A method for manufacturing an artificial leather comprising: preparing two or more types of island-in-sea conjugate fibers, each comprising a sea component and an island component, wherein island components of the two or more types of island-in-sea conjugate fibers are two or more types of polyester polymers having different numbers of repeat units of -CH 2 -; forming a non-woven fabric using the two or more types of island-in-sea conjugate fibers; impregnating a polymeric elastomer in the non-woven fabric; passing the polymeric elastomer-impregnated non-woven fabric through a hot roller to compress the polymeric elastomer-impregnated non-woven fabric; and eluting the sea components from the two or more types of island-in-sea conjugate fibers to form an ultrafine non-woven fabric, wherein a temperature of the hot roller is maintained within a range of 80 to 200°C, and, the artificial leather has a recovery rate of 80% or more , wherein recovery rate is measured using a VMS PV-Series apparatus produced by G&P Technology as follows: an initial load of 900 gf/cm 2 is applied to a spherical indenter and the load is maintained for 30 seconds; subsequently, 30 seconds after the initial load is removed, a maximum thickness (T1) of the artificial leather is measured to a level of 1/1,000 mm; the initial load is applied for 30 seconds again and a minimum thickness (T2) is measured to a level of 1/1,000 mm; subsequently, 30 seconds after the initial load is removed, the thickness (T3) of the artificial leather is measured to a level of 1/1,000 mm, and, a recovery rate is calculated using the following equation, Recovery rate % = T 3 − T 2 / T 1 − T 2 × 100 . preparing two or more types of island-in-sea conjugate fibers, each comprising a sea component and an island component, wherein island components of the two or more types of island-in-sea conjugate fibers are two or more types of polyester polymers having different numbers of repeat units of -CH 2 -; forming a non-woven fabric using the two or more types of island-in-sea conjugate fibers; impregnating a polymeric elastomer in the non-woven fabric; passing the polymeric elastomer-impregnated non-woven fabric through a hot roller to compress the polymeric elastomer-impregnated non-woven fabric; and eluting the sea components from the two or more types of island-in-sea conjugate fibers to form an ultrafine non-woven fabric, wherein a temperature of the hot roller is maintained within a range of 80 to 200°C, and, the artificial leather has a recovery rate of 80% or more , wherein recovery rate is measured using a VMS PV-Series apparatus produced by G&P Technology as follows: an initial load of 900 gf/cm 2 is applied to a spherical indenter and the load is maintained for 30 seconds; subsequently, 30 seconds after the initial load is removed, a maximum thickness (T1) of the artificial leather is measured to a level of 1/1,000 mm; the initial load is applied for 30 seconds again and a minimum thickness (T2) is measured to a level of 1/1,000 mm; subsequently, 30 seconds after the initial load is removed, the thickness (T3) of the artificial leather is measured to a level of 1/1,000 mm, and, a recovery rate is calculated using the following equation, Recovery rate % = T 3 − T 2 / T 1 − T 2 × 100 . an initial load of 900 gf/cm 2 is applied to a spherical indenter and the load is maintained for 30 seconds; subsequently, 30 seconds after the initial load is removed, a maximum thickness (T1) of the artificial leather is measured to a level of 1/1,000 mm; the initial load is applied for 30 seconds again and a minimum thickness (T2) is measured to a level of 1/1,000 mm; subsequently, 30 seconds after the initial load is removed, the thickness (T3) of the artificial leather is measured to a level of 1/1,000 mm, and, a recovery rate is calculated using the following equation, Recovery rate % = T 3 − T 2 / T 1 − T 2 × 100 . <EOS>
