Abstract
The present invention is directed to enhancing the cleaning of surfaces by the contact application of a non-apertured nonwoven fabric having a three-dimensional image imparted therein. The three-dimensional image of the non-apertured nonwoven fabric induces the formation of lather due to pronounced surface projections that come in contact with the cleaning surface and provide air passageways that are parallel to the plane of the substrate. The imaged nonwoven fabric disclosed herein exhibits low linting qualities thereby reducing the potential of fiber contamination of the cleaned surface and is sufficiently durable that the sample can be used in a brisk manner.
