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 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.
Claims20
A wet-laid tissue product comprising at least about 5 weight percent regenerated cellulose fibers and wood pulp fibers, the product has a geometric mean slope, having units of grams, less than or equal to 2.2152 (GMT)+893.36, where GMT is the geometric mean tensile strength having units of grams per three inches (g/3″) and wherein the GMT is from about 2,000 to about 4,000 g/3″.
A paper towel comprising a creped throughdried tissue ply having an air-side and a fabric-side, a latex binder disposed on the air-side of the sheet ply, at least about 5 weight percent regenerated cellulose fibers and wood pulp fibers, the paper towel having a GMT from about 2,000 to about 4,000 g/3″ and a TS7 value less than about 20.
