Disposable cleaning sheets comprising a plurality of protrusions for removing debris from surfaces
First Claim
1. A disposable cleaning sheet comprising:
- i) a substrate; and
ii) a plurality of protrusions affixed to said substrate;
wherein the attractive force between a hair and a single protrusion of said cleaning sheet is greater than the binding force between said hair and a surface comprising fibers;
wherein the force between said cleaning sheet and said surface is less than the force required to move said cleaning sheet across said surface;
wherein the force between said cleaning sheet and said surface is less than the binding force holding together said fibers of said surface; and
wherein said surface is selected form the group consisting of;
carpet, rug, upholstery, fabric.

Abstract
Disposable cleaning sheets for removing debris from a surface comprise a substrate and a plurality of protrusions affixed to the substrate. The cleaning sheets of the present invention have one or more of the following characteristics: (a) “Protrusion Flexibility” of at least about 0.5 grams, preferably from about 1 to about 200 grams, and more preferably from about 5 to about 70 grams; (b) “Glide Resistance” of less than about 1200 grams, preferably from about 25 to about 950 grams, and more preferably from about 200 to about 750 grams; (c) “Hair Capture Efficiency” of at least about 10%, preferably at least about 30%, and more preferably at least about 60%; and/or (d) “Sheet Capacity” of from about 0.2 to about 20 grams, preferably from about 0.5 to about 10 grams, and more preferably from about 0.75 to about 5 grams. When the present cleaning sheet is attached to a cleaning implement, the Attachment Force between the cleaning sheet and the cleaning implement will typically be at least about 600 grams, preferably at least about 1000 grams, and more preferably at least about 1400 grams. Methods of removing debris from a surface comprise contacting the surface with a cleaning sheet of the present invention.

22. A cleaning implement for removing debris from a surface, said cleaning implement comprising:
-
iv) a handle and mophead comprising an attachment means; and
v) a disposable cleaning sheet removably attach to said attachment means of said mophead, said cleaning sheet comprising a) a substrate;
b) and a plurality of protrusions, affixed to said substrate wherein the attachment force between said attachment means and said cleaning sheet is greater than the peak load resistance to glide between said cleaning sheet and said surface as said cleaning sheet is moved across said surface, as measured by the Glide Resistance Test. - View Dependent Claims (23, 24, 25, 26, 27, 28)
