First claim
Opening claim text (preview).
What is claimed is: 1 . A nonwoven article comprising a web of fibers and abrasive particles, the abrasive particles embedded in the web of fibers, wherein the abrasive particles have a mean solidity below about 0.85. 2 . The article according to claim 1 , wherein the nonwoven article is dry. 3 . The article according to claim 1 , wherein the abrasive particles have a mean solidity between about 0.3 and about 0.8. 4 . The article according to claim 1 , wherein the abrasive particles have a mean form factor between about 0.1 and about 0.6. 5 . The article according to claim 1 , wherein the abrasive particles have a mean ECD between about 20 and about 1000. 6 . The article according to claim 1 , wherein the abrasive particles have a mean Shore® D hardness between about 40 and about 90. 7 . The article according to claim 1 , comprising from about 0.1 to about 10 g of abrasive particles per square meter of the web of fibers. 8 . The article according to claim 1 , wherein at least about 50% of the abrasive particulate is degradable according to ASTM 6400D. 9 . The article according to claim 1 , wherein the nonwoven article is made of at least 2 superposing webs of fibers and the abrasive particles are located at the webs interfaces. 10 . The article according to claim 1 , wherein the particles are embedded within the web of fibers by needle punching of the web after deposition of the particles. 11 . The article according to claim 1 , wherein the mean ECD of the abrasive particles is from above about 5% to below about 100% of the thickness of the dry substrate. 12 . The article according to claim 1 , wherein the abrasive particles have a HV Vicker hardness from about 20 to about 100. 13 . The article according to claim 1 , wherein the abrasive particles comprise from about 0.1 to about 10 grams per square meter of the web of fibers. 14 . The article according to claim 1 , comprising between 2 and 4 webs of fibers.
