The present invention relates to a method of manufacturing and winding pre-oriented polyester monofilaments consisting of at least 90% by weight relative to the total weight of polybutylene terephthalate polyester monofilament (PBT) and / or polytrimethylene terephthalate (PTMT), mainly PTMT, characterized by that a) complete stretching in the molding process is set in the range of 70-500; b) monofilament immediately after leaving the die passes through a cooling zone and a delay of 30–200 mm; c) the monofilament is cooled below the solidification temperature; g) monofilament unite at a distance of 500-2500 mm from the bottom side of the die; e) the tension of the thread before and between the receiving disks is set from 0.05 to 0.20 cN / dtex; e) the thread is wound with a tension of 0.025-0.15 cN / dtex; g) winding speed set 2200-6000 m / min; h) Polyester is added to which 0.05-2.5 wt.% of the additive polymer is mixed in with respect to the total weight of monofilament as a means of increasing elongation. The international application was published together with the international search report.
