Degradation mechanisms of fibre polymers It has been established that cellulose is very sensitive to mild heat, electron beam and mechanical treatment, and that the DP decreases via a second-order relationship with time of heating. Oxygen-initiated formation of hydrogen oxygen and polymeric radicals causes depolymerisation, random degradation and yellowing. It has been found that cellulose
