Abstract

Le monofilament antisalissures, d'une résistance d'au moins 36 cN/tex et d'un allongement inférieur à 44 %, presente, après cinq cycles d'encrassement et de nettoyage, un indice d'encrassement AI<2. Pour la fabrication de ce monofilament, un copolymérisat double point de fusion est compris entre 255 °C et 275 °C, préparé à partir d'alcènes et de perfluoroalcènes, est incorporé, avant extrusion, à une masse fondue polymère de polyéthylènetéréphtalate. Le monofilament est utilisé de préférence pour la fabrication de tamis en tissu, du type tamis pour machine à papier, d'une bonne stabilité au nettoyage, pour la section de séchage d'une machine à papier. Des tissus fabriqués avec un tel monofilament peuvent être généralement utilisés comme tissus techniques, lesquels doivent être nettoyés dans des conditions difficiles.
