Chinese Wholesale 100% Polypropylene Make-to-order Printed PP Spunbond Non Woven Fabric for Mask
The dust blocking efficiency of a mask is based on its blocking efficiency for fine dust, especially for respirable dust below 2.5 microns. Because dust of this particle size can directly enter the alveoli, it has the greatest impact on human health. Gauze masks, the principle of dust blocking is mechanical filtration, that is, when dust hits the gauze, through layers of barriers, some large particles of dust are blocked in the sand cloth. For some fine dust, especially dust less than 2.5 microns, it will pass through the mesh of the gauze and enter the respiratory system. Dust-proof masks are composed of activated carbon fiber mats or non-woven fabrics as filter materials. Respirable dusts smaller than 2.5 microns are blocked during the process of passing through this filter material and play a role in filtering the air.
