Liming is the process of soaking animal hides in a lime solution to remove hair, flesh, and other impurities. This helps to soften the hides and prepare them for further processing.
Deliming is the process of removing the lime from the hides after liming. This is typically done by soaking the hides in an acidic solution to neutralize the lime and restore the pH balance of the hides. Deliming helps to prevent damage to the hides and ensures that they are properly prepared for tanning.

Liming of Hides
Liming is a process used to prepare animal hides for tanning. It involves the removal of hair and fats from the hide using a solution of lime (calcium oxide or hydroxide) and enzymes.
Procedure:
- The hide is soaked in a lime solution for several days to soften the hair and dissolve the fats.
- The hide is then agitated or mechanically removed to loosen the hair.
- The hair is washed away to leave a clean, limed hide.
Purpose:
- Removes hair and fats, making the hide more pliable.
- Opens up the hide's fiber structure, allowing tanning agents to penetrate more easily.
- Disinfects the hide, preventing the growth of bacteria and fungi.
De-liming of Hides
De-liming is the process of removing the lime from the hide after liming. It is necessary to restore the hide's pH balance and prepare it for subsequent tanning steps.
Procedure:
- The limed hide is soaked in a solution of water and a de-liming agent, such as ammonium chloride or ammonium sulfate.
- The de-liming agent neutralizes the lime and releases it from the hide.
- The hide is then rinsed thoroughly to remove any remaining de-liming agent.
Purpose:
- Neutralizes the hide's pH to make it suitable for tanning.
- Tightens the hide's fiber structure, improving its strength.
- Prevents the formation of lime deposits that can interfere with the tanning process.
