Abstract: A nonwoven abrasive article comprises a lofty open nonwoven fiber web comprising entangled fibers. The fibers have an average diameter, and the fiber web has first and second opposed major surfaces and a porous interior therebetween. An abrasive material is predominantly disposed within the porous interior. The abrasive material comprises abrasive particles at least partially retained in a binder. The abrasive material comprises elongated blobs. Each elongated blob is respectively bonded to at least one of the fibers. The elongated blobs have a minimum width of at least two times the average diameter of the fibers, wherein a majority of the elongated blobs are longitudinally aligned within 40 degrees. The abrasive particles are magnetizable, the elongated blobs further comprise magnetizable particles different from the abrasive particles, or both. Methods of making the nonwoven abrasive article are also disclosed.

Abstract: Embodiments of sanding systems and methods for using and making the same may include providing a sanding system, comprising a body and a core. The body may be defined by at least a plurality of faces including a proximal face and a distal face and further defined by a hole extending lengthwise from the proximal face at least partially through the body toward the distal face. The core may be configured to be disposed at least partially within the hole such that changing an extent to which the core is disposed within the hole changes a density gradient of the sanding system.
