-15- FIRE BARRIER FABRIC Abstract A fire-resistant fabric suitable for use as a flame barrier comprising a flame durable textile fabric substrate formed of corespun yarns, the yarns comprising a core of flame resistant filament and a sheath of staple fibers, and an intumescent coating carried by one surface of the textile fabric substrate. In normal use, the fabric is flexible and conformable and has good air porosity. When exposed to high temperature and/or a flame, however, the intumescent coating reacts and swells to form a char which closes the pores or interstices of the fabric to thus prevent flame or hot gases from penetrating therethrough.
