What is the process of converting skin to leather?
Tanning (leather)
- Tanning is the process of treating skins and hides of animals to produce leather.
- Tanning hide into leather involves a process which permanently alters the protein structure of skin, making it more durable and less susceptible to decomposition, and also possibly coloring it.
How leather is made step by step?
The leather manufacturing process is divided into three sub-processes: preparatory stages, tanning and crusting. All true leathers will undergo these sub-processes. A further sub-process, surface coating may be added into the sequence. The list of operations that leathers undergo vary with the type of leather.
How leather is formed?
Leather is a strong, flexible and durable material obtained from the tanning, or chemical treatment, of animal skins and hides to prevent decay. The most common leathers come from cattle, sheep, goats, equine animals, buffalo, pigs and hogs, and aquatic animals such as seals and alligators.
What is used to convert skin and hides into leather?
tanning, chemical treatment of raw animal hide or skin to convert it into leather. A tanning agent displaces water from the interstices between the protein fibres and cements these fibres together.
How is leather made smooth?
Sanding leather involves applying an abrasive paper on a rotating roller to the surface (grain side) or reverse (flesh side). This results in a uniform surface. The leather is then called nubuck. If a smooth leather is sanded to make the surface smoother, the tanner also calls this buffing.
Where does most leather come from?

The industry defines hides as “skins” of large animals e.g. cow, buffalo; while skins refer to “skins” of smaller animals: goat, sheep, deer, pig, fish, alligator, snake, etc.
What is finishing in leather?
Finishing determines the appearance of the final surface of the leather and the surface properties. This includes colouring, waterproofing, wax dressings, but also mechanical processing stages such as ironing or embossing of the leather.

What is the second stage of the leather-making process?
TANNING Now that the hide has been prepared, the second stage in the leather-making process is called tanning and will convert the hides into leather through preserving the material and halting decomposition. To do this, hides need to be loaded into a special tanning drum along with a special tanning solution.
What is leather made from?
Leather can be made from the hide of almost any animal including pigs, sheep, goats and crocodiles. However, the most common hide used is that from a cow. A by-product of the meat and dairy industries, the art of making leather uses hides that would otherwise be destroyed.
