Non-woven masks are not anti-virus. Non-woven masks are a common type of protective masks made of non-woven raw materials. They can actually only block a part of dust and large-diameter fine particles, but they have little effect on blocking virus, PM2.5 and other small particles. If there are viruses and germs in the environment, Labor Insurance Network suggests to buy N95 protective masks or professional gas masks for self-protection. Types of non-woven masks There are two types of non-woven masks as respiratory protective equipment. One is made of pure cotton skim gauze or knitted fabric, and various non-woven fabrics are sandwiched in the middle; the other Classes are directly made of non-woven fabrics. Now the new non-woven masks are made of non-woven materials on the surface and the back, with a layer of filter paper in between, so that the filtering efficiency of the non-woven masks can be improved. Advantages of non-woven masks 1. Good air permeability, non-woven fabrics have better air permeability than other fabrics, and if filter paper is mixed in the non-woven fabrics, its filterability will be better; at the same time, the non-woven masks absorb water The performance and waterproof effect are much better than gauze masks; 2, non-woven masks have good elasticity, and they will not appear unkempt even if they are stretched left and right. They feel good and are very soft. Even if they are cleaned many times, they are in the sun It will not harden even if it is irradiated. Non-woven masks are highly elastic and can return to their original shape after long-term use. The disadvantages of non-woven masks Compared with other types of protective 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 raw material production process is relatively basic. In the event of an epidemic or haze weather, non-woven masks basically cannot protect. Which kind of protective copper mask
can prevent viruses? is suitable for anti-virus. It is recommended to choose medical masks to prevent bacterial infection. In addition to higher hygiene requirements, medical protective masks also have the function of effectively isolating liquid splashes. In view of the probability of blood or infectious body fluid splashing during the operation, this splash has a certain pressure and is not a normal liquid infiltration. The raw materials of the protective copper mask have a relatively high ability to isolate the pressured liquid, and this is the only way. It can effectively prevent viruses and germs. Therefore, in the standard of medical protective masks, special inspection methods are selected to test the performance of the barrier liquid of such products. The above is the introduction provided by the editor of the labor insurance network about whether non-woven masks can prevent viruses. I hope it will be helpful for you to understand non-woven masks! After the use of non-woven masks, a lot of dust, germs and other pollution will accumulate on the outer layer Therefore, non-woven masks cannot be used alternately on both sides to avoid cross-infection. 213
