Tissue having high strength and low modulus
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 single ply tissue product having a Geometric Mean Tensile Strength (GMT) from about 2,200 to about 3,500 g/3″, a Geometric Mean Slope (GM Slope) less than about 10 kg/3″ and a Geometric Mean Stretch (GM Stretch) from about 15 to about 25 percent.
2. The single ply tissue product of claim 1 having a basis weight from about 35 to about 70 gsm.
3. The single ply tissue product of claim 1 having a basis weight from about 50 to about 70 gsm.
4. The single ply tissue product of claim 1 having a GM Stretch from about 18 to about 22 percent.
5. The single ply tissue product of claim 1 having a MD Stretch from about 45 to about 55 percent.
6. The single ply tissue product of claim 1 having a Machine Direction Tensile Energy Absorption (MD TEA) greater than about 45 g*cm/cm 2 .
7. The single ply tissue product of claim 1 having a GM Slope from about 4.0 to about 7.5.
8. The single ply tissue product of claim 1 having a GM Slope from about 4.0 to about 7.5 and a MD TEA from about 40 to about 100 g*cm/cm 2 .
9. The single ply tissue product of claim 1 wherein the tissue product is through-air dried.
10. The single ply tissue product of claim 1 wherein the tissue product is uncreped.
