Abstract (en)

[origin: ES8602166A1] Process for desizing of cotton and cotton contg. fabrics in strongly alkaline aq. solns. with alkalihypochlorite in which are added 0.5-8 g/l of an aq. alkaline soln., of soluble tertiary hydroxyalkylamine, oxyethylated polyethylene imine, malonic acid, cyanuric acid or deriv. urea deriv. cyanoguanidine, oxazolidone, pyrrolidine, N-methylpyrrolidone or N-methylimidazole or their mixts. as activators for the hypochlorite. Pref. the activator is cyanuric acid, oxazolidone, N-methyl pyrrolidone, or N-methylimidazoline.
