With the development of the times, the demand of human beings for leather products in life is increasing. In the development process of leather tanning technology, chrome tanning still takes a leading position, and has the advantages of time saving, economy, easy operation and the like, and the finished leather of the method has excellent physical and mechanical properties and sensory properties. However, the chromium tanning agent cannot be completely absorbed by collagen fibers in the tanning process, so that 20-35% of chromium in the chromium tanning agent is discharged along with waste water, the chromium can affect the normal growth of fishes and land plants in a water body, particularly hexavalent chromium has a strong carcinogenic effect on a human body, and the health of the human body is seriously harmed. Moreover, the chromium-containing wastewater is difficult to treat and high in cost, and the wastewater treatment cost is increased for tanning enterprises.
Aiming at the problems, the plant tanning agent which can be degraded, is non-toxic and harmless is adopted for tanning. The vegetable tanning leather is leather tanned mainly by a vegetable tanning agent, and has the advantages of compact and firm leather body, low extensibility and good formability. And the vegetable tanning agent is a natural organic material, belongs to renewable resources and has small pollution to the environment. However, the combination mode of the vegetable tanning agent and the skin collagen is mainly combined by hydrogen bonds, so that the acting force is small and the vegetable tanning agent is easily damaged by external force. And the vegetable tanning agent cannot come into contact with the iron, otherwise the vegetable tanned leather becomes an irreversible grey-black color. In addition, the water resistance of the vegetable tanned leather is insufficient, the vegetable tanned leather is thin and flat and is not wear-resistant, and the production requirements of the leather for soles cannot be met.

The method comprises the steps of iron removal, pretanning, oil adding and the like, and in the vegetable tanning method, the vegetable tanning agent can react with iron under an acidic condition to generate black extremely stable iron tannate, so that the quality of vegetable tanned leather is greatly influenced. The iron removal process is added, and the effect of iron on the vegetable tanned leather can be eliminated by adding diethylenetriaminepentaacetic acid (DTPA) and N-Benzoylphenylhydroxylamine (BPHA), because iron, DTPA and BPHA generate stable complexes under the acidic environment with chloride ions, and the stable complexes are removed with water washing. In the vegetable tanning method, because the vegetable tanning leather has insufficient water resistance, is thin and not wear-resistant, the vegetable tanning agent is easy to run off in the tanning process, and the tanning coefficient is reduced. The water resistance and the wear resistance of the vegetable tanned leather can be improved by adding the sodium-based nano montmorillonite, the water-soluble graphene oxide and the oil in the pre-tanning and oil adding processes. The sodium-based nano montmorillonite is filled into vegetable tanning leather in the tanning process to increase the thickness of the vegetable tanning leather, so that the wear resistance of the vegetable tanning leather is changed. The water-soluble graphene oxide is an amphiphilic structure, hydrophilic groups and leather fibers are combined on the surface of the leather, hydrophobic groups are regularly distributed and arranged to form a hydrophobic membrane, oil has super-hydrophobicity, the property of the hydrophobic membrane formed by the water-soluble graphene oxide can be enhanced, the defect of insufficient water resistance of vegetable tanning leather can be improved through tanning, and the production requirement of the leather for soles is met.

TABLE 2 evaluation results of the effect of the waterproof, abrasion-resistant and environment-friendly vegetable tanning shoe sole leather
From the results of the evaluation of the effects, it was found that the addition of diethylenetriaminepentaacetic acid (DTPA) and N-Benzoylphenylhydroxylamine (BPHA) has a significant effect on the removal of iron during tanning. The sole leather obtained by adding the sodium-based nano montmorillonite in the tanning process has good wear resistance. However, under the condition of not adding sodium-based nano montmorillonite, the tanned sole leather has poor wear-resisting effect, so that the finished product is easy to wear in the testing process. The sole leather obtained by adding the water-soluble graphene oxide and the oil in the tanning process has good water resistance, and the washing resistance of the product is enhanced.
It is understood that various other changes and modifications may be made by those skilled in the art based on the technical idea of the present invention, and all such changes and modifications should fall within the protective scope of the claims of the present invention.
