Analysis of the Additional Twists on the Fiber Band in Compact Field of Compact Spinning

摘要

Based on the analysis of the motion of fiber band in compact field, a mathematic model is proposed in this article. The factors affecting the additional twists and final twists of the compact spun yarn, such as diameter of the fiber band in the compact field, tilting angle of suction slot in profile tube and spinning speed, were discussed in detail. The validity of the model was validated by experiments.
