Among the SMS structure of a face mask, the middle lining of meltblown nonwoven fabric plays the most important role of viruses and bacteria filtration, it must filter more than 95% of micro-particles in air with diameters below 2.5 micron, otherwise the Face Mask will be a fiasco and will Not have any efficiency at all for face protection!
The first step to make a meltblown nonwoven fabric of highest quality is to choose the right material - Polypropylene raw material with Melt Flow Index of 1500 g/10min. Besides MFI, other technical data such as Moisture Content and Volatile Constituents of the material also matter in meltblown process, last but not least, the quality of material must keep stable for continuous mass production.
