摘要： A method for manufacturing a foraminous abrasive article whereby abrasive particles are concentrated in an external surface region of a foraminous substrate. The method includes the steps of: providing a foamable, hardenable, liquid resin composition and a foraminous substrate having an external surface; foaming the resin composition effective to disperse a plurality of gas bubbles throughout the resin composition; applying the foamed resin composition to the external surface of the substrate to form a foam coating layer having an upper surface; applying a plurality of abrasive particles to the upper surface of the foam coating layer; heating the foamed coating layer effective to eliminate the gas bubbles from the foamed coating layer; and hardening the resin composition to attach the abrasive particles to the substrate. The invention also concerns the foraminous abrasive article products of this method.

摘要： Lofty, low density nonwoven pads and a process for the manufacture of such pads are described. The pads of the invention each comprise a bundle of discontinuous fibers bonded to one another at their mutual points of contact. The fibers are arranged within the bundle to provide a dense longitudinal central portion extending to opposite ends of the bundle, less dense side portions, a longitudinal tensile strength and a transverse tensile strength, wherein the longitudinal tensile strength is greater than the transverse tensile strength. The pads are made according to a process comprising forming a tow of discontinuous fibers so that the fibers are arranged within the tow to extend along a first axis, twisting the tow along the first axis to form a slubbed tow, bonding the fibers to one another at their mutual contact points and cutting the slubbed tow into scouring pads and the like.

摘要： Abrasive articles, and methods of making abrasive articles by using a laser to convert (e.g., cut) at least a portion of the abrasive coating to form the abrasive article. The method includes laser propagation impinging on the abrasive back side (opposite the abrasive coating) and progressing through to the abrasive side. Such a process inhibits ridging effects around cut regions (e.g., openings) on the front side.
