Electric charging of nonwoven materials employed as filter media improves their particle collection efficiency by the electrostatic particle capture mechanism that enhances the conventional mechanical filtration without causing an increase of the pressure drop. The aim of this paper is to provide a better understanding of the corona-charging process of such(More)
Surface potential and electric field measurement techniques are widely used for the investigation of the corona charging of dielectric surfaces in a wide range of industry applications. The aim of this paper is to estimate which of these techniques are the most appropriate for characterizing the charging state of nonwoven fibrous dielectrics and point out(More)
The aim of this paper is to analyze the corona charging and charge decay of nonwoven fabrics, by using the surface potential decay (SPD) measurement techniques and its (tdVs/dt) versus (log t) representation. Samples of nonwoven polypropylene (PP) fibrous media were exposed to negative corona discharges, using a triode-type electrode arrangement, energized(More)
