Abstract

The mechanical properties of refined wet fibre surface was studied by assuming that the fibre surface is basically composed of micro- and nanofibrillated cellulose. The dynamic mechanical properties of microfibrillated cellulose show that already at consistencies below 2% it is clearly gel-like material. Comparison of wet fibre surface and CMF by using helium ion microscopy revealed their structural similarity and make possible to conclude that the fibre surface is gel-like material.
