Abstract (en)

[origin: DE19718977A1] The invention relates to a method of decolorizing textiles during washing, using an oxidation system dispersed or dissolved in water, said oxidation system containing one per-acid precursor, a source of H2O2, and a catalyst which catalyses the reaction of the per-acid precursor and the source of H2O2. The per-acid formed is provided to the suds at such a speed that there is always enough per-acid available as is required for decolorizing the stain.
