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.
