WASHING METHODS UTILIZING AN EFFERVESCENT PRODUCT ADDED PRIOR TO AGITATION

摘要

A method of laundering soiled textile articles comprising an initial step of adding a granular detergent composition consisting essentially of an effervescence granule and a detergent matrix to water to form an aqueous wash liquor comprising from about 400 ppm to about 600000 ppm of the granular detergent composition. The effervescence granule comprises and alkali-source and an acid-source and upon contact of the granular detergent composition with water a reaction occurs between the alkali-source and the acid-source occurs to produce an effervescent gas. In a second step a cleaning-effective amount of the wash liquor is distributed substantially evenly and completely onto the textile articles in their substantially dry state.
