摘　　要：在细特纱的纺纱过程中,为了减少细纱断头,提高成纱质量,对细纱牵伸部件及工艺配置进行了分析,发现将前上罗拉加大一定前冲量后能减小细纱无捻三角区,并在FA506型细纱机上进行了前上罗拉前冲工艺试验,结果表明,合理选用前冲量能优化纺纱工艺,对降低细纱断头,改善成纱质量有明显效果。To spinning fine tex yarn, the draft parts and processing technology arrangements are analyzed to reduce the spun yarn breaking rate and improve the formed yarn quality. It is found that dashing-forward certain amount of the draft parts on spinning frame can reduce the twistless triangle area. And corresponding experiments on FA506 spinning frame prove that a properly dashing forward of the front upper roller position optimizes the spinning process and remarkably improves the formed yarn quality.
