SUEDE TYPE ARTIFICIAL LEATHER WITH ANTIFOULING PROPERTY, AND PREPARATION METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2016/052906

Kind Code:

A1

Abstract:

The present invention relates to suede type artificial leather with an antifouling property, and relates to suede type artificial leather with an antifouling property, in which a polymer elastomer is infiltrated into a nonwoven fabric formed by three-dimensional interlacing of an ultrafine fiber and raising is carried out, wherein the polymer elastomer is a fluorine-containing modified polyurethane, and the fluorine-containing modified polyurethane is prepared so as to have a weight average molecular weight (Mw) of 500,000-800,000 by preparing a urethane prepolymer having a weight average molecular weight (Mw) of 400,000-700,000 by reacting a diol with a diisocyanate, and reacting the prepared prepolymer with a fluorinated carbon compound in which hydroxyl functional groups are provided at both ends thereof. According to the present invention, the suede type artificial leather with an antifouling property, in which a separate fluorine-based surfactant for an antifouling property 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 preparing the artificial leather.
