Abstract
Use of a textured polyester filament yarn in a substrate for the manufacture of abrasives is disclosed. The substrate permits the manufacture of abrasives having a uniform and clean surface and a long running time. Coated abrasives incorporating the invention will not rapidly lose their binding agent grain layer during grinding and possess a high level of adhesion between substrate and adhesive. The particular yarn disclosed exhibits good absorbency for a binding agent for all, including fine, grains of abrasives.
