Absorbent articles with improved absorption properties

摘要

An absorbent article such as disposable diaper, training pant, and adult incontinence undergarment comprising an absorbent structure comprising superabsorbent polymer particles, the article being able to absorb and contain body exudates and having improved absorption properties and therefore being able to reduce leakage, especially at the first gush, i.e. when the article starts to be wetted.

主权项

1. An absorbent article comprising an absorbent structure, 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 structure comprising an absorbent core, the absorbent core having a dry thickness at a crotch point of the article of from about 0.2 to about 5 mm, wherein one or more portion(s) of the absorbent structure comprise(s) at least about 90% by weight of superabsorbent polymer particles and require(s) a time to reach an uptake of about 20 g/g (T20) of less than about 440 s as measured according to the K(t) test method;
wherein the superabsorbent polymer particles are comprised in the absorbent core, such that the superabsorbent polymer particles are deposited between a first and a second substrate layer, with the first substrate layer facing towards the backsheet and the second substrate layer facing towards the topsheet wherein the one or more portion(s) of the absorbent structure have an effective permeability at about 20 minutes (K20) of at least about 2.9*10−8 cm2 as measured according to the K(t) test method.
