The invention provides artificial leather with a multi-layer structure and a preparation method thereof, a vehicle seat and a vehicle. The artificial leather comprises a resin layer as a surface and a base cloth connected with the resin layer as a substrate; the base cloth comprises at least two stacked single-layer weaves, and each single-layer weave is formed by mutually weaving warp yarns and weft yarns of the respective layer; each single-layer weave is formed into a plurality of connecting points by mutually weaving part of warp yarns and/or weft yarns of the layer and part of weft yarns and/or warp yarns of the other layer or multiple layers, so that at least two stacked single-layer weaves are connected together in a weaving manner to form the integrated base cloth with a multi-layer structure; and a plurality of vent holes penetrating through the resin layer and the base cloth in the thickness direction are formed in the artificial leather. Even if the artificial leather is applied to punching of the vehicle seat, the tensile strength, tear resistance and other mechanical properties of the artificial leather can still be kept, use is basically not affected, and therefore the comfort level of a driver and passengers can be improved.

    本发明提供了一种具有多层结构的人造革及其制备方法、车辆座椅及车辆,人造革包括作为表面的一树脂层和与之相连的作为基底的基布,基布包括至少两个层叠设置的单层组织,各单层组织由各自层的经纱和纬纱相互编织而成,每个单层组织通过其层的部分经纱和/或纬纱与其他一层或多层的部分纬纱和/或经纱相互编织形成多个连接点,从而使至少两个层叠设置的单层组织通过编织的方式连接在一起,形成具有多层结构的一体式基布,所述人造革上设有在厚度方向上贯穿所述树脂层和所述基布的多个通气孔。本发明的人造革即使应用于车辆座椅对其进行打孔,其抗拉伸强度和抗撕裂等力学性能仍能够保持,基本不会影响使用,从而能够提高司乘人员的舒适度。
