By laminating a polyurethane resin skin layer on the surface of the woven brushed fabric by the paper method, synthetic leather with a voluminous feel for the length of the brushed fabric can be obtained, and air is contained inside the brushed fabric. Therefore, a wrinkle can be easily formed on the polyurethane resin skin layer, and a synthetic leather having an appearance very similar to natural leather can be obtained. However, in this brushed portion between the skin layer and the back surface of the brushed cloth, there is no luxurious feeling because there is no planar connection only in the thickness direction. Further, by a wet method, a polyurethane resin diluted with DMF is applied so as to penetrate into the raised portion of the woven brushed fabric, and introduced into water to replace water and DMF to form a microporous layer. By laminating the resin skin layers, synthetic leather with a voluminous feel can be obtained. However, the time required for production increases the production cost of synthetic leather.
