ABSTRACT:
An improved melt spinning process for preparing nylon filaments wherein the freshly-extruded filaments enter an enclosed zone that is maintained at superatmospheric pressure by a controlled flow of air at low positive pressure and the filaments leave the zone through a constriction, either a venturi or a tube, assisted by the cocurrent flow of such air at a high controlled velocity.
