Abstract: The present invention relates to a method for manufacturing an intermediate product that can be stored and transported and efficiently converted into microfibrillated cellulose with limited energy input at the time of conversion. More specifically, the invention involves the use of dewatered carboxymethylcellulose or carboxylated cellulose fiber having a low degree of substitution and a high amount of additives.

Abstract: The invention relates to a method of producing oxidized or microfibrillated cellulose (MFC). According to the invention there is provided an aqueous pulp suspension with a consistency of at least 15 %, and at least one oxidant is added to the suspension to oxidize cellulosic hydroxyl groups in the suspension under mechanical mixing or shearing. The oxidized suspension, washed and diluted to a lower consistency, is subjected to homogenization to yield gel-like MFC. Alkali hypochlorite may be used as oxidant, and preferred mediating oxidation catalysts are AZADO and TEMPO. Alkali bromide may be used as a cocatalyst. The MFC product, which as a suspension has an increased viscosity, is suitable as a means of regulating viscosity or for production of films and composites.

Abstract: Den föreliggande uppfinningen avser ett förfarande för framställning av cellulosakarbamat, vilket förfarande innefattar följande steg: tillhandahållande av en aldrig torkad massa, tillsats av urea och blandning av nämnda massa med nämnda urea, mekanisk behandling av nämnda blandning, torkning av blandningen, samt uppvärmning av den förhållandevis torra blandningen för att på så sätt tillhandahålla ett cellulosakarbamat. Den föreliggande uppfinningen avser även ett cellulosakarbamat som kan erhållas genom nämnda förfarande, användning av nämnda cellulosakarbamat samt en spinnlösning innefattande nämnda cellulosakarbamat.

Abstract: A method is provided for preparing a fibrous material of crosslinked microfibrillated cellulose. Phosphorylated microfibrillated cellulose is formed into a fibrous material; and then said fibrous material is post-treated (e.g. by heat-treatment) to provide crosslinking between the phosphorylated microfibrillated cellulose. Fibrous materials such as filaments, mats or films, and hygiene products comprising such materials are also described.
