Tissue having high strength and low modulus
View Patent ↗The present invention provides tissue products having a high degree of stretch and low modulus at relatively high tensile strengths, 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.
1. A rolled tissue product comprising a tissue web spirally wound into a roll, the tissue web having an MD Slope less than about 5 kg/3″ and a GMT from about 2200 to about 3500 g/3″, the product having a Roll Firmness of less than about 7.0 mm.
2. The rolled tissue product of claim 1 wherein the tissue web has a percent MD Stretch greater than about 25 percent.
3. The rolled tissue product of claim 1 wherein the tissue web has a bone dry basis weight from about 40 to about 80 gsm.
4. The rolled tissue product of claim 1 wherein the tissue web is an uncreped through-air dried web.
5. The rolled tissue product of claim 1 wherein the tissue web comprises a single ply.
6. The rolled tissue product of claim 5 wherein the single ply web is a through-air dried web.
7. The rolled tissue product of claim 6 wherein the single ply web is an uncreped through-air dried web.
8. The rolled tissue product of claim 1 wherein the tissue web has a MD TEA greater than about 70 g*cm/cm 2 .
9. The rolled tissue product of claim 1 wherein the tissue web has a Stiffness Index less than about 5.0.
10. The rolled tissue product of claim 1 wherein the tissue web has a GMT from about 2500 to about 3500 g/3″.
11. The rolled tissue product of claim 1 wherein the tissue web has a GMT from about 2500 to about 2750 g/3″.
