CA 1107915

Abstract of the Disclosure A process is provided for flameproofing cellulose containing fiber material which is dyed with copper-complex azo dyes. In this process the fiber material is heated with an aqueous composition containing (a) a dialkylated phosphono-propionic acid amide or its N-methylolated derivate (b) an alkanolamine such as a 2-amino-2-alkyl-1-alkanol (c) a water-soluble copper salt such as copper (II) chloride or sulphate (d) optionally an aminoplast precondensate or an etherified aminoplast pre-condensate such as methylolated or melamines or their alkyl ethers. The treated fiber material is dryed (e.g. up to 120°C) and then subjected to a heat treatment at e.g. 140 to 200°C.
