Various embodiments disclosed relate to an abrasive article. The abrasive article includes a nonwoven web. The non-woven web includes a first irregular major surface and an opposite second irregular major surface. The nonwoven web further includes a fiber component comprising staple fibers having a linear density ranging from about 50 denier to about 2000 denier and a crimp index value ranging from about 15% to about 60%. The nonwoven web further includes a binder dispensed on the fiber component and abrasive particles dispersed throughout the nonwoven web.

Large denier nonwoven fiber webs

A nonwoven abrasive article includes: a lofty open nonwoven fiber web, an abrasive layer bonded to the lofty open nonwoven fiber web, and a peripheral antiloading composition disposed on the abrasive layer. The peripheral antiloading composition comprises at least 50 percent by weight of wax having a melting point onset of from 180&#xb0; F. (82&#xb0; C.) to 290&#xb0; F. (143&#xb0; C.). A method of abrading a workpiece using the nonwoven abrasive article is also disclosed.

Nonwoven abrasive article with wax antiloading compound and method of using the same

A self-contained fibrous buffing article including at least one layer of a fibrous nonwoven fabric; the nonwoven fabric having a hardened adherent coating including a crosslinked binder, abrasive particles, and a lubricant blend; and the lubricant blend including at least a fatty acid, mineral oil and glycerin.

Self-contained fibrous buffing article

A molded abrasive brush having a backing with a plurality of bristles extending therefrom. The backing and bristles are preferably integrally molded. The brush is molded from a moldable polymer such a thermoset polymer, thermoplastic polymer, or thermoplastic elastomer. The moldable polymer includes a plurality of organic or inorganic abrasive particles interspersed throughout at least the bristles, and can be interspersed throughout the brush. The moldable brush can include an attaching means molded integrally with the backing. Also disclosed is a method of making a molded abrasive brush and a method of refining a workpiece surface with a molded abrasive brush.

Molded abrasive brush

A molded brush having a backing with a plurality of bristles extending therefrom. The backing and bristles are preferably integrally molded. The brush is molded from a moldable polymer such a thermoset polymer, thermoplastic polymer, or thermoplastic elastomer. The molded brush can include an attaching means molded integrally with the backing. Also disclosed is a method of making a molded brush and a method of refining a workpiece surface with a molded brush.

Molded brush

Bonded abrasive articles and methods of making and using same are presented, the bonded abrasive articles comprising abrasive particles dispersed throughout and adhered within an elastomeric polyurethane binder, at least a portion of the abrasive particles adhered to the polyurethane binder by a silane coupling agent. The silane coupling agent is preferably coated onto the abrasive particles before they are mixed with the uncured polyurethane resin. The articles of the invention exhibit excellent smear- and wear-resistance and provide improved abrasion efficiency.
