Abstract
A fire-resistant material used in items such as sleeping bags, comforters, wearing apparel, upholstered furniture and mattress tops comprises a fiberfill batt and a layer of a fire-resistant aramid fiber contacting at least one side of the aramid fiber layer. The fiberfill batt may comprise synthetic fiber, which may be either polyester fiber or polyolefin fiber. Alternatively, the fiberfill batt may comprise natural fiber. The aramid fiber layer may comprise poly(m-phenylene isophthalamide) fiber, poly(p-phenylene terephthalamide) fiber or a blend of poly(m-phenylene isophthalamide) and poly(p-phenylene terephthalamide) fiber. The aramid fiber layer may be needle-punched, hydroentangled, or laminated to the fiberfill batt.
