Systems and methods include providing a coated abrasive article with a substrate formed from a plurality of hygroscopic fibers, an abrasive layer comprising a make coat, a size coat, a supersize coat, or combinations thereof disposed on a first side of substrate, and an anti-curl layer disposed on a second side of the substrate. The polymer-based anti-curl layer allows the coated abrasive article to achieve a change in curl between −5 millimeters and 25 millimeters, the change in curl being expressed as the curl of the coated abrasive article in millimeters at 90% relative humidity minus the curl of the coated abrasive article in millimeters at 20% relative humidity. The coated abrasive article exhibits substantially no loss of grinding performance, burst speed, or a combination thereof as compared to coated abrasive articles free of the anti-curl layer.
