Abstract: The present invention relates to a process for the production and for the spooling of preoriented polyester filaments comprising at least 90 weight %, relative to the total weight of the polyester filament, of polybutylene terephthalate (PBT) and/or polytrimethylene terephthalate (PTMT), preferably of PTMT, characterized in that: a) the spinline extension ratio is set in the range of 70 to 500; b) the filaments, immediately after exiting from the spinning nozzles, pass through a cooling delay zone from 30 mm to 200 mm in length; c) the filaments are cooled off to below the solidification temperature; d) the filaments are bundled at a distance of between 500 mm and 2500 mm from the lower side of the spinneret plate; e) the tension of the thread in front of and between the draw-off galettes is set to between 0.05 cN/dtex to 0.20 cN/dtex; f) the thread is spooled with a tension of the thread of between 0.025 cN/dtex to 0.15 cN/dtex; g) the spooling speed is adjusted to between 2200 m/min. and 3500 m/min.

Abstract: A continuous line for chemical treatment and irradiation of a textile web has an irradiation station provided with an outer protective jacket which has elongated openings for passing through the upper and lower runs of the conveyor. The ray exit window in the range of the outer protective jacket is enclosed by an inner protective jacket defining openings for the upper run of the conveyor supporting the web. To reduce leakage, the inner openings are vertically offset relative to the openings in the outer jacket, and the chains in the upper and lower runs of the conveyor are enclosed in protective casings, of which the upper-run casing is provided with slots for guiding the web. Ray-screening means in the form of displaceable screening blocks are provided in the range of the inner and outer openings and are movable together with the guiding channels.
