Abstract
Systems for manufacturing bulked continuous carpet filament from polymer, where the systems are configured for: (1) passing polymer flakes through a crystalliers; (2) melting the polymer to create a first single stream of polymer melt; (3) separating the first single stream of polymer melt into multiple streams of polymer melt; (4) exposing the multiple streams of polymer melt to a pressure of between about 0 millibars and about 25 millibars in a chamber; (5) recombining the multiple streams of polymer melt into a second single stream of polymer melt; and (6) providing the second single stream of polymer melt to one or more spinning machines that are configured to form the second single stream of polymer melt into bulked continuous carpet filament.
