Abstract
The present invention provides a disposable wiping article. The wiping article may be single-layer (single-ply), or multi-layer (multi-ply). At least one layer (the only layer in a single-layer wiping article) is a primary layer and is wet extensible. A discontinuous coating is applied to selected portions of the wet extensible primary layer and cured to form a constraining component which inhibits wet extension of the primary layer in the plane of the primary layer. As a result, the primary layer deforms, such as by buckling or puckering, in the Z-direction (perpendicular to the plane of the primary layer), resulting in increased caliper, bulk, and texture. In one embodiment, more than one primary layer may be used in a single wiping article.
