Lubrication influences the properties of leather. It's an important process for either changing the appearance of the leather, making it softer, or waterproofing it. Lubrication influences the leather's original properties. Noticeable changes can be seen in its elasticity, flexibility, softness, tensile strength, and water permeability. Vegetable fats (such as coconut oil or olive oil), animal fats, or synthetic fats are often used as fatliquoring agents.
