Title (EN) MULTILAYER SHEET, AND METHOD FOR PRODUCING SAME
(FR) FEUILLE MULTICOUCHE ET SON PROCÉDÉ DE PRODUCTION
(JA) 多層シート及びその製造方法
Abstract:
(EN) Provided is a multilayer sheet which can be easily produced by laminating sheets having other functions, on a given sheet, by using a sheet having high yield and containing inorganic particles. A multilayer sheet according to one embodiment of the present invention has two or more layers of fiber-containing sheets laminated, wherein at least one layer sheet contains fibers, and composite fibers of inorganic particles, and is different in properties from the other layers of sheets.
(FR) L'invention concerne une feuille multicouche qui peut être facilement produite en stratifiant des feuilles possédant d'autres fonctions, sur une feuille donnée, en utilisant une feuille possédant un rendement élevé et contenant des particules inorganiques. Selon un mode de réalisation de la présente invention, la feuille multicouche possède au moins deux couches de feuilles stratifiées contenant des fibres, au moins une couche de feuilles contenant des fibres, et des fibres composites de particules inorganiques, et affichant des propriétés différentes de celles des autres couches de feuilles.
(JA) 歩留まり高く無機粒子を含有させたシートを用いて、或るシートに別の機能を有するシートを積層させて、容易に製造できる多層シートを提供する。 本発明の一態様に係る多層シートは、繊維を含むシートが2層以上積層しており、少なくとも1層のシートは、繊維と無機粒子との複合繊維を含み、別の層のシートとは異なる性質を有する。
