Abstract: Disclosed is a fiber composition comprising from about 60 wt. % to about 99 wt. % of a polymer base resin, wherein the polymer base resin comprises a chemically upcycled polybutylene terephthalate (PBT) component, which was derived from a post-consumer recycled (PCR) polyester, and from about 0.1 wt. % to about 40 wt. % of a reinforcing filler, wherein the combined weight percent value of all components does not exceed 100 wt. % and all weight percent values are based on the total weight of the fiber composition, wherein the fiber composition is in the form of a fiber, and wherein the fiber exhibits a tensile modulus of greater than 1950 MPa when tested in accordance with ISO 527.
