Method of forming flocked articles
Abstract
Abstract A flocked article and method for making the same comprising centrifugally extruding thermoplastic strands or filaments of any desired thickness and length, and then impinging the rapidly moving strands or filaments on a substrate base of any desired material or combination of materials immediately after said strands or filaments are freed from an extrusion die. Direct fusion bonding of the strands or filaments to the substrate may be achieved, or bonding of the strands or filaments may be obtained by applying an adhesive or hot melt layer to the substrate base prior to impinging them thereon, or by using a heat softened thermoplastic substrate. Unique flocking apparatus is obtained by using a centrifugal extruder in combination with other means of forming the substrate base. Also, a novel flocked article may be achieved by the penetration of one end of the strands or filaments into the matrix of the substrate base prior to their bonding or fusion therewith.
