Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
109 words
A scouring and cleaning cloth comprising a consolidated non-woven fabric composed of one of natural or synthetic fibers and having a coating of a solidified binding agent on at least a portion of each surface in an open pattern applied by a printing process, said pattern comprising superelevated bars so disposed with respect to one another to avoid a straight passage therethrough, the bars in at least one of the surfaces having embedded therein at least one of an abrasive and a soap additive, the non-woven fabric having a thickness sufficient to permit the printed surface portions to be pressed into the cloth to conform to a planar surface.
Claim 2
Dependent Claim
109 words
A scouring and cleaning cloth comprising a consolidated non-woven fabric composed of one of natural or synthetic fibers and having a coating of a solidified binding agent on at least a portion of each surface in an open pattern applied by a printing process, said pattern comprising superelevated bars so disposed with respect to one another to avoid a straight passage therethrough, the bars in at least one of the surfaces having embedded therein at least one of an abrasive and a soap additive, the non-woven fabric having a thickness sufficient to permit the printed surface portions to be pressed into the cloth to conform to a planar surface.
Claim 3
Dependent Claim
18 words
A scouring and cleaning cloth of claim 1, wherein a part of the bars has a non-rectilinear shape.
Claim 4
Dependent Claim
17 words
A scouring and cleaning cloth according to claim 2, wherein the non-rectilinear shape comprises an angular form.
Claim 5
Dependent Claim
27 words
A scouring and cleaning cloth of claim 1, wherein the sum of the individual surfaces covered by the bars is 10 to 50% of the total surface.
Claim 6
Dependent Claim
20 words
A scouring and cleaning cloth of claim 4, wherein the surface covered is 20 to 30% of the total surface.
Claim 7
Dependent Claim
25 words
A scouring and cleaning cloth according to claim 1, wherein the superelevated bars contain abrasive, and the abrasive-containing superelevated bars are on one surface only.
Claim 8
Dependent Claim
77 words
A scouring and cleaning cloth having a coating of a solid binding agent on at least a portion of each surface in an open pattern applied by a printing process, said pattern comprising superelevated bars, the bars in at least one of the surfaces having embedded therein at least one of an abrasive and a soap additive, the binding agent for the surface coating being a heat-sensitive polymer, comprising one of butadiene-acrylonitrile, a butadiene-styrene-latex, or a polyacrylate.
Claim 9
Dependent Claim
77 words
A scouring and cleaning cloth having a coating of a solid binding agent on at least a portion of each surface in an open pattern applied by a printing process, said pattern comprising superelevated bars, the bars in at least one of the surfaces having embedded therein at least one of an abrasive and a soap additive, the binding agent for the surface coating being a heat-sensitive polymer, comprising one of butadiene-acrylonitrile, a butadiene-styrene-latex, or a polyacrylate.
Claim 10
Dependent Claim
58 words
A scouring and cleaning cloth having a coating of a solid binding agent on at least a portion of each surface in an open pattern applied by a printing process, said pattern comprising superelevated bars, one surface being printed with a foamed binding agent dispersion and the other side being printed with an unfoamed, abrasive-containing binding agent dispersion.
Claim 11
Dependent Claim
58 words
A scouring and cleaning cloth having a coating of a solid binding agent on at least a portion of each surface in an open pattern applied by a printing process, said pattern comprising superelevated bars, one surface being printed with a foamed binding agent dispersion and the other side being printed with an unfoamed, abrasive-containing binding agent dispersion.
