VERFAHREN ZUM BLEICHEN BEI TIEFER TEMPERATUR MIT REDUZIERTEN MENGEN AN CHLOR UND VERKUERZTE BLEICHZWISCHENZEITEN ERFORDERND.

摘要

A method of bleaching textile materials in water at lower temperatures and reduced time intervals wherein: a source of bromide ions is added to the water to impart an initial concentration between 1 and 25 ppm; a chlorine ion source is added to the water to yield an initial concentration between 25 and 90 ppm; the wash water and textile materials are agitated for an interval between 30 seconds and 5 minutes; and the bleached textiles are recovered. The process may be carried at temperatures between 80 DEG and 120 DEG F. Preferred ion donating sources are sodium bromide and sodium hypochlorite. If desired, the sodium bromide may be compounded with conventional detergent formulations.
