Abstract

A fibrous structure. The structure includes a plurality of semi-continuous knuckles extending from portions of the surface of the fibrous structure in a parallel path, wherein the plurality of semi-continuous knuckles are separated by adjacent semi-continuous pillow regions. Each semi-continuous knuckle comprises a plurality of discrete pillows, the plurality of discrete pillows are arranged in a spaced configuration along the path of each of the semi-continuous knuckle.

Claims (17)
