PPE
Three-ply (three layers) mask
Three-ply (three layers) mask made by high quality melt-blown material, which has excellent bacteria filtration and air permeability while remaining less slippery than woven cloth.
We are provide difference filtration level of mask in each type .
Disposable Mask
N95 (ffp2, ffp3)
An N95 mask or N95 respirator is a particulate respirator with a filter that meets the N95 NIOSH air filtration rating, meaning that it filters at least 95% of airborne particles but is not resistant to oil. It is the most common particulate filtering facepiece respirator. This kind of respirator protects against particulates, but not gases or vapors.
N95 respirators are considered functionally equivalent to certain respirators regulated under different jurisdictions, such as FFP2 respirators of the European Union and KN95 respirators of China. However, slightly different criteria are used to certify their performance, such as the filter efficiency, test agent and flow rate, and permissible pressure drop.
The N95 mask requires a fine mesh of synthetic polymer fibers produced through a highly specialized process called melt blowing that forms the inner filtration layer that filters out hazardous particles.
Melt-Blown
The melt blown process is a nonwoven manufacturing system involving direct conversion of a polymer into continuous filaments, integrated with the conversion of the filaments into a random laid nonwoven fabric. First developments in this field of technology in the industrial area started around 1945.
Melt blowing is a conventional fabrication method of micro- and nanofibers where a polymer melt is extruded through small nozzles surrounded by high speed blowing gas. The randomly deposited fibers form a nonwoven sheet product applicable for filtration, sorbents, apparels and drug delivery systems.
In different level of filtration mask, its using different of Melt Brow. usually is separate to BFE 99, BFE 98 , BFE 95, BFE 91 etc.
Mask as N95, N99, N100 Melt-blown The commonly used weight is 30g/sm-60g/sm. and can meet US standard NIOSH 42 CFR 84. Face Masks made of N95, N99 N100 pp melt-blown nonwoven fabric can effectively block the spread of bacteria.
Our surgical mask Melt-blown used weight is 25g/sm, BFE99
Our medical and insolation mask Melt-blown used weight is 20/sm, BFE98
