摘　　要：探讨改善纯棉普梳段彩纱条干质量的技术措施。针对当前段彩纱纱线条干水平普遍较差的问题,在原料选配和各生产工序采取了一系列工艺优化和管理措施,明显改善了段彩纱的条干水平,条干CV值降低2个百分点以上,千米粗节、细节降低50%、千米棉结降低40%。认为,通过合理配棉,提高染色棉质量以及对主粗纱原料进行混和预处理,优化各工序关键工艺,可以较好地达到改善纯棉普梳段彩纱条干水平的目的。Technology measures of improving of pure cotton carded segment-color yarn evenness level were discussed. A series of technology optimization and management measures were adopted in raw material assorting and each production process aim at current problem of worse evenness level of segment-color yarn. Evenness level of segment-color yarn was obviously improved. Evenness CV value was decreased more than 2 percentage points. Thick places and thin places per thousand meter were reduced by 50%. Neps per thousand meters were decreased 40%. It is considered that purpose of improving pure cotton carded segment-color ＇yarn evenness level can be well reached by reasonable cotton assorting,colored cotton quality improvement, blending and pretreatment of main roving raw material,optimization of key technology in each process.
