The present invention provides a method of adhering two or more components together by exposing a first component that includes cellulose ester fibers and/or a second component that includes a cellulose ester to a plasticizing solvent. The two components are then contacted together form a compound structure which is subsequently allowed to cure so that the two components are bonded together. The present invention is advantageously utilized to form a filter and in particular a cigarette filter and to form a multilayer automobile headliner. The present invention also provides a method of adhering a cellulose ester-containing automobile headliner to a vehicle passenger compartment ceiling. In this embodiment, a cellulose estercontaining composition is applied to the vehicle compartment ceiling prior to attachment of the headliner. The headliner and/or the vehicle passenger compartment ceiling are then exposed to a plasticizing solvent, contacted together, and then cured thereby adhering the headliner.
L'invention concerne un procédé permettant de faire adhérer mutuellement deux ou plus de deux composants par exposition d'un premier composant renfermant des fibres d'ester de cellulose et/ou d'un deuxième composant renfermant un ester de cellulose, à un solvant de plastification. On met en contact les deux composants pour former une structure de composé que l'on laisse ensuite durcir aux fins de liaison des composants entre eux. L'invention est avantageuse dans la réalisation d'un filtre et en particulier dans la réalisation d'une garniture de pavillon multicouche d'automobile. L'invention concerne aussi un procédé permettant d'assurer l'adhésion entre la garniture ainsi réalisée et un plafond d'habitacle de passager de véhicule. Selon cette variante, une composition à base d'ester de cellulose est appliquée audit plafond avant la fixation de la garniture. On expose ensuite la garniture et/ou le plafond en question à un solvant de plastification, avec durcissement ultérieur permettant l'adhésion de la garniture.
