ABSTRACT:
A composite scouring pad is prepared comprising a non-woven layer and a flexible foam layer in juxtaposition to each other, the flexible foam being needled to the nonwoven layer by fibers from the non-woven layer which pass through the foam layer and emerge from its opposite side. The opposite side of the foam layer is coated with a resinous layer which anchors the emergent fibers thereon, the fibers providing a desired roughness to said side, making said side suitable as a scouring surface. The non-woven layer is impregnated with a resin and, in the preferred embodiment, with abrasive particles to provide a second scouring surface.
