Numerical Simulation and Experimental Research of Influence of Negative Pressure on Properties of Compact-spun Yarns
The computational fluid dynamic model of compact spinning with lattice apron was established and was computerized with parallel technologies & standard κ-ε turbulent model for simulating and characterizing the flow field in convergence zone of compact spinning with lattice apron. Dynamic model of infinitesimal element of fiber in the airflow filed were established. Trajectories of fibers with different negative pressure were simulated by specially designed MATLAB procedure. Finally, 14.58 tex compact-spun yarn with different negative pressure under the same condition was produced. Both results of simulation and experiment showed that negative pressure is an important parameter to compact spinning, properties of yarn were improved first then decreased with the increase of negative pressure, an optimal negative pressure was obtained to spin 14.58 tex compact-spun yarn on this system.
