摘要: Poly(trimethylene terephthalate) is formed into a bulk continuous filament yarn by process including: (a) melt-spinning poly(trimethylene at temperature within the range of about 240 to 280° C. produce plurality spun filaments; (b) cooling (c) converging filaments yarn; (d) drawing first draw ratio 1.01 2 in stage defined least one feed roller and roller, each said operated less than 100° heated greater temperatures 50 150° C.; (e) subsequently second 2.2 times that 100 200° winding drawn yarns, after optionally texturing yarns. The invention enables production terephthalate)-based carpet having resiliency nylon as well stain resistance low static generation polyester.
