Abstract

Keksinnön kohteena on menetelmä lujuuden ja retention parantamiseksi paperin valmistuksessa. Keksinnön mukaisesti järjestetään anionista mikrofibrilloitua selluloosaa sisältävää koostumusta kuitususpensioon ja lisätään 0,1 – 10 p-% mikrofibrilloitua selluloosaa kuitususpension massasta ja korvataan ainakin osa retentiokemikaaleista ja/tai lujuuskemikaaleista anionista mikrofibrilloitua selluloosaa sisältävällä koostumuksella ja korvataan mikropartikkelikomponentti anionista mikrofibrilloitua selluloosaa sisältävällä koostumuksella muodostettavan tuotteen lujuuden ja retention parantamiseksi. Lisäksi keksinnön kohteena on vastaava paperituote.The invention relates to a method for improving strength and retention in papermaking. According to the invention, a composition containing anionic microfibrillated cellulose is provided in a fiber suspension and 0.1 to 10 wt% of microfibrillated cellulose is added to the mass of the fiber suspension and at least part of the retention chemicals and/or strength chemicals are replaced with a composition containing anionic microfibrillated cellulose and the microparticle component is replaced with a composition containing anionic microfibrillated cellulose to improve the strength and retention of the product formed. The invention also relates to a corresponding paper product.
