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.

Method for manufacturing intermediate product for conversion into microfibrillated cellulose

A method for the production of highly refined or microfibrillated 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 mechanical means to obtain the final product. Dried cellulosic pulp is produced as an intermediate product of the method, having an average 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.

Method and intermediate for the production of highly refined or microfibrillated cellulose

The invention relates to methods of producing microfibrillated cellulose (MFC). According to the invention a fibrous pulp suspension is fibrillated mechanically at a consistency of less than 12.5%, dewatered to raise the consistency of the fibrillated suspension to at least 12.5%, and then subjected in the dewatered condition to further fibrillation. Alternatively an initially fibrillated fibrous pulp suspension may be dewatered and fibrillated in the dewatered condition, after which these dewatering and fibrillating steps are repeated one or more times so that pulp consistency is increased for each fibrillation step. The goals of raising the consistency between subsequent fibrillations are energy saving and an increased aspect ratio in MFC. The invention even comprises uses of the MFC product, e.g. as an additive for papermaking furnish or injection molded plastic composites.

Method of producing microfibrillated cellulose

A substantially dry composite material comprising a nanofibrillated polysaccharide and two or more additives, wherein the composite nanofibrillated polysaccharide is a microfibrillated cellulose and wherein the additives are lime milk and carbon dioxide, wherein the additives are allowed to react with each other and forming a precipitated calcium carbonate on the nanofibrillated polysaccharide, thereby forming a composite product comprising precipitated calcium carbonate and nanofibrillated polysaccharide.

Substantially dry composite comprising a nanofibrillated polysaccharide

The present invention relates to a compositions comprising a pyripyropene pesticide of the formula (I) or (II) as defined below and an adjuvant. The present invention relates also to methods of preparing and applying such compositions, as well as several uses thereof, and finally seeds, comprising said composition. The invention also relates to an aqueous pesticide formulation comprising a pesticide compound of the formula I as defined in claim 1 in the form of fine particles suspended in an aqueous liquid.
