Abstract: Single ply cellulose-based abrasive backers are provided that can include a saturated nonwoven web defining a first surface and a second surface, wherein the saturated nonwoven web comprises cellulosic fibers, synthetic fibers, and a cured saturant composition. About 80 wt % to about 100 wt % of the cellulosic fibers within the nonwoven web can be hardwood fibers. In most embodiments, a top coating is positioned on the first surface of the saturated nonwoven web. Optionally, a backside coating is positioned on the second surface of the saturated nonwoven web. Methods are also provided for forming a cellulose-based abrasive backer. Multi-ply cellulose-based abrasive backers are also provided.
