摘要： A paper product having improved printing characteristics and a method of making the paper product. This paper product has a fibrous substrate and top layer of surface enhanced pulp fibers that is integrally coupled to the top surface of the fibrous substrate. The paper product is produced by providing an aqueous slurry formed from a blend of cellulosic fibers and water and at least partially dewatering the aqueous slurry of cellulosic fibers and water to form the fibrous substrate. Subsequently, a surface treatment formed from an aqueous composition of water and surface enhanced pulp fibers is applied to the top surface of the fibrous substrate and thereafter the treated fibrous substrate is dried to form a paper product having enhanced printing characteristics.

摘要： The present invention relates to a method of making a fiber-reinforced cementitious composite material which finds widespread applicability in a variety of construction and related applications. The composite comprises cellulosic fibrous material in order to provide the composite with the desired performance characteristics. Notably, at least a portion of the cellulosic fibrous material comprises surfaced enhanced pulp fiber, which desirably enhances the processing characteristics of the material, as well enhancing the characteristics of the finished composite product. The method of making a fiber-reinforced cementitious composite comprising the steps of providing a cementitious composition, and providing cellulosic fibrous material. The present method further includes blending the cementitious composition and the cellulosic fibrous material to form the cementitious composite. The surface enhanced pulp fiber preferably comprises approximately 1-10%, by weight, of the cellulosic fibrous material, and the cellulosic fibrous material exhibits an enhanced Bauer-McNett long fiber fraction. The cellulosic fibrous material preferably exhibits at least a 10% increase in length-weighted average fiber length (LWAFL), in comparison to a cellulosic fibrous material which is devoid of surface enhanced pulp fiber. The cellulosic fibrous material requires relatively reduced refining energy, in comparison to a cellulosic fibrous material which is devoid of surface enhanced pulp fiber, to reach a predetermined freeness CSF (Canadian Standard Freeness) value.

摘要： A method of making a market pulp can include separating a slurry comprising a plurality of pulp fibers into at least first and second pulp feeds. The first pulp feed can be refined at least by, for each of one or more mechanical refiners, introducing the first pulp feed between two refining elements of the refiner and rotating at least one of the refining elements, each of the refining elements comprising a plurality of bars and a plurality of grooves, where a width of each of the bars is less than or equal to 1.3 mm and a width of each of the grooves is less than or equal to 2.5 mm. The refiner(s) can consume at least 300 kWh per ton of fiber. The refined first pulp feed and second pulp feed, which is not refined, can be combined to produce a third pulp feed that can be dried.

摘要： The present invention relates to a method of making a paper product having Improved printing characteristics. This is achieved by forming a fibrous substrate, and applying a surface treatment which comprises an aqueous composition. Notably, the aqueous composition includes surface enhanced pulp fibers, with the placement of the surface enhanced pulp fibers optimizing their functionality, with surface placement by use of a paper machine size press desirably facilitating a reduction in the typical starch usage. The present method comprising the steps of providing a aqueous slurry comprising a blend of cellulosic fibers and water and dewatering the aqueous slurry of cellulosic fibers and water to form a fibrous substrate. The present method further includes applying a surface treatment to the fibrous substrate, wherein the surface treatment comprises an aqueous composition including surface enhanced pulp fibers, to form a treated fibrous substrate, and thereafter drying the treated fibrous substrate to form a paper product having enhanced printing characteristics.

摘要： Various embodiments of the present invention relate to surface enhanced pulp fibers, various products incorporating surface enhanced pulp fibers, and methods and systems for producing surface enhanced pulp fibers. Various embodiments of surface enhanced pulp fibers have significantly increased surface areas compared to conventional refined fibers while advantageously minimizing reductions in length following refinement. The surface enhanced pulp fibers can be incorporated into a number of products that might benefit from such properties including, for example, paper products, paperboard products, fiber cement boards, fiber reinforced plastics, fluff pulps, hydrogels, cellulose acetate products, and carboxymethyl cellulose products. In some embodiments, a plurality of surface enhanced pulp fibers have a length weighted average fiber length of at least about 0.3 millimeters and an average hydrodynamic specific surface area of at least about 10 square meters per gram, wherein the number of surface enhanced pulp fibers is at least 12,000 fibers/milligram on an oven-dry basis.
