Abstract: Restrained bales are formed for transporting high-bulk, crosslinked cellulose fiber in a reduced volume. A limited amount of force is used in compressing the fiber into the bales so that the fiber is not damaged. The limited amount of force used allows the bale, when restraints are released, to expand to about twice its restrained volume. Fiber damage is further minimized by limiting the amount of compression to the minimum required so that a transport container is completely filled to its volume and payload capacities.

Abstract: An apparatus is disclosed for preparing a quantity of individual treated fibers from one or more fiber mats. The apparatus comprises a fiber treatment zone, a conveyor for conveying each mat through the fiber treatment zone, wherein each mat is impregnated by an applicator with a treatment material, such as a crosslinking substance, and directly to an attrition device. The attrition device fiberizes the mats to form a fiber output having a low nit level, such as no more than about three, and a dryer for both drying the fiber output and curing the crosslinking substance. The fiberizer is configured to minimize the accumulation of fiber at locations therein. An optional component of the fiberizer is a novel fluff generator comprised of multiple rotors each having plural longitudinally extended rows of radially extending rotor pins that rotate past groups of shorter pins mounted on the inside surface of the fluff generator housing.

Abstract: A fiberizer is described having a rotor to which plural hammers are mounted for fiberizing a sheet of fibers delivered to the rotor as the rotor is rotated. A feed mechanism utilizing a pair of seal rollers, at least one of which is driven, is configured for effective delivery of both wet or dry sheets to the fiberizer. The hammers are configured to minimize dead spaces within the fiberizer. In addition, air flow is directed through the fiberizer to minimize accumulations of fibers therein. Furthermore, an optional liquid flushing mechanism is provided for periodically cleaning the fiberizer during use.

Abstract: Le dépastilleur possède un rotor sur lequel sont montés plusieurs marteaux pour dépastiller une feuille de fibres amenées au rotor pendant que ce dernier tourne. Un mécanisme d'alimentation utilisant une paire de cylindres d'étanchéité, dont au moins l'un est entraîné, est configuré pour amener des feuilles mouillées ou séches au dépastilleur. Les marteaux sont conçus pour réduire au minimum les espaces morts à l'intérieur du dépastilleur. De plus, l'écoulement d'air est dirigé au travers du dépastilleur d'une manière telle que les accumulations de fibres à l'intérieur du dépastilleur sont réduites au minimum. En outre, l'option d'un mécanisme de décharge de liquide est prévu pour assurer le nettoyage périodique du dépastilleur pendant son utilisation.

Abstract: An absorbent composite having a reticulated core and a fibrous stratum is disclosed. The core and stratum are integrally formed, and the stratum is coextensive with an outward surface of the core. In one embodiment, the composite includes strata on opposing outward facing surfaces of the core. The core includes a fibrous matrix and absorbent material. The fibrous matrix defines voids and passages between the voids, which are distributed throughout the composite. Absorbent material is located within some of the voids. On wetting, absorbent material located in these voids is expandable into the void. Absorbent articles that include the composite are also disclosed.

Abstract: On forme des balles serrées afin de transporter dans un volume réduit des fibres de cellulose réticulées ayant un grand volume. On applique une force limitée lorsque l'on comprime les fibres dans les balles afin de ne pas endommager les fibres. Cette quantité limitée de force permet à la balle de se dilater jusqu'à deux fois environ son volume serré, une fois que l'enserrement est défait. On minimise davantage l'endommagement des fibres en limitant la compression au minimum requis, de sorte qu'un conteneur de transport soit complètement rempli, jusqu'au maximum de sa capacité en volume et en charge utile.

Abstract: Methods for forming an absorbent fibrous composite containing absorbent material dispersed in bands through the composite and along the composite's length are disclosed. The methods generally include depositing a fibrous slurry on a foraminous support (202, 204) to form a web and depositing or injecting absorbent material into the web across its width to provide a web (126) having absorbent material in bands along the composite's length. Drying the web provides a fluted absorbent composite. In one embodiment, the method is a wet-laid method and in another embodiment, the method is a foam-forming method. Preferably, the methods are twin-wire forming methods.

Abstract: An absorbent composite (10) that includes a fibrous matrix having absorbent material dispersed in bands (12) along the composite's length is disclosed. The bands define liquid distribution zones (14). On liquid contact, absorbent material material swelling occurs and produces a wetted composite having flutes that include swollen absorbent material separated by distribution zones (14), regions of the composite that are substantially free of absorbent material. Absorbent articles that include the composite are also disclosed.
