ABSTRACT:
Rapid dyeing process for piece-goods, especially knit fabrics, of synthetic fibre materials, preferably of texturized polyester fibers, by padding the material with an aqueous dyebath in a pressure vessel, which may be used both for the application and fixation of the dyestuff, at first under high-temperature (HT--) conditions and then exposing the material immediately after this operation to the action of high-pressure (HP)-- steam to fix the dyestuff completely.
