평균 섬도 0.07 ∼ 0.9 dtex 의 폴리에스테르 섬유를 포함하는 부직포와 부직포에 부여된 고분자 탄성체를 포함하고, 폴리에스테르 섬유는 농색 안료를 0.5 ∼ 10 질량％ 함유하고, 적어도 일면의 폴리에스테르 섬유가 입모된 입모면을 갖고, 또한 입모면은 Lab표색계에 기초하는 명도 L값≤20 이고, 박리 강력 3 ㎏/㎝ 이상, 및 다섬 교직포 (교직 1 호, 이하 동일) 에 대한 습윤시, 하중 4 ㎪, 200 ℃, 60 초간의 조건에 있어서의 가열 가압시의 색이행성 평가의 오염용 그레이 스케일을 사용한 색차 급수 판정이 4 급 이상인 입모풍 인공 피혁이다. Disclosed is a napped artificial leather including: a non-woven fabric containing polyester fibers having an average fineness of 0.07 to 0.9 dtex; and an elastic polymer applied in the non-woven fabric, wherein the polyester fibers contain 0.5 to 10 mass% of a dark color pigment, the napped artificial leather has a napped surface on which the polyester fibers on at least one side thereof are napped, and the napped surface has a lightness L* value based on the L*a*b* color system, of ≤ 20, and the napped artificial leather has a peel strength of 3 kg/cm or more, and a grade of color difference, determined using a Grey scale for assessing staining in an evaluation of color migration to a multifiber adjacent fabric (co-woven fabric No. 1; the same applied to the following) during pressurization under heating in a wet state under a load of 4 kPa at 200°C for 60 seconds, of 4 or more.
