Meltblown Fabric Electret,Why Masks Keep Out Microbes
Meltblown cloth is a melt-blown nonwoven cloth formed by drawing the polymer melt trickle extruded from the die spinneret orifice with high-speed hot air flow, thereby forming superfine fibers and collecting the superfine fibers on a screen or roller, and simultaneously bonding the superfine fibers by itself. These superfine fibers with unique capillary
