聚纤纺牵伸系统的研究与实践

Research on condensed spinning draft system

针对传统环锭纺纱机双胶圈弹性钳口牵伸机构的缺陷,设计研发了在负压机构设置,稳定握持和梯次牵伸3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牵伸原理、作用机制和实际应用效果。在相同原棉及前纺工艺条件下进行生产及对比实验。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,聚纤纺牵伸系统具有大规模推广的价值。

Based on systematic study of the convenitional drafting system v^ith 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 application 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-scare promotion of the system.
