Recycled polyethylene terephthalate compositions, fibers and articles produced therefrom, and methods for producing same

A fiber consisting essentially of a polyester polymer composition, wherein the polyester polymer composition comprises:

• a) post-consumer polyester;
• and
• b) at least one impurity resulting from use of the post-consumer polyester in a consumer product prior to recovery for recycling,
• wherein the at least one impurity is not present in virgin polyester, and wherein the fiber is homogeneous.
