<p>A fire-resistant fabric suitable for use as a flame barrier comprising a flame durable textile fabric substrate (20) formed of corespun yarns (10), the yarns (10) comprising a core (11) of flame resistant fiber and a sheath (12) 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.</p> |
