Abstract
The possibility of modification of mineral filler-calcium carbonate by nonofiber cellulose is shown. Bacterial cellulose synthesized by bacterial strain Komagataeibacter rhaeticus CALU-1629 in the amount of 1–5% to the mass of a.s. fiber was used as nanofiber cellulose. It is established that modification of the filler with bacterial cellulose allows to obtain paper with the content of filler up to 50% providing its retention in the paper by 95–98% without the use of retaining agents. Modification of the filler with bacterial cellulose allows to increase the mechanical strength of paper with filler and reduce the absorbency of paper, which will make it possible to significantly reduce the use of cationic starch and bonding agents in paper production.
