  • Patent number: 7329043
    Abstract: An apparatus for testing properties of a product comprising a thermal barrier layer comprises an ignition source, a test stand that extends a sample of the product over the ignition source, and a means for measuring thermal transfer across the sample. The apparatus may further comprise a means for measuring thermal transfer across each layer of the sample. A method for testing properties of a product comprising a thermal barrier layer comprises supporting a sample of the product over an ignition source, heating the sample via the ignition source, and determining a thermal differential across the sample. The method may further comprise determining a thermal differential across each layer of the sample.

  • Patent number: 7238630
    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.

  • Patent number: 7132022
    Abstract: A bi-layered fire resistant (FR) nonwoven fiber batt and an associated method for manufacturing the same. The bi-layered FR nonwoven fiber batt includes a first, gray, FR layer, formed from a blend of black oxidized polyacrylonitrile (oxidized PAN), white dry polyester carrier fibers and white low-melt polyester binder fibers, and a second, white, layer, formed from a blend of white FR rayon, white dry polyester carrier fibers and white low-melt polyester binder fibers, disposed in a conforming relationship with the first, gray, FR layer.

  • Patent number: 7125460
    Abstract: Disclosed are uni-layer and bi-layer FR nonwoven fiber batts formed of various blends of charring fibers such as FR treated rayon, oxygen-depleting fibers such as modacrylic fibers and nonwoven fibers such as carrier fibers and binder fibers and associated methods for forming the same. Variously, the uni-layer and bi-layer FR nonwoven fiber batts may include layers formed entirely of blends of charring fibers and nonwoven fibers, layers formed entirely of blends of oxygen-depleting fibers and nonwoven fibers and/or layers formed of blends of charring fibers, oxygen-depleting fibers and nonwoven fibers.
