Kind of multi-layer artificial leather and a preparation method therefor, an automotive seat and an automobile

A preparation method for artificial leather, comprising the steps of:

• (a) applying a weaving process, the weaving process comprising:
• adopting at least two groups of warp yarns and weft yarns, and weaving each group of warp yarns and weft yarns into a monolayer structure to form at least two monolayer structures, wherein each of the monolayer structures is woven with some of the warp yarns and/or weft yarns in such layer or with some of the warp yarns and/or weft yarns in one or more other layers to form a number of connecting points, such that at least two monolayer structures arranged in an orderly manner as two laminates are connected with each other by the weaving process, thereby forming a multi-layer integrated base fabric;
• (b) bonding the base fabric and a resin layer together to form an artificial leather;
• and
• (c) punching holes in the artificial leather to form multiple air vent holes distributed in the resin layer and the base fabric in the direction of thickness.
