ABSTRACT:
A web-making fabric for producing a high caliper fibrous web and the fibrous web produced thereby. The web-making fabric comprises a reinforcing structure and a framework joined to the reinforcing structure. The framework defines a plurality of deflection conduits, at least one deflection conduit is a negatively radiused deflection conduit, and at least one deflection conduit is a positively radiused deflection conduit. The positively radiused deflection conduits are sized, shaped, and arranged to maximize fiber deflection along the periphery of the conduits. The web comprises three regions, a first region a second region and a third region. The first region is immediately adjacent to at least one of the second region and the third region. The second region comprises a plurality of negatively radiused domes. The third region comprises a plurality of positively radiused domes.
