| Abstract: | Three kinds of cellulases with different components were applied to the deinking of mixed office waste paper, MOW. In the process of enzymatic deinking of MOW, not only improvement of toner particle removal was achieved with the addition of enzymes but other properties of the deinked pulps were influenced. Drainage properties of the deinked pulp were improved after treated with enzymes. Higher enzyme dosage was needed compared with that only for deinking purpose if obvious drainage improvement of the deinked pulp were to be achieved. The enzymatic hydrolysis of fibers did not lead to distinct fiber length decrease, but declined the zero tensile strength of the pulp declined with addition of enzymes, which indicating the decrease of individual fiber strength. In addition, enzyme treatment resulted in the enhancement of specific surface area of fibers. |
