The invention provides breathable composite leather, a manufacturing method thereof and an automotive interior. The composite leather comprises a 3D fabric structure and a resin skin structure which are connected in a stacked mode. The resin skin structure comprises a TPU supporting layer, a skin layer and a surface treating agent layer which are sequentially arranged on the surface of one side of the 3D fabric structure in a stacked mode, the skin layer and the TPU supporting layer are connected in a composite mode, and the TPU supporting layer is selected from the shore hardness ranging from 70 HA to 100 HA and the thickness ranging from 0.3 mm to 0.8 mm in a combined mode; wherein the resin skin structure is provided with a plurality of air holes penetrating through the whole thickness of the resin skin structure, the opening area of each air hole is smaller than or equal to 20 mm < 2 >, and the distance between every two adjacent air holes is larger than or equal to 3 mm. The open pore area of the air holes of the composite leather can reach 70%, so that the composite leather has high air permeability and high tensile property and tear resistance at the same time.
本发明提供了一种透气性复合皮革及其制造方法、汽车内饰,复合皮革包括层叠连接的3D织物结构和树脂表皮结构;所述树脂表皮结构包括在所述3D织物结构的一侧表面依次层叠设置的TPU支撑层、表皮层和表面处理剂层,所述表皮层与所述TPU支撑层复合连接,所述TPU支撑层在邵氏硬度70HA~100HA、厚度0.3mm~0.8mm中组合选取;其中,所述树脂表皮结构上设置有多个贯通其整个厚度的透气孔,且单个所述透气孔的开孔面积小于或者等于20mm2,相邻两个所述透气孔之间的间距大于或者等于3mm。本发明的复合皮革透气孔的开孔面积占比可达到70%,因此,能够在具有高透气性的同时具有高的拉伸性能和抗撕裂性能。
