In an absorbent article, such as a diaper or incontinence briefs, an elastic member (60) comprising a net-like elastic substrate (62) to which fibers (64, 66) are pre-bonded provides for a breathable elastic for use as a side- a waist- or leg elastic. The fibers that are bonded to the net-like substrate, for instance by hydro-entangling, ensure a soft and comfortable contact with the wearer's skin. In the side panels of the absorbent article, the elastic members have a large freedom of stretch without buckling taking place, thus reducing chances of leakage. When the elastic member is located between the topsheet and the backsheet, a strong connection of topsheet to backsheet is established using a relatively small amount of adhesive.

L'invention se rapporte à un élément élastique (60) utilisé dans un article absorbant tel qu'une couche ou un slip pour incontinents, qui se compose d'un substrat élastique en filet (62) auquel des fibres (64, 66) sont précollées, et constitue une matière élastique poreuse destinée à être placée sur les côtés, au niveau de la ceinture ou des cuisses. Les fibres qui peuvent être collées au substrat en filet par hydro-enchevêtrement sont d'un contact doux et agréable sur la peau de l'utilisateur. Lorsqu'ils sont placés dans les panneaux latéraux de l'article absorbant, les éléments élastiques présentent une grande capacité d'étirement sans gondolage, ce qui réduit les risques de fuite. Lorsque ledit élément élastique est placé entre la feuille avant et la feuille arrière, une liaison résistante est assurée entre ces deux feuilles au moyen d'une quantité relativement faible d'adhésif.
