Leather is a durable and flexible material created by tanning animal rawhides, mostly cattle hide. It can be produced at manufacturing scales ranging from cottage industry to heavy industry.Leather is used to make various goods including footwear, automobile seats, clothing and furniture. It is produced in a wide variety of types and styles and decorated by a wide range of techniques.
The earliest record of leather artifacts dates back to 2200 BC.The leather manufacturing process is divided into three fundamental subprocesses: preparatory stages, tanning, and crusting. A further subprocess, surface coating, can be added into the leather process sequence, but not all leathers receive surface treatment. The preparatory stages are when the hide is prepared for tanning. Preparatory stages may include: liming, deliming, hair removal, degreasing, bleaching, and pickling.Tanning is a process that stabilizes the proteins of the raw hide so it does not putrefy, making it suitable for a wide variety of end applications. The principal difference between raw and tanned hides is that raw hides dry out to form a hard, inflexible material that, when rewetted, will putrefy, while tanned material dries to a flexible form that does not become putrid when rewetted.Many tanning methods and materials exist. The typical process sees tanners load the hides into a drum and immerse them in a tank that contains the tanning "liquor". Crusting is a process that thins and lubricates leather. It often includes a coloring operation. Chemicals dded during crusting must be fixed in place. Crusting culminates with a drying and softening operation, and may include splitting, shaving, dyeing, whitening or other methods.
The hides soak while the drum slowly rotates about its axis, and the tanning liquor slowly penetrates through the full thickness of the hide. Once the process achieves even penetration, workers slowly raise the liquor's pH in a process called basification, which fixes the tanning material to the leather. The more tanning material fixed, the higher the leather's hydrothermal stability and shrinkage temperature resistance.Today, most leather is made of cattle hides, which constitute about 65% of all leather produced. Other animals that are used include sheep, about 13%, goats, about 11%, and pigs, about 10%. Obtaining accurate figures from around the world is difficult,
