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.
Claims20
A fibrous structure, comprising:
- a plurality of discrete wet-formed knuckles arranged in a pattern of repeat 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 curved rows of adjacent wet-formed knuckles, the curved rows separated in a Y-direction by a distance of between 0.020 inch and 0.200 inch, and including at least a first curved row and a second curved row, with an X-direction distance between at least two adjacent discrete wet-formed knuckles in the first curved row being different than an X-direction distance between at least two adjacent discrete wet-formed knuckles in the second curved row, the X-direction distances being between 0.010 inch and 0.100 inch.
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 curved rows, the curved rows separated in a Y-direction by a distance of between 0.020 inch and 0.200 inch, each curved 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 curved 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 curved row, the X-direction distance being between 0.010 inch and 0.100 inch.
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 curved rows oriented in an X-direction and a plurality of spaced apart curved rows oriented in a Y-direction, the curved rows oriented in the X-direction separated in the Y-direction by a distance of between 0.020 inch and 0.200 inch, and the curved rows oriented in the Y-direction separated in the X-direction, each curved 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 curved row oriented in the X-direction are spaced from adjacent discrete wet-formed knuckles in the X-direction in a non-uniform manner such that the repeat unit exhibits varying pillow widths along the curved row, the X-direction distance being between 0.010 inch and 0.100 inch.
