PP is the main raw material of the melt blown fabric, and the diameter of the fiber can reach 0.5-10 μ m. These ultra-fine fibers with unique capillary structure increase the number and surface area of the fiber per unit area, so that the melt blown fabric has good air filtration, which is a relatively good mask material. In large and medium-sized medical institutions, in SARS and avian influenza with the high incidence season of H1N1 virus, melt blown filter fabric plays an irreplaceable role with its strong filtering performance.
