  • Patent number: 5571604
    Abstract: Disclosed is an adsorbent fibrous nonwoven structure composed of (1) a matrix of pulp fibers having a first exterior surface and a second exterior surface; and (2) an adsorbent material integrated into the pulp fiber matrix so that the concentration of adsorbent material adjacent the first exterior surface of the nonwoven structure is at least about 60 percent, as determined by optical image analysis, and the concentration of adsorbent material adjacent the second exterior surface is less than about 40 percent, as determined by optical image analysis. This adsorbent nonwoven structure provides useful strength and low-lint characteristics. The fibrous nonwoven structure of the present invention may be laminated together or to surfaces of other materials.
