Absorbent tissue
View Patent ↗The present disclosure offers an improvement in papermaking methods and products, by providing a tissue sheet and a method to obtain a tissue sheet, with improved absorbency at a given basis weight. Thus, by way of example, the present disclosure provides a single ply tissue sheet having a basis weight greater than about 50 gsm and a specific vertical absorbent capacity greater than about 6.0 g/g.
1. A wet-laid tissue product having a geometric mean tensile (GMT) from about 2000 to about 3500 g/3″, a geometric mean slope (GM Slope) less than about 10.0 kg and a specific vertical absorbent capacity of 6.0 g/g or greater.
2. The tissue product of claim 1 having a GMT from about 2200 to about 3500 g/3″.
3. The tissue product of claim 1 having a GM Slope from about 6.0 to about 8.0 kg.
4. The tissue product of claim 1 having a Stiffness Index less than about 5.0.
5. The tissue product of claim 1 having a MD Stretch greater than about 30 percent.
6. The tissue product of claim 1 wherein the bone dry basis weight is from about 50 to about 70 grams per square meter (gsm).
7. The tissue product of claim 1 having a sheet bulk from about 10 to about 12 cc/g.
8. The tissue product of claim 1 spirally wound into a roll, the roll having a Roll Firmness less than about 10.0 mm.
9. The tissue product of claim 8 wherein the spirally wound roll has a Roll Firmness from about 6.0 to about 8.0 mm.
10. The tissue product of claim 1 wherein the sheet is a through-air dried sheet.
11. The tissue product of claim 1 wherein the sheet is an uncreped through-air dried sheet.
12. A wet-laid tissue product having a geometric mean tensile (GMT) from about 2500 to about 2750 g/3″, a basis weight from about 60 to about 70 gsm, a sheet bulk from about 10 to about 12 cc/g and a specific vertical absorbent capacity of 6.0 g/g or greater.
13. The tissue product of claim 12 having a MD TEA greater than about 50 g*cm/cm2 and a GM Slope less than about 10.0 kg.
14. The tissue product of claim 12 having a Stiffness Index less than about 5.0.
15. The tissue product of claim 12 having a MD Stretch greater than about 30 percent.
16. The tissue product of claim 12 wherein the product comprises a single ply tissue web.
17. The tissue product of claim 16 wherein the single ply web is a through-air dried web.
18. The tissue product of claim 16 spirally wound into a roll, the roll having a Roll Firmness from about 6.0 to about 8.0 mm.
19. The tissue product of claim 16 having a Stiffness Index less than about 5.0 and a specific vertical absorbent capacity from 6.0 g/g to about 7.0 g/g.
20. The tissue product of claim 16 having a basis weight from about 65 to about 70 gsm.
