CLAIMS:
What is claimed is:
1. A cleaning article comprising: a filler; and a netting wrapped around the filler, the netting comprising interwoven threads defining a plurality of openings, and having first and second opposed major surfaces; and an abrasive composite disposed on the first major surface, the abrasive composite comprising grit particles dispersed in an organic binder.
2. The cleaning article of claim 1, wherein the grit particles comprise organic grit particles.
3. The cleaning article of claim 2, wherein the organic grit particles comprise a polyolefin, polycarbonate, poly(meth)acylate, polyester, polyurea, melamine, or copolymer or blend thereof.
4. The cleaning article of claim any one of claims 1 - 3, wherein the grit particles are shaped particles.
5. The cleaning article of any one of claims 1 - 4, wherein the grit particles have a number average particle diameter of from 50 micrometers to 1000 micrometers.
6. The cleaning article of claim 5, wherein the grit particles have a number average particle diameter of from 150 micrometers to 400 micrometers.
7. The cleaning article of any one of claims 1 - 6, wherein the grit particles have a coating weight of from 10 gsm to 500 gsm.
8. The cleaning article of claim 7, wherein the grit particles have a coating weight of from 100 gsm to 300 gsm.
9. The cleaning article of any one of claims 1 - 8, wherein the grit particles are from 10 percent to 70 percent by weight relative to the overall weight of the abrasive composite.
10. The cleaning article of any one of claims 1 - 9, wherein the organic binder comprises a thermoset polymer.
11. The cleaning article of claim 10, wherein the thermoset polymer is made by polymerizing phenol formaldehyde, acrylate monomers, (meth)acrylated urethanes, (meth)acrylated epoxies, ethylenically-unsaturated free-radically polymerizable compounds, aminoplast derivatives having pendant alpha, beta-unsaturated carbonyl groups, isocyanurate derivatives having at least one pendant acrylate group, isocyanate derivatives having at least one pendant acrylate group) vinyl ethers, or mixture or combination thereof.
12. The cleaning article of any one of claims 1 - 11, wherein the netting, fdler, or both comprise a material that is biodegradable, recyclable, or made from a recycled material.
13. The cleaning article of any one of claims 1 - 12, wherein the fdler comprises a fibrous non-woven web.
14. The cleaning article of claim 13, wherein the fibrous non-woven web comprises an air-laid non-woven web, vertically lapped non-woven web, or combination thereof.
15. The cleaning article of claim 13 or 14, wherein the fibrous non-woven web comprises recycled polyester.
16. The cleaning article of any one of claims 1 - 15, wherein the filler comprises fibers having a denier of from 2 to 1000.
17. The cleaning article of any one of claims 1 - 16, wherein the filler has a density of from 10 kg/m3to 30 kg/m3.
18. A method of cleaning a substrate, the method comprising: scrubbing the cleaning article of any one of claims 1 - 17 against the substrate to remove a contaminant therefrom without visibly scratching the substrate.
19. The method of claim 18, wherein the substrate comprises a dish, utensil, glass, pot, pan, grill, wall, floor, countertop, or vehicle.
20. A method of making a cleaning article, the method comprising: providing a netting comprising interwoven threads defining a plurality of openings and having an exposed major surface; coating the exposed major surface with an abrasive composite slurry comprised of grit particles dispersed in an organic binder precursor; curing the organic binder precursor to obtain a cured abrasive composite; and wrapping and securing the netting around the filler to obtain the cleaning article whose outer surface comprises the cured abrasive composite.
