In one aspect, the invention relates to recycled polyethylene terephthalate compositions, fibers and articles produced therefrom, and methods for producing same, the composition comprising polyethylene terephthalate present as from 25% to 100% of homogeneously blended deposit post-consumer polyethylene terephthalate by weight and balance virgin polyethylene terephthalate, wherein the homogeneously blended deposit post-consumer polyethylene terephthalate comprises at least one impurity not present in virgin polyethylene terephthalate; and wherein the at least one impurity comprises floatable contamination in an amount less than 15 ppm, PVC contamination in an amount less than 50 ppm, or a combination thereof. In a further aspect, the invention relates to homogenized post-consumer polyethylene terephthalate. In a further aspect, the invention relates to extruded polymer compositions, polymer mixtures, fibers, and/or Bulked Continuous Filament fibers comprising post-consumer polyethylene terephthalate. In a further aspect, the invention relates to processes for preparing recycled polyethylene terephthalate compositions. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention. |
