Abstract

Uppfinningen avser ett förfarande för att förbättra hållfastheten och retentionen vid framställningen av papper. Enligt uppfinningen anordnas en sammansättning bestående av anjonisk mikrofibrillerad cellulosa i en fibersuspension och tillsätts 0,1 - 10 v-% mikrofibrillerad cellulosa beräknat på fibersuspensionens massa och ersätts åtminstone en del av retentionskemikalierna och/eller hållfasthetskemikalierna med sammansättningen bestående av anjonisk mikrofibrillerad cellulosa och ersätts en mikropartikelkomponent med sammansättningen bestående av anjonisk mikrofibrillerad cellulosa för att förbättra hållfastheten och retentionen av produkten som skall bildas. Dessutom avser uppfinningen en motsvarande pappersprodukt.The invention relates to a method for improving strength and retention in the production of paper. According to the invention, a composition consisting of anionic microfibrillated cellulose is arranged in a fiber suspension and 0.1 - 10 v-% microfibrillated cellulose calculated on the mass of the fiber suspension is added and at least part of the retention chemicals and/or strength chemicals are replaced with the composition consisting of anionic microfibrillated cellulose and a microparticulate component with the composition consisting of anionic microfibrillated cellulose to improve the strength and retention of the product to be formed. In addition, the invention relates to a corresponding paper product.
