The nanocoating technology of Delaware-registered US company XTI is believed to be the first in the world to achieve an antibacterial efficacy rate of 100%.

The company’s Active-Shield fabric has been verified 100% effective against dangerous E.coli and MRSA (S.aureus) bacteria by leading testing and certification company SGS, based on the standardized AATCC100 test by the American Association of Textile Chemists and Colorists.

The company already markets a facemask based on three-layer nonwovens and proven to be 99.999 % effective against bacteria.
