Abstract
In an absorbent article, such as a diaper or incontinence briefs, an elastic member comprising a net-like elastic substrate to which fibers 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. When the topsheet is physically deformed to impart stretchability, the fibers of the elastic member form a soft and resilient layer and prevent direct contact of the elastic member and the user's skin in case of thinning of the topsheet.
