The invention belongs to the technical field of leather, and particularly discloses water-based directly-coated microfiber sofa leather, and a water-based directly-coated microfiber sofa leather production process. The water-based directly-coated microfiber sofa leather is prepared by preparing a microfiber base fabric and a cover, conducting ironing, roll-coating a foaming layer, conducting scalding, coating surface slurry, conducting embossing, spray-coating effect slurry, and conducting milling and oscillation staking to obtain the finished product (microfiber sofa leather). By means of microfiber gray cloth, the sofa leather has a microstructure similar to that of natural leather, overcomes the poor body form part and poor thickness uniformity of genuine leather, has super moisture absorption performance, and has the structure closer to that of genuine leather; in cooperation with the finishing of the genuine leather, the microfiber leather is more environmentally friendly, even has the texture of the genuine leather and has the unique moisture absorption performance and breathability, is higher in firmness and more durable in use, and even has performance on some aspects better than that of the genuine leather; in addition, the finishing process is close to the processing method of the genuine leather, and therefore the water-based directly-coated microfiber sofa leather has the appearance and the internal structure both close to those of the natural leather.
