the number of sliver doubling, reduce the total drafting multiple and drafting irregularity, stabilize the level of sliver and improve the fiber extended parallelization. In the spinning process, it is necessary to properly enlarge the roller spacing, increase the nip spacing block and reduce fine yarn defects. By adopting a series of process optimization measures, the defects of colored spun yarn are greatly reduced, the self-winding production efficiency is enhanced, the cloth quality is improved, and obvious results are obtained. The adoption of new carding equipment and process optimization measures has broken through the concept of "light weight and tight spacing" in traditional process, greatly reduced the defects in color spun yarn, and provided practical experience and innovative ideas for quality management and process research in color spun enterprises.

摘要： 为控制色纺纱纱疵,保证布面效果,稳定织物风格,对色纺纱的生产工艺进行优化和改进。例如梳棉精选新型锡林针布,采用柔性梳理,减少纤维损伤;并条工序减少并合根数、降低总牵伸倍数与牵伸不匀率、稳定条干水平,提升纤维伸直平行度;细纱工序适当放大罗拉隔距,增大钳口隔距块,减少细小纱疵。经过系列工艺优化措施,使色纺纱纱疵大幅降低,提高自络生产效率,改善布面质量,收到明显的效果。应用新型梳理器材和工艺优化措施,突破了传统工艺中“轻定量、紧隔距”的理念,可大大减少色纺纱纱疵,为色纺企业质量管理和工艺研究提供了实践经验和创新思路。
