Abstract: The method of the invention relates to a method of manufacturing a fibrous, oxygen barrier film by casting a suspension comprising microfibrillated cellulose onto a non-porous substrate in a number of subsequent steps with intermediate drying. The invention enables an efficient method to manufacture an MFC film by casting technology without the problems of cracks or voids formed in the film. By applying the MFC in several layers, with in-between drying, the distance the water has to diffuse through is shorter, whereby the evaporation is more efficient and the film properties are not negatively affected by the drying.

Abstract: The present invention provides a method for production of cellulose ethers in a high solids process substantially without use of organic solvents as reaction and/or washing medium. In the method of the invention the first alkalization step is carried out by using high solids content cellulose pulp and solid sodium hydroxide. This is followed by an etherification step where the solids content is preferably further increased and the use of solid etherification reactant is preferred. As no organic solvents are used as reaction media the invented method enables production of cellulose ethers directly from never dried pulp with significant savings in energy and investment costs. The method is especially suitable for the production of carboxymethyl cellulose sodium salt (CMC) with low degree of substitution (DS

Abstract: The present invention relates to a method for manufacturing microfibrillated polysaccharide, preferably microfibrillated cellulose. The invention also relates to microfibrillated cellulose obtainable by the method and use of the microfibrillated cellulose. The method of manufacturing microfibrillated cellulose comprises the following steps: a) Providing a hemicellulose containing pulp, b) Providing wood degrading enzymes c) Mixing pulp and enzymes d) Keeping the mixture in a continuous, flowing system of essentially cylindrical geometry (for example in a plug-flow reactor), e) Conveying the mixture to one or more mixing zones for recirculating and homogenizing the mixture, and f) Harvesting microfibrillated cellulose with a relatively narrow size distribution during the recirculation.
