摘要： A process for producing microfibrillated cellulose comprises providing a slurry comprising cellulosic fibers, treating the slurry with an enzyme, mechanically treating the slurry so that the fibers are disintegrated wherein the mechanical treatment and the treatment with the enzyme is performed simultaneously in a single treatment step. In this way it is possible to produce microfibrillated cellulose (MFC) in an improved and energy efficient way. A microfibrillated cellulose is produced according to the process.

摘要： The present invention relates to a method for dissolving cellulose. The method comprises—introducing cellulosic raw material,—treating the cellulosic raw material in an enzymatic treatment process,—mixing the cellulosic raw material after the enzymatic treatment in an aqueous solution in order to obtain an aqueous intermediate product containing the cellulosic raw material of at least 3.5 wt.-%, alkali metal hydroxide between 3.5 wt.-% and 7 wt.-% and zinc salt,—freezing the intermediate product to a solid state, and -melting the frozen intermediate product. The present invention also relates to a cellulosic product obtained from a solution comprising dissolved cellulose.
