melt blowing air-drawing nonwovens polypropylene modelling
2009/6/17
Computer simulation of the pneumatic melt spinning of isotactic polypropylene based on the mathematical model of the process is presented. Two dynamic zones of the air jet-filament interactions along ...
A Computational Fluid Dynamics Modeling and Experimental Study of the Mixing Process for the Dispersion of the Synthetic Fibers in Wet-Lay Forming
Mixing Process Synthetic Fibers Wet-Lay Forming
2009/3/6
In this paper, we present results from a computational fluid dynamics (CFD) model for the mixing process used to disperse synthetic fibers in wet-lay process. We used CFD software, FLUENT, together wi...
Mathematical Modeling of Pneumatic Melt Spinning of Isotactic Polypropylene. Part. I. Modeling of the Air Jet Dynamics
fiber spinning melt blowing nonwoven computational fluid dynamics turbulence
2009/2/19
In this series of publications, the process of nonwoven melt blowing of ultra-fine fibers is presented. The process starts in the dual slot die where two converging air jets draw the molten polymer st...
