Abstract

La présente invention concerne un filament composite à deux composants à haute résistance à structure peau-âme et un procédé de fabrication s'y rapportant. Le filament composite est composé d'une couche de peau et d'une couche d'âme. Le matériau de la couche de peau représente 10 à 30 % en poids du filament composite et le matériau de la couche d'âme représente 70 à 90 % en poids du filament composite. Le matériau de la couche de peau est composé de polyéthylène HDPE, d'un mélange maître de teinture et d'un mélange maître d'antioxydant et le matériau de couche d'âme est composé de polypropylène présentant un module d'élasticité en flexion élevé, d'un mélange maître de teinture et d'un mélange maître d'antioxydant. Le PP de la couche d'âme est du polypropylène présentant un module d'élasticité en flexion élevé. Le PE de la couche de peau est du polyéthylène haute densité à bas point de fusion. Des fibres sont mises sous forme d'une structure peau-âme. Au moyen d'un fort allongement, la résistance des fibres est améliorée. Le filament est traité au moyen d'un lissage à flux d'air, d'air chaud et d'un aiguilletage de manière à faire fondre la couche de peau à bas point de fusion et les filaments fondus sont liés pour former un tissu. Le non-tissé des filaments présente les avantages suivants : du fait que les températures pour l'air chaud et l'aiguilletage sont faibles, le degré de cristallinité des fibres à haute résistance de la couche d'âme est protégé, le tissu est résistant et respirant, la perméabilité aux liquides est bonne et le filament peut être utilisé pour préparer un géotextile et une toile de filtration, qui peuvent être utilisés dans un environnement acide/alcalin.
