Abstract

The present invention provides an embossed multi-ply tissue product that is visually pleasing and has improved physical attributes. For example, the inventive multi-ply tissue products have reduced stiffness, such as a GM Flexural Rigidity less than about 600 mg*cm, improved absorbency, such as a Residual Water (WResidual) value less than about 0.15 g, and improved wet resiliency, such as a wet elastic strain ratio greater than about 32 percent.

First claim

What is claimed is:

1. An embossed multi-ply tissue product comprising a first through-air dried tissue ply and a second through-air dried tissue ply, the first and the second through-air dried tissue plies each comprising a permanent wet strength resin and the first through-air dried tissue ply having a first outer surface, an opposed second outer surface, a background pattern disposed on the first outer surface and a plurality of discrete, non-linear embossments disposed on the first outer surface, wherein the background pattern consists of a plurality of parallel, spaced apart line elements that are periodically intersected by the plurality of embossments, the product having a basis weight of at least about 40 grams per square meter (gsm) and a Drip Time (DT) greater than about 30 seconds.

2. The embossed multi-ply tissue product of claim 1 having a Residual Water (W Residual ) value from about 0.05 to about 0.15 g.

3. The embossed multi-ply tissue product of claim 1 having a Liquid Absorbed and Retained rate greater than about 94 percent.

4. The embossed multi-ply tissue product of claim 1 having a Fluid Discharge Weight (W D ) less than about 0.10 g.

5. The embossed multi-ply tissue product of claim 1 wherein the first and second through-air dried plies are uncreped.

6. The embossed multi-ply tissue product of claim 1 having a basis weight from about 40 to about 60 grams per square meter (gsm) and a geometric mean tensile (GMT) from about 2,000 to about 4,000 g/3″.

7. The embossed multi-ply tissue product of claim 1 having an embossed area less than about 10 percent.

8. The embossed multi-ply tissue product of claim 1 having a sheet bulk from about 15 to about 20 cubic centimeters per gram (cc/g).

9. The embossed multi-ply tissue product of claim 1 having a GMT greater than about 3,000 g/3″ and a Stiffness Index from about 3.0 to about 6.0.

10. A dripless tissue product comprising a first tissue ply and a second tissue ply, the first tissue ply having a first upper surface, a background pattern disposed on the first upper surface and a plurality of embossments disposed on the first upper surface, wherein the plurality of embossments intersect the background pattern and wherein the background pattern consists of a plurality of spaced apart, parallel line elements having a width from about 2.0 to about 6.0 mm and the embossments consist of discrete, non-linear elements and have an embossed area less than about 10 percent of area of the first upper surface, the tissue product having a basis weight from about 50 to about 60 gsm, a GMT from about 3,000 to about 4,000 g/3″ and a Fluid Discharge Weight (W D ) of less than 0.15 g.

11. The dripless tissue product of claim 10 having a Residual Water (W Residual ) value less than about 0.15 g.

12. The dripless tissue product of claim 10 having a Liquid Absorbed and Retained rate from about 94 to about 99 percent.

13. An embossed multi-ply tissue product having a first outer surface and an opposed second outer surface, the product comprising first and second through-air dried tissue plies, the first through-air dried tissue ply having a first surface which forms the first outer surface of the product, a background pattern consisting of a plurality of spaced apart, parallel line elements having a width from about 2.0 to about 6.0 mm disposed on the first outer surface of product and a first embossing pattern comprising discrete, non-linear line elements disposed on the first outer surface of product, wherein the embossing pattern intersects the background pattern and covers from about 5.0 to about 10.0 percent of the first outer surface of the tissue product, the product having a basis weight from about 50 to about 60 gsm, a GMT from about 3,000 to about 4,000 g/3″ and a Drip Time (DT) greater than about 30 seconds.

14. The embossed multi-ply tissue product of claim 13 having a Drip Time (DT) greater than about 45 seconds.

15. The embossed multi-ply tissue product of claim 13 having a Residual Water (W Residual ) value less than about 0.15 g.

16. The embossed multi-ply tissue product of claim 13 having a Liquid Absorbed and Retained rate greater than about 94 percent.

17. The embossed multi-ply tissue product of claim 13 having a Fluid Discharge Weight (W D ) less than 0.15 g.

18. The embossed multi-ply tissue product of claim 13 having a sheet bulk from about 15 to about 20 cubic centimeters per gram (cc/g).

19. The embossed multi-ply tissue product of claim 13 having a Stiffness Index from about 3.0 to about 6.0.

20. The embossed multi-ply tissue product of claim 13 wherein the discrete, non-linear line elements have an element length from about 20.0 to about 60.0 mm and a depth from about 500 to about 800 μm.

21. The embossed multi-ply tissue product of claim 13 wherein the embossed area comprises from 0.0 to about 1.0 percent dot embossments and from about 5.0 to about 10.0 percent discrete, non-linear line elements.
