摘要: 在系统研究了环锭纺纱机传统的双胶圈弹性钳口牵伸系统的基础上,设计研发了在负压集聚,稳定握持和梯次牵伸方面具有特色的聚纤纺牵伸系统。详细叙述了聚纤纺牵伸系统的作用机制,摩擦力界的仿真设计和实际优化效果。在相同原棉及前纺工艺条件下进行生产对比实验,结果表明采用聚纤纺牵伸系统的成纱条干水平明显优于普通环锭纺和紧密纺,故认为聚纤纺牵伸系统具有大规模推广的价值。

关键词: 聚纤纺, 梯次牵伸, 稳定握持, 摩擦力界, 纱线质量

Abstract: Based on systematic study of the convenitional drafting system with double apron flexible nips of the ring spinning machine, a condensed spinning draft system characterized by negative pressure organization, stable gripping and echelon drawing was designed and developed, and the condensed spinning drafting system mechanism and practical applicattion effect were described. When raw cotton and preparation spinning conditions were identical, experimental results revealed that the condensed spinning drafting system is remarkably superier to the ordinary ring spinning or compact spinning in yarn evenness, so it is worthy to carry out a large-scale promotion of the system.

Key words: condensed spinning, echelon drafting, stable grip, friction circles, yarn quality
