PROCEDURE FOR SPINNING AND COILING POLYESTER FILAMENTS, WHICH CAN BE OBTAINED BY THREADING PROCEDURE, STRETCH TEXTURING OF POLYESTER FILAMENTS, AS WELL AS POLYESTER FILAMENTS THAT CAN BE OBTAINED THROUGH THE TEXTURE.

摘要

Procedures for manufacturing and winding preoriented polyester filaments, composed of at least 90% by weight based on the total weight of the polyester filament by polybutyleneterephthalate (PBT) and / or polytrimethylene terephthalate (PTMT), preferably by PTMT, characterized in that a) is adjust the degree of stretch of the yarn in the range of 70 to 500, b) the filaments travel directly after the exit of the spinneret a cooling delay zone between 30 mm and 200 mm in length, c) the filaments are cool below the solidification temperature, d) the filaments are intertwined at a distance between 500 mm and 2500 mm from the bottom of the nozzle, e) the thread tension is adjusted before and between the development rollers between 0.05 cN / dtex and 0.20 dtex, f) the thread is wound with a spinning tension between 0.025 cN / dtex and 0.15 cN / dtex, g) and the winding speed is set to between 2200 m / min and 3500 m / min,
