摘要： Process for the Manufacture of Paper and Paperboard The present invention relates to a process of making paper or paperboard in which a cellulosic thin stock is provided and subjected to one or more shear stages and then drained and a moving screen to form a sheet which is dried, wherein the process employs a retention system which is applied to the thin stock, said retention system comprising as components i) a blend of different cationic polymers and ii) a microparticulate material, in which the blend of cationic polymers comprises, a) a cationic polymer having a charge density of from 0.5 and below 3 mEq per gram and a molar mass of greater than 700,000 Da, which cationic polymer is selected from polymers containing vinyl amine units and polyethylenimine, b) a cationic polymer having a charge density of below 3 mEq per gram and an intrinsic viscosity of at least 3 dl/g, wherein one of the components of the retention system is dosed into the thin stock after the final shearing stage and the other is dosed into the thin stock before the final shearing stage.

摘要： The present invention relates to surface-modified cellulose nanofibres, which are used to improve fibre-matrix adhesion, resulting in biodegradable nanofibrillated cellulose (NFC)-polyvinyl alcohol (PVOH) composites, which can be used to form structures such as films, with excellent mechanical performance. Particularly,the present invention relates to a bio composite resin composition wherein the surface of cellulose nanofibres have been chemically modified, a method for producing such composite resin composition and a casting-sheet composite body.

摘要： The present invention relates to an improved process for producing chemical cellulose pulp wherein biopolymers are added immediately before, during or after a bleaching step, depending on pulp characteristics and on process conditions used. The biopolymers according to the present invention are starch by an etherification reaction. This treatment results in a differentiated pulp having improved physical, chemical and mechanical properties when compared with cellulose pulps obtained by traditional processes. The use of said biopolymer alters the relations between important pulp properties rendering their application in papermaking process advantageous. This differentiation increases the possibilities of use and also of new applications, including for the substitution of pulps produced from other cellulose sources. Thus, the present invention also relates to a process for the preparation of paper, such as printing, writing, decorative, special or tissue-type papers, through the use of the cellulose pulps modified by the above process.

摘要： Printing paper product is made by multilayer technique starting from aqueous furnish comprising fibres and strength additive. In the aqueous furnish comprising fibres and strength additive, nanofibrillar cellulose and strength additive is fed in a middle layer to form a multilayer printing paper, and the paper product is made by dewatering of the furnish whereby the nanofibrillar cellulose and the strength additive migrate to the surface layers to increase the internal bond strength of the printing paper.
