Abstract

A disposable tissue or paper towel product including at least two plies, an exposed outer surface of at least one of the two plies comprising a plurality of pockets, the plurality of pockets having an average volume greater than 0.4 mm3 and an average surface area of 2.5 mm2.

First claim

What is claimed is:

1. A disposable tissue or paper towel product comprising:
at least two plies, an exposed outer surface of at least one of the two plies having a surface area comprising a plurality of pockets, the plurality of pockets having an average volume greater than 0.4 mm 3 and an average surface area of 2.5 mm 2 ,
wherein the at least one of the two plies comprises embossments and the embossments provide an embossed area covering between 5 to 15 percent of the surface area.

2. The product of claim 1 , wherein the product is formed using a structured fabric of a through air dying process.

3. The product of claim 1 , wherein the product is formed using one of the following types of wet-laid forming processes: Through Air Drying (TAD), Uncreped Through Air Drying (UCTAD), Advanced Tissue Molding System (ATMOS), NTT, and ETAD.

4. The product of claim 1 , wherein the at least two plies are laminated together.

5. The product of claim 4 , wherein the at least two plies are laminated together with heated adhesive.

6. The product of claim 2 , wherein the structured fabric is made of warp and weft monofilament yarns.

7. The product of claim 6 , wherein the diameter of the warp monofilament yarn is 0.40 mm.

8. The product of claim 6 , wherein the diameter of the weft monofilament yarn is 0.550 mm.

9. The product of claim 6 , wherein the diameter of the warp monofilament yarn is 0.30 mm to 0.55 mm.

10. The product of claim 6 , wherein the diameter of the weft monofilament yarn is 0.30 to 0.55 mm.

11. The product of claim 2 , wherein the through air drying process comprises transferring a web that forms the at least one of the two plies from a forming wire to the structured fabric at a 5% speed differential or more.

12. A disposable tissue or paper towel product comprising:
at least two plies, an exposed outer surface of at least one of the two plies having a surface area comprising a plurality of pockets, the plurality of pockets having an average volume greater than 0.4 mm 3 and an average surface area of 2.5 mm 2 , the disposable tissue or paper towel product having a basis weight less than 45 gsm,

17. The product of claim 13 , wherein the structured fabric is made of warp and weft monofilament yarns.

18. The product of claim 17 , wherein the diameter of the warp monofilament yarn is 0.40 mm.

19. The product of claim 17 , wherein the diameter of the weft monofilament yarn is 0.550 mm.

20. The product of claim 17 , wherein the diameter of the warp monofilament yarn is 0.30 mm to 0.55 mm.

21. The product of claim 17 , wherein the diameter of the weft monofilament yarn is 0.30 to 0.55 mm.

22. The product of claim 13 , wherein the through air drying process comprises transferring a web that forms the at least one of the two plies from a forming wire to the structured fabric at a 5% speed differential or more.

23. A disposable tissue or paper towel product comprising:
at least two plies, an exposed outer surface of at least one of the two plies having a surface area comprising a plurality of pockets, the plurality of pockets having an average volume greater than 0.4 mm 3 , the disposable tissue or paper towel product having a basis weight less than 45 gsm,
wherein the at least one of the two plies comprises embossments and the embossments provide an embossed area covering between 5 to 15 percent of the surface area.

24. The product of claim 23 , wherein the product is formed using a structured fabric of a through air dying process.

25. The product of claim 23 , wherein the product is formed using one of the following types of wet-laid forming processes: Through Air Drying (TAD), Uncreped Through Air Drying (UCTAD), Advanced Tissue Molding System (ATMOS), NTT, and ETAD.

26. The product of claim 23 , wherein the at least two plies are laminated together.

27. The product of claim 26 , wherein the at least two plies are laminated together with heated adhesive.

28. A disposable tissue or paper towel product comprising:
at least two plies, an exposed outer surface of at least one of the two plies comprising a plurality of pockets, the plurality of pockets having an average volume greater than 0.4 mm 3 and an average surface area of 2.5 mm 2 ,
at least one of the two plies comprising embossments having a depth of 0.28 cm to 0.43 centimeters.
