Abstract (en)
The present invention relates to a process for the preparation of a high freeness beaten low lignin pulp with a high strength. More particularly, the present invention relates to a process for the preparation of a high freeness beaten low lignin pulp that is produced from a pulp with a low lignin content, wherein said pulp with a low lignin content is subjected to a beating process under relatively high compression forces and relatively low shear forces.
