POLYMER DRAWING IN THE UNSYMMETRICAL AIR FLOW OF MELT BLOWING: NUMERICAL SIMULATION

ABSTRACT
The unsymmetrical air flow of the dual slot die in the melt blowing process is simulated. The diameter and transverse displacement of the threadline are obtained numerically. The result shows that the threadline diameter in the unsymmetrical air flow is larger than that in the symmetrical one. This paper helps to point out the research direction for producing finer melt blown fibers.
