How do Ugg boots?
Nobody saw it coming, but Ugg Boots have certainly taken the world by storm and become a huge fashion craze. All the world that someone is using them! Ugg Austrailians know that means "ugly" but these woolly sensations are still everywhere. Wondering exactly how Ugg boots are made and just what makes them so comfortable?
Genuine Ugg Boots are made of quality materials, including sheepskin hide. You can buy Imitation Ugg Boots almost anywhere, but only the real deal provides the comfort and durability promised by Ugg. If not manufactured in Australia, then they are not authentic. Ugg Boots are just not made in China, so do not be fooled. Buying Ugg-style boots that are not a genuine willingness to go with boots that are much lower in quality. Translation: uncomfortable and smelly.
Warm in winter and cool in summer, Ugg boots are made from genuine Australian sheepsking double-sided, usually from Australia Merino sheepskin. The highest quality in everything! Save a few dollars will give a bit of synthetic fiber that is not the same.
Some people wonder if the animals are harmed during the production of Ugg boots. The short answer is, the sheep is slaughtered. BUT, that sheep would be slaughtered for meat to feed the People who never really is sacrificed to obtain sheepskin. Sheep farmers obtain a secondary gain for the sale of skins, in addition to the meat. Therefore, understand that the realization of Ugg Boots does not directly harm the sheep.
Sheepskins has to be preserved properly before they can be processed within boots. Tanneries use large vessels called paddles, that hold anywhere from 3,000 to 15,000 liters of salt water and slowly swish the skins around inside. This is a gentle process, which takes about 10 days to get the skins tanned and ready to be cut properly to Ugg.
Step 1. Tanning / Processing
The first step in tanning or processing of sheepskin is to "soak up", which takes about 16 hours to complete. During this process, the skins are rinsed in water cold to remove any excess salt or dirt from the wool and skin. This process is carried out overnight soak in a tub of cold water.
The next step in the tanning process is called "scrapers." This part of the process uses a fleshing machine which removes any excess fat and muscle tissue from the bottom of sheepskins. This part of the process is essential to allow faster penetration and full of chemicals in the later stages of processing, especially during the pickling and tanning stages.
After scrapers is "scrubbed." This 30-45 minute segment of the process uses surfactants at high temperatures (around 38 degrees Celsius) and is responsible for removing dirt and lanolin (grease) of wool.
"Stripping" of the Skin sheep then takes about 16 hours. Before the sheepskin can be tanned, they have to be) pickled. Pickling means soaking the skins in an acid solution and salt. Add salt prevents any potential swelling of the skins by the acid. It is important to lower the internal pH of the skins to somewhere between 2.8-3.0, which allow the tanning agent to properly penetrate the skin.
The 16-hour "Tanning" step involves using chromium salts which form cross-links with collagen, which helps stabilize the structure of the skin and preventing putrefaction or rotting. This step is carried out at room temperature, about 25 degrees Celsius, and around a pH of 2.5-3.0. Once the tanning agent (chromium) penetrates the skin, the process stops and the chrome is fixed to the collagen raisng pH to 3.6 with sodium bicarbonate and heating the skins to between 35-40 degrees Celsius. Thus, the shrinkage temperature of skin is raised to between 60-100 degrees Celsius.
Next comes "Wool Dyeing" or "Grease." This may take 3-4 hours to complete. After the skin is tanned, the wool can be dyed any of a variety of colors. Wool dyeing needs to be done at about pH 4.5-6 and 60-65 degrees Celsius. Special "reservations agents skin "should be added to keep the wool dye staining the skin. Once the dye is stable, the pH is reduced to around 4.0 to fix the dyes for wool, and oil (emulsified oil) is added to the solution. Fatliquors are part of leather manufacturing that help to lubricate the collagen fiber and allow them to move flexibly and freedom once the skin is dry. This makes the skin soft to the touch.
Drying of the skins then takes 4-24 hours. Forced air dryers are used with skins stretched across a frame. Drying occurs at 50-80 degrees Celsius.
Dry cleaning should then take place over the next 4-24 hours. Either a white spirit (a high boiling petroleum fraction) or perchloroehtylene is used to remove the natural fat or grease left on the skin.
After the final disposal of fat skin, "Pelt, dyed" or "Syntanning" comes next. Back in the palette (The soaking vessel), the skins are dyed in cooler temperature dyes (less than 30 degrees Celsius). This minimizes staining of the wool. After skin the dye is complete, involves the use syntanning synthetic tanning agent for hides added fullness and firmness. Finally, the skins are dried once again.
Step 2. Finish
After the long tanning process is complete, the final finish is done to the skins can be used for Ugg boots.
The skins must be conditioned to approximately 20% humidity. Layout is the process by which the skin is softened and stretched, and a "diaper" area is added to the skin.
Final "combing", "Ironing" and "cut" and then performed to remove tangles, burrs, or grass seeds that may remain in the wool. The wool is stretched with an iron to remove the natural ridge. Finally, a cutting machine creates a lot of wool uniform a desired length (usually 12-15 mm).
Step 3. Manufacturing
A press 'click' is used to cut individual panels of the skins. After being cut to size panels are sewn with industrial sewing machines special. The soles are then glued to the high boot, and finally, Ugg boots are ready for you to purchase.
