TY - JOUR TI - Polymer drawing in the unsymmetrical air flow of melt blowing: Numerical simulation AU - Wu Li-Li AU - Ma Yao AU - Chen Hua-Jun AU - Chen Ting JN - Thermal Science PY - 2014 VL - 18 IS - 5 SP - 1699 EP - 1700 PT - Article AB - 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.
