Meltblown nonwoven fabric is made from a special technique for manufacturing non woven fabric with very fine fibers. The melt-blown non-woven fabric is an important component for making face masks that protect medical workers from the new coronavirus. This melt-blown filter fabric is the key part of respirators that can provide the majority of the protection. It can be widely used in a disposable respirator, surgical masks, face masks, re-used dust respirators, and surgical respirators. As the virus spreads around the world, those face masks are in short supply.
