Abstract

L'invention concerne un tissu constitué de fils de chaîne et de fils de trame qui présente une structure, dans le sens des fils de chaîne, composée au moins de premiers, deuxièmes et troisièmes fils de chaîne (11, 13, 12) qui s'étendent les uns au-dessus des autres, l'invention étant caractérisée en ce que es troisièmes fils de chaîne (12) s'étendent toujours entre les premiers et deuxièmes fils de chaîne (11, 13), les fils de trame (16) étant passés à travers des foules alternées (35, 36, 37, 38) entre ces au moins trois fils de chaîne (11, 13, 12) de même qu'au-dessous et au-dessus de ceux-ci, et les troisièmes fils de chaîne (12) sont constitués d'une matière différente de celle des premiers et deuxièmes fils de chaîne (11, 13). L'invention concerne en outre un procédé de fabrication d'un tissu multicouche constitué de fils de chaîne et de fils de trame au moyen d'un métier à tisser.
