Zusammenfassung:	A soft, fibrous material having excellent abrasion resistance and superior softness is made by relatively highly consolidating and then incrementally stretching a nonwoven material. The finished material is a nonwoven web having a plurality of discrete, spaced apart relatively high basis weight regions which are at least partially surrounded by at least one relatively low basis weight region. In one embodiment the soft, fibrous material is made from a nonwoven web having a consolidation area of at least about 30%, and the material has a bending rigidity (which correlates to softness) in a machine direction axis of bending of less than about 0.018 g.cm2/cm. In another embodiment, the soft, fibrous material is made from a nonwoven web having a consolidation area of at least about 30%, and the material has a fuzz removal value (which correlates to abrasion resistance) of less than about 0.30 mg/cm2.
