Finishing process incorporating improved catalyst systems to produce durable flameproofed cellulosic textile products with an excellent hand
Abstract
Abstract 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.
