Everything you need to know about Venus N95 Mask

March 15, 2021

Out of 111 million population affected by COVID, globally, 28.1 million cases are from the US alone, as of 22 of February 2020. With the rising number of COVID cases, the usage of effective masks has become imperative. While the year 2020 was eclipsed by a coronavirus, the year 2021 has come under the attack of a new mutant strain, B.1.1.7 which is 70% more contagious than SARS-CoV2. Therefore, it is advisable not to let the guard down even if the lockdown is over and follow the COVID norms by maintaining social distance, washing hands, and wearing masks. And not just any mask but wearing effective ones is what will get you through these troubling times

As per Mayo Clinic, N95 masks are far more effective than regular masks and medical masks because they prevent large and small particles from passing through. Due to the higher efficiency of these masks to prevent the transmission of coronavirus the research is going to turn these disposable masks into durable to reuse them. The National Institute of occupational safety and health (NIOSH) is the regulatory body that certifies the quality and effectiveness of N95 masks. Apart from N95 face masks, N95 respirators are available in the market which is approved by U.S. Food and drug administration (FDA) and NIOSH for better filtration and fluid resistance.

What is N95 mask

N in the N95 masks means non-oil which means that the masks are highly recommended to use in a setting that is free of oil particles. Likewise, in some other masks means they are resistant to oil to some extent whereas means it is oil-proof. Whereas, 95 stands for efficiency percentage which means that N95 masks filter out 95% of particles above 0.3 microns, efficient in protecting against airborne particles, however not oil-resistant.


How are N95 masks produced

The masks are made from mesh-like layers of non-woven polypropylene fabric. The first two coatings of the masks facing outside and inside are spun-bond. In the process of spun-bonding, nozzles are used to create a piece of fabric by blowing melted threads of polypropylene. These threads are anywhere between 15-35 micrometers which are blown through the nozzle on the conveyor belt. This raw mesh then goes through a thermal, mechanical, and chemical treatment to form a stronger bond. The first two coatings on the outside of the mask are somewhere between 20 and 50 g/m2 thick which is the 1st line of defense against the contaminants.

Another needled nonwoven pre-filtration layer of 250 g/m2 thickness is added along with a filtration layer. This pre-filtration material passes through the barbed needles to strongly bond the layers together. The next process that this pre-filtration layer goes through is a calendering process to thermally bond the fabric using specialized rolls. Then the final layer is made from melt-blown electret nonwoven material. The process of melt-blown uses the nozzles to air spray the threads of melted synthetic polymers on the conveyor belt. These threads begin to cool off and bond along the conveyor belt and turn into fabric. After this stage, sometimes the material goes through thermal bonding to make it stronger. The final stage of developing a mask from this fabric is achieved by using a converting machine that helps join these layers together using ultrasonic welding. It is at this stage that the straps are attached and the shape of the mask is formed which can snugly fit. And the masks are ready for distribution but not before serialization.
