摘要： The present invention relates to processes using poly(trimethylene terephthalate) filaments (2)/yarn. The poly(trimethylene terephthalate) has a number average molecular weight of at least about 26500 and a melt viscosity of at least about 350 Pascals at 250°C and 48.65 per second shear rate. The poly(trimethylene terephthalate) is spun into filaments (2) and the filaments (2) are converged into yarn. The filaments have a denier greater than 1 and the yarn has a denier greater than 210.
