A PROCESS FOR THE PRODUCTION OF PAPER

摘要

The present invention relates to a process for producing paper which comprises:
(i) providing an aqueous suspension comprising cellulosic fibres,
(ii) adding to the suspension after all points of high shear drainage and retention aids consisting of:
a cationic polysaccharide; and
a polymer P2 being an anionic polymer selected from anionic inorganic polymers and anionic acrylamide-based polymers;
(iii) dewatering the obtained suspension to form paper.
