Methods for manufacturing bulked continuous filament

A method of manufacturing recycled polymer, the method comprising:

• separating a polymer melt into at least eight streams such that each of the at least eight stream is at least partially exposed to a chamber pressure within a chamber of less than about 5 millibars;
• after the at least eight streams are exposed to the chamber pressure of less than about 5 millibars, recombining the at least eight streams into a single polymer stream;
• and
• forming polymer from the single polymer stream into recycled polymer.

A method for purifying a plurality of recycled polymer flakes, the method comprising:

• providing a pressure regulation system;
• using the pressure regulation system to reduce a chamber pressure within a chamber to below about 5 millibars;
• melting the plurality of recycled polymer flakes to create a polymer melt;
• after using the pressure regulation system to reduce the chamber pressure to below about 5 millibars, providing the polymer melt to the chamber;
• increasing a surface area of the polymer melt exposed to an interior of the chamber utilizing at least four different streams of the polymer melt;
• while the at least four streams of the polymer melt are within the chamber, exposing each of the at least four streams of the polymer melt to the chamber pressure of below about 5 millibars;
• after exposing each of the at least four streams of the polymer melt to the chamber pressure of below about 5 millibars, recombining the at least four streams into a single stream of purified recycled polymer.
