METHOD OF APPLYING COMPOSITION CONTAINING CATIONIC TRIVALENT METAL AND LOOSENER AND SHEET OF LOOSE CELLULOSE MADE THEREFROM Russian patent published in 2017 - IPC D21C9/00 

Abstract RU 2610240 C2

FIELD: wood working industry.

SUBSTANCE: proposed is a method of making a sheet of loose cellulose involving contacting of at least one cationic trivalent metal, a salt thereof or their combination with a composition containing fibres of loose cellulose and water, at the first pH value to form a mixture of loose cellulose; forming a fabric from this mixture of loose cellulose, application of at least one loosening surfactant onto the fabric and raising the pH value to the second pH value, which is greater than the first pH value, for making a sheet of loose cellulose. Also proposed is a sheet of loose cellulose including the fabric containing fibres of loose cellulose, at least one cationic trivalent metal, its salt or their combination, at least one loosening surfactant and having the energy of separation into fibres of <145 kJ/kg. Also proposed are products and applications of the sheet of loose cellulose.

EFFECT: proposed is a method of making a sheet of loose cellulose.
