Abstract: 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.

Abstract: 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.

Abstract: 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.
