Black, flame-resistant, substantially inert, non-conductive, flexible textile materials are produced by impregnating a scoured regenerated cellulosic textile material with a composition containing (a) a compound having in one tautomeric form, the general formula [Figure] in which X is oxygen, sulphur or -NH-, and Z is -NH2, -NHGN, -NH.NH2, -NH.CO.NH2 or lower alkyl or X and Z taken together represent a trivalent nitrogen atom, and (b) an ammonium salt of an oxy-acid of phosphorus, heating the impregnated textile in an oxygen-containing gas to a temperature of 220°-300°C. until a black, flame retardant product is obtained and there has been a loss in weight based upon the original weight of the textile material, of 20% to 30%.

A process for the production of a black, flame-resistant, substantially inert, non-conductive flexible textile material which comprises impregnating a regular regenerated cellulosic textile material with a composition consisting essentially of (a) at least one compound having, in one tautomeric form
A process for the production of a black, flame-resistant, substantially inert, non-conductive flexible textile material which comprises impregnating a regular regenerated cellulosic textile material with a composition consisting essentially of (a) at least one compound having, in one tautomeric form, the general formula [Figure] in which X is selected from O, S and -NH-and Z is selected from -NH2, -NHCN, -NHNH2, -NHCONH2 and lower alkyl groups or X and Z taken together represent a trivalent N atom, and (b) at least one ammonium salt of an oxy-acid of phosphorus, and thereafter heating the impregnated textile material in an oxygen-containing gas to a temperature within the range of 220°to 300°C. to effect a controlled oxidation thereof until a loss in weight, based upon the weight of the original textile material, within the range of 20 to 30% has occurred.
