Types of non-woven masks
There are two types of non-woven masks as respiratory protective equipment. One is made of absorbent gauze or knitted fabric with pure cotton on the surface, with various non-woven fabrics in between; the other is directly made of Made of non-woven fabric. Now the new non-woven masks are made of non-woven materials on the surface and back, with a layer of filter paper in between, so that the filtering effect of the non-woven masks can be improved. 
Advantages of non-woven masks
1. Good air permeability, non-woven fabric has better air permeability than other fabrics, and if filter paper is mixed in the non-woven fabric, its filterability will be better; at the same time, the water absorption and waterproof effect of the non-woven fabric mask Much better than gauze masks;
2. The non-woven mask has good elasticity, even if it is stretched left and right, it will not appear messy. It has a good hand feel and is very soft. Even if it is washed many times, it will not harden under the sun. Non-woven masks are highly elastic and can return to their original shape after long-term use.


Disadvantages of non-woven masks
Compared with other types of masks, non-woven masks have poor strength and durability, and they cannot be washed. If they are used improperly, they are prone to tearing. Secondly, the protection level of non-woven masks is low. After all, the material production process is relatively basic. In the event of an epidemic or haze weather, non-woven masks basically cannot protect.
Use crowd
Non-woven masks are used more in workshops. Ordinary people buy them when they are not fighting the virus. Medical masks are mainly used by medical personnel (under normal circumstances).
It can be seen that non-woven masks only have the ability to prevent dust, but they do not have the ability to prevent viruses. Therefore, wearing non-woven masks cannot prevent viruses. If you want to prevent the virus, you still need to wear a disposable medical mask, which can help people prevent 70% of the virus.
