ABSTRACT:
A process for producing industrial denier filaments of a thermoplastic polymer at higher rates of production than those using liquid quenching media is disclosed. Liquid polymer is extruded in the form of hollow filaments at a throughput and rate of take up that produces individual filaments of greater than about 30 denier. A flow of gas is then directed at the liquid filaments at a flow rate and temperature that are sufficient to quench and solidify the individual filaments in the absence of any other quenching fluid. The filaments formed by the disclosed process have larger diameters than solid filaments of the same denier.
