Non-woven masks are best for preventing new coronavirus

  • Release on:2021-03-31
Masks made of non-woven fabrics are more effective than other common masks in preventing the spread of Covid-19 through air droplets.

According to the Nikkei Asian Review, Fugaku can perform more than 415 trillion calculations per second. It simulated the effectiveness of three types of masks to prevent viruses and found that non-woven masks are better than those made of cotton and polyester. Masks are better at stopping the aerosol sprayed out when the wearer coughs.

Non-woven masks(Nonwoven Face Mask On Sales) are disposable medical masks that Japanese people often wear during the flu season and the new crown virus pandemic. They are made of polypropylene and are relatively cheap to produce in large quantities.

Non-woven fabric has no warp and weft threads, it is a fabric that does not need to be spun and weaves. It just aligns or randomly arranges short textile fibers or filaments to form a web structure, and then uses mechanical, thermal bonding or chemical methods. Reinforced.

Because it is not interwoven and knitted together by yarns one by one, but the fibers are directly bonded together by physical methods, it is impossible to draw out the thread like ordinary clothes.

Textile masks, including those used in Fugaku simulations, are usually made of fabrics such as cotton. After a temporary shortage of non-woven masks(Earloop Face Mask Company) in some countries, textile masks appeared.

They can be reused and are usually more breathable, but according to the World Health Organization (WHO), they should be cleaned with soap or detergent and water at least 60 degrees Celsius at least once a day.

According to experts from the Japanese Institute of Physics and Chemistry (Riken), this kind of non-woven fabric can block almost all water droplets from coughing. The Institute of Physics and Chemistry is a government-supported research institution in the western city of Kobe in Japan.

Cotton masks and polyester masks are slightly less effective, but they can still block at least 80% of droplets.

According to computer models, non-woven "surgical" masks(Surgical Mask Vendor) are slightly less effective at blocking small droplets below 20 microns, and more than 10% of the droplets will leak from the gap between the edge of the mask and the face.

A micrometer is one millionth of a meter.

Makoto Tsubokura, a research team leader at the Computing Science Center of the Japan Institute of Physics and Chemistry, encouraged people to wear masks even when the heat wave swept through most parts of Japan.

According to the Nikkei, Tsubokura said: "The most dangerous thing is not to wear a mask."

"It's important to wear a mask, even cloth masks that are less effective."
