Abstract: Cotton and cotton-containing fabrics are desized in strongly alkaline aqueous solution with an alkali metal hypochlorite by a process in which from 0.5 to 8.0 g/l of a tertiary hydroxyalkylamine which is soluble in aqueous alkaline solution, of an oxyethylated and/or oxypropylated ethylenediamine, of an oxyethylated polyethyleneimine, of malonic acid, of cyanuric acid, of a cyanuric acid derivative, of a urea derivative, of cyanoguanidine, of oxazolidone, of pyrrolidone, of N-methylpyrrolidone, of N-methylimidazole or of a mixture of these is added to the aqueous bath, as an activator for the hypochlorite. Activators for hypochlorite are used in the desizing of cotton and cotton-containing fabrics in strongly alkaline aqueous solutions.

Abstract: An agent, based on reducing agents and complexing agents, for dissolving insoluble iron(III) compounds in aqueous textile treatment baths which are at a pH of 10 or more, which agent has the following composition: (a) from 4 to 65% by weight of one or more water-soluble hydroxycarbonyl compound or of an N- or O-acetal thereof, as the reducing agent, (b) from 10 to 80% by weight of one or more complexing agent which complexes Fe++ ions at a pH of 10 or more and (c) water in an amount equal to 100% minus the amounts of (a) and (b).

Abstract: Production of water-sol?ble crosslinked auxiliari?s for the papermaking industry by reacting(a) one equivalent of NH groups of a polyalkylene polyamine having from 15 to 500 alkyleneimine units with(b) from 0.001 to 0.08 mole of a reaction product obtained from a polyalkylene oxide having from 8 to 100 alkylene oxide units with epichlorohydrin, in aqueous solution at a temperature of from 20.degree. to 100.degree.C. The viscosity of an aqueous solution containing 20% by weight of the crosslinked auxiliaries is from 300 to 1,500 centipoises (20.degree.C).

Abstract: A process for coloring paper with an acid dye and/or direct dye in an aqueous medium in the presence of a water-soluble reaction product of an alkylating agent, possessing an aromatic substituent, with a cationic polyelectrolyte. The process gives papers with high color strength and substantially avoids cylinder twosidedness of the coloration.
