Melt blown fabric is a kind of cloth made of polypropylene as the main raw material. Its fiber diameter can reach 1-5 microns. These ultra-fine fibers with unique capillary structure can increase the number and surface area of fibers per unit area, so that the melt blown cloth has good filtration, shielding, heat insulation and oil absorption, and can be used for air and liquid filtering materials, isolation materials and absorption Materials, mask materials, thermal materials and wipes and othe
