Paper Title:
Investigation of Fiber Diameter in Spunbonding Process via Mathematical Modeling
  Abstract

The polymer air-drawing model of polypropylene (PP) spunbonding nonwovens has been established. The influence of the density and the specific heat capacity of polymer melt at constant pressure changing with polymer temperature on the fiber diameter have been studied. The effects of the processing parameters on the final filament fiber diameter have also been investigated. A lower polymer throughput rate, a higher polymer melt temperature, a higher primary air temperature, a higher primary cool air velocity, and a higher air suction speed can all produce finer fibers, while fiber diameters first decrease with increases in the venturi gap and then increase with increases in the venturi gap.
