The melt-blown fabric mainly uses polypropylene as a main raw material, and the diameter of the fiber can reach 1-5 microns. The superfine fibers with unique capillary structures increase the number and the surface area of the fibers per unit area, so that the melt-blown fabric has good filtering property, shielding property, heat insulation property and oil absorption property. The raw material is sprayed with hot air to extrude hot polypropylene from the fine holes of the nozzle of the spinneret to extend in a fibrous form, and then the polypropylene is gathered on a conveyor belt to form a fiber web according to its self-weldability. A plurality of nozzles having a diameter of 0.15mm are arranged on a spinneret, and a molten polypropylene stream discharged from the nozzles is stretched by a high-speed air stream and concentrated on a moving conveyor belt to obtain a meltblown fabric. When the mask is processed by using the melt-blown fabric obtained by processing, the melt-blown fabric sprayed out of the melt-blown machine needs to be cut into strips and rolled, so that the mask is convenient to apply. When cutting the melt-blown fabric, the cutting device needs to be utilized for cutting, and the melt-blown fabric is rolled after cutting.
