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.
