摘要： The present invention relates to dry cellulose filaments and particularly those that are re-dispersible in water. Dry cellulose filaments comprise at least 50% by weight of the filaments having a filament length up to 350 μm; and a diameter of between 100 and 500 nm, wherein the filaments are re-dispersible in water. Also described here is a film of dry cellulose filaments comprising the filaments described, wherein the film is dispersible in water. A method of making a dry film of cellulose filaments is also described that includes providing a liquid suspension of the cellulose filaments described; and retaining the filaments on the forming section of a paper or tissue making machine or on a modified paper or tissue making machine. The film can be optionally converted to powders or flakes for shipment, storage or subsequent uses. The filaments, the film, the powders or flakes and the method are in a preferred embodiment free of additives and the derivatization of the filaments.

摘要： The present description relates to a process of producing a dry mixed product comprising cellulose filament (CF) and a carrier fiber, and a dry mixed product of re-dispersible cellulose filament and a carrier fiber that permits the CF to retain its dispersibility in water and hence superior reinforcement ability in papermaking furnishes, composite materials, or other materials where CF is used. The process comprises mixing a water suspension of never-dried CF with a cellulose fiber pulp carrier followed by thickening to a suitable concentration so that it can be further processed and dried in a conventional device such as a dryer can of a pulp machine or a flash dryer.

摘要： There are provided gypsum panels, sheets and multi-layer sheets as well as methods of preparation thereof. For example, there are provided cellulose filament-reinforced gypsum panels, sheets and multi-layer sheets and methods of preparation thereof. For example, in such gypsum panels, sheets and multi-layer sheets gypsum is bound with cellulose filaments to strengthen the gypsum panels, sheets and multi-layer sheets. The cellulose filament-reinforced gypsum panel can be, for example, a core comprising a honeycomb or corrugated structure. There are also provided aqueous suspensions comprising cellulose filaments and CaSO4.2H2O.

摘要： A novel method is disclosed to make cellulose filaments (CF) from wood or other plant fibers with lower energy consumption. The method consists of multi-stage, high consistency refining, followed by low consistency refining or by low consistency, non-refining mechanical treatment, of wood or other plant fibers. The total specific refining energy for the multi-stage, high consistency refining is preferably 2,000-18,000 kWh/t, and more preferably 2,000-12,000 kWh/t. The CF produced can be used as a superior reinforcement additive in the production of paper, tissue or paperboard and in the production of plastic composites. It can also be used as a viscosity or rheology modifier in food products, coatings or drilling muds. The CF produced can also be used to make strong films for application in packaging and in composites.

摘要： A method of producing ultra-low density fiber composite (ULDC) foam materials using natural fibers with gas injection through liquid foaming is disclosed, wherein in a particular embodiment includes also cellulose filaments. The method includes a continuous overflow foaming process and a novel apparatus to produce the ULDC materials. The disclosed ULDC composite foam produced includes moisture, mold, decay and fire resistant properties which can be used for building thermal and acoustic insulations, protection packaging, air filter products, hygiene products. The apparatus comprise a vessel, counter rotating dual impellor, a plurality of baffles and gas injection that produce.
