| 摘要 |
The present invention relates to a producing method of suede-type artificial leather having antifouling properties, comprising the steps of: preparing an urethane pre-polymer; preparing fluorine-containing modified polyurethane by reacting the produced urethane pre-polymer with a fluorinated carbon compound having a hydroxy functional group in both ends of the fluorinated carbon compound; and immersing non-woven fabrics which forms artificial leather in an impregnation solution including the fluorine-containing modified polyurethane. According to the present invention, the suede type artificial leather having antifouling properties, in which a separate fluorine-based surfactant does not need to be used and artificial leather surface aging caused by using a fluorine-based surfactant does not occur, can be provided by using a fluorine-containing polyurethane elastomer provided with an antifouling function when producing the artificial leather. |
