Dependence of the combustibility of fibres on their degree of pyrolysis and carbonization
- 19 Downloads
The combustibility characteristics of pyrolyzed and carbonized viscose and polyacrylonitrile fibres have been investigated: oxygen index, limiting oxygen concentration, autoignition temperature, and glow point.
It has been shown that the combustibility of pyrolyzed and carbonized fibres prepared from polyacrylonitrile is somewhat lower than the combustibility of those made from viscose fibres: this is connected with a more perfect aromatic structure and with the presence of nitrogen atoms in the first and of oxygen atoms in the second.
