The present invention relates to disposable personal care products, such as diapers, feminine care products and adult incontinence products. More specifically, the invention relates to such products having improved absorbent core integrity and core absorbency. These products eliminate the need for costly adhesives The present invention also comprises a method for making the products of the invention. The method includes forming a plurality of localized compressions by ultrasonically compressing the natural fiber core between, although not necessarily adjacent to, at least one upper and at least one underlying fusible material. The periphery of the article is then bonded by conventional means, such as adhesives, crimping or fusing. This process reduces costs associated with the manufacturing of such articles by eliminating or reducing the amount of adhesives in the final product, and by eliminating costly and intermittent bonding procedures. The method also improves the continuum of the absorbent core without increasing material and manufacturing costs associated with these products.
