TY - JOUR AU1 - Zhang, Yong AB - With the spread of the novel coronavirus, masks become daily necessities, and their protective effect mainly depends on the core materials, so improving the performance of the core material polypropylene melt-blown nonwoven fabric has become the current research hotspot. The filtration performance of PP melt-blown nonwoven fabric mainly depends on the electret process parameters. The electret treatment of PP melt-blown nonwoven fabric is carried out by using high voltage corona discharge. The research on the influence of the electret process parameters, such as charging time, charging voltage and charging distance, on the filtration performance of PP melt-blown nonwoven fabric will have guiding significance for the practical production. In this paper, after a lot of research and experimental work, find out the influence of process parameters on the filtration performance of nonwoven fabrics. It is found that the best condition for the sample is the charge time of 12 min, the charge voltage of 15 kV and the charge distance of 4 cm. The filter efficiency is 90.2%, which is more than 1.5 times higher than that before the sample. The air permeability of melt-blown nonwovens after electret treatment did not decrease.
