Summary: | The invention relates to a method for preparing drug-loaded melt-blown cloth through a vacuum filtration and air drying method and application of the drug-loaded melt-blown cloth. A melt-blown cloth material with micron-sized pores is compact and compact, and ethylene oxide is used for sterilization, so that a user is susceptible to respiratory resistance when wearing a protective mask for a long time, peculiar smell is generated when the protective mask is repeatedly worn for a long time, and the physical and psychological health of the user is influenced. In view of the fact that the melt-blown cloth has the characteristic of strong hydrophobicity and a medicine aqueous solution is difficult to infiltrate and permeate, vacuum negative pressure is firstly applied to medicine liquid on the melt-blown cloth, medicine liquid molecules can rapidly permeate the melt-blown cloth under the condition of vacuum suction filtration negative pressure and are combined with pores in fine fibers of the melt-blown cloth, an |
