The thermal behaviour of a blend of cotton and fire-retardant polyester fibres: A kinetic study

This work compares the thermo-oxidative degradation of cotton and fire-retardant polyester fibre (PESFR) fabrics and that of a cotton/PESFR blend, The association in a blend of PESFR with cotton fibres improves the burning behaviour of the latter, The invariant-kinetic-parameter (IKP) method allows one to modelise the degradation of the material, and in particular to compute the degradation velocity. We demonstrate that the 'fuel-flow' rates give rise to the fire retardancy of the materials and that the latter, in this case, does not depend on the nature of the gases evolved.
