Theory 076/Textiles & Fibres
Flammability Is a Char Ratio
The claim
Textile flammability is set by the ratio of char-forming to fuel-forming decomposition pathways rather than by ignition temperature.
01The mechanism
Char insulates and slows pyrolysis; the branching ratio between pathways determines whether the fabric self-extinguishes.
02Predictions
- P1Flammability should track the ratio.
- P2Higher ignition temperature should not guarantee safety.
03Refutation
Flammability tracking ignition temperature would remove the pathway ratio.
