Abstract
The invention concerns an improved method for making paper which consists in using as main retention agent a branched polymer prepared in invert emulsion and bentonite as secondary retention agent (dual type system). The two additions are separated by a step for shearing the fibrous suspension (or mass). The invention enables to obtain a highly improved retention and also highly improved dewatering.
Moreover, it enables to reduce the bentonite content in the white water.
Moreover, it enables to reduce the bentonite content in the white water.
