The present invention is concerned with providing porous fluid handling materials whichnare resin bonded materials for being used as aquisition materials. The resin isnimpregnated into the web in a non-uniform distribution throughout the thikness of the webn(i.e. the smaller Z direction perpendicular to the cross machine direction -or width- andnthe machine direction of the web - or length-), such a resin has a higher concentrationnon a weight basis on a first surface than on a the second surface. The overall, average,nresin concentration is of about 25% of the basis weight, and the difference isnapproximated by having about two thirds of the total resin in the upper half of the web,nwhich comrises also the first surface and is intended to be directed towards the wearernwhen in use. |
