Unitary deflection member for making fibrous structures having increased surface area and process for making same

A unitary deflection member. The unitary deflection member can have a fluid pervious reinforcing member and a patterned framework. The patterned framework can have a plurality of regularly spaced protuberances extending from the reinforcing member. At least two of said protuberances can be similar in size and shape, and can have linear segments having different cross-sectional areas along the z-direction.

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.
