  • Patent number: 5128193
    Abstract: A fibrous structure comprising a batt of a loose assemblage of fibers, having an initial density, that is embossed to produce a batt having a discrete pattern of hydrogen-bonded, compressed or densified portions and regions between the compressed portions. The regions have an average density greater than the average initial density of the batt and less than the density of the batt and less than the density of the compressed portions so as to form discrete density gradients across the surface of the batt. The batt has an initial average density of from about 0.03g/cm.sup.3 to about 0.15 g/cm.sup.3. The compressed portions have an average density in the range of from about 0.40 g/cm.sup.3 to about 1.00 g/cm.sup.3 and have a size in the range of from about 0.0002 cm.sup.2 to about 0.12 cm.sup.2. The regions defined between the compressed portions occupy from about 97 percent to about 99.5 percent of the area of the surface of the batt.
