Abstract
A flame-retardant fabric 1 of the present invention comprises: a fiber fabric 4; and a back layer 5 formed on the back surface of the fiber fabric 4 and containing at least one of inorganic compound selected from the group consisting of calcium carbonate and magnesium hydroxide, thermally expansive graphite and a polymer substance. The adhering amount of solid of the back layer 5 is 50 to 150 g/m.sup.2. The adhering amount of the thermally expansive graphite is 15 to 60 g/m.sup.2. The adhering amount of the inorganic compound is 10 to 60 g/m.sup.2. The flame-retardant fabric causes no generation of noxious substances in case of fire and at incineration disposal, can impart sufficient initial flame retardancy, and has excellent flame-retardant performance in heat aging.
