Abstract
Abstract A flame-retardant material, and a method for making same, which comprises: (1) a reinforcing ply of textile material; (2) at least one sheet of foam bonded to a face of the reinforcing ply; (3) a layer of flock fibers adhered to the foam thereby covering the exposed face of the foam; and (4) a flame-retardant adhesive system disposed in two layers between said flock fibers and the foam sheeting.
