Abstract

The present invention relates to cleansing articles comprising first and second members forming the first and second outer surface of the article respectively, where the coefficient of friction and/or permeability of the members are different. In certain embodiments the first member comprises a plurality of polymeric protuberances and the second member comprises a plurality of hollow projections.

First claim

What is claimed is:

1. A cleansing article comprising:
a) a first member comprising a nonwoven web having a first and a second side and a plurality of non-hollow polymeric protuberances disposed on the first side thereof, the first side forming the first outer surface of the cleansing article;
b) a second member comprising a nonwoven web having a first and a second side, the first side having a plurality of hollow projections substantially surrounded by a landing, the land areas lying in a first plane and the projections terminating at distal ends lying in a second plane, the first and second planes spaced apart a vertical distance from about 0.5 to about 1.5 mm, wherein the first side forms the second outer surface of the cleansing article; and
c) a core disposed between the first and the second members;

wherein the first outer surface has a coefficient of friction greater than 0.50 and the second outer surface has a coefficient of friction less than 0.50.

2. The cleansing article of claim 1 wherein the plurality of polymeric protuberances have an average height from about 300 to about 650 μm.

3. The cleansing article of claim 1 wherein the first outer surface has a coefficient of friction from about 0.75 to about 1.20 and the second outer surface has a coefficient of friction from about 0.35 to about 0.45.

4. The cleansing article of claim 1 wherein the plurality of polymeric protuberances have a substantially semi-spherical shape having an average volume from about 0.50 to about 0.70 mm 3 .

5. The cleansing article of claim 1 wherein the first outer surface has a surface area and the plurality of polymeric protuberances cover from about 5.0 to about 15.0 percent of the surface area.

6. The cleansing article of claim 1 wherein the first member has a permeability of 500 cfm or greater and the second member has a permeability less than 500 cfm.
