Abstract
The present invention relates to a method of producing microfibrillated cellu-lose (MFC) comprising (i) providing cellulosic material, (ii) drying the cellulosic material so that specific surface area (SSA), when measured with BET-method, is at most 10 m2/g, and (iii) subjecting the dried cellulosic material to mechanical treatment. The present invention additionally relates to microfibril-lated cellulose produced with the method of the present invention.
