ABSTRACT:
A single or multi-ply tissue product includes at least one foam-formed ply incorporating at least about 100 ppm of forming-loop-incorporated surfactant, the ply includes from at least about 50% by weight to about 80% by weight of relatively short, high softness cellulosic fiber formed by chemical pulping of hardwood. The fibers have a weight average fiber length of between about 0.5 to about 2.2 mm, a coarseness of about 7 to about 14 mg of fiber per 100 m of fiber length (mg/100 m). The ply includes from at least about 20% by weight to about 50% by weight of relatively long strength-enhancing cellulosic fiber chosen from chemically pulped softwood fiber and chemi-thermo-mechanically pulped softwood fiber and mixtures thereof. The strength-enhancing cellulosic fiber have a weight average fiber length of about 2 to about 4 mm, a coarseness of about 14 to about 28 mg/100 m. Optionally, up to about 30% by weight of bulk-enhancing fibers having a three-dimensional anfractuous character may be provided. The ply is embossed to an emboss depth of at least about 0.020 inch, the percent loss in total dry breaking tensile strength upon embossing of the tissue being no more than about 80% of the percent loss in total dry breaking tensile strength upon embossing plies of a comparable conventional water formed tissue. The ply includes a basis weight of from about 4 to about 20 pound per 3,000 sq. ft. ream.
