FIELD: textile; paper.
SUBSTANCE: composition contains a fibrous mixture from chemical and thermomechanical mass and cellulose. The fibrous mixture contains birch leached chemical and thermomechanical mass with extent of grinding 60-125 ml (CSF) and cellulose with grinding extent of 350-500 ml (CSF) at the specified ratio of components. The cellulose in the fibrous mixture is a leached pine sulfate cellulose and/or pine sulphite cellulose, or pine cellulose, and/or leaf cellulose.
EFFECT: expansion of leaf-bearing soft woods due to using birch leached chemical and thermomechanical mass to prepare a fibrous semi-finished product to produce paper with high physical mechanical indices to ensure extent of whiteness.
