主 题:compact spinning with lattice apron simulation dynamical model trajectory additional twists
摘 要:Based on the flow simulation in the condensing zone of compact spinning with lattice apron and a bead-elastic rod dynamic model of the flexible fiber,trajectories of fibers with different negative pressure are simulated by specially designed Matlab *** displacement components of fibers at YZ profile under different negative pressure conditions are extracted and *** results show that the fibers of different initial positions gradually converge,and are interlaced for position change in yarn cross-section,caused by the airflow in the condensing ***,compact-spun yarn with different negative pressure and conventional ring spun yarn are produced and their twists are *** the results of simulation and experiments illustrate the existence of additional *** the relationship between additional twists and negative pressure is verified.
