Abstract
The method of using polyfunctional quaternary ammonium compounds which are at least substantially insoluble in an aqueous fabric detergent solution and/or are fixed to solids correspondingly insoluble in such aqueous solution, as a soil-collecting, concentration-reducing agent for reducing the demand for conventional detergent components in the aqueous solution.
Claims10
A process for laundering or cleaning soiled textile material comprising treating said textile material in an aqueous detergent wash bath whereby pigmented or fatty soils are loosened from said soiled textile material, and contacting said wash bath with a polyfunctional quaternary ammonium compound which is insoluble or is fixed to a solid which is insoluble in said wash bath, said polyfunctional quaternary ammonium compound having a counter-ion which has been at least partly replaced by a surface-active agent, to collect from said wash bath at least a portion of said soils loosened from said textile and thereby reduce the demand for conventional detergent components in said wash bath, said polyfunctional quaternary ammonium compound being in the form of a finely-divided, particulate solid having a maximum average particle size of about 100 microns.
