Embodiment Construction

[0015] A. Definition

[0016] The term "absorbent core" as used herein refers to a component of an absorbent article which primarily determines the fluid handling properties of the article, including acquiring, transporting, distributing and storing body fluids. As such, the absorbent core typically does not comprise the topsheet or backsheet of the absorbent article.

[0017] The term "absorbent member" as used herein refers to a component of the absorbent core that typically provides one or more fluid handling properties, eg, fluid acquisition, fluid distribution, fluid transport, fluid storage, and the like. The absorbent member may supply the entire absorbent core or only part of the absorbent core, ie the absorbent core may comprise one or more absorbent members.

[0018] The term "comprising" used herein means, for example, that various components, components, steps, etc. may be used in combination according to the present invention. Thus, the term "comprising" include...

Abstract

The present invention relates to absorbent members for use in the absorbent core of absorbent articles for receiving and retaining bodily exudates such as urine. Such articles are disposable hygiene articles such as baby diapers, training pants, adult incontinence articles, feminine care articles, and the like. The improvements are essentially based on the recognition that it is desirable to replace most or all of the cushion fibrous absorbent material in an absorbent core with a fluid storage material capable of retaining fluid while maintaining or improving acquisition behavior, since the gain in comfort is greatly Compensated for pad reduction. The absorbent core of the absorbent member comprises a swellable hydrogel-forming polymer in combination with at least one hydrophilic polymer having a dendritic structure and at least one water-insoluble phosphate.

Description

field of invention [0001] The present invention relates to absorbent structures for use in absorbent cores of absorbent articles for receiving and retaining bodily exudates such as urine. The articles are disposable hygiene articles, such as baby diapers, training pants, adult incontinence articles, feminine care articles, and the like. The improvement is essentially based on the recognition that it is desirable to replace most or all of the cushion fibrous absorbent material in the absorbent core with a fluid storage material capable of retaining fluid while maintaining or improving the acquisition behavior, since the gains in comfort largely compensate Reduced cushioning. However, comfort cannot be achieved until the more fundamental requirements of the diaper for liquid management are met or improved. In particular, if such liquid handling properties are improved over the performance of conventional absorbent structures in order to be able to produce thinner and drier abs...
