Abstract: This paper discusses production characteristics of colored spun yarn, analyzes the influence of rubber covered roller and card clothing on the quality of colored spun yarn and determines the selection and use of accessories according to spinning quality comparison result through trial spinning with rubber covered roller of ring spun yarn and card clothing of carding machine. The result shows that polyurethane rubber covered roller has excellent elasticity and good abrasive resistance and anti-adherence function, meets requirements of multispecies, small batch and high quality of colored spun yarn and can effectively improve the spinnability of color fiber and evenness of yarn; the use of cylinder card clothing with thin base and double curved surfaces can improve the transfer ability of fiber on cylinder from cylinder to doffer, avoid fiber damage caused by excessive carding and carding reduction, improve the strength and evenness of yarn, increase lateral teeth density, reinforce carding effect for fiber and reduce cotton neps and color neps, especially obvious neps.

Key words: colored spun yarn, spinning accessories, rubber covered roller, card clothing, evenness, nep
