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 out at temperatures between 80° and 120°F. Preferred ion donating sources are sodium bromide and sodium hypochlorite. If desired, the sodium bromide may be compounded with conventional detergent formulations.

在较低温度下在水中漂白纺织材料和减少的时间间隔worin的方法：将溴化物离子源被加入到水中以1和25ppm的之间赋予初始浓度; 氯离子源被加入到水中，在25和90ppm的之间的初始浓度以产生; 洗涤水和织物材料被搅拌，在30秒至5分钟之间的时间间隔; 和漂白的纺织品被回收。 该过程可以在温度80℃和120°之间F.优选的离子供源是溴化钠和次氯酸钠携带。 如果需要清除，溴化钠可以与常规洗涤剂式蒸发散混。
