第51卷第11期2023年11月CottonTextileTechnology精梳棉纱清梳工艺流程与梳理元件的优选吉宜军崔益怀范正春（南通双弘纺织有限公司，江苏南通，226600）摘要：为了优选精梳棉纱清梳工艺流程与梳理元件，以相同的配棉，分别采用清梳联和清棉成卷+梳棉工艺流程生产JC18.2tex纱，并对梳棉机锡林针布、棉网清洁器、锡林与盖板隔距进行了试验优选，对半制品质量以及成纱质量进行测试。结果表明：锡林针布由AC2030×1550型更换为AC1740×1740型后，梳棉机平均生条AFIS棉结减少，纤维平均长度略有增加，短绒率降低。两种工艺流程的半制品质量基本持平，成纱质量均能达到USTER2018公报5%水平。认为：清梳联实现了工序连续化和自动化生产，可以减少排包次数，节省清棉运棉工，改善生产环境，可进一步提高混棉均匀性；优化配置梳棉针布、工艺隔距、速度等是前纺生产控制棉结和短绒的关键。关键词：清梳联；棉卷；锡林针布；棉网清洁器；盖板；棉结；短绒率中图分类号：TS105文献标志码：B文章编号：1000-7415（2023）11-0076-04Optimizationofblowing-cardingprocessandcardingcomponentforcombedcottonyarnJIYijunCUIYihuaiFANZhengchun（NantongShuanghongTextileCo.，Ltd.，Nantong，226600，China）AbstractInordertooptimizeblowing-cardingprocessandcardingcomponentofcombedcottonyarn，adoptingthesamecottonassorting，JC18.2texyarnwasproducedbyblowing-cardingunitandtraditionalopeningandpickingcottonlapformingprocess.Cylindercardclothing，webcleaner，gaugebetweencylinderandflatofcardingmachinewereoptimized.Thequalityofsemi-productandfinishedyarnweretested.TheresultsshowedthatAFISnepofaveragecardsliverwasreduced，theaveragefiberlengthwasslightlyincreased，andtheshortfibercontentwasdecreasedafterchangingfromAC2030×1550toAC1740×1740.Thequalityofthesemi-productswiththetwoprocesseswasbasicallythesame，andtheyarnqualitycouldreachthe5%leveloftheUSTER2018STATISTICS.Itisconsideredthatafteradoptingblowing-cardingprocess，theuniformityofcottonblendingcanbefurtherimproved.Thekeyofcontrolnepsandshortfibercontentaretheoptimizationsofcardclothing，gaugeandspeed.KeyWordsblowing-cardingunit，cottonlap，cylindercardclothing，webcleaner，flat，nep，shortfibercontent清棉成卷+梳棉和清梳...
