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.
