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

摘要： 探讨色纺纱生产特性，分析胶辊、针布对色纺纱成纱质量的影响，通过对环锭纺细纱 胶辊、梳棉机针布选型试纺，根据成纱质量对比结果决定器材的选用。结果表明：聚氨酯胶辊具有极其优良的弹性， 较佳的耐磨性和抗粘附功能，满足色纺纱多品种、少批量、高品质的要求，能有效改善色纤维可纺性，提高成纱条干 水平；使用基厚较薄和双曲面锡林针布，可提高锡林表面的纤维从锡林到道夫间的转移能力，避免过度梳理和减少梳 理对纤维的损伤，有利于提高成纱强力和条干水平，横向齿密加大，可增强对纤维的分梳效果，降低成纱棉结、色结 ，特别是明显色结。
