| Abstract:In this paper, in order to find a feasible way to enhance the preimpregnation effectively, the effect of penetrant application in preimpregnating stage of CTMP process was studied. It was found that, compared to the control sample, the sample with using penetrant has longer mean length of CTMP fiber, and the fiber length distribution is more concentrated to a region with longer length value. The shives and fines are decreased significantly, while the whiteness, bulk, tensile index and tear index are improved in various degrees with a lower refining energy consumption. |
