Abstract

L'invention concerne une structure de tissu non tissé comprenant des amas de fibres constitués de fibres courtes collées les unes aux autres, caractérisée en ce que ces amas de fibres comprennent des fibres de matrice et des fibres de liaison. L'invention concerne également un procédé de production de cette structure de tissu non tissé, consistant à mélanger les fibres de matrice et les fibres de liaison, à former des bandes de fibres, à soumettre ces bandes à une première fusion thermique au moyen d'un traitement thermique afin de préparer le tissu non tissé, à convertir le tissu non tissé en amas de fibres de taille plus petite que celles du tissu non tissé, à fabriquer ces amas de fibres selon une forme désirée, puis à soumettre le produit fabriqué à une seconde fusion thermique au moyen d'un traitement thermique. La structure de tissu non tissé est légère, présente une distribution à densité uniforme, et est manifestement appropriée, par exemple, pour un coussin possédant une excellente récupération après application d'une charge pendant une longue durée.
