Abstract: The present invention provides a wet-laid tissue product comprising regenerated cellulose fibers that can provide 25 percent or less of the total weight of the wet-laid tissue product. The regenerated cellulose fibers can have a linear density of less than about 1.5 dtex and a fiber length of less than 6.0 mm. The wet-laid tissue product can provide improvements in softness at a given strength. The products may also have improved wet physical properties when regenerated cellulose fibers are presented, such as improved wet tensile strength and wet burst. The improvement in wet physical properties does not come at the expense of dispersibility, as the products are readily dispersible and, in some instances, have improved dispersibility compared to similar products prepared entirely from conventional wood pulp fibers.

In this manner rolled bath tissue products may have a CD tensile from about 400 to about 1,000 g/76.2 mm and a detach strength from about 100 to about 500 g.

Abstract: The present invention provides multi-ply creped tissue products, and in particular embodiments creped wet-pressed tissue products, having substantially higher per-ply basis weights, such as from about 14.0 grams per square meter or greater.

Abstract: The present invention is directed to products, such as paper and paperboard products, comprising a substrate containing cellulose and top ply comprising microfibrillated cellulose and inorganic particulate, to methods of making such paper and paperboard products, and associated uses of such paper and paperboard products. The microfibrillated cellulose and inorganic particulate material are applied at the stage when the wet substrate is in the process of being formed on the wire of a papermaking machine, thereby avoiding the additional cost of more extensive equipment and machinery as well as in separate drying of a coating. The microfibrillated cellulose facilitates the application of inorganic particulate onto the surface of a wet paper or paperboard substrate when applied thusly, by trapping the inorganic particulate on the surface of the substrate and by giving the composite sufficient strength and a suitable pore structure to make it suitable for printing and other end-use demands.
