PROCESS FOR PREPARING MECHANICAL PULP

摘要

The invention concerns an enzymatic process for pretreatment of wood raw-material which makes it possible to reduce the specific energy consumption of mechanical pulping and to improve the technical properties of the fibres. Cellobiohydrolase enzymes isolated from, e.g., the fungus Trichoderma reesei or other organisms or structural parts of these enzymes are used for the treatment.
