Abstract: Microfiber leather veneering usually use a release paper transfer process, while leather finishes use a water-based spray process. The latter has a better surface effect and environmental performance. In this paper, the leather finishing process and the dry veneering process are applied to the modified and unmodified base fabrics respectively. The paper systematically analyzes the application effect of the finishing process in microfiber leathers through the research on their sanitary properties such as air permeability and moisture permeability, as well as their mechanical properties such as peeling strength, tear strength and elongation at break. Research indicated that the finishing process is superior to the veneering process in terms of hygienic performance, and its physical strength also reaches the standards, and can be applied to the veneering of microfiber leather.
