An automotive tufted carpet with improved acoustic properties is formed with a two-part primary backing. The first backing layer is formed of a woven or non- woven or spunbond material, and the second backing or layer is formed of a microfilament spunlaced material possessing sound absorbing acoustic properties. The tufts of yarn are sewn through both parts of the primary backing which are then thermobonded together with an adhesive web positioned therebetween. The resulting acoustically enhanced automotive tufted carpet may be backcoated or precoated, and may have a secondary backing adhered thereto as a matter of choice.

L'invention concerne un tapis tufté (10) pour voiture possédant des propriétés acoustiques améliorées et étant constitué d'un dossier principal en deux parties. La première couche (14A) du dossier est conçue dans un matériau tissé ou non tissé ou filé-lié et la seconde couche (14B) du dossier est conçue dans un matériau non tissé lacé par filage à microfilaments possédant des propriétés acoustiques isophoniques. Les touffes de fils (12) sont cousues dans les deux parties du dossier principal (14), puis elles sont thermoliées ensemble au moyen d'une toile adhésive (16) positionnée entre celles-ci. Le tapis tufté (10) pour voiture à propriétés acoustiques améliorées peut être revêtu sur l'envers ou revêtu au préalable (18) et peut présenter un dossier secondaire (20) adhéré sur celui-ci en fonction des goûts.
