LAMINATES
A method of manufacturing a laminate comprises providing a binder impregnated core layer by impregnating at least one fibrous layer with an aqueous core binder solution having a viscosity in the range 75 cP to 500 cP at a temperature of 20° C. and a bake-out solid content in the range 40 wt % to 85 wt %, in which the aqueous core binder solution comprises (i) at least 25% by dry weight of a) reducing sugar reactant(s) and nitrogen-containing reactant(s) and/or b) curable reaction product(s) of reducing sugar reactant(s) and nitrogen-containing reactant(s); and (ii) between 5% and 15% by weight of a non-aqueous solvent based on the total weight of the aqueous binder solution; providing a semi-finished assembly by assembling the binder impregnated core layer with a surface layer; and applying heat and pressure to the semi-finished assembly to cure the binder in the binder impregnated core layer and secure the core layer and the surface layer together.
Method for improving the water tolerance of bio-based CNF-films
The present invention relates to a continuous roll-to-roll process for improving the water tolerance of bio-based polymers, in particular cellulose nanofibrils (CNF) films. Furthermore, the invention provides a method, which combines surface modification/functionalization for improving water stability and wet strength, UV/Ozone treatment, corona treatment or plasma activation for purifying and activating the surface and thus increasing the reaction efficiency, and further hydrophobization of the surface of CNF film.
Nanocellulose aerogels and foams
The present disclosure provides a method for preparing an aerogel or a foam, the method comprising: forming a reaction mixture comprising a cellulose nanofibril gel, a first solvent, and one or more crosslinking agents under conditions sufficient to crosslink the gel; and contacting the crosslinked gel with a second solvent under conditions sufficient to dry the crosslinked gel, thereby forming an aerogel or foam.
CELLULOSE MICROPOWDER
The present invention relates to a cellulose powder usable for a satisfactory orally disintegrating tablet having excellent compression moldability and well-balanced tablet moldability and disintegration properties, which can obtain excellent ingestion feel without feeling roughness and dryness in the oral cavity, and more particularly to a cellulose powder with an average polymerization degree of 150 to 450, an average particle diameter of not less than 10 μm but less than 100 μm, and a primary particle ratio of 50% or more.
EXTRACTION METHOD
The present invention provides a method for extracting a solid purified product from an alkaline polysaccharide-containing precursor material, comprising the steps of: (a) neutralising the alkaline polysaccharide-containing precursor material with an acid and obtaining a neutralised solid polysaccharide-containing material; (b) mixing the neutralised solid polysaccharide-containing material with bleach to create a mixture; and (c) separating a solid purified product from the mixture.
A METHOD TO PRODUCE A FIBROUS PRODUCT COMPRISING MICROFIBRILLATED CELLULOSE
A method for the production of a fibrous product from a fibrous web, wherein the method comprises the steps of: providing a fibrous suspension comprising native microfibrillated cellulose, wherein the content of the microfibrillated cellulose of said suspension is in the range of 40 to 99.9 weight-% based on total dry solid content, said fibrous suspension further comprising organic acid, a metal salt or a mixture thereof, wherein the amount of organic acid, metal salt or mixture thereof is at least 2 weight-% based on total dry solid content of the suspension, —said fibrous suspension also comprising an uncharged, amphoteric or weakly cationic polymer having a molecular weight of at least 50000 g/mol, —said fibrous suspension also comprising an anionic polymer having a molecular weight of at least 10000 g/mol to said suspension, —providing said suspension to a substrate to form a fibrous web, wherein the amount of uncharged, amphoteric or weakly cationic polymer in said suspension is in the range of 0.1 to 20 kg/metric ton based on total dry solid content and wherein the amount of anionic polymer in said suspension is in the range of 0.01 to 10 kg/metric ton based on total dry solid content; and —dewatering said fibrous web to form a fibrous product.
Composition and method for active packaging and storage of fresh plant products
The present invention relates to a composition and method for active packaging of fresh plant products, in particular fresh plant based food products. The invention also relates to means for storage of fresh plant products and to a method for continuous production and controlled release of volatile oxidation products of lipids in packages or in the vicinity of fresh plant based goods.
PROCESS FOR PRODUCTION OF FILM OR COATING COMPRISING CELLULOSIC NANOMATERIAL
The present invention is directed to a process for manufacturing a film or coating comprising high amounts of cellulosic nanomaterial. According to the present invention, a screen printing press, such as a rotary screen press, is used to create a film or coating comprising cellulosic nanomaterial. One benefit of the present process is that the suspension used in the printing process has a high dry content and high viscosity, thereby facilitating the process for manufacturing a film or coating comprising high amounts of cellulosic nanomaterial.
METHOD FOR PRODUCING RESIN COMPOSITION
A method for producing a first kneading step in which cellulose fibers having a weighted-average fiber length of 0.20 mm to 1.50 mm, a compatibilizing resin, and urea are introduced into a kneader and kneaded.
