1. Appearance of the KN95 nanofiber air filtration materials of mask
The KN95 nanofiber air filtration materials of mask have a flat appearance and suitable thickness.
2. Structure of KN95 nanofiber air filtration materials of mask
The KN95 nanofiber air filtration materials of mask were composed by non-woven fabric protective layer, nanofiber high-efficiency filter layer (core layer), melt-blown layer and skin-friendly non-woven fabric layer.
3. Property of KN95 nanofiber air filtration materials of mask
The filtration efficiency can be improved by increasing the thickness of the nano-fiber layer. Therefore, on the basis of KN90 nanofiber air filtration materials of mask, the thickness of the nanofiber layer was increased, and the prepared nanofiber air filtration materials of mask can meet the standard of KN95. The filtration efficiency for 0.3 μm non-oily particles at the flow rate of 85 L/min reaches to 95% (see the table below) , which can efficiently intercept fine particles such as spray, PM 2.5, dust, pollen and bacteria. The KN95 mask made by KN95 nanofiber air filtration materials of mask can be used for the protection of certain particulate matter, such as the dust generated from the process of grinding, cleaning and treating minerals, flour and certain other materials, it is also suitable for liquid or non-oily particles produced as a result of spraying, which do not produce harmful volatile gases.
The filtration resistance and filtration efficiency of KN95 nanofiber air filtration materials of mask (the results were obtained at a flow rate of 85 L/min and non-oily particles of 0.3 μm)
4. Direction for KN95 nanofiber air filtration materials of mask
The filtering effect of the nanofiber air filtration materials of mask developed by our company mainly depends on the physical interception effect of the nano-fiber layer, so the nano-fiber filter materials can be reused. Experimental data show that after 10 times of disinfection with boiling water or alcohol, the filtration efficiency of the nano-fiber filter materials for non-oily particles with a diameter of 0.3 μm can still be kept above 90% at a flow rate of 85 L/min, which can meet the protection requirements of the air filtration materials of mask.
5. Test report of KN95 nanofiber air filtration materials of mask
The nanofiber air filtration materials of mask manufactured by our company satisfy the KN95 protection standard. The results were obtained from the Henan Medical Device Inspection Institute.
