Abstract

A fibrous structure is disclosed. The fibrous structure exhibits a plurality of discrete knuckles arranged in a pattern of repeat units. The repeat units can include a plurality of rows arranged orthogonally in an X-Y plane, each row having a portion of the discrete knuckles, and each discrete knuckle separated from adjacent discrete knuckles in a row by a distance. Each of the discrete knuckles within the repeat unit can have substantially the same shape and size; and wherein the distance between at least two adjacent discrete knuckles in each row are non-uniform such that the repeat unit exhibits varying pillow width distances along the rows in both the X and Y axes.

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 extending from portions of the surface of the fibrous structure, wherein the plurality of discrete knuckles are arranged in a pattern of repeat units, the repeat unit including a plurality of rows arranged orthogonally in an X-Y plane, each row having a portion of the discrete knuckles, each discrete knuckle separated from adjacent discrete knuckles in a row by a distance of between 0.020 inch and 0.200 inch, and wherein the discrete knuckles are 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 the distance between at least two adjacent discrete knuckles in each row are non-uniform such that the repeat unit exhibits varying distances along the rows in both the X and Y axes with the distance in the Y-axis direction being between 0.020 inch and 0.200 inch and the distance in the X-direction being between about 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 extending from portions of the surface of the fibrous structure, wherein the plurality of discrete knuckles are arranged in a pattern of repeat units, the repeat unit including a plurality of rows arranged orthogonally in an X-Y plane, each row having a portion of the discrete knuckles, each discrete knuckle separated from adjacent discrete knuckles in a row by a distance of between 0.020 inch and 0.200 inch, and wherein the discrete knuckles are 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 the distance between at least two adjacent discrete knuckles in each row are non-uniform such that the repeat unit exhibits varying distances along the rows in both the X and Y axes with the distance in the Y-axis direction being between 0.020 inch and 0.200 inch and the distance in the X-direction being between about 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%.

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 extending from portions of the surface of the fibrous structure, wherein the plurality of discrete knuckles are arranged in a pattern of repeat units, the repeat unit including a plurality of rows arranged orthogonally in an X-Y plane, each row having a portion of the discrete knuckles, each discrete knuckle separated from adjacent discrete knuckles in a row by a distance of between 0.020 inch and 0.200 inch, and wherein the discrete knuckles are 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 the distance between at least two adjacent discrete knuckles in each row are non-uniform such that the repeat unit exhibits varying distances along the rows in both the X and Y axes with the distance in the Y-axis direction being between 0.020 inch and 0.200 inch and the distance in the X-direction being between about 0.010 inch and 0.100 inch; and,
