Abstract
A scouring pad is formed by disposing layers of a thermoplastic resin above and below a layer of metal wool. The resin and metal are compressed and heated to a temperature above the melting point of the resin. The resulting pad has mat-like upper and lower layers of metal fiber and resin, and an interior layer of metal fibers which is substantially free of the resin. The pad has a reduced tendency to shed metal fibers.
