The two most common types of cloth used for pool tables are speed cloths and napped cloths. Speed cloths use polyester and contain a waterproofing agent which makes for an easier cleanup of liquid spills. It's typically more expensive as it enables a faster play of the ball and extends the quality of the cloth. Napped clothes, on the other hand, slows down the ball and requires more maintenance, but has a more affordable price tag suitable for standard play.
