As we all know, UGG boots are made of sheepskin, they bring us warm and conformity in winter. Have you ever thought of the process of making UGG boots? If you do not, this text will show you to help you get more information about your favorite UGG.

Step 1: Tanning.
Sheepskin must be saved for a long time before they can be adopted on boots. Large vessels that hold from 3,000 to 15,000 liters of salt water anywhere are used in tanneries. Skins swish slowly inside. This is absolutely a low process lasting around 10 days till the hides are tanned properly that is ready to be cut for UGG boots.
Let’s pay attention to its detailed process which has 7 parts. The first part is called Soaking. Rinse skins completely in a vat of cold water in order to eliminate unnecessary salt or dirt on them, which lasts around 16 hours and is suggested to be done all the night through.

The second part is named Fleshing which is significant for later processes such as rapid and complete penetration of chemicals. This stage is mechanical completely. Fleshing machine wipes any redundant fat and muscle tissue off from interior sheepskin. There is no doubt this assures comfort and also health on boots strongly. The most important part lies in pickling and tanning stages of later.
The third part comes to Scouring which should be the most professional stage in its whole process. Surfactants of high temperature (about 38 degrees Celsius) purify dirt and lanolin from the sheepskin completely.
The fourth part refers to Pickling that takes about 16 hours. It is essential in solving acid and salt in sheepskin by soaking it. Salt can be considered as a great assistant in preventing swelling on sheepskin because of the acid. Workers will make sure low the PH of sheepskin to between 2.8 and 3.0 which is helpful for tanning agent to penetrate the skin.

The fifth part is Tanning now which should be operated carefully, especially caring for the demanded temperature. Adding chromium salts that is essential in forming cross-links with the collagen is helpful to stabilize the skin structure, preventing putrefaction of rotting. As soon as tanning agent crosses the skin, stop this process at once. Use sodium bicarbonate and heat sheepskin to 35-40 degrees Celsius. Are you interested why UGG boots are proper for each season? Here is the answer. This process is done at temperature of about 25 degrees Celsius. Due to the shrinkage temperature on sheepskin, it can be raised to 60-100 degrees Celsius in future.
The sixth part comes to Sheepskin Dyeing. To be honest, this is a simple stage can be perceived on its name. However, it is complicated in grasping the temperature indeed. 60-65 degrees Celsius is needed while dyeing. Pelt reserve agents must be added in order to keep dye stale. After this, fat liquor is added to help to lubricate the collagen fiber which allows them to move more flexibly. Have you found the answer why leather feels so soft and elastic now?

The seventh part of is easy, yet has several stages. Forced air dryers are needed to drying skins. Either a white spirit or perchloroehtylene is used on Dry Cleaning.
Step 2: Finishing.
The final part is finishing after which skins can be used to make UGG boots. Condition the skins to about 20% moisture in content in order to make sure it becomes soft and elastic. What’s more, an interior piece of sheepskin is added to the pelt which explains twin-faced sheepskin on those stylish boots. You will never see bad quality on UGG boots because their sheepskin has been straightened by an iron to remove the natural crimp.
Step 3: Producing.
Kinds of individual panels are cut from the skins which are sewn together by professional machines. The soles are glued to boot upper. Now, you can purchase them!
