There are two kinds of non-woven masks, one is made of cotton absorbent gauze or knitted fabric, with various non-woven fabrics sandwiched in the middle; The other is directly made of non-woven fabrics. Now the new type is that the appearance and back are all non-woven materials, and a layer of filter paper will be sandwiched in the middle, so that the filtering effect of non-woven masks can be improved. What are the advantages of non-woven mask?
The reason why non-woven mask is loved by people is that it has the following advantages: good ventilation, non-woven fabric has better ventilation than other fabrics, and if there is filter paper in non-woven fabric, its filtration will be better; At the same time, the thermal insulation of non-woven mask is higher than that of ordinary mask, and its water absorption and waterproof effect are good; In addition, the non-woven mask has good retractility, even if it is stretched from left to right, it will not present a dishevelled phenomenon. It has a good handle and is very soft. Even if it is washed repeatedly, it will not become hard in the sun. The non-woven mask has great elasticity and can return to its original shape after long-term use.
However, it also has some defects: compared with other textile masks, non-woven masks have poor strength and durability, and are not easy to clean. If the usual care is improper, it is easy to tear.
Let's give a brief introduction to the broad users. Let's take a look at it together.
The filtration mechanism of non-woven mask only depends on the ultra-fine electrostatic fiber cloth, whose fiber diameter is about 1-5micron. Therefore, after the dust is captured by the ultra-fine electrostatic fiber cloth, it is not easy to be separated due to cleaning. Moreover, after the non-woven mask is washed with water, it will destroy the electrostatic dust collection ability. Therefore, the non-woven mask cannot be cleaned, and it cannot be used repeatedly, Therefore, it must be discarded after use.
Non woven mask is widely used in medical and health care, beauty, pharmaceutical, thermal insulation, good scalability, good air permeability, waterproof and water absorption. In particular, some pollutants in the air can be filtered by non-woven masks, and these harmful substances can be thoroughly filtered to ensure the well-being of everyone. However, the durability or strength of non-woven masks are relatively poor. Therefore, non-woven masks can not be cleaned and reused in washing. In addition, in the process of using non-woven masks, we must be careful. Its fibers are arranged in a certain direction, so it is easy to split from the right angle. I hope these aspects can arouse everyone's attention.
Many users will ask whether non-woven masks are anti-virus or not. The mask manufacturers will give a brief introduction to the broad users.
Good air permeability, non-woven fabric is better than other fabrics, if mixed with filter paper, it has better filtration; At the same time, the water absorption of the non-woven mask will reach the waterproof effect. Much better than gauze masks;
Non woven mask has good flexibility. Even if they stretch left and right, they don't look slovenly. They have a good feel, very soft. Even if they are washed many times, they don't harden in the sun. The non-woven fabric mask has elasticity and can be restored after long application.
As for antiviral and antibacterial infection, it is suggested to choose medical masks. In addition to the high health requirements for medical masks, medical protective masks also have the function of effectively preventing liquid splashing. Due to the possibility of blood or infectious body fluid splashing during the operation, this kind of splashing has a certain pressure, rather than ordinary liquid penetration, and the mask data has a relatively high ability to block the pressurized liquid. Only in this way can it work. Antiviral pathogens. Therefore, in the specification of medical protective masks, special testing methods are used to test the barrier properties of these products.
