This study is about random fiber arrangements of the roller card in nonwovens processed by different voltages and electrode panel shapes. Samples are hot pressed, then photographed by a microscope. According to the results, changing the shape of the electrode panel can provide better random effects when the same voltage is used. The results indicate that the best panel shape has circular holes and is positioned between the cylinder and doffer. The optimum random effect occurs when the original panel is electrified with 2 kV between the cylinder and the doffer, or the panel with circular holes is electrified with 20 kV and placed over the conveyer belt.
