We have laminated polyamide nonwovens with different surface patterns and polypro pylene nonwovens of varying thicknesses and charge them in by a high voltage discharger. We then measure and analyze the remaining surface electrostatic voltage. Our results show that the patterns of nylon nonwovens can affect the residual electrostatic voltage, which increases with the thickness of the nonwovens. The increased surface area in the laminated nonwovens enhances their efficiency in dispersing electrons. These nonwovens can be used in general demands for anti-electrostatic usage.
