Abstract

See full text

Disclosed is a cellulosic fibrous structure, such as paper. The fibrous structure has at least three intensively distinct regions. The regions are distinguished from one another by intensive properties such as basis weight, density and projected average pore size, or thickness. In one embodiment, the fibrous structure has regions of two basis weights, a high basis weight region and a low basis weight region. The high basis weight region is further subdivided into low and high density regions so that a fibrous structure having three regions is produced. A second embodiment is a four region fibrous structure. Two of the regions have generally equivalent relatively high basis weights and two of the regions having generally equivalent relatively low basis weights. The high basis weight regions and low basis weight regions are further subdivided according to relatively high and relatively low densities, so that when the high and low basis weight regions are permuted with the high and low density regions, four different regions result. The regions distinguished by density will have inversely proportionate projected average pore sizes.
