Abstract: A tissue sheet includes softwood fibers and treated non-wood fibers from plants in the Poaceae family, wherein the treated non-wood fibers have less than 15 percent hemicellulose. Also, a tissue sheet consists essentially of softwood fibers and treated non-wood fibers, wherein the treated non-wood fibers have less than 15 percent hemicellulose. Customizing the tensile index and Canadian standard freeness (CSF) of fibers in a tissue sheet includes treating non-wood fibers by removing a portion of hemicellulose from the non-wood fibers; forming a tissue sheet comprising softwood fibers and the treated non-wood fibers; and adjusting the portion of hemicellulose removed from the non-wood fibers to achieve a desired the tensile index and Canadian standard freeness (CSF) of the treated non-wood fibers.

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.
