A consumer scrubbing wipe article including a nonwoven substrate and a texture layer. The nonwoven substrate has a dry basis weight of less than about 300 g/m2, and thus promotes easy, comfortable handling by a user. The texture layer is a non-crosslinked, abrasive resin-based material that is printed onto at least one surface of the nonwoven substrate. In this regard, the texture layer covers less than an entirety of the substrate surface and extends at least 50 microns outwardly beyond the substrate surface to which it is printed. This characteristic ensures that the scrubbing wipe article has a distinct scrubbyness attribute.

What is claimed is: 1. A consumer scrubbing wipe article comprising: a nonwoven substrate having a dry basis weight of less than about 300 g/m2; and a non-crosslinked, abrasive resin-based texture layer printed onto at least one surface of the substrate such that the texture layer extends at least
What is claimed is: 1. A consumer scrubbing wipe article comprising: a nonwoven substrate having a dry basis weight of less than about 300 g/m2; and a non-crosslinked, abrasive resin-based texture layer printed onto at least one surface of the substrate such that the texture layer extends at least 50 microns outwardly beyond the substrate surface upon coalescing; wherein the texture layer bonds to the surface of the substrate via coalescing, and includes resin characterized as independently imparting a scrubbyness attribute to the article upon coalescing and forms a discontinuous pattern that covers less than an entirety of the substrate surface, the pattern including a texture layer segment defined by a perimeter separating the texture layer segment from other portions of the texture layer such that a zone of non-texture layer surrounds the perimeter, and further wherein a cross-section of an entirety of the texture layer segment within the perimeter is a continuously solid structure. 2. A consumer scrubbing wipe article comprising: a nonwoven substrate having a dry basis weight of less than about 300 g/m2; and a non-crosslinked, abrasive resin-based texture layer printed onto at least one surface of the substrate such that the texture layer extends at least 50 microns outwardly beyond the substrate surface upon coalescing; wherein the texture layer bonds to the surface of the substrate via coalescing, and includes resin characterized as independently imparting a scrubbyness attribute to the article upon coalescing; and further wherein the texture layer includes a plurality of discrete, spaced regions that collectively cover less than an entirety of the substrate surface, an entirety of each region extending from the surface to a face defined by a perimeter, the face characterized by the absence of edges within the perimeter. 3.
