Hand scouring pad










Image Number 2 for United States Patent #4991362.

A low-density nonwoven abrasive pad, especially suited for use as a scouring article, formed of a multiplicity of continuous, crimped thermoplastic organic filaments having one end of substantially all of the filaments bonded together at one end of the pad and the opposite end of substantially all of the filaments bonded together at the opposite end of the pad. The abrasive pad is made by arranging the filaments into an open lofty array, bonding substantially all of the filaments together at a first and second bond site, and then cutting the array at the bond sites such that each bond is divided into at least two bond area segments with each bond area segment having the filament array bonded therein in a unitary structure.
