| abstract | PAPER PROCESSING PAPER PRODUCTION The present invention relates to a papermaking process, the process of which comprises: 1) providing an aqueous suspension comprising cellulosic fibers; (ii) adding to the suspension after the last high shear point: (a) a first anionic component, which is a water soluble anionic organic polymer; (b) a second anionic component which is a branched or water-dispersible anionic organic polymer having an unexpanded particle size of less than 1000 nm; and (c) a third anionic component, which is an anionic silicon material; and (iii) dehydrating the suspension obtained to shape or form a paper. The invention further relates to a composition comprising the first, second and third anionic components, and the use of the composition as a flocculating agent in pulp and paper production and water purification. |
