METHOD FOR THE SPINNING AND WINDING OF POLYESTER FILAMENTS USING A SPINNING ADDITIVE POLYESTER FILAMENTS OBTAINED BY THE SPINNING METHOD DRAW TEXTURING OF THE POLYESTER FILAMENTS AND BULKED POLYESTER FILAMENTS OBTAINED BY DRAW TEXTURING

摘要

The present invention provides a pre-oriented, comprising polybutylene terephthalate (PBT) and / or polytrimethylene terephthalate (PTMT), preferably PTMT, which is at least 90% by weight of the total weight of the polyester filaments -oriented) in the production and winding of polyester filaments, a) the spinning draft is set in the range of 70 to 500, and b) as soon as the spinning nozzle has just exited, the filament has a length of 30 mm to 200 mm. Passing through the phosphorus cooling delay zone, c) the filaments are cooled below the solidification temperature, d) the filaments converge between 500 mm and 2500 mm from the bottom face of the nozzle, and e) the yarn between the stretch gallons and the stretch gallons. The tension of is set between 0.05cN / dtex and 0.20cN / dtex, f) the thread is wound with a thread tension between 0.05cN / dtex and 0.15cN / dtex, and g) the winding speed is set between 2200m / min and 6000m / min. H) polyester It is characterized in that it is used in combination with an additive polymer as an extensibility increasing agent added at 0.05% to 2.5% by weight based on the total weight of the filament.
