摘要
为探索高倍转杯竹节纱的可纺性,以过渡段捻度传递长度为研究对象,推导过渡段纱线参数变化理论模型,并对捻度传递长度变化情况进行模拟。通过双喂给双分梳转杯纺纱器成功纺制出高倍竹节纱,并对成纱物理性能进行测试。研究结果表明:过渡段长度设定为1个转杯周长时,高倍转杯竹节纱的过渡段捻度传递长度始终大于4 mm,捻度传递长度满足过渡段纺纱的连续性需求,也证实了高倍转杯竹节纱的可纺性;且制备的高倍转杯竹节纱质量较好,纱线平均断裂强力随竹节倍数的增加而增加,断裂伸长率无显著变化,但毛羽较多,后续开发可就此展开针对性的研究。
To explore the spinnability of high-ratio rotor spinning slub yarns,the peripheral twist transmission length of transition section was taken as the research object.A theoretical model for the variation of yarn parameters in the transition section was built,and the changes of the peripheral twist transmission length were simulated.High-ratio slub yarns were successfully spun using the dual-feed dual-combing rotor spinning device,and the physical properties of yarns were tested.The research results indicated that,assuming a transition section length of 1 rotor circumference,the peripheral twist transmission length of the transition section of high-ratio rotor spinning slub yarns was consistently greater than 4 mm,which met the continuity requirements for spinning in the transition section,and confirmed the feasibility of spinning of high-ratio rotor spinning slub yarns.Moreover,the prepared high-ratio rotor spinning slub yarns had good quality.The average breaking strength of the yarns increased with the increase of the slub multiple,the breaking elongation rate showed no significant change,but there were more hair fibers.Further development can focus on conducting targeted research on this regard.
