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.
Claims22
A process for the texturing of yarns of synthetic filaments comprising applying to a synthetic yarn filament 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. in the form of an aqueous emulsion, and false twist texturing the finished yarn in a machine having a short high-temperature heater.
A false twist textured yarn comprising synthetic filaments and 0.25% to 0.45% of a finish comprising:
- (A) a water-soluble lubricant;
- and
- (B) a water-insoluble liquid having a Brookfield viscosity of 2 to 50 mPas at 20° C.
