Water-soluble textile resin finish

Claim 1

A PROCESS FOR PREPARING AN INFINITELY WATER-SOLUBLE, SUBSTANTIALLY FULLY ETHERIFIED, SUBSTANTIALLY FULLY METHYLOLATED MELAMINE-ETHYLENE UREA-FORMALDEHYDE TEXTILE FINISHING RESIN CHARACTERIZED BY EXCELLENT STABILITY AND SUITABLE FOR USE IN IMPARTING SHRINKAGE CONTROL AND WRINKLE RECOVERY TO CELLULOSE CONTAINING TEXTILE MATERIAL, WITH MINIMUM DELETERIOUS EFFECTS DUE TO CHLORINE RETENTION, WHICH COMPRISES REACTING RELATIVE MOLE RATIOS OF ONE MOLE OF MELAMINE AND AN EXCESS OF FORMALDEHYDE IN AN AMOUNT BETWEEN 8.0 AND 20 MOLES OF FORMALEHYDE AS PARAFORMALDEHYDE AT A TEMPERATURE BETWEEN 30*C. AND 80*C. AND AT A PH BETWEEN 7 AND 11 IN THE PRESENCE OF AT LEAST 6 MOLES OF METHANOL UNTIL A CLEAR SOLUTION IS FORMED AND REACTION IS COMPLETE, ADDING SUFFICIENT ADDITIONAL METHANOL TO THE REACTION MIXTURE TO MAKE A TOTAL OF AT LEAST 10 MOLES OF SAID METHANOL IN THE REACTION MIXTURE, ADJUSTING THE PH OF THE REACTION MIXTURE TO A VALUE BEFOW 4, STIRRING SAID MIXTURE AT A TEMPERATURE OF BETWEEN 15 ADN 60*C. UNTIL A COMPLETE SOLUTION IS OBTAINED, ADJUSTING THE PH OF THE SOLUTION TOBETWEEN 8 AND 10, ADDING FROM BETWEEN 0.6 AND 1.2 MOLES OF ETHYLENE UREA, REACTING SAID ETHYLENE UREA AND SAID EXCESS FORMALDEHYDE TO FORM DIMETHYLOL ETHYLENE UREA AT A TEMPERATURE BETWEEN 30*C. AND 80*C. UNTIL REACTION IS COMPLETE.
