    摘要： A process for preparing poly(trimethylene dicarboxylate) multifilament yarns and monofilaments. One process for preparing poly(trimethylene dicarboxylate) multifilament yarns includes (a) providing a polymer blend including poly(trimethylene dicarboxylate) and about 0.1 to about 10 weight % styrene polymer, by weight of the polymer in the polymer blend, (b) spinning the polymer blend to form poly(trimethylene dicarboxylate) multiconstituent filaments containing dispersed styrene polymer, and (c) processing the multiconstituent filaments into poly(trimethylene dicarboxylate) multifilament yarn including poly(trimethylene dicarboxylate) multiconstituent filaments containing styrene polymer dispersed throughout the filaments. Another process includes spinning at a speed of at least 3,000 m/m and processing a blend including poly(trimethylene dicarboxylate) to form partially oriented poly(trimethylene dicarboxylate) multifilament yarn. A poly(trimethylene terephthalate) yarn including poly(trimethylene terephthalate) multiconstituent filament containing styrene polymer dispersed throughout the multiconstituent filament. The invention is also directed to uses of the filament yarns and monofilament.
