Publication number: 20200207663Abstract: Cement composite boards comprising cellulose filaments (CF) and/or CF-containing pulp, are described. The composite boards have at least an improved modulus of rupture when compared with similar board that are free of CF. Methods for producing the CF and/or CF-containing pulp reinforced cement boards are also described. The CF cement composite board comprises: cellulose filaments (CF) and/or CF-containing pulp, and cement, wherein the CF has an aspect ratio of 200 to 5000, comprising a weight % of CF is from 1% to 20% by weight of the composite board. The composite boards herein described may have a modulus of rupture of more than 7 MPa.Type: ApplicationFiled: May 18, 2018Publication date: July 2, 2020Applicant: FPInnovationsInventors: Xiaolin CAI, Yuxia BEN, Xujun HUA, Michelle RICARD, Carole LAROUCHE, Xiang-Ming WANG

Patent number: 10683612Abstract: 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.Type: GrantFiled: September 13, 2017Date of Patent: June 16, 2020Inventors: Xujun Hua, Guy Roger Njamen Tchapda, Tom Owston, Patrick Neault, Thomas Hu, Yuxia Ben

Patent number: 10087580Abstract: 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.Type: GrantFiled: April 25, 2016Date of Patent: October 2, 2018Assignee: FPInnovationsInventors: Yuxia Ben, Gilles Dorris, Xiaolin Cai, Xujun Hua, Zhirun Yuan, Patrick Neault

Patent number: 10011528Abstract: 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.Type: GrantFiled: October 6, 2015Date of Patent: July 3, 2018Assignee: FPINNOVATIONSInventors: Gilles Dorris, Yuxia Ben, Qiaozhi An, Annie Dorris, Xiaoyu Wang

Patent number: 9994712Abstract: 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.Type: GrantFiled: November 5, 2014Date of Patent: June 12, 2018Assignee: FPINNOVATIONSInventors: Xiaolin Cai, Xixian (James) Deng, Nicolas Dery, Sebastien Lebel, Gilles Brunette, Gilles Marcel Dorris, Yuxia Ben, Michelle Ricard, Yaolin Zhang Zhang, Dian-Qing Yang, George Sacciadis

Patent number: 9803320Abstract: 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 ?m; 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.Type: GrantFiled: November 7, 2013Date of Patent: October 31, 2017Assignee: FPINNOVATIONSInventors: Gilles Marcel Dorris, Yuxia Ben, Thomas-Qiuxiong Hu, Patrick Neault

Publication number: 20170150749Abstract: The present invention relates to a structurally enhanced agricultural product containing cellulose filaments (CF), and a method for producing the structurally enhanced agricultural material into the sheets. Applying CF improves significantly the wet-web strength of the agricultural material sheets. The method comprises preparation of a pulp slurry of agricultural materials followed by mixing with a water suspension of CF or CF-containing cellulose fibers. The pulp blend is then used to produce an agricultural material sheet by papermaking process.Type: ApplicationFiled: November 25, 2016Publication date: June 1, 2017Inventors: Yuxia BEN, Xujun HUA, Michelle RICARD, Xiaoyu WANG
