Abstract

Foreliggende oppfinnelse angår en fremgangsmåte for fremstilling av papir som omfatter: (i) tilveiebringelse av en vandig suspensjon omfattende cellulosefibre, (ii) tilsetting til suspensjonen etter alle steder med høyt skjær: en første polymer som er en kationisk polymer som har en ladningstetthet over 2,5 meq/g; en andre polymer; og en tredje polymer som er en organisk eller uorganisk anionisk polymer; og (iii) avvanning av den oppnådde suspensjonen for å danne papir.The present invention relates to a process for making paper comprising: (i) providing an aqueous suspension comprising cellulose fibers; (ii) adding to the suspension after all high shear sites: , 5 meq / g; a second polymer; and a third polymer which is an organic or inorganic anionic polymer; and (iii) dewatering the suspension obtained to form paper.
