Why Can 3M Mask N95 Stop The Spread Of the Virus?
3Mask N95 Respirator Mask offer great protection as its raw materials are all polypropylene (PP for short). The mask for medical use is generally multi-layer structure, generally referred to as SMS structure.,
but with the addition of the Cool air filter Exhalation Valve for extra comfort! These N95 masks are a high quality 3M mask featuring lightweight construction for greater worker comfort and increased wear time. The n95 mask has a cushioned, adjustable nose clip that helps provide a custom fit and secure seal. Made in USA.
What material is N95/KN95 Respirator Mask made of?
we often say that several layers of masks, in the national standard of masks GB / T 32610 does not stipulate that if it is a medical mask, it should be at least three layers, that is, SMS (two layers of S and one layer of M). At present, the highest number of layers is five layers, that is, smmms (two layers of S and three layers of M). It is not difficult to make a mask, but it is more difficult to make smmms cloth.
In this case, S represents spunbond, whose fiber diameter is relatively thick, about 20 microns (μ m). The main function of two layers of S spunbond is to support the entire non-woven fabric structure, which has little effect on barrier.
The most important part of the mask is the barrier layer or melt blown layer M (meltblown). The fiber diameter of the melt blown layer is relatively small, about 2 microns (μ m), so it is only one tenth of the diameter of the spunbond layer, which is very important to prevent bacteria and blood from penetrating.
3M Mask is a good choice
3M’s brand impression has long been there. When SARS happened in 2003, the professional N95 respirator Mask and protective clothing worn in the hospital were 3M’s. In fact, 3M water is also used for disinfection in hospitals
