What is the production process of meltblown non-woven fabrics for masks?

The production process of melt-blown non-woven fabrics for masks is as follows. Using raw materials such as polypropylene, polyester, polyamide, etc., the polymer resin is extruded and melted, and then accurately metered by a metering pump into a special melt distribution cavity, and then the polymer resin is extruded and melted. After rectification, it enters the spinning melt pool, and the melt is ejected from the spinning micro-holes.
