Abstract

The invention relates to a process for the high-speed false twist texturing of yarns of synthetic filaments, in which a finish containing at least one water-soluble lubricant (A) and one water-insoluble liquid (B) with a viscosity of 2 to 50 mPas at 20° C. is applied to the yarns in the form of an aqueous emulsion, after which the filaments are textured on the false twist principle in texturing machines with a short high-temperature heater.
