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

specific Embodiment approach

[0050] 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 invention, but the different ranges and preferred ranges may be combined in any way to develop embodiments of the invention.

[0051] The properties in question are the following:

[0052] a) the thickness swell measured at five minutes according to the dynamic thickness swell test;

[0053] b) the thickness swell measured at one minute according to the dynamic thickness swell test;

[0054] c) Dry Peak Hardness as measured by the Gather Compression Test;

[0055] d) Acquisition rate and rewet as measured according to the SABAP test;

[0056] e) dry thickness;

[0057] f) Thickness expansion rate measured at 5 min or 1 min according to Dynamic Caliper expansion rate test.

[0058] Dynamic thickness expansion tests were performed as descr...

Abstract

The present invention relates to an absorbent article, comprising a fluid permeable topsheet, a backsheet and an absorbent element disposed between the topsheet and the backsheet wherein the absorbentarticle has a caliper expansion, measured at 1 minute of at least 150%. The present invention also relates to an absorbent article, comprising a fluid permeable topsheet, a backsheet and an absorbentelement disposed between the topsheet and the backsheet wherein the absorbent article has a ratio of dry caliper to the caliper expansion measured at 1 minute of 3 mm / % or less.

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 relates in particular to products which are worn every day and which may have to absorb large amounts of urine discharge, and includes products which are worn for 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 and 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 seco...
