What Are The Important Materials for Face Masks
With the outbreak of the Covid-19, he production and sales of masks have increased substantially worldwide. Masks can prevent the spread of droplets and prevent the invasion of bacteria and viruses, which are an important means of protection.
The masks that can play a role in virus protection are mainly medical surgical masks and N95 masks. The regulation for bacterial filtration efficiency of surgical masks is: under specified conditions, the filtration efficiency of Staphylococcus aureus aerosol with an average particle diameter of (3 ± 0.3) ㎛ is not less than 95%.
That’s also the origin of the concept of N95. Therefore, although the N95 mask is not a medical mask, it meets the standard of filtering efficiency of 95%, and can better fit the human face, so it can also play a good role in virus prevention.
In order to achieve good protection, two materials are important: melt-blown non-woven fabric and nose bridge strip. Meltblown fabric is the core material of the mask. The diameter of the virus is about 1-10 microns, while ordinary medical masks can resist particles above 3 microns, and the melt-blown isolation layer can effectively isolate most viruses.
Due to the protrusion of the nose, no matter whether the face mask is thick or thin, it cannot completely fit with the face. Without aluminum nose wire, outside air with germs and other harmful substances enter the nasal cavity through the both sides of the nose bridge, therefore the aluminum nose strip plays the role of supporting the mask to fit the nose bridge.
If you are the manufacturer of face masks or aluminum nose wire, Haomei Aluminum can offer you aluminum nose strip for face mask. Its specification is shown below:
1. Aluminum alloy: 1060 and 3003
