Abstract: With the combed cotton and bio-based polyamide 56 blended roving as the raw material for the fiber package and N56 filament as the core wire, nine types of 18 tex 70/30 JC/N56/N56 filament(5 tex) Sirofil yarns with the different spaces between roving and filamentand different twists were spun on QFA1528 ring spinning machine installed with a complete condensing spun device, with the roving blending ratio being 70∶30. This paper discussed how the breaking strength, initial modulus, evenness CV and hairiness H of the nine types of Sirofil yarns changed when the distance between the roving and filament and the twists of spinning frame were changed.The results show that when the space between roving and filament is 8 mm and the twist is set at 120.34 twist/10 cm,the yarn strength,evenness and hairiness are optimal.

摘要： 以精梳棉与生物基锦纶56(N56)混纺粗纱作为外包纤维原料,N56长丝作为芯丝,在加装全聚纺装置的QFA1528环锭纺细纱机上纺制粗纱与长丝间距、捻度不同的9种18 tex70/30JC/N56/N56长丝(5 tex)赛络菲尔纱,其中外包粗纱混纺比为70∶30。探讨当改变粗纱与长丝间距和细纱机捻度时,9种赛络菲尔纱的断裂强力、断裂强度、初始模量以及条干CV和毛羽H值变化。结果表明:当粗纱与长丝间距为 8 mm、细纱机设定捻度为120.34捻/10 cm时,所纺纱线的强力、强度、条干和毛羽最优。
