The substrate is a woven or non-woven fibrous web with first and second major surfaces, at least one of the major surfaces having formed thereon an array of projections, the array including from at least 2 to about 20 projections per cm². Each projection is formed of a material different than that of the substrate and is raised from the substrate at a highest point thereof a distance from 100 to 2,000 micron. The projections are formed of at least 20 microbeads per projection.
