摘要： A method for the production of cellulose films with at least one hydrophobic or less hydrophilic surface, or with at least one surface with a water contact angle () in a range from 55 to less than 00 is described. The method involves contacting the cellulose material with a hydrophobic solid material during the preparation of the cellulose films or with a vapour of a non-polar or polar aprotic solvent during or after the preparation of the cellulose films. Examples of the cellulose material are cellulose filaments (CF) made to have at least 50% by weight of the filaments having a filament length up to 350 µm and a filament diameter between 100 and 500 nm from multi-pass, high consistency refining of wood or plant fibers, and commercially-available sodium carboxymethyl cellulose. Examples of the hydrophobic solid material are hydrophobic polymers, poly(methylpentene) and poly(ethylene). Examples of the non-polar solvent are hexane and toluene. Examples of the polar aprotic solvent are acetone and ethyl acetate.

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.

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.
