Influences of Laccase Mediator System on Bleachability and Fiber Properties of APMP Pulp

Abstract:

In this research, the laccase mediator system (LMS) was used to modify the unbleached triploid populus tomentosa alkaline hydrogen peroxide pulp (APMP). The changes of pulp brightness were measured and the effects of LMS on the subsequent hydrogen peroxide bleaching were also determined. Besides, the fiber morphology was analyzed by ESEM, and then the obvious changes of pulp have been recovered. In a word, the LMS has obvious effect on cellulose.
