Abstract
The relation between freeness and the cationic demand of fibrous suspe nsions containing an industrial kraft hardwood bleached pulp (refined at different levels) is studied in this paper. The technique used was the colloidal titration. Results suggest that the fixation on cellulos ic fibres is attained through two mechanisms: ionic exchange and adsor ption by means of hydrogen bonds and van der Waals forces.
