Abstract: A process for the continuous pretreatment of cellulosic textile material comprisesa) a precleaning step wherein the treatment bath used comprises customary surfactants and other customary auxiliaries with or without customary enzymes as desizing agents and has a pH of from 5 to 11, and, after washoff and rinse,b) a bleaching step with hydrogen peroxide in an alkaline-aqueous liquor which comprises customary surfactants and other customary auxiliaries,wherefor the treatment bath of (a) additionally comprises from 1 to 10% by weight, based on the weight of the textile material,(i) either of an aminopolycarboxylic acid, of a hydroxyalkyl- or amino-phosphonic acid, of a polycarboxylic acid, of a polyhydroxycarboxylic acid or of an inorganic polymetaphosphate, or a mixture thereof, as complexing agent for polyvalent metal ions, or(ii) of a water-soluble polymer derived from 40 to 100% by weight of monoethylenically unsaturated mono- or dicarboxylic acids or anhydrides, or a mixture thereof, and has a K value of fr

Abstract: Cotton-containing fabrics are bleached with hypochlorite in an aqueous alkaline liquor at elevated temperatures by a process in which bleaching is carried out at from 80.degree. to 110.degree. C. in the course of from 30 seconds to 25 minutes in the presence of a water-soluble polyhydroxy compound, as a readily oxidizable substance, in an amount of from 0.5 to 20 g/l.

Abstract: Aqueous solutions comprising 25 to 60 percent by weight of mixtures of(a) polymers of acrylic acid and/or copolymers of acrylic acid with maleic acid and(b) aminopolycarboxylic acids, aminopolyphosphonic acids and/or hydroxyalkanepolyphosphonic acids,such solutions having a pH value of about 3 to about 7 with the acid groups being present 20 to 80 percent in the form of the potassium salts and the remaining acid groups being present in form of the free acid, the amine salt, or mixtures thereof.
