Abstract

Process for the manufacture of paper which provides a non-polluting method based on ionic lattices for giving wet strength. The process is characterized by successively adding to the fibrous composition a cationic polyelectrolyte, then a sulfonated anionic polyelectrolyte, for example, the acrylamide and acryloxyethyltrimethylammonium chloride copolymer and the acrylamide and 2-acrylamido-2-methylpropane sulfonate copolymer. The polyelectrolytes are used in an amount of 0.02 to 2.5 % by weight in relation to the dry weight mass of the cellulosic composition entering the head box. The process is non-polluting; and no AOX, formaldehyde or epichlorhydrine are produced when it is carried out. The paper formed is easily repulpable.
