Problems solved by technology
[0010] Another problem posed by thin and flexible superabsorbent articles is that they do not maintain the desired shape in order to maximize the rate of fluid absorption and maintain a comfortable next-to-body shape as the user goes about their daily activities, especially when This is especially true when the absorbent article is loaded after repeated insults with urine or menses

[0054] As stated above, the present invention relates to absorbent articles having a number of readily measurable properties within certain defined optimum ranges. Each range of each property provides an absorbent article according to the present invention, but the different ranges and preferred ranges may be combined in any way to develop embodiments of the present invention.
[0055] The properties in question are the following:
[0056] a) % Thickness Swell as measured at five minutes according to the Dynamic Thickness Swell Test;
[0057] b) % Thickness Swell as measured at one minute according to the Dynamic Thickness Swell Test;
[0058] c) Dry Peak Hardness as measured by the Gather Compression Test;
[0059] d) Acquisition rate and rewet as measured according to the SABAP test;
[0060] e) dry thickness;
[0061] f) % Thickness Swell measured at 5 min or 1 min according to Dynamic Thickness Swell Test.
[0062] Dynamic thickness expansion tests were performed as d...

Abstract
The present invention relates to an absorbent article, comprising a fluid permeable topsheet, a backsheet, an absorbent element disposed between the topsheet and the backsheet wherein the absorbent article has a caliper expansion measured at 5 minutes of at least 275%. The present invention also relates to an absorbent article, comprising a fluid permeable topsheet, a backsheet, an absorbent element disposed between the topsheet and the backsheet wherein the absorbent article has a dry caliper of 4.5 mm or less and wherein the absorbent article has a caliper expansion, measured at five minutesof at least 75%. The present invention also relates to an absorbent article, comprising a fluid permeable topsheet, a backsheet, an absorbent element disposed between the topsheet and the backsheet wherein a ratio of the caliper expansion measured at 5 minutes to the dry peak stiffness is at least 0.5% / N.
Description
technical field [0001] The present invention relates to absorbent articles which are particularly thin and flexible and are able to retain their shape and move with the body like clothing, but still have a high capacity to absorb fluids and are particularly effective in absorbing these fluids in a rapid manner . [0002] This is particularly relevant to products that are worn every day and that may have to absorb large amounts of urine discharge, and includes products that are worn for both menstrual and incontinence use. [0003] Absorbent articles according to the invention may be, for example, diapers, incontinence briefs, training pants, diaper fasteners and liners, hygiene garments, and the like. Background technique [0004] In providing a thin, flexible, garment-like, yet highly absorbent product, there are two specific challenges; the first is having sufficient fluid storage volume within the core system to accommodate large volumes of excreta, and the second The s...
