FIELD: chemistry.
SUBSTANCE: claimed invention relates to method of obtaining suspensions of nanofibrous cellulose and nanofibrous cellulose obtained by said method. Method of obtaining suspensions of nanofibrous cellulose includes the following stages: (a) supply of cellulose fibres; (b) supply of at least one filling agent and/or pigment; (c) mixing cellulose fibres and at least one filling agent and/or pigment; (d) fibrillation of cellulose fibres in presence of at least one filling agent and/or pigment, with fibres being at least partially milled to primary fibrils in the course of fibrillation. Filling agent and/or pigment is selected from the group, containing precipitated calcium carbonate; natural calcium carbonate and their mixtures.
EFFECT: increased effectiveness of method for obtaining suspensions of nanofibrous cellulose, increase of milling degree are provided.
