Background
The mask is an air filtering device, and the existing disposable medical mask is generally composed of three layers of materials, namely an inner-outer spun-bonded layer material and an intermediate melt-blown material. The inner and outer spun-bonded layers are made of polypropylene mostly, and most of dust and particles can be filtered. The intermediate layer melt-blown material has smaller gaps, can filter smaller particles, and adsorbs tiny bacteria and viruses through the electrostatic adsorption effect of the melt-blown layer, so that the viruses or bacteria are prevented from entering respiratory tracts.
When the mask is worn for a long time, the melt-blown layer can adsorb and accumulate a large amount of bacteria and viruses. Bacteria and viruses can pass through the mask to enter the human body without death. If the medicine is placed on the melt-blown layer, viruses and bacteria can be effectively killed, but the electrostatic adsorption effect of the melt-blown layer can be damaged by tiny particles in the medicine, and particularly, the static electricity of the melt-blown layer is greatly reduced or disappears by the medicine spraying in a liquid mode. This results in poor filtration.
