Background

The mask is a sanitary article, generally refers to a device which is worn at the mouth and nose part and used for filtering air entering the mouth and nose so as to prevent harmful gas, smell and spray from entering and exiting the mouth and nose of a wearer, and is made of gauze or paper and the like. The mask has a certain filtering function on air entering the lung, and has a very good effect when being worn in respiratory infectious diseases and working in environments polluted by dust and the like. The mask may be classified into an air filtering type mask and an air supplying type mask. The first gauze mask to be used in the world is China. The dust-blocking efficiency of the mask is based on the dust-blocking efficiency of the mask on fine dust, particularly respiratory dust below 2.5 microns. Because the dust with the particle size can directly enter alveoli, the influence on human health is the largest. The gauze mask adopts the dust blocking principle of mechanical filtration, namely, when dust collides with gauze, large-particle dust is blocked in gauze through layer-by-layer blocking. For some fine dust, especially dust less than 2.5 microns, it will pass through the mesh of the gauze and enter the respiratory system. The dust mask consists of active carbon fiber felt or non-woven fabric as filtering material, and the respiratory dust smaller than 2.5 micron is made to pass through the filtering material.
