Abstract
A sewing thread made of synthetic fibers is described, whereby the ready-to-use sewing thread has an elongation at break between 25% and 85% and an elastic tensile elongation of between 30% and 95% of the elongation, determined by a measuring strength, corresponding to 70% of the absolute strength of the respective sewing thread. In addition, two methods for making a sewing thread are also described, whereby the sewing thread comprises either a plied yarn or an air-intermingled sewing thread. To produce this sewing thread yarn components with an elongation at break between 25% and 85% and an elastic tensile elongation of between 30% and 95% are selected, whereby thermal and preferably hydrothermal treatment is carried out after the actual yarn production.
