摘　　要：详细介绍了机采棉的特性,以纺CJ 14.6tex、集聚纺CJ 9.7tex纱为例,制定纺纱工艺流程;清梳联采取"柔性渐进梳理、充分排杂、降低棉结"的工艺路线,优化各梳理参数,对双齿型针布和单齿型针布的成纱条干均匀度、粗细节及棉结进行对比分析。指出:机采棉较手采棉物理品质下降,纺纱时棉结多、强力低、毛羽多,必须进行工艺优化和器材优选以减少成纱质量波动;双齿型针布条干指标较单齿型针布有较大幅度的改善;双齿型针布梳理度增加,有利于开松除杂、减少落棉量,提高生产效率。As to the Xinjiang machine-picked cotton regarding low grade,high content of foreign fibers,neps,and short sluhs,sampling spinning of CJ 14.6 tex,CJ 9.7 rex compact spun yarn, process flow is figured out and the blow-card combination is programmed as＂flexible and pro- gressive carding, full impurities removing, and neps reduction＂. Carding parameters are optimized.Comparative analysis is done to double-teeth wired clothing and single-tooth wired clothing regarding yarn evenness,slubs and neps.It concludes that machine-picked cotton is inferior to the hand-picked cotton in physical performance.Something must be done to optimize processes and accessories selection against yarn quality fluctuation.The double-teeth wired clothing is much better than the single-tooth wired clothing in improving eveness.And increase of carding degree of the former helps opening and removing of impurities with less waste and higher production.
