Abstract
A method for the preparation of cellulose solutions, comprises: (a) dispersing pulp in an aqueous amine oxide solution, and (b) reacting it with xylanase or an enzyme mixture containing xylanase. USE - The cellulose solutions produced by the above method can be used for the preparation of, e.g. cellulose fibres, films or other articles. ADVANTAGE - The treated cellulose dissolves more quickly in aqueous amine oxide solutions.
