There is a big problem with the quality of melt blown cloth for masks
       Conventional melt-blown cloths rely on their fibrous tissue voids to absorb particulate matter. Therefore, the filter needs to be increased in thickness to improve filtration efficiency. As the thickness of the filter increases, its respiratory resistance will also increase. In other words, wearing a qualified melt blown cloth mask will be very dull. Before the epidemic, the filtration efficiency of melt blown cloth masks reached more than 95%, and it was necessary to install a breathing valve to help avoid strong breathing. Now the melt blown cloth masks on the market are very thin and breathable. This is because the melt blown cloth produced now uses the process of injecting extremely static electricity. Relying on static electricity to absorb particles to achieve high efficiency and low resistance. In theory, electrostatic adsorption of particulate matter is feasible. The newly produced melt blown cloth has good data detected. The filtration efficiency can reach more than 99%, and the resistance can reach about 100Pa. However, static electricity has a fatal disadvantage, that is, static electricity will decay quickly.   
      There have been tests in the industry. When the melt blown cloth mask is opened and exposed to the air for 2 to 5 hours, its filtration efficiency will drop below the standard. When exposed to the air for about 40 days, the static electricity is lost. If stored in a high humidity and high temperature environment, the decay period will be shortened exponentially. Once the static electricity is lost, the mask will have no protective effect. This is also the real reason for a large number of unqualified returns of masks sold abroad during the epidemic.
      After the problem of electro-injection melt blown cloth was exposed, another kind of melt blown cloth called water-injection electrode appeared on the market recently. The process has been upgraded, but it is only a little bit stronger with extremely static electricity. The aging of its static electricity can only be extended to about three months. Some mask factories advertise that the validity period of water-injected polar melt blown cloth masks can reach two years. This is all bragging. Think about it, everyone, that is, high-energy storage batteries store enough energy, and within a year it will be lost.
