1. A method for producing a product in papermaking comprising:
adding a composition comprising anionically modified microfibrillated cellulose to a fiber suspension at a concentration of 0.1 to 10 wt-% anionically modified microfibrillated cellulose by weight of the fiber suspension to produce a modified fiber suspension; and forming the product from the modified fiber suspension, wherein adding the anionically modified microfibrillated cellulose to the fiber suspension improves the strength of the product. |
