Abstract
A scrubbing article including a substrate and a texture layer. The texture layer is formed on at least one surface of the substrate, and is a solvent-free texture layer. The texture layer can include a plastisol ink or a hot melt adhesive, and may further include a plurality of ceramic microspheres. Methods of manufacture are also provided in which a solvent-free texture layer composition is applied to a substrate and then solidified to form a texture layer. In some non-limiting embodiments, the texture layer composition includes a hot melt adhesive and is applied to the substrate in the form of a wetted cellulose sponge.
