Abstract
The present invention provides tissue products having an MD/CD Tensile Ratio less than about 0.95, yet relatively high geometric tensile strength, such as geometric mean tensile strengths greater than about 1500 g/3″ and more preferably greater than about 2000 g/3″. The combination of a tough, yet relatively supple sheet is preferably achieved by subjecting the embryonic web to a speed differential as it is passed from one fabric in the papermaking process to another, commonly referred to as rush transfer.
Claims18
A tissue product having an MD/CD Tensile Ratio less than 0.95, a basis weight from about 45 to about 80 grams per square meter (gsm) and a GMT from about 1500 to about 3500 g/3″.
A tissue product having an MD/CD Tensile Ratio less than about 0.95, a GMT from about 2200 to about 3500 g/3″ and a GM Stretch greater than about 22 percent.
A tissue product comprising cellulosic fibers and a wet strength agent selected from the group consisting of polyamide epichlorohydrin resins and glyoxalated polyacrylamide resins, the tissue product having an MD/CD Tensile Ratio less than about 0.95, a basis weight from about 40 to about 80 gsm, a GMT from about 1500 to about 3500 g/3″ and a GM TEA greater than about 40.0 g-cm/cm2.
