Abstract: The present invention relates to a process for the simultaneous stretch-texturing of synthetic, at least partly thermoplastic filaments or yarns using false twisters, more especially friction false twisters wherein the ratio S2/S1 between the tractive or tensile forces S1, acting on the filament before the false twister, and S2, acting on the filament after the false twister, is adjusted to from 1.0 to 1.4 by adapting the ratio between the rotational speed of the false twister and the rate of travel of the filament or yarn, and the denier-related twisting of the yarn is from 5 to 50% higher than the level of twisting which is normally applied in conventional false-twist texturing processes using a spindle and which can be calculated on the basis of the Heberlein formula. Moreover, the invention relates to a yarn produced by the afore-described process.
