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.
