Abstract:
1. A method for producing a sewing thread, comprising pretwisting two or three yarn components independently of one another, whereby each yarn component has an elongation at break between 25% and 85% and an elastic tensile elongation between 30% and 95% of the elongation, determined by a measuring strength, corresponding to 70% of the absolute strength of the respective sewing thread, twisting the pretwisted yarn components with one another to form a plied thread and subjecting the plied thread to thermal treatment, whereby the two or three yarn components are pretwisted with a twist value α between 50 and 130 and whereby the pretwisted yarn components are twisted with one another with a twist value α′ between 80 and 160.
