Abstract

The present invention is a liquid transport member with significantly improved liquid handling capability, which has at least one bulk or inner region with a high average permeability, completely circumscribed by a wall region. The wall region further comprises at least one port region with a lower permeability than the inner region, and with a ratio of its permeability to its thickness of at least 10 -7 m.
