In the present paper, we investigated the filtration efficiency of polymeric nanofibers mass-produced by modified melt blowing and flash spinning methods. First, the filtration performance of the fiber was experimentally tested by varying the following parameters—fiber thicknesses, filling rate, and fiber diameter. And then, the CFD flow-analyzing software was used to simulate the pressure loss and flow resistivity, these parameters were calculated under the same conditions of filter experiment. It was confirmed that the proposed fiber diameter distribution model was better close to the experimental value than uniform distribution model, and the relations among filling rate, fiber diameters and flow resistivity were also verified. As a result, the proposed model found be useful and the investigated data can be used for making nonwoven fabrics that can then be set as a standard for producing high-performance filters and face masks.
