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.
Claims12
A method for producing a scouring pad, comprising:
- forming a layer of randomly oriented metal fibers;
- disposing a sheet of thermoplastic resin above and below said layer of metal fibers;
- and
- compressing said layer of metal fibers and said sheets of thermoplastic resin at a temperature above the melting point of said resin to form a scouring pad.
A scouring pad comprising distinct, matlike top and bottom layers of randomly oriented metal fibers, each of said layers held together by a thermoplastic resin bonding said fibers to one another, said thermoplastic resin covering the upper and lower surfaces of the pad and filling at least some of the spaces between said fibers;
- and
- an interior layer of randomly oriented metal fibers substantially free of said resin.
