Abstract: An adhesive resealable tab fastener means suitable for use on a disposable diaper is provided which minimizes tearing of the tab fastener means itself or tearing it from the diaper when opening and closing repeatedly. The tab fastener means is provided with a grippable holding means and a grippable carrying tape segment. By being able to grip both parts of the tab fastener means, accidental tearing or rupturing of the fastener or diaper is minimized.

Abstract: Nonwoven, air-laid fabrics formed predominantly of textile length, synthetic, resilient fibers of staple length, the fabric being resin-bonded and having a density less than about 0.06 gm/cc at 0.16 lb/sq. in. load and a weight less than 3 oz/sq. yd. The fabric is resin-bonded using a bonding solution providing less than 180% solution pickup and more than 15% dry solids add-on. The fabric is used as a facing or covering for disposable diapers, sanitary napkins, incontinent pads, tampons and the like.

Abstract: A batt of non-delignified fibers is stabilized by applying ultrasonic energy thereto in narrow compressed lines which aid in distributing liquid within the batt. The fibers are partially delignified at fiber intersections which are hydrogen bonded. Supplementary stabilization may be provided by thermoplastic bond sites.

Abstract: A superthin absorbent disposable product is provided having an absorbing layer containing superabsorbent and a wicking layer. The product is suitable for use in disposable diapers, sanitary napkins, incontinent pads, wipes and the like.

Abstract: A disposable diaper is provided which has a pressure-sensitive adhesive closure, a moisture-permeable facing sheet, and a polyethylene moisture-impermeable backing sheet. The pressure-sensitive adhesive closure has an adhesive composition that permits reopening the diaper numerous times without substantial damage to the polyethylene backing sheet or to the adhesive closure.

Abstract: A superthin absorbent disposable product is provided having an absorbing layer containing superabsorbent and a wicking layer. The product is suitable for use in disposable diapers, sanitary napkins, incontinent pads, wipes and the like.

Abstract: An absorbent batt of non-delignified fibers is stabilized by applying a lignin solvent to an assemblage of such fibers to soften at least 10 percent of the fibers. When the fiber assemblage is compressed and the solvent is removed, the softened lignin of adjacent contacting fibers cause a lignin-to-lignin interfiber bond to occur at the fiber intersection.

Abstract: This invention relates to an improved method for rendering discrete portions of a moving web with an elasticized character while preserving the inelastic character of the remaining portions of the substantially inelastic web. The method is especially suitable for use in the manufacture of disposable diaper components and the like.

Abstract: The present invention provides an absorbent structure comprising a moisture-impermeable backing, an absorbent batt and a moisture-permeable cover covering at least the side opposite the moisture-impermeable backing. The absorbent batt is of loosely-compacted, cellulosic fibers and is provided with a reservoir having a capacity of at least 10 cc. The reservoir is formed by compression of the fibers in the reservoir zone and is located so that the product, when worn, retains the proper shape.

Abstract: A superthin absorbent disposable product is provided having an absorbing layer containing superabsorbent and a wicking layer. The product is suitable for use in disposable diapers, sanitary napkins, incontinent pads, wipes and the like.

Abstract: This invention comprises pleating a fabric, securing an elastic member in a relaxed state to the pleated fabric and then removing the pleats from the fabric. On removing the pleats, the elastic member is stretched to provide elastic areas in the previously pleated portions and non-elastic areas in the previously unpleated portions of the fabric.

Abstract: An absorbent structure of loosely compacted cellulosic fibers substantially rectangular in shape having increasing gradient densities from the central portion to each transverse end and methods for making the structure.

Abstract: A disposable diaper having improved fit about the legs and/or waist of the wearer and having reinforced corners for enhanced securement of the diaper about the wearer is disclosed. Improved fit and reinforcement are obtained by an elongated, inherently elastic ribbon member positioned along at least one margin of the diaper. The ribbon member is secured to the diaper so as to provide an elastic region at a central portion of the margin and a unitary, relatively inelastic reinforced region in a corner portion of the diaper.

Abstract: A disposable diaper having improved fit and liquid containment provided by gathering means adjacent at least one edge of the absorbent panel, said gathering means including at least two separately extending, effectively elastic elements. Each of the effectively elastic elements applies a gathering force to a zone of the diaper, thereby defining multiple lines of gasketing about the leg or waist openings.

Abstract: A high loft, low density, nonwoven fibrous web is provided comprising a plurality of irregularly arranged, intersecting, overlapping, mechanically interengaged, loosely assembled fibers including both thermoplastic synthetic wood pulp fibers and other fibers, segments of the thermoplastic synthetic wood pulp fibers being heat fused at a plurality of junctures with segments of other thermoplastic synthetic wood pulp fibers and with segments of fibers of other types, with additional binder distributed throughout the web.The web is prepared by air-laying a blend of thermoplastic synthetic wood pulp fibers and other fibers applying heat without pressure to the air-laid blend to fuse at least some of the thermoplastic synthetic wood pulp fibers to each other and to some of the other fibers to form a self-supporting fibrous web, introducing a latex binder into the web and drying and curing the binder.

Abstract: The invention relates to a method and apparatus for partitioning and/or shaping a batt by gripping the batt with resilient means or, alternatively, with resilient means and non-resilient means, and by stressing or severing the batt without the formation of compaction areas on the parted edges of the batt.

Abstract: The invention provides an absorbent panel which consists of a paper, film or fabric substrate coated on at least one surface with a reactive composition containing from 10 to 40 parts by weight of a liquid polyhydroxy organic compound and from 90 to 60 parts by weight of a particulate water-insoluble, water-swellable absorbent polymer having a gel capacity of at least 10. The absorbent panel is capable of absorbing at least 15 times its weight of liquid and is a thin structure.

Abstract: A laminated structure, such as a disposable diaper is provided which includes elastic in the margin to provide gasketing about the legs and, if desired, an improved fit about the waist. A method is provided for placing elastic only in the areas to be gathered and removing the unused elastic. In the method stretched elastic is intermittently adhered to a web substrate along a longitudinal line at the terminating portion of the gasketed area. The elastic is then severed adjacent the adhered portions and the unused elastic is removed.

Abstract: Method and apparatus for continuously attaching an elastic member to discrete portions of a moving web to impart an elasticized character to predetermined portions of the web while preserving the inelastic character of the other portions of the web.

Abstract: A disposable diaper having constringent means in the longitudinal side margins is disclosed. The constringent means foreshortens the side margins and acts on an absorbent batt contained within the diaper to bulge the side margins of the batt.
