Embodiment 1

[0219] This example is intended to compare the fluid handling characteristics of a diaper according to the present invention to a diaper manufactured in accordance with US Patent Application Serial No. 10 / 776,851. Apart from the material used for the acquisition / storage layer, both diapers have identical construction. The respective materials and resulting core thicknesses are shown in Table 1, as well as the fluid handling properties of the cores.

Abstract

Absorbent articles are described having a thin conformable absorbent core, wherein the core has at least two layers, both of which are substantially free of cellulosic fibers. The first layer is intended to provide storage for most of the collected fluid and has an AAP of at least about 20 g / g; while the second layer provides temporary capacity for most of the collected fluid and permanent storage for at least a portion thereof, The second layer comprises a second absorbent polymer material having at least about 400 x 10 -7 (cm 3 seconds) / g moisture permeability. The second absorbent polymer material has a moisture permeability to SFC ratio of at least about 1.5:1 relative to the first absorbent polymer material.

Description

technical field [0001] The present invention relates to an absorbent article, preferably a disposable absorbent article such as a diaper. In particular, the present invention relates to absorbent cores for such absorbent articles which provide the articles with improved softness and conformity to the wearer's body. Such absorbent cores are also beneficial in providing absorbent articles with increased wearing comfort. Background technique [0002] Absorbent articles such as diapers and adult incontinence products are well known articles of commerce. Attempts have been made to make them have a generally good fit and high absorbent capacity. Modern diapers use absorbent polymer materials, also known as superabsorbent polymers, which can store large volumes of aqueous liquid (eg, about 300 mL for a typical baby diaper). [0003] Although such absorbent articles are typically disposable, they are often worn for many hours, both dry and filled with urine. Therefore, it is imp...
