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 (tdV s /dt) versus (log t) representation. Samples of nonwoven polypropylene (PP) fibrous media were exposed to negative corona discharges, using a triode-type electrode arrangement,(More)
— The surface potential decay (SPD) measurement is a commonly-used method for monitoring the charge state of non-woven dielectric media for air filtration applications. The aim of this paper is to evaluate the factors that influence the SPD rate of a specific class of filtering media: " M1 " consisting in two layers of non-woven polypropylene (PP) attached(More)
