An absorbent article has an elastic waist portion, an absorbent element (), and a liquid-impermeable outer layer () which is intended to enclose the absorbent element on at least that side thereof which faces away from the wearer during use of the article. The absorbent element () is in its entirety arranged on the second piece (). The liquid-impermeable outer layer () is breathable, at least over a portion of this which covers the absorbent element ().

Absorbent article

An elasticized web has a gatherable substrate and a multi-strand elastic yarn affixed to the gatherable substrate at a plurality of fixation locations. So that the yarn can be affixed to the substrate without the use of an adhesive, the yarn is subjected to forces to create partial delamination of the yarn at the fixation locations and a portion of the gatherable substrate is caused to pass between the thus delaminated strands of the multi-strand elastic yarn. The elasticized web of the present invention is particularly suitable for use in disposable absorbent articles.

Elasticized web and a method and apparatus for its manufacture

A method of measuring the liquid retention of absorbent articles ( ) of the kind that includes an absorbent body having a top side which lies proximal to the wearer's skin when the article is worn, and a bottom side which is covered by a liquid-impermeable backing sheet, wherein the method comprises the steps of applying a determined amount of liquid to a region on the top side of the article, urging a pressure body ( ) against a region of the top side of the article with a given force, and collecting and measuring the amount of liquid pressed out from the top side of the article. The force with which the pressure body ( ) is pressed against the top side of the article, is set selectively on a device ( ) for pressing the pressure body against the top side of the article ( ), and the liquid pressed from the top side of the article is transported to a measuring vessel ( ) with the aid of sub-pressure.
