摘要 |
A method for concentrating fibril cellulose including subjecting aqueous fibril cellulose at a concentration of not higher than 5% to pressure filtration where water is removed from the fibril cellulose by applying pressure to the aqueous fibril cellulose, and continuing the pressure filtration continued to an end point where over 50% of the water initially present is removed from the fibril cellulose.
