| Abstract | Fractionation is a technique, which is already in practice in some packaging mill. It is always suggested as one of option to enrich the quality of end-product and better processing of the raw materials. Due to large content of fines in OCC pulp. Which basically, initiates from repeated recycling of OCC, suggested a new direction for OCC mills. This proposal indicates that if the fiber is fractionated and long fiber refined and mixed with unrefined short fraction, many advantages can be drawn. This work was concentrated on evaluating this opinion. OCC pulp was collected from the point that was ready to make board. The pulp was fractionated using pressure screen at laboratory screen. And after mechanical treatment made into handsheets and test for some strength properties, which are important, either for paper or packaging mills. It was observed that, some properties such tensile, burst or internal bonding suffer considerably during fractionation. On the other hand, some properties, such as bending strength get benefit. These results were discussed thoroughly in the text. |
