摘要
对苎麻复精梳工艺中的苎麻预并条和头道精梳条进行牵切,然后将这两种牵切条分别与纯棉条进行条混纺纱,并对牵切、并条、粗纱和细纱各工序的工艺进行探讨。分析细纱断裂强度与捻系数的相互关系,确定了牵切纱临界捻系数在445左右,其小于同线密的苎麻/棉常规纱的临界捻系数。
In this paper, pre-drawing slivers and the pre-combing slivers of ramie were stretch-broken into slivers, and then both of the slivers were blended with pure combed cotton slivers. The processes of stretch-breaking, drawing, roving and spinning were discussed. Based on the relationship between breaking strength and twist factor, it is determined that the critical twist factor of stretch-breaking yarns is 445, which is smaller than that of regular ramie/cotton blended yams of the same linear density.
