Nobody saw it coming, but Ugg Boots have definitely taken the world by storm and turn out to be a big fashion craze. Everybody whose anyone is wearing them! Austrailians know that Ugg means “ugly” but these woolly sensations are still everywhere. Wondering exactly how Ugg Boots are made and just what makes them so comfy?
Genuine Ugg Boots are made from the highest high quality supplies, including sheepskin hide. You’ll be able to buy knockoff Ugg Boots practically anywhere, but only the real deal supplies the comfort and durability promised by Ugg. If they’re not made in Australia then they’re not authentic. Ugg Boots are just not made in China, so don’t be fooled. Purchasing Ugg-style boots that are not genuine will leave you with boots which are far inferior in quality. Translation: uncomfortable and smelly.
Warm within the winter and cool in the summer, genuine Ugg Boots are made from Australian double-faced sheepsking, normally Australian Merino Sheepskin. The highest high quality around! Saving a couple of bucks will get you some synthetic fiber that’s not the exact same.
Some folks wonder if any animals are harmed during the making of Ugg Boots. The short answer is, the sheep is slaughtered. BUT, that sheep was going to be slaughtered for meat to feed people?ait is never really slaughtered to obtain the sheepskin. Sheep farmers acquire a secondary profit for selling the hides additionally to the meat. So, understand that the making of Ugg Boots doesn’t directly harm the sheep.
Sheepskins have to be preserved correctly before they may be processed into boots. Tanneries use big vessels called paddles, that hold anywhere from three,000 to 15,000 liters of salt water and slowly swish the skins around inside. This is a gentle process that takes about 10 days to get the hides properly tanned and ready to be cut for Ugg boots.
Step 1. Tanning/ Processing
The first step in tanning or processing of sheepskin is “Soaking,” which takes about 16 hours to complete. Throughout this method, the skins are thoroughly rinsed in cold water to remove any excess salt or dirt from the wool and pelt. This soaking method is carried out overnight in a vat of fresh cold water.
The next step within the tanning procedure is referred to as “Fleshing.” This part of the process uses a fleshing machine which removes any excess fat and muscle tissue from the underside of the sheepskins. This component of the procedure is crucial for allowing far more rapid and complete penetration of chemicals in the later stages of processing, especially throughout the pickling and tanning stages.
After Fleshing comes “Scouring.” This 30-45 minute segment of the procedure uses surfactants at high temperatures (around 38 degrees Celsius) and takes care of removing dirt and lanolin (grease) from the wool.
“Pickling” of the sheepskin then takes about 16 hours. Just before the sheepskin might be tanned, they have to be ) pickled. Pickling means soaking the skins in a solution of acid and salt. Adding salt prevents any possible swelling of the skins because of the acid. It’s necessary to lower the internal pH of the skins to somewhere between 2.8-3.0, which will permit the tanning agent to properly penetrate the skin.
The 16-hour “Tanning” step entails utilizing chromium salts which form cross-links with the collagen, thereby helping to stabilize the skin structure and preventing putrefaction or rotting. This step is performed at room temperature, around 25 degrees Celsius, and around a pH of 2.5-3.0. Once the tanning agent (the chromium) penetrates the skin, the process is stopped, along with the chrome is fixed to the collagen by raisng the pH to 3.6 making use of sodium bicarbonate and heating the skins to between 35-40 degrees Celsius. In performing so, the shrinkage temperature of the skin is raised to anywhere between 60-100 degrees Celsius.
Next comes “Wool Dyeing” or “Fatliquoring.” This takes anywhere from 3-4 hours to complete. After the skin is tanned, the wool may possibly be dyed any of many different colors. Wool dyeing needs to be performed at about pH 4.5-6 and at 60-65 degrees Celsius. Special “pelt reserve agents” must be added to maintain the wool dye from staining the pelt. Once the dye is stable, the pH is lowered to about 4.0 to fix the dyes to the wool, and fatliquor (emulsified oil) is added to the solution. Fatliquors are component of leather manufacturing that assist to lubricate the collagen fiber and permit them to move flexibly and freely once the skin is dried. This is what makes the leather really feel soft.
Drying of the skins then takes 4-24 hours. Forced air dryers are employed with the skins stretched across a frame. Drying occurs at 50-80 degrees Celsius.
Drycleaning must then take place over the following 4-24 hours. Either a white spirit (high boiling petroleum fraction) or perchloroehtylene is utilized to remove any natural fat or grease that remains within the skins.
Following final removal of the pelt grease, “Pelt Dyeing” or “Syntanning” comes next. Back within the paddle (the soaking vessel), the pelts are dyed in cooler temperature dyes (less than 30 degrees Celsius). This minimizes staining of the wool. After the pelt dyeing is completed, syntanning entails making use of synthetic tanning agents to make the pelts added fullness and firmness. Finally, the skins are dried once a lot more.
Step 2. Finishing
After the lengthy tanning procedure is complete, the final finishing is done so the skins could be utilized to make Ugg Boots.
The skins ought to be conditioned to approximately 20% moisture content. Staking is the procedure by which the skins are softened and stretched, and a “nappy” surface is added to the pelt.
Final “Combing,” “Ironing,” and “Clipping” then takes place to remove any tangles, burrs, or grass seeds that may possibly be remaining within the wool. The wool is straightened using an iron to remove the natural crimp. Lastly, a clipping machine creates an uniform wool pile at a desired length (typically 12-15 mm).
Step three. Manufacturing
A “clicking press” is used to cut individual panels from the skins. After being cut to the right size, the panels are then sewn together making use of unique industrial sewing machines. The soles are then glued to the boot upper, and, finally, the Ugg Boots are ready for you to buy.
