[0021] The following embodiments further illustrate the space leather fabric for backpacks of the present utility model in conjunction with the accompanying drawings.

[0022] This implementation mode provides a space leather fabric for backpacks. Taking the surface facing the inner side of the backpack as the inner side and the other side as the outer side, this space leather fabric sequentially includes a waterproof inner layer 1, a plastic connection layer 2, a space leather layer 3, and an antioxidant outer layer 4 from the inside to the outside; on the side of the waterproof inner layer 1 facing the plastic connection layer 2, there are several rubber connection posts 11. The rubber connection posts 11 are frustum-shaped, and the side with a smaller diameter is adhered to the waterproof inner layer 1 through acrylic emulsion; on the side of the plastic connection layer 2 facing the waterproof inner layer 1, there are several through holes 21 corresponding in shape, size, and position to the rubber connection posts 11. The side with a smaller diameter of the through hole 21 faces the waterproof inner layer 1; the waterproof inner layer 1 and the plastic connection layer 2 are connected by socketing between the rubber connection posts 11 and the through holes 21, and the plastic connection layer 2, the space leather layer 3, and the antioxidant outer layer 4 are sequentially fixedly connected through adhesives.

[0023] Preferably, the waterproof inner layer 1 is a PVC Oxford cloth layer with a thickness of 0.15 - 0.255 mm. The PVC Oxford cloth layer of this waterproof inner layer 1 is purchased from Zhejiang Xinyu Textile Co., Ltd., and the product name is 300D PVC Oxford cloth.

[0024] Preferably, the plastic connection layer 2 is a polypropylene layer with a thickness of 4.2 - 5 mm. The polypropylene layer of this plastic connection layer 2 is purchased from Shandong Baihao Rubber and Plastic Products Co., Ltd., and the product name is polypropylene board.

[0025] Preferably, the height of the frustum-shaped rubber connection posts 11 is 0.5 mm less than the thickness of the plastic connection layer 2, and the radius difference between the upper and lower bottom surfaces of the rubber connection posts 11 and the through holes 21 is 0.5 mm.
