What's the difference between non-woven mask and medical mask for the defense of new coronavirus

Medical masks are divided into three layers: inner layer, middle layer and outer layer. The inner layer is skin friendly material (ordinary sanitary gauze or non-woven fabric), the middle layer is isolation filter layer (ultra-fine polypropylene fiber melt blown material layer), and the outer layer is special material bacteriostatic layer (non-woven fabric or ultra-thin polypropylene melt blown material layer).

With the use of non-woven fabrics and three-layer structure, can the respirator with dust-proof and moisture absorption have the same anti-virus effect as the medical respirator?

The answer is, of course, different.

What's the difference between a three-layer non-woven mask and a medical mask?

The answer is: processing technology. 1. Melt spray process 2, electrostatic electret process. The difference of using non-woven fabric is that using melt blown polypropylene non-woven fabric. Polypropylene non-woven fiber is very fine, can block bacteria and small particles. The electrostatic electret process is used to make the fiber easier to generate static electricity and absorb the substances with small diameter, so as to block the bacteria and viruses in the air.
