Abstract

Products having improved handfeel and methods for making those products are described. The disclosed napkin product includes an emboss pattern that creates a pillow effect resulting in improved handfeel.

First claim

What is claimed is:

1. A napkin product comprising:
a base sheet produced by conventional wet pressing comprising an emboss pattern that is across at least about 50% of the napkin product;
wherein the emboss pattern comprises a series of emboss elements comprising petal-elements;
wherein two petal elements from adjacent emboss elements together form one side of a pillow zone;
wherein the pair of petal elements forming the side of the pillow zone are separated by a distance from about 0.005 inches to about 0.050 inches;
wherein the ratio between the length of the side of the pillow zone, measured from the center of the emboss elements, and the separation distance between the adjacent petal elements is from about 2:1 to about 60:1; and
wherein the embossed base sheet has a caliper of from at least about 85 to about 105 mils/8 sheets.

2. The napkin product of claim 1 , wherein the ratio between the length of the side of the pillow zone and the distance between the adjacent petal elements is from about 5:1 to about 10:1.

3. The napkin product of claim 1 , wherein each emboss element comprises four petal-elements.

4. The napkin product of claim 3 , wherein the four petal-elements are set at a 90° angle to one another.

5. The napkin product of claim 3 , wherein the emboss pattern comprises at least about 20 emboss elements per square inch.

6. The napkin product of claim 1 , wherein the emboss pattern is symmetrical.

7. The napkin product of claim 1 , wherein the emboss pattern is iterated.

8. The napkin product of claim 1 , wherein the emboss pattern is continuous.

9. The napkin product of claim 1 , wherein the emboss pattern is repetitive.

10. The napkin product of claim 1 , wherein at least one petal-element comprises a petal emboss.

11. The napkin product of claim 1 , wherein the basis weight is at least about 17.5 lbs/300 sq. ft.

12. The napkin product of claim 1 , wherein the base sheet is folded in half to form the napkin product.

13. The napkin product of claim 1 , wherein the base sheet is folded in quarters to form the napkin product.

14. The napkin product of claim 1 , wherein the wet tensile is at least about 145 gms/3″.

15. A napkin product comprising:
a base sheet produced by conventional wet pressing having a basis weight of at least about 17.5 lbs/3000 ft 2 ;
wherein the base sheet is embossed with a pattern comprising at least about 20 elements per in 2 ,
wherein each element comprises four petal-elements;
wherein each petal-element comprises a petal emboss that forms a pillow zone;
wherein the embossed base sheet has a caliper of from about 85 to about 105 mils/8 sheets; and
wherein the base sheet is folded in half or into quarters to form the napkin product.

16. A napkin product comprising:
a base sheet produced by conventional wet pressing comprising an emboss pattern;
wherein the emboss pattern comprises a series of emboss elements forming a pillow zone;
wherein the emboss elements that form one side of the pillow zone also form one side of the adjacent pillow zone;
wherein the emboss elements that form the side of the pillow zone comprise an interruption of from about 0.005 inches to about 0.050 inches that remains unembossed space; and
wherein the embossed base sheet has a caliper of from about 85 to about 105 mils/8 sheets.
