Abstract:
A sculpted fabric for the manufacture of a tissue web, having a tissue machine contacting side and a tissue contacting side, and comprising, on the tissue contacting side an upper porous member comprising a base with nonwoven elevated regions thereon comprising a first group of nonwoven raised elements and a second group of nonwoven raised elements, both raised relative to the base, wherein the first group of nonwoven raised elements extends in at least a first direction and the second group of nonwoven raised elements extends in at least a second direction, wherein the first and second groups of nonwoven raised elements are arranged on the base to produce elevated and depressed regions defining a three-dimensional tissue contacting surface comprising:a) a first background region having a set of substantially parallel first elevated regions comprising at least a subset of the first group of nonwoven raised elements, and comprising a first group of depressed regions, wherein the first elevated regions and the first depressed regions alternate; b) a second background region having a set of substantially parallel second elevated regions comprising at least a subset of the second group of nonwoven raised elements, and comprising a second group of depressed regions, wherein the second elevated regions and the second depressed regions alternate; and, c) a transition region positioned between the first and second background regions, wherein the first elevated regions of the first background region terminate and the second elevated regions of the second background region terminate.
