What is claimed is:
1. A scrubbing cloth comprising:
a substrate having a first surface and a second surface opposite the first surface; wherein the first surface has a first degree of loftiness and the second surface has a second degree of loftiness; and
wherein the first degree of loftiness is greater than the second degree of loftiness; and
wherein at least one of the first and second surfaces include a texture layer formed thereon.
2. The scrubbing cloth of claim 1, wherein the first surface has a first height and a first density and the second surface has a second height and a second density and wherein the first height is greater than the second height and the second density is greater than the first density.
3. The scrubbing cloth of claim 1, wherein the substrate consists essentially of a single layer of material.
4. The scrubbing cloth of claim 1, wherein each of the first and second surfaces comprise a texture layer.
5. The scrubbing cloth of claim 1, wherein the second surface comprises a consolidated surface.
6. The scrubbing cloth of claim 5, wherein the consolidated surface is formed by application of heat and pressure to the second surface.
7. The scrubbing cloth of claim 1, wherein the substrate comprises a fabric selected from the group consisting of a woven, a nonwoven, and a knit.
8. The scrubbing cloth of claim 1, wherein the substrate comprises a knit fabric formed by a knit stitch having loops configured such that the loops project from a plane of the fabric at the first surface and the loops lie substantially in a plane of the fabric at the second surface.
9. The scrubbing cloth of claim 1, wherein the texture layer defines a pattern.
10. The scrubbing cloth of claim 9, wherein the pattern includes a plurality of discrete segments.
11. The scrubbing cloth of claim 10, wherein the discrete segments include at least one of series of unconnected lines, dots or images.
12. The scrubbing cloth of claim 1, wherein the texture layer includes a multiplicity of ceramic microparticles.
13. The scrubbing cloth of claim 1, wherein the texture layer includes a plurality of randomly distributed texturings.
14. The scrubbing cloth of claim 1, wherein the texture layer comprises one of an e- beam or UV treated texture layer.
15. The scrubbing cloth of claim 1, further wherein at least one of the texture layer and substrate comprise a chemical solution for cleaning.
16. The scrubbing cloth of claim 1, wherein the texture layer comprises a hardness that is equal or greater than a hardness of the substrate.
17. A scrubbing cloth comprising:
a substrate having first and second surface opposed surfaces;
wherein at least one of the first and second surfaces is more absorptive than the other; and
wherein at least one of the first and second surfaces include a texture layer formed thereon.
18. A method of manufacturing a scrubbing cloth having a textured surface, the method comprising:
providing a scrubbing cloth having a first surface and a second surface opposite the first surface;
treating at least one surface of the cloth such that at least one of the surfaces includes at least one of an absorption, density, loftiness or height greater than the opposed surface;
allowing the first surface to remain undisturbed during the treating step; and forming a texture layer on at least one of the first and second surfaces.
19. The method of claim 18, wherein the texture layer comprises a soap solution.
