Abstract
Compositions of matter are disclosed in which acrylic resins for temporary impregnation of textile fabrics are combined with a laundry sour in aqueous or granular concentrates. These compositions are then introduced to the wash wheel in the last stage of a laundering operation immediately prior to drying the textile fabric. The acrylic resins impart soil release and stain removal properties to the fabrics. Fabric finishing agents may also be included in the compositions.
Claims6
An acidic aqueous concentrate for dispersion in water for use as the final treatment of a laundering process at a pH of about 4 to about 6.5 to impart temporary soil and stain release properties to fabrics consisting essentially of:
- acrylic resin -- 3 to 10 parts, laundry sour -- 3 to 10 parts, coupling and dispersing agent selected from the group consisting of alkyl aryl sulfonates where the alkyl group ranges from C.sub.3 to C.sub.12 and the aryl group is benzene, naphthalene and diphenyl, alkyl sulfonates where the alkyl group ranges from C.sub.10 to C.sub.12 ;
- alkyl sulfates where the alkyl group ranges from C.sub.8 to C.sub.12 ;
- acids and salts of condensed formaldhyde-naphthalene sulfonates where the salts may be sodium, potassium and ammonium;
- salts of sulfonated alkylsuccinic acid where the alkyl group ranges from C.sub.4 to C.sub.8 and where the salts are sodium, ammonium and potassium;
- taurates where the acyl group is oleoyl and coco and the alkyl group is methyl;
- and sodium and potassium salts of alkylether sulfates where the alkyl group may be C.sub.12 or C.sub.13 -- 0.5 to 3 parts;
- fabric finishing agent -- 0 to 1 part and water -- 93.5 to 76 parts, all parts being by weight.
