Abstract
The present invention is directed to enhancing the cleaning of surfaces by the contact application of a nonwoven fabric having a three-dimensional image imparted therein. The three-dimensional image of the 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.
Claims21
A nonwoven fabric for cleaning applications comprising;
- a) a precursor web;
- b) a three-dimensional image transfer device;
- c) hydroentangling said precursor web on said image transfer device to form an imaged nonwoven fabric having fibrous surface projections extending from a fibrous support plane and comprising at least 25% of the thickness of the overall support plane;
- and
- d) said fibrous surface projections are wave-like in form and form air passageways parallel to the fibrous support plane.
An imaged nonwoven fabric of claim 19, wherein the fabric has a basis weight within the range of about 3.0 to 4.0 ounces per square yard.
