Abstract

(see fig.I) The invention is a hook fastening material for use with a complementary loop fastening material, which hook fastening material has from about 1600 to about 2500 prongs per square inch and is substantially non-abrasive and non-irritating to human skin. In one embodiment the hook fastening material has prongs with an engaging means at an angle of about 90° to about 160° relative to the extension of the perpendicular to the plane of the substrate. In another embodiment the hook fastening material is formed on a compressible substrate. In still another embodiment the hook fastening material has prongs made of an ethylene vinyl acetate based polymer or a polyethylene based polymer. Methods for making such hook fastening materials and articles of use are also disclosed.
