Kynol is composed of only C (carbon), H (hydrogen) and O (oxygen).
Therefore, it does not contain any phosphorus or nitrogen elements which cause toxic gases when burned. It does not contain nitrogen.
In addition, it produces less smoke than organic and natural fibers.
Kynol has high flame resistant characteristics, does not melt even at high temperatures, and has little heat shrinkage. In addition, it is called a highly safe fiber because it only carbonizes and emits a small amount of smoke when it is exposed to flame.
