Effect of Hornbeam chips fungal pre-treatment on bleachability of its Bio-kraft pulp

Bio-kraft pulp made from Hornbeam chips fungal pre-treated (1, 2 and 3 weeks) was used for investigation of its bleachability by DED sequence. Before and after of each step in mentioned sequence, pulps and bleaching spent liquors characterized and then 60g/m2 standards handsheets made from above pul...
