A brief introduction to non-woven fabrics
There are two kinds of non-woven fabrics, one is made of pure cotton absorbent gauze or knitted fabric, and the center is various non-woven fabrics. The other is directly sewn from non-woven fabrics. The filtering effect is good, but the air permeability is poor. Mask non-woven fabrics are made of non-woven materials on the outside and back, and filter paper in the center, which makes the filtering effect of mask non-woven fabrics reach a higher level.
Therefore, when choosing and using non-woven masks for masks, some manufacturers' products provide you with the convenience that you can use the same mask body and need protection in dusty work environments. When it is dusty, it can be equipped with the corresponding filter cotton, so wear a non-woven mask; when you need to defend in a toxic environment, please replace the filter cotton and install the corresponding chemical filter box to make it effective, maybe according to your The job needs to give you more combinations.
The dustproof efficiency of mask non-woven fabrics is based on their blocking efficiency against fine dust, mainly about inhalable dust below 5 microns. Since dust of this size can directly enter the alveoli, it has a great impact on human health. Regarding general gauze masks, the principle of dust prevention is mechanical filtration, that is, when dust hits the gauze, it will pass through several layers of barriers, and some large dust particles will be blocked by the sand cloth.
However, some fine dust, especially dust smaller than 5 microns, can pass through the mesh of the gauze and enter the respiratory system. There are some dust masks abroad, and the filter material is composed of electrostatically charged fibers. When passing through the filter material, the inhalable dust smaller than 5 microns is attracted by static electricity and adsorbed on the filter material, which does have a dust-proof effect.
Air moves like water with very little resistance. When the shape of the mask non-woven fabric is not close to the face, harmful substances in the air will leak from the non-closed part and enter the human respiratory tract. Therefore, even if we choose masks with filtering materials. Nor does it maintain your health. There are many foreign regulations and norms, and workers should regularly test the adhesion of non-woven fabrics for masks. The purpose is to ensure that workers select the appropriate size of non-woven masks for masks and wear them according to the correct process.
