    Abstract: The present invention provides a method for extracting polymeric pentose, preferably xylan, from a polymeric pentose containing liquid/slurry, preferably black liquor, comprising the following steps: a) providing a polymeric pentose containing liquid/slurry; b) concentrating the polymeric pentose by membrane separation of a said polymeric pentose containing liquid/slurry; and c) adding alcohol to the concentrate obtained in step b) and subsequently acidifying said concentrate obtained in step b) for precipitating polymeric pentose whereby a polymeric pentose product, or an intermediate polymeric pentose product, is obtained. In this above way polymeric pentose, e.g. xylan, is separated whereby the use of methanol (less lignin must be kept in solution) and acid (less acid which buffers the pH- decrease) become much lower. The present invention also provides according to a second aspect a polymeric pentose product or an intermediate polymeric pentose product obtainable by the method according to the first aspect. The present invention also provides according to a third aspect use, preferably for the production of food additives or as chemical feed stock, of the polymeric pentose product or the intermediate polymeric pentose product of the second aspect of the invention.

    Abstract: The present invention relates to a process for replacing intra-fiber liquid in fibers by a replacement liquid, comprising the following steps; compressing the fiber cake to such a degree that a substantial quantity of the intra-fiber liquid is expressed to the space between the fibers and partially out of the fiber cake, forcibly supplying the replacement liquid to the fiber cake during the compression and thus replacing the intra-fiber liquid from the space between the fibers and letting the fibers expand while supplying additional replacement liquid which is thus further absorbed by the expanding fibers. It also relates to an arrangement for replacing intra-fiber liquid in fibers with a replacement liquid comprising a device (1, 4, 5) for compressing the fiber cake in such a degree that a substantial quantity of intra-fiber liquid is expressed to the space between the fibers and partially out of the fiber cake , a first device (6, 8, 9) for forcibly supplying the replacement liquid to the fibers during the compression and a second device (7) for supplying additional replacement liquid immediately after the device for compression arranged in an expansion area where the fibers are allowed to expand after the compression while absorbing replacement liquid. The object of the present invention is to get rid of or significantly reduce the content of contaminating material in not only the areas between the fibers in a fiber cake but also in the fiber wall pores and the lumen and replace this liquid by a replacement liquid.

    Abstract: A method of modeling and interactively visualizing the appearance of a surface. A directed radiance model of an irradiated surface is provided, where energy is distributed as a function of spectral wavelength. The surface is divided in a plurality of part-surfaces (XI, YI), and spectrally resolved directed radiance values of each part-surface in an interval of enforced inclinations (ZI) of a simulated or real sample holder are determined for providing spectral and angular resolution. Sets of directed radiance values among the determined spectrally resolved directed radiance values, that simulate certain viewing angles of the irradiated surface are selected and visually presented as images of the irradiated surface by a graphic computer interface. The images in the graphic computer interface are dynamically and interactively manipulated to thereby simulate manipulation of the irradiated physical surface.

    Abstract: A method and apparatus for obtaining a basis on which the gloss quality of a sample surface of a sample, such as a paper sheet, can be determined by illuminating the sample surface and registering the intensity of the reflected light. With the intention of enabling several different types of gloss variation investigations to be made on a sample surface essentially in accordance with known principles of gloss facet approximation, it is proposed, among other things, that the sample surface (80) is exposed in an image registering area (44) by controlled rotary movement of the sample surface through the image registering area or by controlled rotary movement of the image registering area over the sample surface, wherein the intensity of the light reflected from a plurality of spatially well defined part-surfaces of the sample surface is registered several times during this rotary movement while, at the same time, determining the positions of the part-surfaces in the image registering area (44), and in turn the viewing angle, so as to establish what we here define as an image volume which is representative of the registered light intensity as a function of the position of the part-surfaces within the sample surface and of the respective viewing angle.

    Abstract: A method for the manufacturing of nanocellulose. The method includes a first modification of the cellulose material, where the cellulose fibers are treated with an aqueous electrolyte-containing solution of an amphoteric cellulose derivative. The modification is followed by a mechanical treatment. By using this method for manufacturing nanocellulose, clogging of the mechanical apparatus is avoided. Also the nanocellulose is manufactured in accordance with the method and uses of the cellulose.
