1. An abrasive article, comprising:
- a nonwoven web of fibers bonded to one another, the fibers defining a first major web surface, a second major web surface and a middle web portion extending between the first and second major web surfaces, the fibers each having a surface and a length; and
a plurality of abrasive particles adhered to the surfaces of the fibers of at least one of the first or second major web surfaces and distributed along the lengths of the fibers in a substantially uniform and continuous manner and substantially protruding from the fibers of the web, the particles comprising a distribution of particle sizes having a median particle of about 60 microns or less.
