Abstract:
A method for cleaning greatly soiled textiles with organic solvents and aqueous detergent solutions consisting essentially of (1) contacting greatly soiled textiles with a cleaning liquor consisting of a customary water-immiscible, organic dry-cleaning solvent and an aqueous solution of a detergent composition containing from 3.5% to 35% by weight of said solution of an anionic surface-active compound with a low solubility in said organic dry-cleaning solvent, wherein from 0.5 to 10 gm of said detergent composition are present per liter of said cleaning liquor for a time sufficient to clean said soiled textiles and to have said textiles absorb said aqueous solution, (2) removing the soiled organic dry-cleaning solvent from said textiles containing absorbed aqueous solution, (3) contacting said textiles containing absorbed aqueous solution with water for a time sufficient to completely wash said textiles, (4) rinsing said textiles with water, and (5) recovering said cleaned textiles.
