摘要
Hydrogen peroxide constitutes a bleaching agent well adapted to the treatment of pulp previously delignified by organic peroxyacids. Such bleached pulp presents, in an unexpected way, mechanical properties superior to those of unbleached (raw) pulp and to those of pulp treated by peroxyacids. This phenomenon is attributed to the effect of soda neutralisation of cellulosic fibres hydration, and hydrolysis of the ester functions formed during organic acid pulping. The regeneration of hydroxyl functions without cellulose chain degradation leads, by increasing the number of hydrogen bonds formed between the cellulose chains, to improved pulp mechanical properties and is of great interest for further industrial development.
