Flame resisting-ization of hempen string, processing

After gan infringement promoted hempen string (numbness) to soufa for about about 30 seconds, I squeezed and made them dry naturally solidly.

I’m igniting in an alcohol lamp. Oneself doesn’t ignite basically and even if he ignites a little, extinguishes a fire.
Smoldering seems to be left during restriction, but I can think increase getting thin settles ganshinryou in soufa.

It could be proved that flame resisting-ization of a jute bag and prevention flame-ization were also possible by this.
