Abstract

Abstract 1. A process for the continuous dyeing and printing of wool fibers with reactive dyes containing sulfo groups, in the presence of an alkali metal acetate and without the application of a textile auxiliary agent according to a pad-rapid steaming method or a print-rapid steaming method, characterized in that the wool fiber material to be dyed or printed is padded with an aqueous dyebath containing sodium acetate in the range of from 60 to 100 g per liter of liquor in addition to the dissolved dyestuffs, or is printed with an aqueous print paste containing sodium acetate in the foregoing mentioned amount per kilogram of paste, and after a short intermediate drying, said pad dyeing or print is subjected to a treatment with saturated steam at a temperature in the range of from 102 to 115 degrees C for 30 to 180 seconds, to fix the dyestuffs.
