Abstract

The present invention provides a process for the manufacture of mechanical pulp suitable for absorption purposes in which the wood raw material before, during and/or after mechanical defibration is treated with alkaline reacting components and in which the defibrized pulp is dried, optionally after sheet formation, characterized in that the pulp is dried in an alkaline buffered condition,
