Abstract
A method of recycling a PET-containing material comprises: (1) providing an MRS extruder having an MRS section comprising a plurality of satellite screws and an outlet; (2) providing a vacuum pump in communication with the MRS section; (3) providing a spinning machine comprising an inlet, wherein the inlet is directly coupled to the outlet of the MRS extruder; (4) heating a plurality of PET-containing flakes in the MRS extruder to form a PET-containing melt; (5) increasing a surface area of the PET-containing melt by distributing the PET-containing melt across the plurality of satellite screws in the MRS extruder; (6) drawing off vapors from the PET-containing melt by reducing the pressure in the MRS section with the vacuum pump; (7) collating the PET-containing melt in the MRS extruder; and (8) extruding the PET-containing melt through the outlet of the MRS extruder into the inlet of the spinning machine.
