Abstract (en)
[origin: DE10151875A1] Production of preoriented and melt spun polyester filaments comprising 90 wt.% of polybutylene terephthalate (PBT) of the total polyester filament weight and/or polytrimethylene terephthalate (PTMT) involves setting the spin draft, cooling directly and bundling together at a gap of 500-2500 mm. Production and winding of preoriented and melt spun polyester filaments comprising at least 90 wt.% of polybutylene terephthalate (PBT) of the total polyester filament weight and/or polytrimethylene terephthalate (PTMT) and is preferably wholly of PTMT. The spin draft is set at 70-500. The filaments are cooled directly on leaving the spinneret for a length of 30-200 mm, to a temperature below the setting point, and bundled together at a gap of 500-2500 mm from the under side of the spinneret. The filament tension before and between the godet rollers is 0.05-0.20 cN/dtex. The filament winding speed is 2200-6000 m/min. The polyester contains a polymer additive to increase its stretch, mixed in at a rate of 0.05-2.5 wt.% of the total filament weight. Independent claims are included for: (1) preoriented polyester filaments which, after four weeks of storage, have a stretch to break of 90-165%, a boiling shrinkage of at least 30%, a normal uster of =1.1%, a double refraction of 0.030-0.058, a density of =1.35 g/cm 3> and preferably =1.33 g/cm 3>, a variation coefficient of the shearing load and stretch to break of =4.5%; and (2) a bulked polyester filament, where the POY yarns are passed through a draw texturizing unit at a speed of at least 500 m/min. with a drafting ratio of at least 1:1.35 to give a bulked filament yarn with a shear strength of >=26 cN/tex and a stretch to break of >=30% or >=36%.
