Abstract
A fabrous material is impregnated with a treating agent comprising (1) a tetrakishydroxymethyl phosphonium compound or an ammonium condensate of a tetrakishydroxymethyl phosphonium compound, (2) methylolmelamine and (3) urea, thiourea or a guamidine salt, and the fabric is heated with high-pressure steam or subjected to a microwave heat treatment in the pressure of water vapor. A high and durable flame retardancy can be imparted to the fibrous material by this treatment. Especially good results are obtained when a fibrous material composed of a mixture of a polyester fiber and a cellulose fiber is treated according to this method.
