The present invention is directed to an elastic laminate which is elastically extensible in at least one direction. The elastic laminate (70) includes an elastomeric material (124) having a first surface (150) and a second surface (152) opposing the first surface. The elastomeric material includes a polystyrene thermoplastic elastomer. The elastic laminate further includes a first nonwoven layer (122) including component fibers which include a polyester. The elastomeric material (124) is bonded to the first nonwoven layer (122) through a continuous heat/pressure bond which is formed by application of a bonding temperature which is lower than the melting point of the polyester. The present invention is also directed to a disposable garment employing such an elastic laminate.
L'invention concerne un laminé élastique (70), à capacité d'élongation élastique au moins selon une direction, qui comprend : un matériau élastomère (124) ayant une première surface (150) et une seconde surface (152) opposée à la première surface. Le matériau élastomère comprend un élastomère thermoplastique à base de polystyrène, et une première couche non tissée (122) dont les fibres renferment un polyester. Le matériau élastomère (124) est fixé à la première couche (122) via une liaison continue réalisée à chaud/sous pression, par application d'une température de soudage inférieure au point de fusion du polyester. L'invention concerne également un vêtement jetable à base de ce laminé.
