Abstract

L'invention concerne des procédés de formation de substrats multicouches comprenant des couches de surface supérieures et inférieures et une couche de matériau thermoplastique ramolli par fusion entre les couches de surface extérieures, le matériau thermoplastique comprenant du polyéthylène ou ayant une valeur de tan delta comprise entre 0,2 et 0,4 dans la plage de température allant de 100 °F à 350 °F. Les 3 couches (ou plus) sont assemblées et chauffées, et ramollissent par fusion le matériau thermoplastique, provoquant ainsi la liaison de la couche thermoplastique aux couches de surface extérieures. Une composition de nettoyage peut enfin être chargée sur le substrat multicouche, un trajet de fluide s'étendant à travers le matériau thermoplastique fondu permettant à la composition de nettoyage de se déplacer entre les couches de surface. L'adhérence entre les couches de surface et la couche thermoplastique est assurée par le matériau thermoplastique lui-même, qui se lie à des groupes de fibres dans les couches de surface. Le procédé ne nécessite pas d'adhésifs chimiques, pas d'eau de traitement, de séchage, ou analogue, de sorte qu'il peut être mis en œuvre avec un faible investissement de capitaux.
