Simulation and Experimental Investigations of Fiber Diameter of Spunbonding Nonwovens by Means of the Air Jet Flow Field Model

Abstract:

The air jet flow field models of spunbonding process are founded. It is simulated by means of the finite difference method. The numerical simulation computation results of distributions of the air velocity match quite well with the experimental data. The air drawing model of polymer is solved with the help of the distributions of the air velocity measured by a particle image velocimetry. The predicted filament fiber diameter agrees with the experimental data well.
