Abstract:
A liquid acquisition/distribution structure comprising:(1) a top layer that is permeable to a liquid, (2) a distribution layer comprising a capillary system of an essentially parallel bundle of synthetic fibers arranged so that in a region their axes are essentially parallel to said top layer, the bundle having (A) an average inter-fiber capillary width of from 25 to 400 microns, (B) a Specific Volume greater than 4.0 cc/gm, and (C) a MPFB greater than or equal to 0.14 cc/(den*hr), providing capillary forces on the liquid when the liquid is in contact with said distribution layer tending to transport the liquid parallel to said top layer, and (3) a resistance layer having a resistance layer top surface and a resistance layer bottom surface, said resistance layer provides resistance to transmission of the liquid from said resistance layer top surface to said resistance layer bottom surface.
