摘　　要：为了顺利生产Outlast腈纶混纺针织纱,分析了Outlast腈纶纤维的性能特点,并在纺纱过程中针对性地采取了工艺技术改进措施。通过纺纱前喷洒抗静电剂;清梳工序适当降低各打击梳理机件速度,放大梳理隔距;并条工序采用"重加压、大隔距、轻定量"工艺原则;粗纱工序选用较小的后区牵伸与较大的罗拉隔距;细纱工序在较大粗纱捻系数的基础上,采用较大的后区隔距、较小的后区牵伸、低速度等工艺;各工序严格控制温湿度,结果成功纺制出棉/Outlast腈纶60/40 18.3 tex混纺针织纱,达到了较好的质量水平。To produce Outlast acrylic blended knitting yarn successfully,the characteristics of Outlast acrylic liber were analyzed, processing technology modification measures in spinning were adopted accordingly. Through splashing an- tistatic agent before spinning, properly reducing each beater speed and increasing carding gauge in carding, adopting heavier pressure, larger gauge, lighter weight per unit in drawing, selecting smaller back draft multiple and larger gauge in roving, adopting larger back gauge and smaller back draft based on bigger roving twist factor in spinning, strictly controlling temperature ＆ humidity in every process et al,finally cotton/Outlast acrylic 60/40 18.3 rex blended knitting yarn can be spun successfully,the quality can be reached better level.
