How can fresh sheepskin be treated to become leather?

Need to go through a series of complicated processes.

The cooking process of rawhide is very complicated, which requires tanning, pickling and other technical treatments, and its process flow is as many as dozens of processes:

It takes half a month to twenty days to complete the whole process, such as soaking in water, removing meat, degreasing, unhairing, alkali soaking, swelling, deashing, softening, acid soaking, tanning, slicing, flat cutting, retanning, neutralizing, dyeing, oiling, filling, drying, finishing and painting, and finally it becomes finished leather, commonly known as cooked leather.

Sheepskin is the most mature fur, and the fur of dogs and many animals can be processed. The most precious fur is fox, roe deer, mink, leopard, tiger skin and so on. Cooked fur is further processed into warm clothes such as fur jackets and coats, and can also be made into daily necessities for the elderly such as leather plates.

Extended data:

Animal skins with fur must also be processed into soft and shiny cooked fur through complicated processes such as soaking in water with mild corrosive agent, tanning and nitration. Ripe skins are mostly made from skins of cattle, mules, horses and donkeys, and cowhide is the best. Ripe leather has the characteristics of softness, tenacity and good air permeability, and is widely used in the processing of leather shoes, suitcases, suitcases, belts, soft parts for chariots and horses, vehicle tires and so on.

Sheepskin hardens because there is a lack of oil in it. Generally speaking, sheepskin products cannot be washed with water. If washed with water, the oil in sheepskin will be taken away by water, and sheepskin will lose oil. The softness of sheepskin is inseparable from oil. If you lose the oil, the sheepskin will become hard, and the clothes will be strong and easily printed.
