Ugg Boots originated from Australia and are typically made of twin-faced sheepskin with fleece inside, tanned surface outside and a synthetic sole. From Australians’ point of view, Ugg means “ugly” but Ugg Boots become an essential fashion item among the celebrities, such as Blake Lively, Vanessa Hudgens, Emma Watson, Hilary Duff, Taylor Momsen, Kate Upton, Leighton Meester and so on.
Genuine Ugg Boots are so comfortable with the feeling that they are warm in winter and cool in summer. These Ugg Boots are made from high quality materials, which are Australian double-faced sheepskins. Making a pair of Ugg Boots by hand is time-consuming and complicated, which requires several days to make a pair of genuine Ugg Boots. The steps are explained briefly below.
The sheepskins are rinsed in fresh cold water in order to remove any salt or dirt from the wool for about 16 hours.
The sheepskins are put under the fleshing machine to take away any excess fat and muscle tissue from the underside of the sheepskins.
Surfactants are used under high temperatures to remove any remaining dirt and lanolin from the wool. This process is held for around 30-45 minutes.
Another 16 hours are needed to soak the skins in a solution of acid and salt allowing the tanning agent to penetrate the sheepskin properly.
Tanning process can now be undertaken at room temperature for 16 hours. This involves using chromium salts to help stabilizing the skin structure and preventing rotting.
The sheepskin can be dyed with any colours after the skin is tanned, and it takes around 3-4 hours to complete this step.
The sheepskin is dried using forced air dryers for around 4-24 hours. In addition, another 4-24 hours are required to dry-clean the sheepskin.
A final removal of pelt grease is undertaken to minimise staining of wool. Synthetic tanning agents are then used to make the pelts to be more firm and full. Lastly, the sheepskin is dried again.
In order to remove any tangles, burrs or grass seeds, an iron is used to straighten the wool.
Clipping machine is used to create wool pile at a desired thickness (normally 12-15mm). Individual panels are cut from the sheepskins using clicking press. The panels are sewn together using the sewing machines and the soles are glued to the boot upper.
