Research on fiber tension in Sirospun spinning triangle

In this paper,the fiber tension distributions in the Sirospun spinning triangle was analyzed by using the finite element method according to the mechanical properties of fibers and the feature of the Sirospun spinning triangle. The effects of spindle speed,traveller and twist factor on the fiber tension distribution in the spinning triangle were analyzed in detail. The results indicate that the spindle speed has the most apparent influence on the fiber tension distribution in the spinning triangle,and the relationship is close between the force applied on fibers in the triangle and the direction of spinning tension,and the yarn twist factor has an important impact on the structure of the spinning triangle. It is considered that combination of the finite element analysis results with the spinning theory of spinning can achieve the optimization of spinning processing parameters,which has some reference value to spinning practice.
