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 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: A thin absorbent undergarment liner is provided which exhibits a clear, aesthetically pleasing embossed pattern on the body facing surface thereof while still maintaining the longitudinal edges soft and comfortable. The liner is provided to have areas of deep depressions on the body facing surface and shallow impressions on the longitudinal edges.

Abstract: An absorbent cellular polymeric material is provided which exhibits enhanced water retentivity and may also exhibit enhanced compressibility. Such a material is provided by foaming the reaction product of a poly(aminoether) and an epoxy resin and quaternizing the resulting reaction product with, for example, an acid. The foam is particularly usable in products for absorbing body fluids.

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: Absorbent retentive pulp, produced by mechanically treating a dispersion of cellulose fiber to the disintegrated and outer secondary walls to microfibrillar form. The beaten dispersion is then freeze dried.

Abstract: A hot melt pressure-sensitive adhesive is provided which is selected to exhibit critical rheological properties which manifest themselves into the desired performance criteria of tenacious bonding and clean release.

Abstract: An improvement in a process for producing an absorbent composite wherein a solution of acrylic or methacrylic acid salts are applied to a substrate and irradiated to form a water swellable polymer in-situ within such substrate. The component comprises saturating the irradiated substrate with an aqueous liquid and then drying to a moisture content of less than 20 percent by weight whereby the dried substrate exhibits rapid absorption properties.

Abstract: Hydrophilic, water retentive synthetic wood pulp fibers are provided which are capable of forming low density fluff. The fibers comprise polyolefins and polyvinyl alcohol wherein the polyvinyl alcohol has, grafted thereto, hydrophilic polymer moieties.

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 disposable diaper having a facing sheet defining a diaper inside surface for direction toward the wearer and a backing sheet defining a diaper outside surface is provided with adhesive tape tabs comprising first and second anchoring portions and an attachment portion. The anchoring portions are attached to the inside surface and the outside surface of the diaper at a marginal portion thereof. One of the anchoring portions is made from elastic web material, and the other anchoring portion is made from inelastic web material. The attachment portion is temporarily attached to the inelastic anchoring portion and adhesively secured to the elastic anchoring portion. In use, the temporary attachment is detached leaving only the adhesive securement of the attachment portion to the elastic anchoring portion to provide an elastic tape tab fastener.

Abstract: The absorbent material is treated to increase its wettability in a substantive manner. This is accomplished by reacting a diepoxide compound with an absorbent material selected to have accessible hydroxyl groups and with a surfactant having functional end groups selected from the group consisting of primary amine or hydroxyl groups.

Abstract: Methods, compositions and products are described which inhibit formation of undesirable products on body surfaces and environs resulting from microbial action on lipoidal materials in body secretions. Amino acid compounds are employed.

Abstract: An absorbent material is provided for body fluid absorbent products which material has relatively high tensile strength, and is extremely flexible and may be incorporated into absorbent products without substantial loss in user's comfort. The material is made by forming a slurry of water wherein the solids comprise cellulosic fibers and hydrocolloidal material. The wet web is formed from the slurry and the web is then dried. The dry web is then compacted to a density of at least 110% and preferably at least 150% based on the density of the dry web. The resulting product has a tensile strength of at least 10 Kg/cm.sup.2 and the Gurley Stiffness of less than about 40 gm.

Abstract: A fibrous sliver having particulate matter substantially homogeneously distributed therethrough is provided. The sliver is formed by first forming a low weight web of fibrous material and depositing unto said low weight web particulate material. The web is then compacted to the desired weight per unit area.

Abstract: Methods, compositions and products are described which inhibit the development of undesirable conditions arising as a result of microbial formation of ammonia from urea in excreted urine. Amino acid compounds are employed.
