Abstract

A fibrous structure and rolled tissue products of fibrous structures. The fibrous structures exhibit a plurality of discrete knuckles arranged in a pattern of repeat units. The discrete knuckles are characterized by each of the discrete knuckles within the repeat unit having substantially the same shape and substantially the same size. At least some of the discrete knuckles are arranged in a plurality of rows of adjacent knuckles separated by a distance, including at least a first row and a second row. The distance between at least two adjacent discrete knuckles in the first row is different than the distance between at least two adjacent discrete knuckles in the second row. The rolled tissue product exhibits a roll bulk of greater than 4 cm 3 /g or a percent compressibility of less than 10%.

First claim

1 . A rolled tissue product, the rolled tissue product comprising:
a. in rolled form, a fibrous structure, the fibrous structure exhibiting a plurality of discrete knuckles arranged in a pattern of repeat units in an X-Y coordinate plane, and characterized by:
i. each of the discrete knuckles within the repeat unit have substantially the same shape,
ii. each of the discrete knuckles within a repeat unit have substantially the same size; and,
iii. wherein at least some of the discrete knuckles are arranged in a plurality of rows of adjacent knuckles, the rows separated in a Y-direction a distance of between 0.020 inch and 0.200 inch, and including at least a first row and a second row, with an X-direction distance between at least two adjacent discrete knuckles in the first row being different than the X-direction distance between at least two adjacent discrete knuckles in the second row, the X-direction distance being between 0.010 inch and 0.100 inch; and,
b. the rolled tissue product exhibits a property selected from the group consisting of roll bulk of greater than 4 cm 3 /g and percent compressibility of less than 10%.

2 . The rolled tissue product of claim 1 , in which the rolled tissue product exhibits a roll bulk of greater than 4 cm 3 /g and a percent compressibility of less than 10 percent.

3 . The rolled tissue product of claim 1 , in which the rolled tissue product exhibits a roll bulk of greater than 6 cm 3 /g and a percent compressibility of less than 8 percent.

4 . The rolled tissue product of claim 1 , in which the rolled tissue product exhibits a roll bulk of greater than 8 cm 3 /g and a percent compressibility of less than 7 percent.

5 . The fibrous structure of claim 1 , wherein the fibrous structure comprises two plies.

6 . The fibrous structure of claim 1 , wherein the fibrous structure is embossed.

7 . The fibrous structure of claim 1 , wherein the fibrous structure is creped.

8 . The fibrous structure of claim 1 , wherein the fibrous structure is through air dried.

9 . The fibrous structure of claim 1 , wherein the fibrous structure is one of a paper towel or bath tissue.

10 . A package of a plurality of rolled tissue products, at least one of the plurality of rolled tissue products comprising:
a. in rolled form, a fibrous structure, the fibrous structure exhibiting a plurality of discrete knuckles arranged in a pattern of repeat units in an X-Y coordinate plane, and characterized by:
i. each of the discrete knuckles within the repeat unit have substantially the same shape,
ii. each of the discrete knuckles within a repeat unit have substantially the same size; and,
iii. wherein at least some of the discrete knuckles are arranged in a plurality of spaced apart rows of adjacent knuckles, the rows separated in a Y-direction by a distance of between 0.020 inch and 0.200 inch, and including at least a first row and a second row, with an X-direction distance between at least two adjacent discrete knuckles in the first row being different than the X-direction distance between at least two adjacent discrete knuckles in the second row, the X-direction distance being between 0.010 inch and 0.100 inch; and,
b. the rolled tissue product exhibits a property selected from the group of roll bulk of greater than 4 cm 3 /g and percent compressibility of less than 10%.

11 . The package of a plurality of rolled tissue products of claim 10 , in which the rolled tissue product exhibits a roll bulk of greater than 4 cm 3 /g and a percent compressibility of less than 10 percent.

12 . The package of a plurality of rolled tissue products of claim 10 , in which the rolled tissue product exhibits a roll bulk of greater than 6 cm 3 /g and a percent compressibility of less than 8 percent.

13 . The package of a plurality of rolled tissue products of claim 10 , in which the rolled tissue product exhibits a roll bulk of greater than 8 cm 3 /g and a percent compressibility of less than 7 percent.

14 . The package of a plurality of rolled tissue products of claim 10 , wherein the fibrous structure comprises two plies.

15 . The package of a plurality of rolled tissue products of claim 10 , wherein the fibrous structure is embossed.

16 . The package of a plurality of rolled tissue products of claim 10 , wherein the fibrous structure is creped.

17 . The package of a plurality of rolled tissue products of claim 10 , wherein the fibrous structure is through air dried.

18 . The package of a plurality of rolled tissue products of claim 10 , wherein the fibrous structure is one of a paper towel or bath tissue.

19 . A rolled tissue product, the rolled tissue product comprising:
a. in rolled form, a fibrous structure, the fibrous structure exhibiting a plurality of discrete knuckles arranged in a pattern of repeat units in an X-Y coordinate plane, and characterized by:
i. each of the discrete knuckles within the repeat unit have substantially the same shape,
ii. each of the discrete knuckles within a repeat unit have substantially the same size; and,
iii. wherein at least some of the discrete knuckles are arranged in a plurality of rows, the rows of adjacent knuckles separated in a Y-direction a distance of between 0.020 inch and 0.200 inch by a distance, and including at least a first row and a second row, with the distance between at least two adjacent discrete knuckles in the first row being different than the distance between at least two adjacent discrete knuckles in the second row, the X-direction distance being between 0.010 inch and 0.100 inch;
b. the fibrous structure has an absorbency rate of greater than 1.65 g/sec 1/2 and exhibits a property selected from the group consisting of roll bulk of greater than 4 cm 3 /g and percent compressibility of less than 10%.

20 . The rolled tissue product of claim 19 , in which the rolled tissue product exhibits a roll bulk of greater than 4 cm 3 /g and a percent compressibility of less than 10 percent.
