As we all know, a qualified disposable face mask is composed of three layers. The outer layer is non-woven fabric, the inner layer is skin-friendly non-woven fabric, and the middle layer must be filter paper (melt-blown material) with great filtering effect.
The filter paper in the middle of the mask is made of melt-blown material, and different quality of melt-blown material has different filtering effects. If a mask wants to meet a certain standard, it must achieve a certain filtering effect.
There are many shoddy non-woven disposable face masks on the market that actually use fake melt-blown material. To judge the authenticity of the melt-blown material, there are the following methods to verify:
1. High-quality melt-blown cloth has electrostatic adsorption effect, which can easily absorb fine dust through electrostatic action, effectively blocking pathogenic microorganisms, particulate matter, etc.
2. The real high-quality melt-blown cloth is not flammable and has no black smoke. The fake melt-blown cloth burns easily.
