Abstract
Abstract The present invention comprises apparatus and process for laundering textiles based upon utilizing quantities of an aqueous liquid wash liquor in the wash step ranging from, at least, just enough to be substantially evenly and completely distributed onto all portions of the textiles to, at most, about 5 times the dry weight of the textiles to be laundered. This results in an extremely efficient use of the detergent composition. The present invention also comprises novel wash liquor and detergent compositions for use in said apparatus and process.

A granular, paste, gel or liquid detergent composition packaged in association with instructions for use in a process for laundering a discrete wash load of assorted soiled textiles, the instructions comprising: (a) produce a quantity of concentrated aqueous wash liquor comprising from about 40% to about 99.9% water and from about 1000 ppm to about 600,000 ppm of the packaged detergent composition; (b) distribute substantially evenly and completely onto said textiles in their substantially dry state a quantity of said wash liquor ranging from about just enough to distribute said wash liquor substantially evenly and completely onto said textiles to a quantity of said wash liquor which is about 5 times the dry weight of the textiles, said wash liquor containing from about 5 grams to about 200 grams of said detergent composition per kilogram of said textiles; (c) allow said wash liquor to remain in contact with said soiled textiles for a period of time during which, if there is more than a minimal amount of free liquor in excess of the absorption capacity of said textiles, only limited amounts of mechanical energy are applied to said textiles so as to prevent oversudsing; (d) rinse said textiles with a quantity of an aqueous liquid, rinse liquor sufficient to produce enough free water on the surface of said textiles to adequately suspend the soil and the detergent composition; and (e) separate said rinse liquor containing said wash liquor and said soil from said textiles.
