Embodiment 1

[0074] A processing technology for leather products, comprising the following specific steps:

[0075] A1. Skin selection:

[0076] Select an adult mule hide;

[0077] A2. The first soaking:

[0078] Place the selected mule skin in a wooden barrel and soak it in warm water;

[0079] A3. De-meat:

[0080] Take out the soaked rawhide, and scrape off the fat and meat inside;

[0081] A4, the second soaking:

[0082] Place the raw hides that have been de-fleshed in wooden barrels and soak them in warm water for 48 hours;

[0083] A5. Liming for the first time:

[0084] The rawhide soaked in step A4 is placed in the cement pool, smeared on the meat surface with lime, and left standing;

[0085] A6. Hair removal:

[0086] Use a spatula to remove the pickled ash skin;

[0087] A7, the second liming:

[0088] Place the rawhide processed in step A6 in the cement pool, smear it on the meat surface with lime, and let it stand;

[0089] A8, peeling:

[0090] Stretch the skin s...

Embodiment 2

[0133] On the basis of Example 1, in step A2, the soaking time is 3 days. The leather produced by this method does not use any chemical raw materials, does not cause any adverse effects on the environment, and does not cause any physical damage to the craftsmen who make the leather. damage.

Description

technical field [0001] The invention belongs to the technical field of leather products; in particular, it relates to a processing technology of leather products. Background technique [0002] During the processing of the stock leather, the ancient method is used for reference. The heat, time, and strength are all controlled manually. Failure to do one of the links will affect the final quality of the leather after molding. The leather output of this method tannin is low, and the success rate is low. Contents of the invention [0003] In order to overcome the deficiencies in the background technology, the present invention proposes a leather product processing technology, without adding any chemical raw materials, so that the prepared leather has the characteristics of air permeability and water impermeability, and is wear-resistant and tough. [0004] In order to achieve the above object, the present invention is achieved through the following technical solutions: [00...
