A method for producing a fibrillated cellulose material, including the steps of: (a) forming a swelling agent comprising at least one inorganic salt (or hydrate thereof) as a free solid, optionally in a liquid medium, in a fluidised state, (b) contacting a cellulosic material with the swelling agent to form a swollen cellulosic material; (c) optionally, adding further liquid to facilitate mixing; (d) optionally, rinsing the swollen cellulosic material to remove swelling agent; and (e) fibrillating the swollen cellulosic material to form a micro- or nano-fibrillated cellulose material. |
