Abstract:
In some examples, an abrasive particle transfer system including a production tool including a dispensing surface with a plurality of cavities formed therein; abrasive particles removably disposed within at least some of the cavities; and a nonwoven substrate having an outer surface opposing the dispensing surface of the production tool, wherein the dispending surface of the production tool is configured to apply a compressive force to the outer surface of the nonwoven substrate to compress the nonwoven substrate from a first thickness to a second thickness, wherein, while the nonwoven substrate is compressed to the second thickness by the production tool, the abrasive particles are transferred from the plurality of cavities to the nonwoven substrate.
