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: In addition to the very time-consuming enzymatic and hydrolytic desizing processes, oxidative degradation of starch size by means of persulfate, to render the starch water-soluble, is conventionally practised. Because of the chemical similarity between starch and cellulose, oxidative degradation of the cellulose is unavoidable in this desizing process. The invention overcomes this problem by breaking up the macromolecules of the starch into dispersible fragments by means of such small amounts of persulfate that neither is the starch made water-soluble nor is the cellulose significantly damaged, the dispersants employed for the fragments being relatively oxidation-stable polymers of unsaturated carboxylic acids.
