Information

There are three layers of medical masks, and the Melt-blown fabric is the middle layer. It has strong filtering, shielding, and heat insulation properties. It can sterilize and isolate viruses. It can be said to be the focus of a medical mask.

quality Melt-blown fabric

The inner and outer layers of medical masks are only supporting functions. The most important thing to filter viruses is the Melt-blown fabric in the middle. The filtration efficiency of ordinary Melt-blown fabric is 50%. It needs to be processed to increase electrostatic adsorption to achieve bacterial filtration above 99%. (BFE99 for short) Melt-blown fabric with 50% filtration efficiency can only be used as civilian protective masks, which can only prevent dust and dust, and cannot isolate viruses. However, all medical masks and surgical masks must use Melt with a filtration efficiency of 99%. -blown fabric.

In the chain of medical masks, Melt-blown fabric, special materials for melt blown cloth, and raw materials, special materials are the most important link. The main raw material for the production of special materials for Melt-blown fabric is Polypropylene. Fake Melt-blown fabric does not protect against viruses. Some fakes do not even reach the standard for electrostatic adsorption, so there is no effect of isolating viruses.
