Abstract (en)
[origin: US2005147784A1] The present invention relates to a process for spinning poly(trimethylene terephthalate) filaments/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. It is spun and the filaments are converged into yarn. The filaments have a denier greater than 1 and the yarn has a denier greater than 210.
