Abstract:
A nonwoven fabric formed of polyethylene glycol modified copolyester staple fibers that provide exceptional moisture management characteristics, said copolyester staple fibers comprising:polyethylene terephthalate in an amount sufficient for said 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 said 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, the standardized polymer being unmodified polyethylene terephthalate; wherein said copolyester staple fibers have a mean intrinsic viscosity of at least about 0.67 dl/g.
