Claim 17:
18. A method for manufacturing a carpet, the method comprising:
obtaining PET flakes substantially from a mix of both non-clear and clear PET bottles;
providing a PET crystallizer;
passing the PET flakes through the PET crystallizer to at least partially dry at least a portion of a surface of the PET flakes;
after passing the PET flakes through the PET crystallizer, at least partially melting the PET flakes into a polymer melt;
increasing a surface area of the polymer melt by extruding the polymer melt into at least eight streams;
passing the at least eight streams of polymer melt into an interior of a chamber such that a respective surface area of each of the at least eight streams is exposed to a chamber pressure below atmospheric pressure;
recombining the at least eight streams into a single polymer stream;
producing carpet yarn at least by forming the single polymer stream into continuous bulked carpet filament;
dyeing the continuous bulked carpet filament; and
using the carpet yarn for producing said carpet.
