Numerical Approach to the Convergent Point of Rotor-Spun Composite Yarn

摘要

The convergent point is of crucial importance to the characteristics of rotor-spun composite yarns. Quasistatic model, linear dynamic model and nonlinear dynamic model are established for rotor-spun composite yarn spinning process. By the established models, we can easily determine the position, the trajectories and phase diagram of convergent point. The presented studies shed light on the understanding of the motion for rotor-spun composite yarn's convergent point.
