Abstract

A flame retardant or flame resistant (FR) fiber blend is provided that comprises amorphous silica fibers and at least one FR fiber. A flame retardant fabric, manufactured from a blend of fibers comprises amorphous silica fibers and at least one FR fiber. Barrier fabrics, manufactured from a blend of fibers, are provided comprising amorphous silica fibers and at least one FR fiber.
