Electrostatic Flocking

Electrostatic flocking utilizes an electric charge to orient fibers and promote their perpendicular alignment. This technique optimizes the results obtained with longer fiber. In this method, the adhesive coated substrate passes through a high voltage electrostatic field. An electrode is utilized to give the flock fiber a charge. The charged fibers become aligned with the electric field lines of force and are attracted to the grounded electrode. The flock moves towards the adhesive coated substrate and becomes embedded. Fibers are adhered perpendicular to the surface giving a dense, pile finish. The electrostatic flocking method can be enhanced with pneumatic techniques for good coverage on three dimensional objects.
