Abstract
Disclosed is a nonwoven fabric that is formed of polyethylene glycol modified copolyester staple fibers. The copolyester staple fibers include polyethylene terephthalate in an amount sufficient for the copolyester staple fibers to possess dimensional stability properties substantially similar to those of conventional, unmodified polyethylene terephthalate fibers, polyethylene glycol in an amount sufficient for the copolyester staple fibers to possess wicking characteristics 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. Also disclosed are methods for making such nonwoven fabrics.
