EFFECTS OF THE CONDUIT GEOMETRY ON THE AIR FLOW FIELD IN THE SPUNBONDING PROCESS

ABSTRACT
In the spunbonding process, the air flow field of the drawing conduit affects the polymer drawing and therefore the filament diameter greatly. Effects of the conduit parameters on the air flow field are studied using the previously established air flow field model. The results show that longer narrow section, longer contracting section and larger height of narrow entry are of benefit to increasing the air velocity, thus helpful for decreasing the filament diameter.
