Abstract: Process for the dyeing of nitrogen-containing fibers, preferably wool, with reactive dyestuffs by treating the goods with aqueous baths of such reactive dyestuffs with which the nitrogencontaining fibers react according to an addition mechanism and which have been converted into a more soluble and more reactive form by the action of N-alkyl-amino-alkyl carboxylic acids and/or N-alkyl-amino-alkyl-sulfonic acids or their salts.
