Japan is famous for its technology and innovation. Of course, it would be a shame if we forgot about innovation in Japan's textile industry. Everybody has heard about Uniqlo Heattech or Airism UV cut, but those are not all of Japan's functional fabrics. Every season, manufacturers all over Japan come up with newer and more amazing textile technology. Since there is so little information in English about these on the internet, in this series, I will guide you through a list of famous functional fabrics in Japan.
As the demand for masks increases, hygienic functional materials and antibacterial material for cloth masks are attracting attention. Beside the shining star Cleanze® , there is a fabric called CatLight® that also matches every criterion for making cloth masks.
Catlight ® is a photocatalyst coating fabric created by integrating Tokai Senko's original technology and V-CAT ® technology of Toyota Central R & D Labs., Inc. With this technology, Catlight fabric is able to respond to the light of the environment.

In the photocatalytic process, Catlight fabric is able to:
Catlight® technology is effective in UV rays as well as in fluorescent lights. Since this photocatalyst uses nano-level fine particles, it does not affect the texture of the fabric.
Of course this is what we are all waiting for. The actual effectiveness of Catlight fabric when used as mask material.
Catlight is suitable for use as the outer layer because of its photocatalytic properties. Since it decomposes dirt and deodorizes, it has an antibacterial function and is extremely hygienic. Moreover, Catlight fabric can be washed and reused, so you don't have to worry about Catlight losing its characteristics.
One thing to note is that Catlight is not an antiviral finish fabric, therefore it is recommended for use as an outer layer of the mask instead of the inner layer, which the fabric directly touches the mouth.
Let's take a look at the Catlight fabrics list, shall we?

Cloth masks are said to be less effective than traditional medical masks when it comes to preventing virus transmission. However, in terms of cost-effectiveness and being environmentally friendly, I still prefer traditional cloth masks over one-time-use masks. Photocatalyst coating fabric is incredible, but there are more textile innovations that I can't wait to share. What is your favorite functional fabric that you discovered recently?
