Zusammenfassung:In the present invention, mechanical properties of artificial leather are enhanced by impregnating and coating polyurethane manufactured by using a bio-polyol to the bio-polyol nonwoven fabric. The eco-friendly artificial leather using the bio-polyol according to the present invention includes: a bio-polyol nonwoven fabric impregnated with a polyurethane resin for impregnation; an adhesive layer on an upper surface of the bio-polyol nonwoven fabric coated with the polyurethane resin for bonding, which is manufactured using a bio-polyether polyol; and a coating layer coated on an upper surface of the adhesive layer with a coating polyurethane resin manufactured using the bio-polyether polyol. 본 발명은 바이오 폴리올 부직포에 바이오 폴리올을 활용하여 제조된 폴리우레탄을 함침 및 코팅시켜 인공피혁의 기계적 물성을 향상시킨 것으로, 본 발명에 따른 바이오 폴리올을 활용한 친환경 인공피혁은 함침용 폴리우레탄 수지가 함침된 바이오 폴리올 부직포, 상기 바이오 폴리올 부직포의 상면에 바이오 폴리에테르 폴리올(Bio-polyether polyol)을 이용하여 제조된 접착용 폴리우레탄 수지가 코팅된 접착층 및 상기 접착층 상면에 바이오 폴리에테르 폴리올(Bio-polyether polyol)을 이용하여 제조된 코팅용 폴리우레탄 수지가 코팅된 코팅층을 포함한다.
