Fibrous structures
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.
1. A fibrous structure, comprising:
a plurality of discrete wet-formed knuckles extending from portions of a surface of the fibrous structure, wherein the plurality of discrete wet-formed knuckles are arranged in a pattern of repeat units in an X-Y coordinate plane, the repeat unit including a plurality of spaced apart rows, the rows separated in a Y-direction by a distance of between 0.020 inch and 0.200 inch, each row having a portion of the discrete wet-formed knuckles, and wherein the discrete wet-formed knuckles are characterized by:
each of the discrete wet-formed knuckles within the repeat unit have substantially the same shape,
at least two of the plurality of discrete wet-formed knuckles within the repeat unit have varying size; and
wherein the discrete wet-formed knuckles in each row are spaced from adjacent discrete wet-formed knuckles in an X-direction in a non-uniform manner such that the repeat unit exhibits varying pillow widths along the row, the X-direction distance being between 0.010 inch and 0.100 inch.
2. The fibrous structure of claim 1 , wherein the varying pillow widths vary in the X-direction from between about 0.030 inch to about 0.080 inch.
3. The fibrous structure of claim 1 , wherein the rows are non-linear.
4. The fibrous structure of claim 3 , wherein the rows are curved.
5. The fibrous structure of claim 4 , wherein the curved rows are curved in a sinusoidal pattern.
6. The fibrous structure of claim 1 , wherein all of the discrete wet-formed knuckles are in one of the plurality of spaced apart rows.
7. The fibrous structure of claim 1 , wherein all the rows are oriented along one of either a Y-axis or an X-axis.
8. The fibrous structure of claim 1 , wherein the fibrous structure comprises two plies.
9. The fibrous structure of claim 1 , wherein the fibrous structure is embossed.
10. The fibrous structure of claim 1 , wherein the fibrous structure is creped.
11. The fibrous structure of claim 1 , wherein the fibrous structure is through air dried.
12. The fibrous structure of claim 1 , wherein the fibrous structure is one of a paper towel or bath tissue.
13. A fibrous structure, comprising:
a plurality of discrete wet-formed knuckles arranged in a pattern of repeat units units in an X-Y coordinate plane, and characterized by:
each of the discrete wet-formed knuckles within the repeat unit have substantially the same shape,
at least two of the plurality of discrete wet-formed knuckles within the repeat unit have varying size; and
wherein at least some of the discrete wet-formed knuckles are arranged in a plurality of rows, the rows of adjacent wet-formed knuckles 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 wet-formed knuckles in the first row being different than the distance between at least two adjacent discrete wet-formed knuckles in the second row, the X-direction distance being between 0.010 inch and 0.100 inch, and wherein the rows are oriented along an X-axis which is at an angle between 1 degree and 25 degrees with respect to an MD direction of the fibrous structure.
14. The fibrous structure of claim 13 , wherein the varying pillow widths vary in the X direction from between about 0.030 inch to about 0.080 inch.
15. The fibrous structure of claim 13 , wherein the fibrous structure is one of a paper towel or bath tissue.
16. The fibrous structure of claim 13 , wherein the rows are non-linear.
17. The fibrous structure of claim 13 , wherein the rows are curved.
18. The fibrous structure of claim 13 , wherein the curved rows are curved in a sinusoidal pattern.
