CA 2157757

The invention provides composite elastic nonwoven fabrics and the process of making them. The elastic nonwoven composite fabrics of the invention are formed from the combination of a plurality of cooperative elastic layers including an elastomeric meltblown web and an elastomeric spunbonded web. The elastomeric layers are joined together in a unitary elastic fabric structure to provide a composite having a desirable combination of elastic and barrier properties.

L'invention concerne des tissus non tissés, élastiques, composites et leur procédé de fabrication. Les tissus composites, non tissés, élastiques de l'invention sont obtenus à partir de la combinaison d'une pluralité de couches élastiques coopératives comprenant une couche gonflée par fusion, élastomère et une couche non tissée, élastomère. Les couches élastomères sont réunies en une structure unitaire de tissus élastiques afin de former un composite ayant une combinaison désirable de propriétés élastiques et propriétés barrière.
