In fact, it is possible, but there is a disadvantage that the breathing resistance is large and it is easy to break. Nowadays, some people in the market are not daring to accept pure nano-filtration membranes. Others are used to melt-blown fabrics. In this epidemic, many laymen came to produce melt-blown fabrics, which resulted in the stock of many low-filtration melt-blown fabrics. Another way to solve this inventory problem is to spin a layer of nano-membrane on the low-filtration melt-blown cloth, that is, nano-melt-blown cloth, which can process inefficient melt-blown cloth into 99.5% nano-melt-blown cloth. cloth.

The fiber pores of the nanofiber filter membrane are on the order of hundred nanometers (1/1000 of the diameter of the hair), which is two orders of magnitude smaller than the traditional meltblown cloth. It can directly intercept PM2.5. Under the same filter efficiency, the nanofiber membrane is thinner. , Bring lower air resistance; nanofiber does not need electrostatic electret technology, no charge loss, filtration efficiency attenuation and other issues, with more durable storage and service life. In the actual test, after the sample was machine washed 20 times and sterilized with alcohol for 50 times, the filtration efficiency almost did not decrease.

Songhu Shenjian Technology (Dongguan) Co., Ltd. relies on Songshan Lake Materials Laboratory, developed from the laboratory's new fiber team. The company is engaged in the research and development, production, sales, promotion and service of new material technology and its products.
