Abstract: A multilayered elastic sheetlike structure and a process for producing it are described.The sheetlike structure consists of at least one elastomeric layer of a homogeneous film/sheet and at least one inelastic fibre or filament layer which is connected to the elastomeric layer at mutually spaced-apart connection sites. Between the connection sites the fibre or filament layer is in folds when the elastomeric layer is in an untensioned or partially tensioned state and smooth when the elastomeric layer is in the completely tensioned state. The inelastic fibre or filament layer consists of an originally smooth, undrawn or partially drawn material which has been melted or adhered to the untensioned elastomeric layer at the connection sites and, after conjoint extension therewith, exhibits a persistent extension.

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.
