The leather is essentially tanned after following a long procedure: Before anything else, the animal leather is obtained. This is done before the heat of its body leaves the tissues. Salt is applied so that the skin does not rot and so that bacteria does not begin to grow.
Soaking: This process is where the hides are soaked in clean water to get rid of all the salt present in the hide. This also increases the moisture in the hide and further helps it to cure.
Liming: As the name suggests, Lime water is used to remove the grease, keratin matter, and hair.
Unhairing and Scudding: The hair is removed, first with the help of machinery and afterward, with the help of a manual technique using a knife.
Deliming and Bating: Since the limewater is no longer required, deliming is carried out. The hide is washed thoroughly to bring down the pH of the collagen after which Batting, which is an additional method of removal of proteins is followed. This eliminates all the fat, protein, and other waste.
Pickling: Once all the previous steps are followed, salt is used to treat the hide. This makes the fibers of the hide more willing to accept tanning. After following this process, you’re left with leather which is used to make boots, bags, jackets and a number of items.
