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.
Claims4
A process for continuously dyeing piece-goods of synthetic fiber materials, which comprises padding the material with an aqueous dyebath at a temperature of from 105.degree. to 135.degree. C and thereafter immediately exposing the material to the action of high-pressure steam at a temperature of from 125.degree. to 145.degree. C to fix the dyestuff completely, said padding and fixing being carried out in a pressure vessel.
