Fire Combustion Modified Batt

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.
