    IPC: D06P1/22

    Abstract: A process is disclosed for dyeing and printing on textiles made from cellulose fibres or from mixtures of cellulose and other fibres, in an aqueous bath with pH values in excess of 12 and at temperatures of at least 100 DEG C. Use is made of vat dyes without the usual reducing agents for such dyes, in concentrations of alkali hydroxide in the bath of between 20 and 500 ml of aqueous alkaline lye at 38 DEG Bé per litre of bath, dyeing being finished in the normal way.

    Abstract: The invention concerns a process for the reductive post-cleaning of coloured or printed polyester-containing textiles and is characterized in that a mixture is added as a post-treatment agent to the acid dye liquor or the washing bath. Said mixture comprises as components: a) at least one compound of formula (I) Am[(CR R )mSO2M]p,q, in which A designates NR 3-q or OR 2-p, R , R , R designate hydrogen, C1-C6 alkyl, R designates identical or different groups selected from the group comprising hydrogen, C1-C20 alkyl, C3-C8 cycloalkyl, optionally substituted by between one and three C1-C4 alkyl groups, M is an equivalent of an ammonium, alkali or alkaline earth ion, m is 0 or 1, p is 1 or 2, q is 1, 2 or 3, at least one of the groups R , R , R being a C1-C6 alkyl when A stands for OR 2-p, and, when m equals 0: p, q assuming the value 2, and the compound of formula (I) is used in a mixture with an amount of acid-binding substance which is sufficient to increase the pH value of the dye liquor or washing bath by between 1 and 3 units; b) optionally at least one compound of formula (II) A[(CR R )SO3M]p,q, in which A, R , R , R , R , M, p and q have the same general meanings as in formula (I); and c) optionally further additives.
