摘要： An absorbent article, such as a diaper, sanitary napkin, adult incontinence device which has absorbent components comprised of blends of different types of fibers is provided. The absorbent components are arranged in structures that provide improved core integrity and liquid processing. The absorbent article preferably comprises a liquid pervious topsheet, a liquid impervious backsheet joined to the topsheet, an absorbent core positioned between the topsheet and the backsheet, and an acquisition layer overlying the absorbent core. The absorbent core comprises a blend of cellulosic fibers, absorbent gelling material, and fibers such as crimped synthetic fibers that form liquid stable bonds with adjacent layers. The acquisition layer also comprises at least some fibers that form liquid stable bonds with adjacent layers. The fibers that form liquid stable bonds in the absorbent core and the acquisition layer are bonded to liquid stable components. The liquid stable components can comprise the topsheet, the backsheet, and an optional intermediate liquid stable layer positioned between the acquisition layer and the absorbent core.

摘要： The present invention provides a method and apparatus for making absorbent structures having a layer of discrete particulate absorbent material which is divided into two or more bands (9) separated by a substantially particulate-free zone (11). The method of making such absorbent structures comprises the steps of first generating an initial particle suspension comprising a two-phase fluid of particles of absorbent gelling material suspended in a gas (such as air) flowing in an inlet duct. The initial particle suspension is then divided into multiple final particle suspensions in corresponding multiple branch ducts, each of the final particle suspensions having a given percentage of particles as a function of cross-sectional area of the inlet duct. The particles in the final particle suspensions are substantially uniformly distributed as a function of cross-sectional position in the branch ducts. Finally, the suspended particles are filtered from the final particle suspensions by capturing them on a substrate such as a layer of tissue. An apparatus in accordance with the present invention for practicing the above method comprises an inlet duct, a particle suspension generator in fluid communication with the inlet duct for generating the initial particle suspension, at least two branch ducts in fluid communication with the inlet duct, and a particle suspension divider disposed within the inlet duct for dividing the initial particle suspension into multiple final particle suspensions in the branch ducts. In a preferred embodiment, the apparatus further comprises an adhesive delivery device for adhesively coating the particles in the final particle suspensions to form adhesively coated particles.
