Abstract

The invention is related to a false twister for the production of synthetic textured or stretch-type yarns or filaments, consisting of two or more successive internal friction twisters, wherein the inlet-end friction surfaces of the internal friction twister mouthpieces have a high coefficient of friction whilst the friction surfaces of the outlet mouthpieces have a low coefficient of friction in relation to the friction surfaces at the inlet end.
