Abstract: A high loft fiber batt is formed from a blend comprising charred thermoplastic fibers and about 10-15 percent by volume polyester binder fibers, wherein the fiber batt is suitable for use as a fire barrier layer. Another embodiment of a high loft fiber batt is formed from a blend of at least 15 percent by volume charred thermoplastic fibers, at least 15 percent by volume polyester carrier fibers, and about 10-15 percent by volume polyester binder fibers. Still another embodiment of a high loft fiber batt comprises a blend of about equal amounts by volume of charred thermoplastic fibers and polyester carrier fibers, wherein the fiber batt is suitable for use as a fire barrier layer. These high loft fiber batts may be used as a fire barrier layer in various different products, including seating and insulation for vehicles and aircraft, bedding, upholstery and furniture.

Abstract: The present invention relates to a method for forming a bi-layered carpet underlay. More particularly, the method includes bonding a layer of non-woven fibers and a layer of re-bonded foam particles together to form the bi-layered carpet underlay. The layers of the carpet underlay can be bonded together with the use of adhesives, by heating a surface of one or both layers to a soft bondable state for lamination between the layers, by applying a film having adhesive surfaces between the layers, or by other suitable bonding means. The bi-layered carpet underlay combines the soft cushioning resilience of foam with the high durability bridging ability of fiber to provide a carpet underlay that maintains its height or thickness and firmness, while imparting softness and cushioning effects over an extended period of wear.

Abstract: A seat cushion or other resilient structure includes a foam inner core combined with layers of varying density fiber batts to impart desirable comfort characteristics, support features and durability thereto. In one embodiment, the foam core is positioned between intermediate layers of low loft fiber batts of relatively high densities. In turn, the intermediate batts are sandwiched between outer high loft fiber batts having relatively low densities. Alternately, the foam core comprises one or more intermediate layers of relatively high density fiber batts that are positioned within the foam core to create one or more fiber batt subcores. The outer high loft fiber batts sandwich the foam core comprising the fiber batt subcores to create the resilient structure.

Abstract: A protective fire retardant (FR) component for a composite furniture system. The protective FR component includes a resilient FR fiber batt comprised of at least one FR material and a layer of material enclosing the resilient FR fiber batt. The FR materials used to form the resilient FR fiber batt may include oxidized polyacrylonitrile (O-PAN) fibers, FR rayon fibers, a fiber blend which includes both O-PAN fibers and FR rayon fibers, modacrylic fibers or a fiber blend which includes both FR rayon fibers and modacrylic fibers.

Abstract: The present invention relates to a method for forming a fire combustion modified batt. The method comprises the step of forming a blend of nonwoven and oxidized polyacrylonitrile fibers into a web. The oxidized polyacrylonitrile fibers are fire resistant and when blended with nonwoven fibers are relatively easily processed into a batt. A second blend of nonwoven fibers can be formed into a web and layered with the oxidized polyacrylonitrile fiber web to form the batt. The fibers are bonded together with heat, resin or other bonding material and are compressed and cooled. The fire combustion modified batt is useful as fire barriers and fillers in bedding, upholstery and vehicle and aircraft seats, as insulators for apparel, appliances, walls and ducting, as barriers to separate control systems from a heat source, and as components in fire safety gear such as race driver suits and oven and welding mitts.

Abstract: A fire resistant (FR) mattress comprising a core comprising a first densified nonwoven fiber batt, and a ticking comprising a first fabric, the ticking enclosing the core and the fill layer, wherein the core and the ticking consist essentially of a common fiber composition having substantially identical FR characteristic, thereby imparting the substantially uniform FR characteristic upon the mattress. In another aspect, the invention includes a mattress comprising a core, a plurality of substantially adjacent similarly oriented spring coils arranged in a common plane within the core, and a ticking comprising a first fabric, the ticking enclosing the core and the fill layer, wherein the core and the ticking consist essentially of a common fiber composition having substantially identical FR characteristic, thereby imparting the substantially uniform FR characteristic upon the mattress.
