Abstract
A roller cover has a backing. A nap, which holds the paint, is attached to said backing. The nap further comprises threads for holding paint. The threads are agglomerated or connected to one another at the distal end of said threads. This produces the sponged on paint look when the roller is used to apply paint to a wall. The agglomerated or connected threads are produced by applying heat from a heat source such as a torch or hot plate, to a synthetic fiber.
