摘要： Methods and systems for making an absorbent pad for use in an absorbent article utilize a forming device for forming material into an absorbent core, a supply device for supplying a containment layer against the first surface of the absorbent core and spray apparatus for spraying fibers of molten resin onto the second surface of the absorbent core. The fibers form a stabilization layer on the absorbent core that increases the integrity of the absorbent core. The spray apparatus includes a nozzle having a resin aperture for exhausting resin therefrom and multiple gas apertures for exhausting gas therefrom to provide a random pattern to the fibers of molten resin as the fibers are sprayed onto the second surface. Resin can also be sprayed onto first and second portions of the containment layer extending outwardly from edges of the absorbent core so the containment layer and the stabilization layer encompass the absorbent core. In another embodiment, a second containment layer can be placed on the second surface of the absorbent core and first and second stabilization layers can be spaced outwardly therefrom and deposited on the absorbent core.

摘要： A conformable, absorbent structure having profiled stabilization and, consequently, decreased stiffness, includes an absorbent material at least partially stabilized with a binder material and located in a central longitudinal region and in two distal longitudinal regions located along opposite sides of the central longitudinal region. The absorbent material is more stabilized in the central longitudinal region than in either of the two distal longitudinal regions. The absorbent structure can be included in a number of absorbent articles, including diapers, training pants, swimwear, absorbent underpants, adult incontinence products, and feminine hygiene products, for example. The invention also includes a method of forming an absorbent structure having profiled stabilization.

摘要： A filter made from a nonwoven spunbond web comprising a plurality of continuous intertwined filaments, each filament having a diameter of about 25 to about 100 microns, predominantly present in the web as loop springs having diameters of about 1 to 3 millimeters. The web is made from a plurality of spunbond filaments laid randomly onto a moving belt. The webs of the present invention find particular utility when formed into cylinders as filters for smoking articles. In the smoking articles, the filters of the invention have a desirable degree of firmness while demonstrating an acceptable pressure drop.
