【摘要】 论文分析了集聚区须条的运动,研究了集聚纺纱集聚区纱条的附加捻度、总捻度与吸风口管斜槽倾角及纺纱速度的关系,提出附加捻度T1=（sinβ）/（2πr）,总捻度T=（dinβ）/（2πr）+（n₂）/（v_纱）,并用试验验证该模型的可行性。更多还原

【Abstract】 Based on the analysis on the motion of fiber band in compact field of compact spinning,a mathematic model is proposed to describe the relationship between additional twists, final twists,diameter of the fiber band in the compact field,tilting angle of suction slot in profile tube and spinning speed.The validity of the model is proved by compareing the final twists of the ring spun yarn and compact spun yarn.更多还原
