The use of hydrolytic enzymes and especially cellulases to improve dewatering in papermaking has been studied for decades. However, more in-depth work is still needed in order to clarify the effects of enzymes over the whole dewatering process in a paper machine. The aim of this study was to evaluate the possibility to improve dewatering properties of refined birch kraft pulp by the use of xylanase and endoglucanase (EG). The effects of the xylanase and EG treatment on dewatering were clarified by using a papermaking laboratory simulation chain comprising the Moving Belt Former (MBF), pressing simulator (MTS), and IR drying. With these methods it is possible to simulate the dewatering conditions on the wire, pressing and drying sections of a paper machine in the laboratory scale. In addition the enzyme effects on the fiber cell wall properties were examined with sophisticated methodology.
