ABSTRACT:
An absorbent article comprising a backing sheet of fluid impervious material, a fluid pervious cover sheet, and a first pad adjacent the cover sheet comprising a loosely formed fibrous mass. A separate second pad may be positioned intermediate the first pad and the backing sheet, with the second pad comprising a mass of fibers having compressed regions extending throughout a substantial part of the second pad. A polymer coating in the target area extends at least most of the width of the pads and extends between the third and the sixth tenth of the length of the pads. The polymer may be present on the top surface of the first pad (i.e. surface adjacent cover (top) sheet) and/or between the first and second pad and/or on the bottom or back surface of the second pad. Where only one pad is used, the polymer may be present on both the top and bottom surfaces thereof. When the polymer coating is on the top surface of the first pad and/or between the first and second pads, it is preferred that the coating be in the form of a plurality of spaced strips or bands horizontally or vertically disposed relative to the diaper length. The average interfiber spacings in the second pad are substantially less than the average interfiber spacings in the first pad such that the second pad rapidly transmits body fluids to remote locations of the second pad for retention in the areas at a location spaced from the cover sheet.
