Through the application of enzymes, the freeness of recycled pulps can be improved; however, with the improvements in freeness, there may also be a loss of strength. As enzyme effectiveness depends on the fiber degradation and fines content of the pulp, it also. depends on the amount of recycling that the pulp has undergone. To evaluate the relationships that exist between enzyme treatments and the number of recycles the fiber has undergone, a virgin CTMP was recycled three times. At each recycle enzymes were applied to the pulp. One leg of the experiment involved a repetitive enzyme treatment of the pulp, before each recycle. Freeness improvements were achieved at all levels of recycling. The single enzyme treatments were the most effectiv...
