Abstract
A preparation method for artificial leather, includes applying a weaving process. The weaving includes adopting at least two groups of warp or weft yarns, and weaving each group of yarns into a monolayer structure to form at least two monolayer structures. Each of the monolayer structures is woven with some of the warp and/or weft yarns in such layer or with some of the warp and/or weft yarns in another layer 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. The method includes bonding the base fabric and a resin layer together to form an artificial leather; and punching holes multiple air vent holes in the leather distributed in the resin layer and base fabric in the thickness direction.
