Neutralization Efficiency of the electrostatic charges on the surface of the fibrous media by the dual electrode system and the triode system

: In this work we present the results of the active neutralization of electrostatic charges on the free surface of a fibrous dielectric polypropylene by two electrode systems. The objective of this work is to compare the efficiency of neutralizing electrostatic charges by two electrode systems; electrodes dual-plan system and the triode system. The results permit to determine the influence of the grid on the neutralizing efficiency to enhance the active neutralization of charge method, applied to the fibrous dielectric materials. The neutralization efficiency is obtained by the non-contact sampling of profiles of the surface potential before and after neutralization. The experiments were performed on 120 mm x 90 mm samples cut from the same nonwoven polypropylene (PP) fabric. The samples…
