ABSTRACT:
A process of preparing microfibrillated cellulose comprising adding to never-dried cellulosic pulp an additive compound capable of substantially inhibiting hydrogen bonding of the fibrils in the cellulose and then drying the pulp and additive. Microfibrillation of a suspension of the cellulosic pulp is carried out at considerably increased efficiency if the additive compound is present prior to drying the pulp. The resulting MFC product can be dried and redispersed without substantial loss of viscosity.
