资源简介：
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.
