[0005] Furthermore, the middle layer is a mesh structure, which is composed of a 1-0 / 1-2 / 1-0 / 2-3 / 2-1 / 2-3 / / inlay yarn structure formed by the first yarn and a 2-3 / 2-1 / 2-3 / 1-0 / 1-2 / 1-0 / / inlay yarn structure formed by the second yarn.

[0006] Furthermore, the middle layer includes a first tissue layer, a connecting layer and a second tissue layer, the first tissue layer is composed of a 1-0-1-1 / 1-2-1-1 / / padding yarn tissue formed by the first yarn and a 1-2-1-1 / 1-0-1-1 / / padding yarn tissue formed by the second yarn, the second tissue layer is composed of a 1-1-1-0 / 1-1-1-2 / / padding yarn tissue formed by the fourth yarn and a 1-1-1-2 / 1-1-1-0 / / padding yarn tissue formed by the fifth yarn, and the connecting layer is composed of a 1-0-2-3 / 4-5-3-2 / / padding yarn tissue formed by the third yarn.

[0007] Furthermore, the average fineness of the leather fibers or leather fiber bundles of the first surface layer is smaller than the average fineness of the leather fibers or leather fiber bundles of the second surface layer.

[0008] Furthermore, the thickness of the first surface layer is greater than the thickness of the second surface layer.

[0009] Furthermore, the thickness of the second surface layer is not less than 1.0 mm.

[0010] Furthermore, the middle layer is at least one of plain weave, twill weave, satin weave or woven variation weave.
