Elongate abrasive article with orientationally aligned formed abrasive particles

An abrasive article comprising at least one primary elongate abrasive element extending along an element axis, the primary elongate abrasive element comprising a plurality of formed abrasive particles retained in an organic binder that is a thermoplastic polymer, a thermoplastic elastomer, or a combination thereof and comprises no thermoset polymer, wherein the plurality of formed abrasive particles each comprise:

• a maximum dimension M;
• a thickness T measured perpendicularly to the maximum dimension M;
• a particle axis defined along the maximum dimension M;
• and
• a particle plane containing the particle axis and perpendicular to the thickness T;
• wherein at least 50% of the formed abrasive particles are orientationally aligned along the element axis, wherein the orientationally aligned formed abrasive particles comprise first and second major faces separated by the thickness T, wherein the particle axis is defined along one of the first major face or the second major face, and the particle plane is substantially parallel to the first and second major faces, and wherein the formed abrasive particles that are orientationally aligned are generally orientationally aligned such that the particle plane is oriented within 60 degrees of parallel to the element axis.
