摘要：
A method of manufacturing bulked continuous carpet filament that includes providing a polymer melt and separating the polymer melt from the extruder into at least eight streams. The multiple streams are exposed to a chamber pressure within a chamber that is below approximately 5 millibars. The streams are recombined into a single polymer stream and formed into bulked continuous carpet filament.
