How do I identify the authenticity of the mask?

Published on 2020/7/6

In the face of the "mask shortage", fake masks are also appearing in large numbers on the market. Experts reminded that they can be identified by the following methods.

It can be judged by two methods:

Cut open the mask and observe the middle layer. The meltblown cloth is located in the middle layer of the disposable face mask, its structure is dense and white. while the spunbond fabric structure is relatively loose and has high transparency. while the spinning fabric structure is relatively loose and has high eras. In addition, the strength of meltblown cloth is very low, and it breaks when it is pulled by hand; the strength of spunbond cloth is higher, and it needs a lot of force to tear.

The appearance is observed directly. Melt blown cloth has a dense structure and almost impermeable; many fake and inferior masks that without melting melt blown cloth have high light transmittance and the facial skin is faintly visible when worn.

Whether it has static electricity.

In order to make breathing as smooth as possible and while meeting the protection requirements, qualified 3 ply face masks with meltblown cloth  will go through an "electret process." The surface of the fiber after the electret has a large amount of electric charge, which intercepts fine particles by electrostatic adsorption effect.Therefore, it will have obvious attraction to hair, iron filings, etc. Although the amount of meltspray cloth in a single mask is small and the effect of adsorbing hair is not obvious, the existence of electric  charge can also make it adsorbed on the wall.

Some of the fake masks, although there is a melting spray cloth, but did not go through the pole, Or because the technology is not up to standard, storage time too long and other reasons lead to a large number of dissipation of charge, and their protective performance will naturally not meet the standard.
