The wet strength unbleached paper displays after heat treatment is examined in this thesis in which the authors examine the underlying mechanisms of this phenomena by experiments on differently treated paper. Two wet strength mechanism theories are examined; Lignin working as a resin versus carbonyl bonds being the main driving force behind the wet strength after thermal treatment. The authors find that using oxygen bleaching does not increase the wet strength as it would if carbonyl bonds were the main wet strength drivers, the results thus point towards the resin theory but further corroboration is needed before inference can be drawn.
