| 摘要 |
The present invention relates to a solvent-free polyurethane-based artificial leather having the texture of human skin, and particularly to artificial leather comprising soy protein isolate and solvent-free polyurethane resin, where the use of soy protein isolate provides a higher water content than that of the conventional artificial leather to improve sensitivity properties such as tactile sensation and the use of the solvent-free polyurethane resin provides higher heat resistance and better mechanical properties than those of the conventional artificial leather, without using an organic solvent, thereby enabling to maintain clean indoor air.
