Abstract:
A dynamic model of the infinitesimal element of the flexible fiber is proposed, which describes the flexible fiber trajectory in the condensing zone of compact spinning with lattice apron. Based on the flow simulation in the condensing zone, the flexible fiber trajectory is simulated by a specially designed Matlab program routine. The trajectories of the fibers of different initial positions can explain the pneumatic condensing mechanism in the condensing zone. The results show that fiber trajectories of different initial positions in the condensing zone gradually converge, and the condensing process of the fiber bundle is divided into three parts: the rapid condensing region, the adjustive condensing region and the steady condensing region. The fibers of different initial positions will be interlaced for position change in yarn cross-section, caused by the airflow in the condensing zone. Moreover, fibers will gradually close the surface of the lattice apron when fibers are delivered from the rapid condensing region to the steady condensing region.
