摘要：
TRIS(2-CHLOROETHYL)PHOSPHORAMIDE WAS PREPARED FROM ETHYLENEIMINE AND PHOSPHORUS OXYCHLORIDE AND REACTED WITH COTTON CELLULOSE IN THE FORM OF FABRIC BY A PAD-DRYCURE PROCESS IN THE PRESENCE OF A BASIC SALT, SUCH AS SODIUM CARBONATE. REAGENT INCORPORATION LEVELS UP TO 6% BY WEIGHT WERE ACHIEVED. COTTON FABRICS MODIFIED WITH TRIS(2-CHLOROETHYL)PHOSPHORAMIDE WERE FOUND TO HAVE ENHANCED WRINKLE RECOVERY PROPERTIES.
