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 fiber and a sheath of modacrylic intumescent staple fibers. In normal use, the fabric is flexible and conformable and has good air porosity. When exposed to high temperature or a flame, however, the modacrylic intumescent sheath fiber 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.
