ELASTOMERIC LAMINATES HAVING RANDOM COPOLYMER FACINGS

An elastomeric laminate that includes at least one facing layer laminated to an elastomeric layer. The facing layer or layers may be nonwoven web(s) made up of thermoplastic filaments formed from a random copolymer or a random copolymer blend. The invention further includes an ultrasonically bonded...

Beschreibung
Zusammenfassung:	An elastomeric laminate that includes at least one facing layer laminated to an elastomeric layer. The facing layer or layers may be nonwoven web(s) made up of thermoplastic filaments formed from a random copolymer or a random copolymer blend. The invention further includes an ultrasonically bonded seam formed by ultrasonically bonding the elastomeric laminate to a substrate, and the method therefor. L'invention concerne un stratifié élastomère comprenant au moins une couche de revêtement stratifié sur une couche élastomère. La couche ou les couches de revêtement peut/peuvent être une/des bande(s) non tissée(s) constituée(s) de filaments thermoplastiques formés à partir d'un copolymère aléatoire ou d'un mélange de copolymères aléatoires. L'invention concerne également une couture liée par ultrasons formée par liaison à ultrasons du stratifié élastomère au substrat, et le procédé afférent.
