the utility model provides a wear-resisting leather base cloth, includes the base cloth layer, the top surface fixedly connected with first adhesive linkage of base cloth layer, and the top surface fixedly connected with PVC coating of first adhesive linkage, the bottom surface fixedly connected with second adhesive linkage of base cloth layer, the top surface of first adhesive linkage and the bottom surface of second adhesive linkage respectively fixed mounting have first wearing layer, and the top surface of top first wearing layer and the bottom surface of below first wearing layer still respectively fixedly connected with second wearing layer.

Preferably, the first wear-resistant layer is a polyamide fiber layer.

Preferably, the polyamide fiber layer has a thickness of between 0.3 mm and 0.4 mm.

Preferably, the second wear-resistant layer is composed of a polycarbonate polyol polyurethane coating and a organosilicon coating, and the organosilicon coating is fixedly connected to the surface of the polycarbonate polyol polyurethane coating.

Preferably, the thickness of the polycarbonate polyol polyurethane coating is between 1.5 and 2 millimeters.

Preferably, the thickness of the silicone coating is between 0.1 mm and 0.2 mm.

Compared with the prior art, the utility model has the following beneficial effects:

according to the utility model, the first wear-resistant layer and the second wear-resistant layer are added on the traditional leather base cloth, and the first wear-resistant layer formed by the polyamide fiber layer can greatly improve the wear resistance of the leather base cloth because the polyamide fiber is the wear-resistant preferential fiber in all textile fibers, and the second wear-resistant layer formed by the polycarbonate polyol polyurethane coating and the organosilicon coating can further improve the wear resistance of the leather base cloth through the wear resistance of the polycarbonate polyol polyurethane coating and the organosilicon coating, and the organosilicon coating arranged on the surface of the leather base cloth can also improve the waterproof and air permeability of the leather base cloth, so that the leather base cloth has a double-layer wear-resistant structure in the use process by utilizing the first wear-resistant layer and the second wear-resistant layer, the aim of wear resistance of the leather base cloth is achieved in long-time use, the problem that the leather base cloth is easy to wear is avoided, and the service life of the leather base cloth is further prolonged.
