A METHOD FOR IMPARTING MINIMUM CARE CHARACTERISTICS TO CELLULOSIC TEXTILES FABRICS THE CELLULOSE FIBERS OF WHICH HAVE AN AVERAGE OF AT LEAST 1.8 FREE HYDROXY GROUPS PER ANHYDRO-GLUCOSE UNIT WHICH COMPRISES THE COMBINATION OF STEPS OF CONTACTING THE FABRIC, UNDER AQUEOUS ALKALINE CONDITIONS, WITH A TEXTILE CREASEPROOFING CHEMICAL CROSS-LINKING WITH THE CROSS-LINKING AGENT A SUFFICIENT PORTION OF THE FREE HYDROXY GROUPS OF THE CELLULOSIC FABRIC WHILE THE FABRIC IS IN AN ESSENTIALLY WATER WET, SWOLLEN CONDITION AND IN AN ESSENTIALLY WRINKLE-FREE CONDITION WHEREBY WET CREASE RESISTANCE IS IMPARTED TO THE FABRIC, AND THEREAFTER IN A SEPARATE STEP ALSO APPLYING TO SAID FABRIC A TEXTILE CREASE-PROOFING RESIN AND AN ACID ACTING CATALYST FOR THE RESIN AND CURING SAID RESIN ON THE FABRIC WHILE SAID FABRIC IS IN AN ESSENTIALLY DRY CONDITION AT ELEVATED TEMPERATURES WHEREBY DRY CREASE RESISTANCE IS IMPARTED TO THE FABRIC.
