Abstract

This paper reported an improved computational model of pyrolysis of cotton fabric that exposed to a constant radiant heat flux. Shrinkage occurring in the char layer during the pyrolysis reactions was incorporated into the proposed detailed model. At present, gas phase oxidation reactions are not included and the model will be validated at next stage. The method for modeling will help contribute to a better understanding of the ignition mechanism of flame-resistant cotton fabrics used for fire safety garments.
