How do anti-virus and waterproof surgical gowns achieve efficient protection with multi-layer microfiber filtration layers?

The multi-layer microfiber filtration layer design of anti-virus and waterproof surgical gowns is the core of their protective performance. This design is inspired by in-depth research and imitation of the filtration mechanism in nature. The outermost layer is usually composed of coarser fibers, which can effectively block larger particles and liquids, such as blood and body fluids. The design of this layer is mainly to reduce the risk of liquid penetration while keeping the surgical gown clean and hygienic.

As the filter layer goes deeper into the inner layer, the diameter of the fiber gradually decreases and the filtration level gradually increases. This gradual transition design not only improves the overall filtration efficiency, but also ensures the breathability and comfort of the surgical gown. The diameter of the inner fiber can reach the micron level or even the nanometer level. These tiny fibers can be closely arranged to form an almost impeccable barrier to block extremely small virus particles, bacteria and other microorganisms in the air.

Among the multi-layer microfiber filtration layers, the nano-level filtration layer is undoubtedly the most critical link. The nano-scale filter layer is usually made of nanofibers, which are only tens to hundreds of nanometers in diameter, much smaller than the size of virus particles. Therefore, when virus particles in the air come into contact with the nano-scale filter layer, they are tightly ""captured"" by the fibers and cannot penetrate the surgical gown.

The excellent performance of the nano-scale filter layer is not only reflected in its high filtration efficiency, but also in its good air permeability and durability. Since the diameter of the nanofibers is extremely small, the gaps between them are also very small, which allows air molecules to pass smoothly while blocking virus particles. This design not only ensures the breathability of the surgical gown, but also ensures that medical staff can remain comfortable after wearing it for a long time.

In addition, the nano-scale filter layer also has good durability. Because the nanofibers are arranged tightly and orderly, they can withstand greater tension and pressure and are not easily damaged. This allows the surgical gown to maintain its protective performance after multiple washing and disinfection, extending its service life.

In practical applications, the design of multi-layer microfiber filter layers brings many advantages to anti-virus and waterproof surgical gowns. It can effectively block virus particles, bacteria and other microorganisms in the air, providing medical staff with all-round respiratory protection. This feature is particularly important during the epidemic, which greatly reduces the risk of medical staff being infected by contact with the virus.

The design of the multi-layer microfiber filter layer also improves the durability and breathability of the surgical gown. This allows medical staff to remain comfortable and dry after wearing it for a long time, and will not affect their work efficiency due to stuffiness or discomfort. At the same time, the durability of the surgical gown also ensures that it can still maintain its protective performance after multiple washing and disinfection, reducing the operating costs of medical institutions.

The design of the multi-layer microfiber filter layer also brings good waterproof performance to the surgical gown. Because the outermost coarse fiber can effectively block liquid penetration, the surgical gown can still remain clean and hygienic when it comes into contact with blood, body fluids and other liquids. This feature is particularly important during surgery, which reduces the risk of cross infection and improves the safety and efficiency of surgery.
