Abstract: Abrasive articles including a nonwoven fibrous substrate having a plurality of fibers, and a multiplicity of shaped abrasive particles, each shaped abrasive particle adhered to a corresponding fiber, each shaped abrasive particle having a length (L) and a width (W) determined in a direction substantially orthogonal to the length, the ratio of the length to the width defining an aspect ratio (L/W) of at least 1.1, each abrasive particle is oriented relative to its corresponding fiber, and more than 50% of the abrasive particles are oriented with respect to their corresponding fiber such that the abrasive particle length extends generally outwardly away from a surface of the corresponding fiber as determined visually using the Orientation Test. The shaped abrasive particles may have the geometric shape of a polygonal prism having two faces and at least three sides thereon. Methods of making the abrasive articles are also disclosed.

Abstract: A coated abrasive disc includes a disc backing having an outer circumference. An abrasive layer is disposed on the disc backing. The abrasive layer comprises triangular abrasive platelets secured to a major surface of the disc backing by at least one binder material. The triangular abrasive platelets are outwardly disposed at regularly-spaced points along a spiral pattern extending outwardly toward the outer circumference. Each triangular abrasive platelet has respective top and bottom surfaces connected to each other, and separated by, three sidewalls. On a respective basis, one sidewall of at least 90 percent of the triangular abrasive platelets is disposed facing and proximate to the disc backing, and at least 70 percent of the triangular abrasive platelets are disposed in a recurring sequential orientation having an oscillating Z-axis rotational orientation of the first respective sidewall relative to the tangents to the spiral pattern at regularly-spaced points. Methods of making and using the coated abrasive disc are also disclosed.

Abstract: Grinding aid particles for abrasive articles. The grinding aid particles include a core particle having a Mohs hardness of less than 7 and a coating on at least a portion of the surface of the core. The coating comprises a binder and at least one grinding agent. The grinding aid particles can be incorporated in the make coat, size coat and/or supersize coat of an abrasive article to improve abrasive performance.
