羊毛/派丝特/羊绒半精纺紧密赛络纱的生产技术

对羊毛、派丝特、羊绒纤维的性能进行了分析,利用新型紧密赛络纺技术开发了27.8 tex羊毛/派丝特/羊绒(50/45/5)半精纺纱线。详述了原料的预处理、和毛、梳棉、并条、粗纱、细纱、络筒等工序的主要生产工艺与技术措施,并对紧密赛络纺技术工艺参数的优选做了详细的说明,指出了其技术关键是控制双槽入口间距和吸风负压的大小,并从理论方面对于紧密赛络纱的强度增大、条干降低、毛羽减少的原因作了简要的分析。通过合理配置工艺参数,能够充分发挥紧密赛络纺的优点,纺出了性能优良的半精纺紧密赛络纱。

Processing technology of semi-worsted compact siro yarn spun with wool/Paster/cashmere

The characters of wool,paster and cashmere are analyzed,and the compact siro spinning method is used to develop wool/Paster/cashmere(50/45/5)27.8 tex and semi-worsted spinning yarn.This paper gives detail introduction about the major production technique and measures in terms of pretreatment of raw material,interlot,combing,drawing,roving,spinning,winding and so on.It introduces the preferences of technological parameters of the compact siro spinning.Meanwhile,it must be pointed out that the emphasis of the...
