Experimental and Simulation Investigation on the Effect of Slot Angle on the Flush Sharp Die Performance during Melt Blowing

다국어 초록 (Multilingual Abstract)

Die configuration is one of the most important factors that determine the polymer jet attenuation during meltblowing. To find the optimum slot angle, we investigated the effects of sharp die slot angles (60 °, 50 °, 40 °) on the polymerjet attenuation experimentally and numerically. A model which incorporated the air-polymer coupling effect was built basedon phase field method to investigate the die performance. In the experiment, sharp dies with different slot angles werefabricated and adopted for producing melt-blown nonwovens. The SEM and filter efficiency measurement, and numericalanalysis demonstrated that the 60 ° sharp die has the best performance in polymer jet attenuation.
