Abstract: The invention concerns a method for the production of highly refined or micro- fibrillated cellulose (MFC), comprising the steps of treating cellulosic fibres to remove at least a major part of the primary wall of the fibres, drying the treated fibres, rewetting the treated fibres, and disintegrating the wetted fibres by me- chanical means to obtain the final product. The invention further concerns dried cellulosic pulp as an intermediate product of the method, having an aver- age fibre length of at least 0.4 mm, while less than 50 % of the primary wall material of natural untreated fibres is left in the intermediate product. Instead of transporting large amounts of dilute MFC dispersion the invention enables transport of the dry intermediate product to the MFC end user, who would complete the process by turning the intermediate product to final MFC by use of standard disintegrating devices.

Abstract: método para a preparação de éteres de celulose com um processo de alto conteúdo de sólidos, produto obtido e usos do produto a presente invenção proporciona um método produção de éteres de celulose em um processo para a de alto conteúdo de sólidos substancialmente sem o uso de solventes orgânicos como um meio de reação e/ou lavagem. no método de a invenção a primeira etapa de alcalinização é levada a cabo usando polpa de celulose com alto conteúdo de sólidos e hidróxido de sódio sólido. isto é seguido por uma etapa de eterificação onde o conteúdo de sólidos é preferivelmente ainda aumentado e o uso de sólido reagente de eterificação é preferido. como solventes não orgânicos são usados como meios de reação o método inventado permite a produção de éteres de celulose diretamente da polpa nunca seca com significante economia em energia e custos de investimento. o método é especialmente adequado para a produção de sal de sódio de carboximetil celulose (cmc) com baixo grau de substituição (ds

Abstract: The present invention relates to process for the production of a coated substrate comprising cellulosic fibres, the process comprising the steps of: i) providing a first substrate comprising cellulosic fibres and having a dry content of less than 50%; ii) applying a coating composition to the first substrate in an amount of more than 5 g/m2,,calculated as dry weight of the coating composition, wherein the coating composition comprises: - microfibrillated cellulose (MFC), and - optionally a water retention agent selected from carboxymethyl cellulose (CMC), anionic polyacrylamide (A-PAM),sodium polyacrylates, polyacrylic acid derivatives, guar gum, alginate, MFC prepared from carboxymethylated fibers, MFC prepared from oxidized fibers, MFC preparedby CMC- functionalised fibers, and/or combinations thereof; and iii) mechanically dewatering the first substrate. The present process provides an energy efficient coating process which can be performed online.
