Abstract

This invention relates to fibrous absorbent articles containing particles useful in the manufacture of disposable diapers, adult incontinence pads, sanitary napkins and the like. More particularly, the invention is directed to a multistrata fibrous web including a plurality of first strata including matrix fibers and thermoplastic fibers and a plurality of second strata including functional particles arranged in separated lanes. The first and second strata alternate through the web and the lanes of the second strata are arranged such that the lanes of adjacent second strata do not superimpose.
