摘要： The present invention provides absorbent articles, such as disposable diapers, which utilize substantially water-insoluble hydrogel material to enhance the absorbent capacity of such articles. In these articles, the hydrogel material, combined in particulate form with hydrophilic fiber material, is primarily placed in a lower fluid storage layer of the absorbent core of the article. Such a fluid storage lower layer of the absorbent core is placed underneath an upper, preferably larger, fluid acquisition/distribution layer containing little or no hydrogel. This lower fluid storage layer is positioned in such a manner that at least about 75% of the hydrogel in the lower layer is found in the front two-thirds of the absorbent article and such that at least about 55% of the hydrogel in the lower layer is found in the front half of the absorbent article. Absorbent articles of this type make especially effective and efficient use of the hydrogel material and may also provide a diaper rash control benefit. Absorbent cores of the type utilized in such articles are also disclosed.
摘要翻译：本发明提供了吸收制品，例如一次性尿布，其利用基本上不溶于水的水凝胶材料来增强这些制品的吸收能力。在这些制品中，将颗粒形式与亲水性纤维材料结合的水凝胶材料主要放置在制品的吸收芯的下部流体储存层中。吸收芯的这种液体储存下层被放置在含有很少或不含水凝胶的上部，优选较大的流体采集/分散层的下方。该下部液体储存层的定位方式是使得下层中的水凝胶的至少约75％存在于吸收制品的前三分之二中，并且使得至少约55％的水凝胶在下部在吸收制品的前半部分中发现层。这种类型的吸收制品特别有效和高效地使用水凝胶材料，并且还可以提供尿布疹控制益处。还公开了在这种制品中使用的类型的吸收芯。

摘要： Absorbent devices, such as catamenial tampons and catamenial pads. The devices comprise an unbonded array of non-absorbent, hydrophillic, resilient, moisture insensitive fibers contained within a porous overwrap. When the devices are intended to be presented in the compressed state, the compressed density of the mass of fibers should be less than about 0.3 grams per cubic centimeter. The devices can contain ancillary absorbent material.

摘要： The object of the invention is to provide an improved absorbent means that can be used in a catamenial device.The improved absorptive means comrpises a foam means having an absorbency improvement means at least arrayed on the surface of the foam means wherein the absorbency improvement means is adherent to the foam, hydrophilic, and has a high surface area. The foam means is preferably cut into small blocks made of hydrophilic polyester foam or hydrophilic polyurethane foam. Absorbency improvement means is preferably cellulose fibers.A tampon incorporating the improved absorbent means has overwrap 11 containing an aggregate absorbent body 12 comprising foam blocks coated with fibrous material 16 and ancillary absorbent material 17. The overwrap 11 is sealed by a side seam 13 and knotted at one end with a withdrawal string 15. The fiber coated foam blocks offer improved rate of absorbency, volume of absorbency, and retention of liquid under pressure due to more efficient utilization of the maximum absorbent capacity of the tampon. The fibrous coating of the foam blocks functions to wick liquid between a plurality of hydrophilic foam blocks and into the center of the foam blocks.

摘要： A disposable diaper combining improved softness and sufficient strength to resist in use tearing and shredding in a single structure, thereby producing better compliance and fit when the structure is applied to the wearer, and hence improved comfort as well as better containment of waste fluids deposited thereon. In a preferred embodiment, a disposable diaper of the present invention employs an air laid absorbent cellulosic core reinforced by the application of a hydrophobic resin at relatively low levels of solids addition to one side thereof with subsequent drying, curing and calendering to the desired overall density. With sufficient strength built into the resin treated surface of the absorbent core structure, the unreinforced surface of the absorbent core can be adhered directly to a soft, waterproof backsheet, thereby producing a unique softness, texture and hand. In addition to improved strength and softness, a resin-stabilized absorbent core of the present invention exhibits improved surface dryness due to favorable density and capillary gradients which provide improved liquid penetration from the resin treated surface of the core to the non-resin treated portions of the core. By combining the resin-stabilized absorbent core with a fast strike-through topsheet in a disposable diaper structure, the gasket-like waterproof side flaps normally required to prevent liquid run-off can be eliminated.
