INTRODUCTION
Spunbonding is a single step process for converting plastic pellets into nonwoven fabrics, which dates back to 1950's [1-4]. Almost all thermoplastic resins can be processed on spunbonding equipment. The molten polymer is extruded through a series of fine spinneret holes and is drawn (attenuated) by the action of high velocity cool air [5-7], the process is so rapid, it has been shown that the drawing occurs mainly through air drawing. Researchers have been devoting attention to study air drawing model of polymer, especially Spruiell and coworkers [8, 9]. However, the reported air drawing models mentioned above were not based on numerical computation ...
