This thesis deals with the theoretical analyses and the preliminarily experimental research of the collecting spinning, which decreases the twist-triangle-area to control the hairiness of the yarn by congregating the yarn through setting a collector in an accessorial collecting zone ahead the quondam main draft zone.
对细纱机增加集合区、通过集合器的集合作用减小加捻三角区,从而对控制纱线毛羽的集合纺纱技术进行了初步的理论分析和实验探讨。

Comparison test on different accessories and different processes regarding uneveness and more fuzzy yarn of spinning yarn shows that lower CV value requires reasonable selection of drafting process,roller space,roving twist factor and good cot while lower fuzzy yarn requires reasonable selection of guiding hook,spindle,and collector plus rings and travelers.
针对细纱条干不匀和毛羽较多的问题 ,通过选用不同器材采用不同工艺进行对比试验 ,指出要降低细纱条干CV值需合理选择牵伸工艺、罗拉隔距、粗纱捻系数和胶辊 ;要减少细纱毛羽需合理选配导纱钩、锭子、集合器和钢领、钢丝圈。
