| 20120136146 | PROCESS FOR THE PRODUCTION OF MICROFIBRILLATED CELLULOSE AND PRODUCED MICROFIBRILLATED CELLULOSE - A process for producing microfibrillated cellulose comprises providing a slurry comprising cellulosic fibers, treating the slurry with an enzyme, mechanically treating the slurry so that the fibers are disintegrated wherein the mechanical treatment and the treatment with the enzyme is performed simultaneously in a single treatment step. In this way it is possible to produce microfibrillated cellulose (MFC) in an improved and energy efficient way. A microfibrillated cellulose is produced according to the process. | 05-31-2012 |
| 20120135506 | PROCESS FOR PRODUCING MICROFIBRILLATED CELLULOSE - A process for treating cellulosic fibres comprising pre-treating the fibres with an enzyme in a first enzymatic treatment followed by mechanical pre-treating the fibres in a first mechanical treatment and a second enzymatic treatment followed by a second mechanical treatment of the fibres to form micofibrillated cellulose. In this way it is possible to produce mircofibrillated cellulose (MFC) in an improved and energy efficient way. | 05-31-2012 |
| 20120132381 | NOVEL PAPER AND METHOD OF MANUFACTURING THEREOF - The invention relates to a method for manufacturing nanostructured paper or board and a novel paper or board. The method comprises providing a liquid suspension of nanocellulose-containing material, forming a web from the suspension and drying the web in order to form paper or board. According to the invention, the water content of the suspension at the time of beginning of the drying is 50% or less by weight of liquids so as to form a paper or board having an average pore size between 200 and 400 nm. By means of the invention, very opaque paper, for example for printing applications, can be manufactured with low energy consumption. | 05-31-2012 |
| 20120132380 | METHOD OF MANUFACTURING PAPER AND PRODUCTS OBTAINED BY THE METHOD - The invention relates to a method for manufacturing nanostructured paper or board and a novel paper or board. The method comprises providing a liquid suspension of nanocellulose-containing material, forming a web from the suspension, and drying the web in order to form paper or board. According to the invention the water content of the suspension from which the web is formed is 50% or less by weight of liquids. By means of the invention, energy consumption of paper manufacturing can be significantly reduced. | 05-31-2012 |
| 20120097352 | TREATMENT OF FIBRES TO ENDURE PROCESSING - The invention relates to a method of treating chemical pulp fibres by a polymerizing hydroxy acid, the fibres thus obtained and the products refined from them. In the method, the hydroxy acid reacts with the reactive groups of the fibres in the presence of a catalyst, forming ester bonds. The following units of the same hydroxy acid are oligomerized and/or polymerized to these grafted acid residues. The fibres thus treated and the products refined thereof endure better processing stages that include drawing and stretching than untreated fibres. | 04-26-2012 |
| 20120090798 | METHOD OF MAKING PAPER - The invention relates to a method of making a paper or paper board, in which method cut pulp is prepared by cutting basic cellulosic fiber pulp at the consistency of at least 25% so that the average fiber length of the basic pulp is decreased by more than 25% and the SR number of the cut pulp is at most 20% higher than that of the basic pulp, and the cut pulp is used as a raw material in the preparation of a stock. | 04-19-2012 |
