Abstract: Process for the level dyeing of wool, having an anti-felting finish consisting of a coating layer of polyimine or polyamine resin, with reactive dyestuffs, which is carried out according to a graduated temperature exhaustion method from an aqueous liquor using one or several reactive dyestuffs of the formulae ##SPC1##In which F stands for a dyestuff radical having at least 2 sulfonic acid groups linked to an aromatic radical of the chromophore, Z stands for a reactive group of the vinylsulfone, vinylsulfonamide or acrylamide type, n is 1 or 2, and R and R.sub.1 each stands for hydrogen atoms or lower alkyl radicals, in the absence of adjuvants and/or without any pretreatment of the material to be dyed.

Abstract: Process for the level dyeing of wool, having an anti-felting finish consisting of a coating layer of polyimine or polyamine resin, according to the exhaustion method with reactive dyestuffs which contain two or more sulfonic acid or sulfonate groups -- without considering the sulfonic acid or sulfonate groups which may be contained in the fiber-reactive groupings -- in the molecule or with conbinations of such dyestuffs having a different absorbing capacity from an aqueous bath at elevated temperature, in which process benzene sulfonic acids, alkylbenzene sulfonic acids, naphthalene sulfonic acids, alkylnaphthalene sulfonic acids or the condensation products of naphthalene sulfonic acids with formaldehyde or cresols are added to the dyeing liquor.
