Beschreibung
Zusammenfassung:	"PRODUCTION OF TEXTILE MATERIALS" Black, flame-resistant, substantially inert, nonconductive, 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 in which X is oxygen, sulphur or -NH-, and Z is -NH2, -NHCN, -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 phosphorous, heating the impregnated textile in an oxygen-containing gas to a temperature of 220.degree. - 300.degree.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%.
