  • Process of making paper and paperboard products
    Patent number: 11846072
    Abstract: The present invention is directed to products, such as paper and paperboard products, comprising a substrate containing a recycled cellulose-containing material and top ply comprising one or more inorganic particulate material; 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 a stage when the substrate comprising a wet web of pulp 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.

  • Through-air dried tissue products comprising regenerated cellulose fiber
    Patent number: 11795624
    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.
