Abstract: A preparation process of spunlace intertwining type recycled cow leather comprises a material preparation process, a cow leather fiber web forming process, as well as a mixed fiber web forming process, an overlapped web forming process, a base fabric manufacturing process and a cow leather finished product manufacturing process which are sequentially arranged according to a preparation process flow; the base fabric manufacturing process comprises a buffing process, a single-side immersion treatment process and an ironing process which are sequentially arranged for manufacturing the overlapped web into the base fabric; and the single-side immersion treatment process comprises the steps of subjecting a single side of the base fabric to single-side coating treatment of the water-based PU material or the oil-based PU material by adopting an inverted feeding device and using a water-based PU material or an oil-based PU material as a coating so as to form a single-side permeable immersion layer of the base fabric.
