Zetta, a startup company spun off from Tokyo Institute of Technology in Japan, has developed a non-woven nano-fiber material that will not be affected even after 100 hand-washes with a detergent. The company is planning to use this material to produce masks
Z-Mask masks can filter particles smaller than 0.1 microns and 0.3 microns smaller than N95 masks
Zetta will produce and sell "filter elements" that can be added to cloth masks. It will also cooperate with a manufacturer to produce masks for medical personnel and higher protection capabilities.
Zetta participated in a plan of the Japanese government to provide necessary protective materials to medical workers and other susceptible people in New Crown. Zetta will commercially produce its nonwoven nanofibers called Z-Mask.
N95 masks can filter at least 95% of airborne particles and protect particles as small as 0.3 microns. The diameter of the N95 mask material fibers is between 3 and 5 microns. The diameter of the Z-Mask fiber is 0.08 to 0.4 microns (one millionth of a meter), which is less than one tenth of the fiber of the N95 mask material.
Using intermolecular interaction forces including molecular gravity, Z-Mask can block particles smaller than 0.1 microns, such as the new coronavirus.
