摘　　要：为提高纺纱质量和生产效率,以纺36.4 tex、CJ 14.6 tex、粘胶/棉50/5027.8 tex+77.7 dtex弹力纱、C 36.4 tex+77.7 dtex弹力纱等为例,通过统计数据对比分析钢丝圈圈型、截面形状及使用时间对千锭时断头、毛羽指数及千米棉结的影响。指出:瓦楞形、宽半圆形及圆背扁脚截面的钢丝圈纺纱,磨损少、散热快,钢丝圈运行稳定性较好,产生的棉结少;低弓形钢丝圈适纺细号纱,通道左右适中,质心低且运行平稳;高弓形钢丝圈质心高、运行不稳定、散热性能差,适纺粗号低车速纱;钢丝圈使用周期长,成纱千锭时断头、毛羽指数及千米棉结指标变差;钢丝圈选型及使用周期确定,应结合纺纱品种及指标要求统筹考虑,同时在纺纱过程中做好清洁。In order to improve spinning quality and production efficiency,taking the spinning of 36.4 tex,CJ 14.6 tex,viscose/cotton 50/5027.8 tex+77.7 dtex elastic yarn,and C 36.4 tex+77.7 dtex elastic yarn as examples,a comparative analysis is conducted using statistical data to examine the impact of ring type,cross-sectional shape,and usage time on yarn breakage in per thousand spindle hour,hairiness index,and neps per kilometer.It is pointed out that the spinning with corrugated shape,wide semicircle shape and round back and flat foot section ring has less abrasion,faster heat dissipation,better operation stability and less neps.Low bow shape ring is suitable for spinning fine yarn,with moderate left and right channel,low mass center and stable operation.High bow shape ring has high mass center,unstable operation and poor heat dissipation performance,and is suitable for spinning coarse low spinning speed yarn.When the ring has a long service life,the yarn quality indicators such as yarn breakage in per thousand spindle hour,hairiness index,and neps per kilometer tend to worsen.The selection of ring type and determination of its service life should be considered comprehensively based on the type of yarn and the requirements of yarn quality indicators.Meanwhile,proper cleaning should be carried out during the spinning process.
