摘要： IMPROVED CATALYST SYSTEMS HAVE BEEN FOUND THAT CAN BE USED IN PLACE OF THE CATALYST SYSTEMS PREVIOUSLY REQUIRED TO CURE FLAME-RETARDANT FINISHES FOR CELLULOSE TEXTILES. THESE IMPROVED CATALYST SYSTEMS CONSIST OF A MIXTURE OF ALUMINUM CHLORHYDROXIDE AND AN ACID SELECTED FROM THE GROUP PHOSPHORIC ACID, AXALIC ACID, LACTIC ACID OR A MIXTURE SELECTED FROM THE GOLLOWING: ZINC CHLORIDEGLYCOLIC ACID, MAGNESIUM CHLORIDE-CITRIC ACID, AND MAGNESIUM CHLORIDE-GLYCOLIC ACID. UNLIKE CELLULOSIC FABRICS TREATED WITH THE THP-AMIDE OR THPOH-AMIDE FINISHES WITH OR WITHOUT OTHER CATALYST SYSTEMS, FABRICS SIMILARLY PROCESSED WITH THE IMPROVED CATALYST SYSTEM, THAT IS, THE ONES CONTAINING ALUMINUM CHLORHYDROXIDE HAVE LOWER STIFFNESS VALUE AND A MUCH BETTER HAND.
