Abstract of the Disclosure Normally flammable textile fabrics composed of polyamides such as polyhexamethylene adipamides, polycaproamides, poly(m-phenylene- isophthalamides) and the like, are rendered highly flameproof by the intimate association therewith of a flameproofing amount of the reaction product of aqueous phosphoric acid or an acid ammonium phosphate and an alkylene oxide, e.g., ethylene oxide. Amounts of said reaction product of at least, and preferably in excess of 0.5 percent OWF (on the weight of the fiber) increase the Oxygen Index of the treated fabrics to over 40. Preferably the reaction product is rendered neutral before or after application to the fabric and the treated fabrics are non-corrosive, non-irritating in nature, and have a pleasant hand. - 1 -
