Resilient fiber mass and method

摘要

A resilient fiber mass and method of forming the same is provided whereby a conventional batting is sprayed with a polyurethane prepolymer and is then in one embodiment rolled into a tight cylindrical shape for subsequent molding. A steam catalyst is introduced into a mold having a specific shape which causes the prepolymer to foam and polymerize. The foaming action separates the fibers at the intersections to provide resiliency to the fiber mass. The molded mass is then removed and can, for example, be attached to a chair seat and covered with decorative fabric as is standard in furniture manufacturing. The chair cushion so formed is highly resilient and durable.
