FLOCS OF FILLERS COMBINED WITH CELLULOSE MICRO AND NANOFIBRILS FOR USE IN THE PRODUCTION OF PAPER PRODUCTS WITH IMPROVED PROPERTIES

摘要

The present invention intends to solve the current problem of the need to use synthetic additives, which are costly and environmentally harmful, in the production process of paper products with improved properties, namely the increase of the tensile index (dry and wet-web), with increased filler retention, higher strength and air resistance (suitable for packaging applications), lower roughness, higher opacity and lower capillary water absorption. The invention consists in a product of flocs (1), for application in cellulosic fibres (2), consisting of mineral fillers conjugated with cellulose micro or nanofibrils, and in its use for the production of paper products and on the resultant paper products.
