Antiviral fabric face mask

A typical face mask made of polymer base fibres can be only used for a few hours. These masks usually suffer from the accumulation of bacteria and viruses.

How does antiviral face mask work?

According to the recent reports by Japanese researchers, the fabric face mask has shown the best performance against the outbreak of coronavirus. The simulation conducted by Japan’s Fugaku centre, which is one of the largest supercomputer systems in the world, showed that disposable and fabric masks do not allow the infiltration of airborne droplets while the performance of fabric mask is 80% better than a disposable mask.

The technology silver and natural fibre used in this mask improve the signs of efficiency also can reduce the life of the virus and destroy them.

The silver fibre in mask decompose of virus shell in a short time (less than 5 minutes), so the activity of virus become disrupted and if it enters in the body couldn’t replication.

In the past time, silver has been used in medicine, which has effects such as fighting disease and accelerating the recovery of the patient. Silver can kill 650 types of bacteria, fungal and viral contaminant and can be used as a very strong disinfectant.

The weakness of ordinary masks with artificial fibres

  • They are disposable.
  • They have difficulty breathing.
  • They are not able to kill viruses, bacteria and other infections.
  • After a few hours, these masks become the main cause of the accumulation of viruses and bacteria.

FINSHIELD Fabric Face Mask

The Finpers fabric made of cotton and silver fibres. According to experiments conducted in the United States and Japan, silver fibres greatly increase the performance of cotton fibres and eliminate all contaminated particles in the air and air, such as bacteria, germs, fungi and viruses, as well as coronavirus activity above 99% Disrupts.
As can be seen in the picture below, the intertwined silver metal fibres create a strong shield against viruses and bacteria, and the density of these fibres eliminates bacterial, viral and microbial contaminants, and after washing the mask, it becomes uninfected again. Many airlines around the world use silver for antiseptic and disinfectant for cabin air.

Fin Shield Anti-Viral Fabric Properties

  • Strong antimicrobial efficacy demonstrated by ISO 18184 tests.
  • Antimicrobial properties are built-in to protect the product. Always clean the product thoroughly after each use.
  • It can be used for clothing, home textiles and accessories such as face masks and gloves to make them extra resistant against degradation by microorganisms
  • For washable fabrics: the treatment is effective for at least 100 washes at 140°F
  • Residual virus infectivity tested according to a modified ISO 18184 method, a rapid antiviral effect demonstrated within 5-10 minutes 
  • Tested according to EN-14476 as a strong antiviral against enveloped on Adenovirus and Polioviruses 
  • Effective against microorganisms

Textiles can provide a hosting surface for microorganisms and therefore need an antimicrobial technology to stay cleaner and usable for longer.

FinShield uses advanced silver technology. It is designed to inhibit the growth of microorganisms and their odours on textile surfaces.

A potential host for microorganisms – Textiles

Textiles provide us with the most basic protection to our bodies, ensuring comfort and well-being. But they also provide a large hosting surface for all kinds of microorganisms, some of them are problematic for an extended utilization of the textiles, and these microorganisms can live for days to months on textiles and multiply rapidly!

Feel clean and confident with enhanced preservation of your clothes, enjoy a relaxing time on your fabric sofa and sleep soundly in your bed. Fin Shield guards the textiles against the growth and action of microorganisms and its degradation and odours. Antimicrobial properties built-in to protect the product. The product does not protect users or others against bacteria, viruses, germs or other disease organisms.
