It’s been four months that lockdown was imposed all over India. Nevertheless, the constant surge of information regarding the new coronavirus enclosing the people in a worldwide pandemic continues to change. Numerous states across the U.S, Australia, and more counties report that attempts to "level the curve" is working. However, scientists continue to warn that people worldwide must be prepared for COVID-19 associated impacts until 2021. At the same time, several government leaders have displayed a vigilant optimism for the summer. Notwithstanding other uncertainties, the CDC keeps on recommending that everyone put on cloth face masks in public. The CDC states that healthcare workers must wear N95’s and surgical masks.

All Fabrics Aren’t As Effective In Filtering Out Airborne Particles

The CDC also states that all fabrics aren’t created equal in filtering out airborne particles. A new study has come out in the journal called ACS Nano. What does it advise as to the most efficient mask? A blend of cotton and chiffon or natural silk. Several companies are making affordable Cotton face masks for the common people.

The Explanation Behind The Present Social Distancing Norm

What happens when an individual who has virus coughs or sneezes? Infected particles are ejected into the atmosphere. Saliva droplets are fairly large and vary in size between one and five millimeters. They travel in a circle of some six feet from the infected person. This fact is the reason for the present social norm of keeping such a distance from other people in public. Making contact with the virus-infected droplets spreads the disease. However, the droplets that disband into the atmosphere and stay suspended for long also raise concerns.

These particles are known as aerosols. They are capable of traveling several hundred meters in the air. Moreover, aerosols that have a size of 10 nanometers to 10 micrometers are respirable. People can breathe them into their lungs. Thus the importance of having a mask on over one’s mouth and nose. The mask thwarts the inhalation of particles having the virus and is crucial to thwarting infection.

Which Fabric Is The Best For Face Masks?

At the University of Chicago, scientists tested out various fabrics that include cotton, polyester, flannel, natural and synthetic silk, and chiffon. What did they do for testing the filtration effectiveness of every one of these fabrics? First, they deployed a fan for blowing aerosol having particles sized between 10 nanometers and six micrometers across the above cloth samples. The fan blew the aerosol at a resting respiration frequency. Next, they measured the dimension and the number of particles that remained in the atmosphere after the aerosol passed through the fabrics. They compared these figures with the figures before blowing aerosol across the cloth samples. The conclusion was that Cotton face masks with some chiffon or natural silk were the best.

Face masks that have double-layered pure organic cotton are the most prevalent today. Health organizations recommend them the most. A number of companies and voluntary organizations continue to make them. People can keep themselves and their family members safe throughout the Covid-19 epidemic by wearing these masks.
