Abstract
Disclosed is a polyethylene glycol modified copolyester fiber that has exceptional moisture management characteristics and that can be formed into exceptionally comfortable fabrics. The copolyester fiber includes polyethylene terephthalate in an amount sufficient for the copolyester fiber to possess dimensional stability properties substantially similar to those of conventional, unmodified polyethylene terephthalate fibers, polyethylene glycol in an amount sufficient for the copolyester fiber to possess wicking properties that are superior to those of conventional, unmodified polyethylene terephthalate fibers, and chain branching agent in an amount less than about 0.0014 mole-equivalent branches per mole of standardized polymer.
