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 in an amount of at least 5 % up to 100% of homogeneously blended curbside post-consumer polyethylene terephthalate by weight and balance virgin polyethylene terephthalate, wherein the homogeneously blended curbside 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 25 ppm, PVC contamination in an amount less than 150 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. |
