摘要

In this paper, a linear dynamic model was established for rotor-spun composite yarn spinning process by force analysis. Numerical approach to the model was calculated. By simulating the trajectories and phase diagrams of convergent points of staple fibers and filaments, the stability of rotor-spun composite yarn spinning process was obtained, which is effective to improve the efficiency of production. The presented study provides a general pathway to understand the motion of convergent point during rotor-spun composite yarn spinning process.
