La présente invention concerne un cuir artificiel de type suédine présentant une propriété d'antisalissure, et concerne un cuir artificiel de type suédine présentant une propriété d'antisalissure, dans lequel un polymère élastomère est infiltré dans un tissu non tissé formé par entrelacement à trois dimensions d'une fibre ultrafine et un lainage est effectué, dans lequel l'élastomère polymère est un polyuréthane modifié contenant du fluor, et le polyuréthane modifié contenant du fluor est préparé de façon à avoir une masse moléculaire moyenne en poids (Mw) de 500000 à 800000 par préparation d'un prépolymère d'uréthane ayant une masse moléculaire moyenne en poids (Mw) de 400000 à 700000 par réaction d'un diol avec un diisocyanate, et à faire réagir le prépolymère préparé avec un composé de carbone fluoré dans lequel des groupes fonctionnels de type hydroxyle sont mis en œuvre au niveau des deux extrémités de celui-ci. Selon la présente invention, le cuir artificiel de type suédine présentant une propriété d'antisalissure, dans lequel un agent tensio-actif à base de fluor séparé pour une propriété d'antisalissure n'a pas besoin d'être utilisé et dans lequel le vieillissement de la surface du cuir artificiel causé par l'utilisation d'un agent tensio-actif à base de fluor ne se produit pas, peut être mis en œuvre par l'utilisation d'un élastomère de polyuréthane contenant du fluor doté d'une fonction antisalissure lors de la préparation du cuir artificiel.
