I googled it... yes:
Hook-and-loop sandpaper has a backing made of a material similar to Velcro. It has hooks and loops that are used to attach the sandpaper to a machine such as a random orbital sander or disc sander. ... The pads have small plastic "hooks" that attach to the "loops" on the sanding discs
