Embodiment 1
[0019] A method for preparing high-strength wear-resistant leather, comprising the following steps:
[0020] (1) Retanning: Put the split and trimmed leather after tanning in chrome tanning agent for re-kneading, drum tanning at 41°C for 5 hours, take it out, rinse it with deionized water, and promote collagen fibers in the leather Synthetic to make the leather texture uniform and soft to obtain retanning material;
[0021] (2) Primary drying: put the retanning material in an oven and dry at 37°C until the water content is 43%, so that the water content can be rapidly reduced, the porosity of the leather surface can be reduced, the uniformity of the leather can be improved, and the Temperature to 28°C, continue to dry until the moisture content is 20%, so that the moisture inside the leather material will slowly lose, increase the mesh structure and fiber strength inside the leather material, make the leather breathable and warm, comfortable to wear, and get a dry material onc...
Embodiment 2
[0028] A method for preparing high-strength wear-resistant leather, comprising the following steps:
[0029] (1) Retanning: put the split and trimmed leather after tanning in chrome tanning agent for re-kneading, drum tanning at 42°C for 5 hours, take it out, rinse it with deionized water, and promote collagen fibers in the leather Synthetic to make the leather texture uniform and soft to obtain retanning material;
[0030] (2) Primary drying: put the retanning material in an oven and dry at 38°C until the water content is 44%, so that the water content can be quickly reduced, the porosity of the leather surface can be reduced, and the uniformity of the leather can be improved, and then the water content can be reduced. Temperature to 29°C, continue to dry until the water content is 21%, so that the moisture inside the leather material will slowly lose, increase the mesh structure and fiber strength inside the leather material, make the leather breathable and warm, comfortable...
Embodiment 3
[0037] A method for preparing high-strength wear-resistant leather, comprising the following steps:
[0038] (1) Retanning: put the split and trimmed leather after tanning in chrome tanning agent for re-kneading, drum tanning at 43°C for 6 hours, take it out, rinse it with deionized water, and promote collagen fibers in the leather Synthetic to make the leather texture uniform and soft to obtain retanning material;
[0039] (2) Primary drying: put the retanning material in an oven and dry at 39°C until the water content is 45%, so that the water content can be quickly reduced, the porosity of the leather surface can be reduced, and the uniformity of the leather can be improved, and then the water content can be reduced. Temperature to 30°C, continue to dry until the moisture content is 22%, so that the moisture inside the leather material will be slowly lost, the mesh structure and fiber strength inside the leather material will be increased, the leather material will be breat...
