Abstract

La présente invention concerne un appareil à fractionnement de liquides conçu pour la séparation d'un solvant ou d'un soluté à partir d'une solution alimentée sous pression au moyen d'au moins une membrane semi-perméable supportée par une étoffe portant elle-même en surface des cannelures multiples et formant un passage pour la solution filtrée sur la membrane semi-perméable. Dans cet appareil l'étoffe est constituée d'au moins un filé composite choisi dans le groupe formé par les filés mélangés comprenant au moins deux types de filaments séparés qui ont des caractéristiques différentes, l'un des filaments formant un premier composant du filé et l'autre filament un second composant du filé, et les filés à filaments composites constitués d'au moins deux types d'éléments de filaments ayant des caractéristiques différentes et adhérant entre eux en formant un seul filament, l'un des éléments du filament formant un premier composant du filé, l'autre élément du filament formant un second composant du filé, le premier composant 4 du filé étant fixé directement sur le filé et/ou sur les autres filés, rendant ainsi l'étoffe rigide, le second composant 3 de chaque filé formant une ossature pour l'étoffe.The present invention relates to a liquid fractionation apparatus adapted for the separation of a solvent or a solute from a solution supplied under pressure by means of at least one semi-permeable membrane supported by a fabric carrying it. even on the surface of multiple grooves and forming a passage for the solution filtered on the semi-permeable membrane. In this apparatus the fabric consists of at least one composite yarn selected from the group consisting of mixed yarns comprising at least two types of separate filaments which have different characteristics, one of the filaments forming a first component of the yarn and the other filament a second component of the yarn, and the composite filament yarns made up of at least two types of filament elements having different characteristics and adhering to each other forming a single filament, one of the elements of the filament forming a first component of the yarn, the other element of the filament forming a second component of the yarn, the first component 4 of the yarn being attached directly to the yarn and / or to the other yarns, thus making the fabric rigid, the second component 3 of each yarn forming a framework for the fabric.
