Abstract

The present invention provides a wet-wipe comprising a non-woven composite elastic material comprising a non-woven elastic layer; and a non-woven gatherable layer. The gatherable layer is bonded to the elastic layer at at least two points; and is gathered between the bonded points. These wet-wipes have a softer more cloth like feel.

Claims (48)

1. A wet-wipe comprising a non-woven composite elastic material comprising:

at least one non-woven elastic layer;

at least one non-woven gatherable layer;

wherein the gatherable layer is bonded to the elastic layer at at least two points; and the gatherable layer is gathered between the bonded points; wherein the composite elastic material has a cup crush less than about 120 g per cubic cm and has a CD tensile strength of greater than about 0.68 pounds; and a liquid.

2. A wet-wipe comprising a non-woven composite elastic material comprising:

at least one non-woven elastic layer;

at least one non-woven gatherable layer;

wherein the gatherable layer is bonded to the elastic layer at at least two points; and the gatherable layer is gathered between the bonded points; wherein the composite material has a cup crush to density ratio of less than about 1579 cm 2 and greater than about 950 cm 2 ; and a liquid.

3. A wet-wipe according to claim 1 or 2 , wherein the elastic layer is selected form the group consisting of an elastic film, an elastic web, elastic fibers and any combination thereof.

4. The wet-wipe according to claim 3 , wherein the elastic layer comprises an elastic web.

5. The wet-wipe according to claim 3 , wherein the elastic layer comprises elastic fibers.

6. The wet-wipe according to claim 3 , wherein the elastic layer comprises elastic fibers and a non-woven web.

7. The wet-wipe according to claim 6 , wherein the elastic fibers comprise polyethylene.

8. The wet-wipe of claim 6 , wherein the elastic fibers are substantially parallel.

9. The wet-wipe of claim 8 , wherein the substantially parallel elastomeric filaments are autogenously bonded to at least a portion of the web fibers.

10. The wet-wipe of claim 6 , wherein the elastic fibers are embedded in the web.

11. The wet-wipe according to claims 1 , or 2 , wherein the gatherable layer is a composite material.

12. The wet-wipe according to claim 7 , wherein the gatherable layer is coform.

13. The wet-wipe of claim 11 , the gatherable layer comprises polypropylene.

14. The wet-wipe of claim 11 , wherein the gatherable layer is non-elastic.

15. A wet-wipe according to claim 2 , wherein the composite material has a cup crush to density ratio of less than about 1400 cm 2 and greater than about 1100.

16. A wet-wipe according to claim 15 , wherein the composite material has a cup crush to density ratio of less than about 1300 cm 2 and greater than about 1100.

17. The wet-wipe according to claim 2 , wherein the material has a cup crush less than about 120 g cm.

18. The wet-wipe of claim 1 or 17 , having a cup crush less than about 110 g cm.

19. The wet-wipe of claim 18 , having a cup crush less than about 90 g cm.

20. The wet-wipe of claim 19 , having a cup crush less than about 70 g cm.

21. The wet-wipe according to claim 1 , wherein the material has a density less than about 0.085 g per cubic cm.

22. The wet-wipe of claims 1 or 21 , wherein the material has a density less than about 0.075 g per cubic cm.

23. The wet-wipe of claims 22 , wherein the material has a density less than about 0.060 g per cubic cm.

24. The wet-wipe of claims 1 , wherein the material has a CD tensile strength of greater than about 0.75 pounds.

25. The wet-wipe of claim 24 , wherein the material has a CD tensile strength of greater than about 0.80 pounds.

26. The wet-wipe of claim 25 , wherein the material has a CD tensile strength of greater than about 0.90 pounds.

27. The wet-wipe of claim 1 or 2 , wherein the basis weight of the composite elastic material is from about 75 to about 90 grams per square meter.

28. The wet-wipe of claim 27 , wherein the basis weight of the composite elastic material is about 85 grams per square meter.

29. The wet-wipe of claim 27 , wherein the composite elastic material comprises

a) an elastic layer comprising elastic fibers bound to a elastic web; and

b) two gatherable layers comprising coform;

wherein the elastic layer is positioned between the two gatherable layers.

30. The wet wipe of claim 1 or 2 , wherein the liquid is distributed within the layers; and the liquid comprises at least one material selected from the group of materials including preservatives, fragrances, emollients, humectants, detergents and soaps.

31. A wet-wipe comprising:

a non-woven composite material comprising fibers and a polymer; wherein the composite material has a cup crush less than about 120 g per cm and a CD tensile strength of greater than about 0.68 pounds; and a liquid.

32. A wet-wipe comprising:

a non-woven composite material comprising fibers and a polymer; wherein the composite material has a cup crush density ratio of less than about 1579 cm 2 and greater than about 950 cm 2 ; and a liquid.

33. A wet-wipe comprising:

a non-woven composite material comprising fibers and a polymer; wherein the composite material has a cup crush to density ratio of less than about 1579 cm 2 and a CD tensile strength of greater than about 0.68 pounds; and a liquid.

34. A method for preparing a wet-wipe according to claim 1 or 2 , wherein the wet-wipe has at least one non-woven elastic layer; and at least one non-woven gatherable layer comprising bonding the elastic and gatherable layers at at least two points.

35. The wet-wipe according to claim 7 , wherein the gatherable layer comprises absorbent non-woven fibers.
