Abstract
An AC electrostatic flocking method having a variable frequency alternating electrostatic field that optimizes flocked product characteristics and/or processing efficiency. The optimized frequency can be determined on-line or from a chart or computerized database containing pre-determined optimized frequencies. The optimized frequency varies depending upon the precursors used and the processing conditions and parameters. Multiple in-line flocking modules having alternating variable frequency electrostatic fields operating at different frequencies may be utilized.
