摘要： A process in preparing a high absorption fluff pulp which can be shredded at a low power consumption to fluff, wherein to the pulp suspension before or on the wire is added ampholytic tensides and/or tensides which are cationic at low pH values and nonionic at high pH values, the pH value being kept sufficiently low for the tensides to be in cationic form, whereupon the pH value is increased to such an extent that the tensides are transferred into the anionic and nonionic form respectively, which pH increase takes place just before the pulp web leaves the wire or before any of the presses or between the last press and the drying section or in the drying section or in connection with the feeding of the pulp into the fluffing machine.
