Title (EN) MULTIFIBROUS MULTILAYER COMPOSITE MATERIAL FOR APPLICATIONS IN THE AUTOMOTIVE SECTOR
(FR) MATÉRIAU COMPOSITE MULTICOUCHE MULTIFIBREUX DESTINÉ À DES APPLICATIONS DANS LE SECTEUR AUTOMOBILE
Abstract:
(EN) The present invention concerns a process for preparing a microfibrous multilayer composite material comprising: 1 ) realizing a non-woven microfibrous semi-finished product made up of microfibres of one or more polymers dispersed in a polyurethane matrix (semi-finished product IE); 2) cutting the semi-finished product lengthwise into two layers; 3) buffing at least one layer on one side (side N) so as to extract the microfibres and form the nap, thereby obtaining a semi-finished raw product; 4) cutting at least one semi-finished raw product lengthwise parallel to the surfaces, producing an non-woven intermediate product, containing the buffed side (side N) and a waste layer (containing the side that has not been buffed - side S); 5) coupling the non-woven intermediate product (on the side opposite side N) to a fabric made of polyethylene terephthalate fibres by means of the application of a thermoplastic polyurethane adhesive that can be cross-linked between the non-woven intermediate product and the fabric; 6) submitting the multilayer composite material to a jet dyeing process. The invention also concerns a multilayer composite material that can be obtained by the process of the invention and the use thereof for covering the internal side of roofs or headliners of vehicles and for covering furnishing elements.
(FR) La présente invention concerne un procédé de préparation d'un matériau composite multicouche microfibreux comprenant les étapes consistant : 1) à réaliser un produit semi-fini microfibreux non tissé constitué de microfibres d'un ou de plusieurs polymères dispersés dans une matrice de polyuréthane (produit semi-fini IE) ; 2) à découper le produit semi-fini dans le sens de la longueur en deux couches ; 3) à polir au moins une couche sur un côté (côté N) de façon à extraire les microfibres et à former le duvet, obtenant ainsi un produit brut semi-fini ; 4) à découper au moins un produit brut semi-fini dans le sens de la longueur parallèlement aux surfaces, à produire un produit intermédiaire non tissé, contenant le côté poli (côté N) et une couche de déchets (contenant le côté qui n'a pas été poli - côté S) ; 5) à accoupler le produit intermédiaire non tissé (sur le côté opposé au côté N) à un tissu constitué de fibres de polyéthylène téréphtalate au moyen de l'application d'un adhésif polyuréthane thermoplastique qui peut être réticulé entre le produit intermédiaire non tissé et le tissu ; 6) à soumettre le matériau composite multicouche à un procédé de coloration par jet. L'invention concerne également un matériau composite multicouche qui peut être obtenu par le procédé de l'invention et son utilisation pour recouvrir le côté interne de toits ou de garnitures de toit de véhicules et pour recouvrir des éléments d'ameublement.
