Influenza virus test, infection capacity after 6 hours, 99% reduction

COVID-19: Komatsu Matere, Antivirus / Mask Inner: Decompose virus with new photocatalytic tech

Komatsu Matere:

Komatsu Matere has developed an antiviral mask inner using a new photocatalytic technology that oxidizes and decomposes viruses.

It has already begun production and will donate thousands of copies to a local hospital.

New photocatalytic technology: oxidative degradation of virus

Toshiba Materials cooperated technically and developed it over a year and a half.

Conventional technology:

A common photocatalyst uses titanium oxide.
However, the effect only appears in the ultraviolet region.
Therefore, it was difficult to obtain the effect in a dark place.

This new technology:

This new technology uses a special tungsten oxide,
With a wide range of light including the visible light region, the effect can be expected,
Decomposes virus in a short time even with weak light.

Actual evaluation: infection capacity / 99% reduction

Japan Textile Products Quality Technology Center / Influenza virus was used to conduct contact tests.

“The effect of reducing the infectivity by 99% after 6 hours at a brightness of 1000 lux (room level in the daytime)” was confirmed.

Komatsu Matere:

By combining tungsten oxide with a special adsorbent, we established a method to fix it on the fiber and established mass production processing technology.

Commercialized as a mask inner and donated to Komatsu Municipal Hospital.

In the future, using this technology

Hospital care materials,
mask,
Vehicle interior materials,
Interior related,
Expand to uniforms, etc.
