An attachable abrasive article according to claim 1, wherein the abrasive member comprises a coated abrasive member, the coated abrasive member comprising: a backing having first and second, opposed major surfaces; and an abrasive layer secured to at least a portion of the first major surface of the backing, wherein the attachment device is affixed to the second major surface of the backing. 13. An attachable abrasive article according to claim 12, wherein the backing comprises at least one of a foam or a sponge. 14. An attachable abrasive article according to claim 13, wherein the thermoplastic material contacts substantially the entire first major surface of the flange and the peripheral edge. 15. An attachable abrasive article according to claim 12, wherein the abrasive layer comprises a make layer having abrasive particles embedded therein and a size layer at least partially covering the make layer and abrasive particles. 16. An attachable abrasive article according to claim 12, wherein the fastener comprises a quick change fastener. 17. An attachable abrasive article according to claim 16, wherein the fastener is selected from the group consisting of a Tinnerman nut and a threaded post. 18. An attachable abrasive article according to claim 12, wherein the backing comprises fabric. 19. An attachable abrasive article according to claim 1, wherein the abrasive article comprises a surface conditioning member, the surface conditioning member having a lofty open low-density fibrous web formed of entangled filaments impregnated with binder resin, and abrasive particles dispersed throughout the fibrous web on exposed surfaces of the filaments, wherein the surface conditioning member has first and second opposed major surfaces, and wherein the attachment device is welded to the second major surface of the surface conditioning member. 20. An attachable abrasive article according to claim 19, wherein the thermoplastic material contacts substantially the entire first major surface of the flange and the peripheral edge. 21.
