  • Flame retardant fiber blends comprising flame retardant cellulosic fibers and fabrics and garments made therefrom
    Publication number: 20050025962
    Abstract: An intimate blend of staple fibers has from 10 to 75 parts by weight of at least one aramid staple fiber, from 15 to 80 parts by weight of at least one flame retardant cellulosic staple fiber, and from 5 to 30 parts by weight of at least one polyamide staple fiber. The intimate blend of staple fibers provides yarns and fabrics that are flame retardant, also referred to as fire resistant, and can be used to make flame retardant articles, such as clothing. The flame retardant fabrics may have a basis weight from 4 to 15 ounces per square yard.
