The invention discloses a kind of anti-twisting leather, which includes the following leather processing steps: step 1, preparation stage: selecting soft leather, removing impurities, degreasing, softening and pickling; step 2, tanning stage: by chemical method To change the leather structure, the main processes are: pre-tanning, main tanning and re-tanning. This kind of anti-twisting leather adopts multiple soaking and impurity removal in the preparation stage, which is convenient to increase the permeability of the leather pores and improve the smoothness of the inner surface of the pores. Through chemical methods, the collagen fibers of animal skins are changed in structure, making them change from leather to leather, improving leather softness, increasing fullness, reducing part difference, changing the surface charge of leather, and promoting uniform dyeing and adhesion properties. Increasing the scientific ratio of sodium bicarbonate, resin, tannin extract and multiple materials can make the leather surface feel more delicate, oily, anti-oxidative, and more resistant to torsion. |
