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 object of the invention is a method for improving strength and retention in paper production. According to the invention, an anionic microfibrillated cellulose-containing composition is arranged in the fiber suspension and 0.1-10% 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 an anionic microfibrillated cellulose-containing composition and the microparticle component is replaced with an anionic microfibrillated cellulose-containing composition to improve the strength and retention of the product being formed. for improvement. In addition, the object of the invention is a corresponding paper product.
