Soil retention of aminoplast resin-softener-epichlorohydrin modified cellulosic fabrics obviated by inclusion of carboxymethyl cellulose in reaction system

Claim 1

IN THE PROCESS OF IMPROVING THE WRINKLE RESISTANCE OF A CELLULOSIC TEXTILE MATERIAL BY IMPREGNATING SAID TEXTILE MATERIAL WITH AN AQUEOUS BATH INCLUDING AN AMINOPLAST TEXTILE RESIN, AND ACID ACTING CATALYST AND A SOFTENER, CURING THE RESIN ON THE TEXTILE MATERIAL AND APPLYING A WET CROSSLINKING REAGENT SELECTED FROM THE GROUP CONSISTING OF EPOXIDES, HALOEPOXIDES, HALOHYDRINS AND DIVINYL SULFONES, TO THE TEXTILE MATERIAL WHILE IT IS SWOLLEN AND WET WITH STRONG CAUSTIC, THE IMPROVEMENT WHICH COMPRISES APPLYING TO THE TEXTILE MATERIAL PRIOR TO THE REACTION OF SAID CROSS-LINKING REAGENT THEREWITH, A CARBOXYMETHYL CELLULOSE OR AN ALKALI METAL SALT THEREOF, WHEREBY THE SOIL PICKUP AND RETENTION OF THE TEXTILE MATERIAL IS SUBSTANTIALLY REDUCED WITH CONSIDERABLY LESS SUSCEPTIBILITY TO CHLORINE DAMAGE.
