a. Cut Off the Face Masks and Observe The Middle Layer.

 

The melt blown fabric is located in the middle layer of the face masks, and its structure is dense and white, while the spunbonded fabric is relatively loose.

The melt blown fabric has low strength and can be torn by hand; the spunbonded fabric has high strength and requires a lot of force to tear.

 

b. Appearance Observation.

The structure of melt blown cloth is dense and almost opaque, and the fake and inferior masks without meltblown cloth have higher transmittance.

3. Whether the Meltblown Nonwoven Fabric has Static Electricity.

 

The qualified melt blown cloth for mask will go through the "electret process" to intercept fine particles through electrostatic adsorption effect, so it will produce obvious attraction to hair, iron filings, etc.

Although some fake and inferior face masks have Meltblown Nonwoven Fabric, they have not passed the electret, or because of poor technology and long storage time, the electric charge dissipates greatly, and its protective performance is not up to standard.
