Abstract: The invention concerns a method of manufacturing paper or board, the paper or board obtained by the method, and a method of producing a tray from the board. In a fibrous stock for papermaking is incorporated an amount of polymer coated fibrous particles, which even have a foaming agent such as moisture contained therein. A web is formed from the fibrous stock on a forming fabric of a paper or board machine, followed by pressing and drying to a finished paper or board. As the paper or board is sufficiently heated the foaming agent within the particles evaporates, causing expansion and foaming of the polymer coating, which adds to malleability of the board as it is moulded into a shaped article such as a board tray. The invention even covers production of doubly coated fibrous particles for use in said methods, the inner coating layer being of a foamable polymer with a higher melt flow rate and the outer coating layer being of a non-foaming polymer of a lower melt flow rate.

Abstract: A method and a system for preparing xylan and calcium carbonate, xylan, a cellulose fibre, and precipitated calcium carbonate. The method includes extracting xylan from cellulose fibres with sodium hydroxide to form a mixture containing cellulose fibres and an extract solution containing xylan; removing the cellulose fibres from the mixture to isolate the extract solution; adding carbon dioxide to the isolated extract solution to form a mixture containing a liquid brightener and precipitated xylan; separating the brightener from the mixture to isolate the precipitated xylan; adding calcium hydroxide to the separated brightener to form a mixture of precipitated calcium carbonate and liquid sodium hydroxide; and removing the sodium hydroxide from the mixture to isolate the calcium carbonate.

Abstract: The invention relates to a method for isolating xylan from plant material. In the method, cellulose fibres which contain xylan are used, advantageously cellulose fibres from hardwood; and xylan is extracted (20) from said cellulose fibres by means of sodium hydroxide for forming an extract solution (17) that contains xylan; cellulose fibres are removed from said mixture that contains cellulose fibres and extract solution (17), for isolating said extract solution from said mixture; carbon dioxide (14) is added to said extract solution (17) for isolating xylan, wherein liquid brightener (18) and precipitated xylan (12) are formed; calcium hydroxide (16) is added to said isolated brightener (18), for forming precipitated calcium carbonate and liquid sodium hydroxide (15); and sodium hydroxide is removed from said mixture that contains sodium hydroxide and precipitated calcium carbonate, for isolating calcium carbonate from said mixture. Furthermore, the invention relates to a system for isolating xylan from plant material, and to xylan, calcium carbonate, cellulose fibre and use of xylan.

Abstract: An aqueous dispersion comprising a non-settling colloidal hemicellulose ester polymer in water and a method of producing the same. In the method an esterified hemicellulose is provided wherein at least a part of the esterifying groups are derived from a lower alkanoic acid; the esterified hemicellulose is dissolved in an alkanoic acid to produce a solution; and the solution is dispersed into water to produce an aqueous dispersion of the hemicellulose ester. The present compositions, containing hemicellulose derivatives of low solubility, can be used in paper, paperboard and other fibre-based materials, for paints, surface treatments for polymer films, and polymer films as such, and can be applied as binders.
