Abstract

Paper products, such as wiping products, are disclosed that have a fabric-imprinted pattern in combination with a crepe pattern. In producing paper products according to the invention, a base web containing pulp fibers is formed. Once the base web is substantially dry, the web is creped to form a first pattern. The creped web is then placed between two moving conveyors and guided around one or more compression inducing elements. As the web is guided around the compression inducing element in between the two conveyors, shear forces and compressive forces are imparted to the web that form a fabric-imprinted pattern superimposed on the crepe pattern. In one embodiment, the fabric-imprinted pattern comprises high density troughs.

Claims (33)

1. A paper product comprising:

a creped nonwoven base web comprising a first side and a second side, said base web containing pulp fibers;

a crepe pattern formed on said base web; and

a first fabric-imprinted pattern, wherein said first fabric-imprinted pattern is superimposed upon said crepe pattern on said first side of said base web, said first fabric-imprinted pattern comprising high density troughs that extend in a machine direction, wherein said high density troughs are separated by about 3 mm to about 4 mm.

2. A paper product as defined in claim 1 , wherein said base web has a second fabric-imprinted pattern superimposed upon said crepe pattern on said second side of said base web, said second fabric-imprinted pattern comprising high density troughs.

3. A paper product as defined in claim 1 , wherein said base web has a basis weight of greater than about 20 gsm.

4. A paper product as defined in claim 1 , wherein said paper product comprises a single-ply product.

5. A paper product as defined in claim 1 , wherein said paper product comprises a stratified web.

6. A paper product as defined in claim 1 , wherein said base web has a geometric mean tensile strength of greater than about 200 g/in.

7. A paper product as defined in claim 1 , wherein said base web has a geometric mean tensile strength of greater than about 250 g/in.

8. A paper product as defined in claim 1 , wherein said base web has a bulk greater than about 7.5 cc/gram.

9. A paper product as defined in claim 1 , wherein said base web has a bulk greater than about 8.5 cc/gram.

10. A paper product as defined in claim 1 , wherein said base web has a caliper greater than about 250 microns.

11. A paper product as defined in claim 1 , wherein said base web has a caliper greater than about 275 microns.

12. A soft tissue comprising:

a creped nonwoven base web comprising a first side and a second side, said base web containing pulp fibers;

a crepe pattern formed on said base web;

a first fabric-imprinted pattern, wherein said first fabric-imprinted pattern is superimposed upon said crepe pattern on said first side of said base web, said first fabric-imprinted pattern comprising high density troughs that extend in either a machine direction or a diagonal direction, wherein said high density troughs are separated by about 3 mm to about 4 mm in the machine direction, and wherein said high density troughs are separated by about 2 mm to about 3 mm in the diagonal direction; and

wherein said soft tissue has a caliper greater than about 250 microns.

13. A soft tissue as defined in claim 12 , wherein said base web has a second fabric-imprinted pattern superimposed upon said crepe pattern on said second side of said base web, said second fabric-imprinted pattern comprising high density troughs.

14. A soft tissue as defined in claim 12 , wherein said base web has a basis weight between about 5 gsm and about 40 gsm.

15. A soft tissue as defined in claim 12 , wherein said tissue comprises a single-ply tissue.

16. A soft tissue as defined in claim 12 , wherein said base web comprises a stratified web.

17. A soft tissue as defined in claim 12 , wherein said tissue has a geometric mean tensile strength of greater than about 200 g/in.

18. A soft tissue as defined in claim 12 , wherein said tissue has a geometric mean tensile strength of greater than about 250 g/in.

19. A soft tissue as defined in claim 12 , wherein said tissue has a bulk greater than about 7.5 cc/gram.

20. A soft tissue as defined in claim 12 , wherein said tissue has a bulk greater than about 8.5 cc/gram.

21. A soft tissue as defined in claim 12 , wherein said tissue has a caliper greater than about 275 microns.

22. A paper product comprising:

a creped nonwoven base web comprising a first side and a second side, said base web containing pulp fibers;

a crepe pattern formed on said base web; and

a first fabric-imprinted pattern, wherein said first fabric-imprinted pattern is superimposed upon said crepe pattern on said first side of said base web, said first fabric-imprinted pattern comprising high density troughs that extend in a machine direction and in a diagonal direction; and

wherein said base web has a bulk greater than about 8.5 cc/gram, a caliper greater than about 250 microns, and a geometric mean tensile strength of greater than about 250 g/in.
