Abstract
A fibrous web having a first surface and a second surface. The fibrous web has a first region and at least one discrete second region, the second region being a discontinuity on the second surface and being a tuft comprising a plurality of tufted fibers extending from the first surface. The tufted fibers define a distal portion, the distal portion comprising portions of the tufted fibers being bonded together. Bonding can be thermal melt-bonding. In another embodiment the second surface of the web can have non-intersecting or substantially continuous bonded regions, which also can be thermal melt-bonding.
