摘要：
A process for preparing poly(trimethylene terephthalate) fibers comprising (a) providing a poly(trimethylene terephthalate) composition comprising about 0.05 to about 5 mole % tetramethylene terephthalate repeat units and (b) spinning the polymer composition to form fibers. Poly(trimethylene terephthalate) fiber comprising poly(trimethylene terephthalate) composition comprising about 0.05 to about 5 mole % tetramethylene terephthalate repeat units, as well as yarns, fabrics (e.g., woven, knitted, and nonwoven fabrics) and carpets. A poly(trimethylene terephthalate) composition comprising about 0.05 to about 5 mole % tetramethylene terephthalate repeat units.
