Abstract (en)
[origin: EP0019862A1] 1. A process for the uniform dyeing of textile piece goods made from mixtures of cellulosic fibers and synthetic polyamide fibers and, if desired, additionally elastomeric fibers on polyurethane basis, according to the pad-steam technique, which comprises padding onto the foregoing defined textile material aqueous padding liquors containing sulfur dyestuffs, alkaline reducing agents and certain metal-complex dyestuffs and/or acid dyestuffs being selected due to the result of an experimental dyeing test as specified in the descriptive part, and fixing simultaneously the said dyestuffs on that fiber component of the blend which is appropriate to the respective dyestuff type by steaming at 100 degrees to 110 degrees C in the course of 30 seconds to 10 minutes, whereupon the reoxidation of the applied sulfur dyestuffs present in the leuco-form is performed in usual manner.
