Abstract
An absorbent article such as disposable diaper, training pant, and adult incontinence undergarment comprising superabsorbent polymer particles able to absorb and contain body exudates having improved absorption properties and, therefore, reduce leakage, especially at the first gush, i.e. when the article starts to be wetted.
Claims19
An absorbent article comprising an apertured top sheet and an absorbent core, the absorbent article being divided into three portions:
- a front portion, a back portion and a crotch portion disposed between the front portion and the back portion, the absorbent core having a dry thickness at a crotch point of the article of from 0.1 to 10 mm;
- wherein the absorbent core comprises superabsorbent polymer particles;
- wherein the superabsorbent polymer particles comprised by the absorbent core in the front portion or the crotch portion of the absorbent article or by the whole absorbent core have an effective permeability at 20 minutes (K20) of at least 5·10−8 cm2 as measured according to the K(t) Test Method;
- and
- wherein the superabsorbent polymer particles have a UPM value of from 40 to 150 (10−7 (cm3·s)/g).
An absorbent article comprising an elastic waist feature and an absorbent core, the absorbent article being divided into three portions:
- a front portion, a back portion and a crotch portion disposed between the front portion and the back portion, the absorbent core having a dry thickness at a crotch point of the article of from 0.1 to 10 mm;
- wherein the absorbent core comprises superabsorbent polymer particles;
- wherein the superabsorbent polymer particles comprised by the absorbent core in the front portion or the crotch portion of the absorbent article or by the whole absorbent core have an effective permeability at 20 minutes (K20) of at least 5·10−8 cm2 as measured according to the K(t) Test Method;
- and
- wherein the superabsorbent polymer particles have a UPM value of from 40 to 150 (10−7 (cm·s)/g).
An absorbent article comprising an absorbent core, the absorbent article being divided into three portions:
