Abstract
A pad which can be abrasive, scouring or both, is formed as a block of foam between two nonwovens. The foam is a polyurethane foam and the nonwovens are based on a mixture of polyamide and polyester fibers. The polyamide fibers have physical properties similar to those of the polyurethane foam. The nonwovens and the foam block are bonded together at their periphery by thermal-welding. The pad can be coated with abrasive fillers. It can also be used for scouring delicate surfaces when it contains little or no abrasive fillers.
