Abstract
A laterally-stretched netting comprising a patterned abrasive layer on a first major surface thereof, and methods of making.
Claims16
A method of making a laterally-stretched netting comprising a patterned abrasive layer on a first major surface thereof, the method comprising the steps of, in order:
- providing a netting comprising a lateral width and comprising a first set of polymer strands and a second set of polymer strands, polymer strands of the first set being bonded to polymer strands of the second set at bond regions, and the first and second sets of strands comprising first surfaces that collectively define a first major surface of the netting;
- coating a make coat layer onto the first major surface of the netting so that at least some first surfaces of strands of the first set of strands, and some first surfaces of strands of the second set of strands, are make-coated strands;
- depositing abrasive particles onto at least some of the make-coated first surfaces of strands that define the first major surface of the netting, in a pre-determined pattern;
- laterally stretching the netting by a stretching factor of at least about 25%;
- and,
- hardening the make coat layer;
- whereby at least a majority of the abrasive particles are each singly bonded to a strand of the laterally-stretched netting.
