Abstract
A process for the continuous dyeing of textile materials consisting of or containing wool with reactive dyestuffs according to a steam fixation method, by impregnating the fibrous material at pH values of from 6.5 to 7.5 with an aqueous liquor containing reactive dyestuffs of the methyltaurino-ethyl-sulphone type, and fixing the dyestuff without intermediate drying of the material by treating with saturated or largely saturated steam at temperatures of from 110.degree. to 120.degree. C.
