It is introduced so as to circulate from the top of the coagulation tank 202 into the water of the coagulation tank 202. The polyupethane blended raw material (CF), which will be a coating layer of synthetic leather, is coated on the mold belt 210 to form a mold. The coating layer 200 of the compound raw material (CF) coated on the mold belt 210 by applying a fiber structure (base cloth, 100), which is a base of synthetic leather, to form a natural leather skin pattern on the skin layer in contact with the belt. While the mold belt penetrates through the water in the coagulation water tank 202 and solidifies the film layer 200 mixed with the base paper 100 and transferred from the mold belt 210 to the film layer 200. Cuticle The entire coating layer 200 is solidified and molded into the porous layer while being kept in the wet process, so that the skin layer having the same pattern as the natural leather has an excellent air permeability as a whole without additional treatment for post skin treatment. The present invention provides a wet-finished polyurethane synthetic leather composed of a base cloth 100 and a combination thereof.
