Abstract
Process for the continuous dyeing of high-quality polyester fibers, wherein on the textile material, which has been impregnated with a dyeing liquor, the dyestuff applied is fixed by means of a combined treatment with saturated vapor at high pressure and a wet treatment at high temperature.
Claims7
A process for the continuous fixation of heat-fixable dyestuffs on flat surfaces of texturized polyester fibers, wherein the textile material impregnated with the dyestuff is subjected, in a pressure-tight closed system and tension-free, to a combined treatment with a saturated vapor at an excess pressure of from 1 to 4 atmospheres and a wet treatment, the temperature of the treating liquor corresponding to the pressure of the saturated vapor.
