• After drying naturally, it is grilled with a lighter.

The tissue only carbonized and did not ignite. It has been proven not to spread.

I have been in contact with the flame for a longer time in the video below.

The texture was a bit difficult, but when it was re-produced at a later date and the tissue was squeezed, the texture became soft.

In addition, it did not ignite even when it was torn and fluffed.

It is thought that flame retardancy can be maintained for paper such as tissue even if the density is reduced or the amount of coating is reduced.
