Theinvention discloses a preparation technology of sofa leather, and relates to the technical field of preparation of artificial leather. The preparation technology comprises following technological steps: S1, a PU resin coating, a foaming coating and an adhesion coating are prepared; S2, base cloth is pretreated; S3, release paper is uniformly coated with the PU resin coating and then is dried at100-130 DEG C, and a surface film layer is obtained; S4, the surface film layer is coated with the foaming coating and dried at 170-200 DEG C, and a foaming layer is obtained; S5, the foaming layer is coated with the adhesion coating and dried at 150-160 DEG C, and an adhesion layer is obtained; S6, the base cloth is applied to the adhesion layer by hot pressing, rolling is performed after the release paper is stripped, and a finished clothing leather product is obtained. The preparation technology has the effect that the microorganism inhibition effect of the artificial leather is improved. 本发明公开了一种沙发革的制备工艺，涉及人造革制备的
