What are the advantages of non-woven masks

Masks generally refer to appliances worn on the mouth and nose to filter the air in the mouth and nose to prevent harmful gases, odors, and droplets from entering and leaving the wearer's mouth and nose. They are mostly made of cloth or paper. The most commonly used are non-woven masks.

The outer layer of the mask often accumulates a lot of dust, bacteria and other contaminants in the outside air. Usually, it is best to prepare a few more masks for replacement. It should be changed and washed once a day. The dust blocking efficiency of non-woven masks is based on the blocking efficiency of fine dust, especially respiratory dust below 5 microns. Because dust of this particle size can directly enter the alveoli, it has the greatest impact on human health. The dust blocking principle of general gauze masks is mechanical filtration, that is, when the dust collides with the gauze, some large particles of dust are blocked in the sand cloth through layers of barriers.

However, for some fine dust, especially dust less than 5 microns, it will pass through the mesh of the gauze and enter the respiratory system. At present, there are some dust masks abroad. The filter material is composed of fibers charged with permanent static electricity. In the process of passing through the filter material, those respirable dust smaller than 5 microns are attracted by electrostatic attraction and adsorbed on the filter material to capture fine particles. Dust, really play a role in preventing dust. The anti-side leakage design of the mask is to prevent the air from being inhaled through the gap between the mask and the human face without being inhaled through filtering. Air is like water flow, where there is less resistance, it flows first. When the shape of the mask does not fit closely with the face, the dangerous substances in the air will leak in from the non-contact and enter the respiratory tract of the person. So, even if you choose a mask with the best filter material. Nor can your health be guaranteed. Many foreign regulations and standards stipulate that workers should regularly test the tightness of masks. The purpose is to ensure that workers choose the right size mask and wear the mask according to the correct steps.
