    Abstract: A process for reduction clearing dyed or printed polyester textiles, which comprises adding, to an acidic dyeing liquor or a wash bath, an aftertreatment composition comprising as componentsa) at least one compound of the formula (I)where A is NR 3-q or OR 2-p; p,q means q when A is NR 3-q, and p when A is OR 2-p; R , R , R are each hydrogen or C1-C6-alkyl; R represents identical or different radicals selected from the group consisting of hydrogen, C1-C20-alkyl, C3-C8-cycloalkyl opt. substituted by from one to three C1-C4-alkyl radicals; M is the equivalent of an ammonium, alkali metal or a kaline earth metal ion; m is 0 or 1; p is 1 or 2; and q is 1, 2 or 3, subject to the provisos that at least one of R , R , R is C1-C6-alkyl when A is OR 2-p and that, if m is 0: the compound of formula (I) is S2O4M2, and the compound of the formula (I) is used together with sufficient acid acceptor to raise the pH of the dyeing liquor or of the wash bath by from 1 to 3 units,b) optionally at least one compound of the formula (II)where A, R , R , R , R , M, p,q p and q are each as defined for the formula (I), although the specific choice of these variables does not have to be the same for the compounds of the formulae (I) and (II)c) and optionally further additives.

    Abstract: The disclosure is a process for batchwise dyeing of cellulosic textile material with indigo by the exhaust method, which comprises applying the reduced indigo to the textile material from an aqueous dyeing liquor which includes a reductant, an alkali and additionally a further dissolved alkali metal salt in a concentration of from 200 to 350 g/l as electrolyte and whose pH has been set to 10.2-11.3, oxidizing the reduced indigo on the fiber back to the pigment while maintaining the high electrolyte concentration, and finishing the dyeing in a conventional manner.

    Abstract: Concentrated leuco indigo solutions useful for dyeing cellulosic textile material consist essentially of from 25 to 55% by weight of leuco indigo in the form of the leuco indigo salt, an amount which is essentially stoichiometrically sufficient to convert the leuco indigo into the neutral leuco indigo salt of a mixture of at least two alkali metal hydroxides wherein none of the alkali metal hydroxides accounts for more than 70 mol %, and water.
