The leather making process involves a complex set of measures for the skin to the finished product. These steps are often called "tanning" because the process more typical, with tannic acid present in the plant matter to chemically modify the skin does not decompose or rot.
When used without any treatment, the skins of animals quickly break down and starts to stink. For this reason, the skin should be treated to form the skin. The process can be decomposed into two

The skin has three layers beginning with the skin, the dermis, and ending in adipose, also known as meat. When leather, only the skin firm and supple, a layer of collagen fibers, is preferred. Collagen is secreted by cells and form a network of utility lines. When it comes to skin, these fibers are retained the rest is torn.
First, the skin is the meat, to be cleansed from the skin and fat or fat of animals off the excess. Then the skins are washed and soaked, to rehydrate dry skin, while the loosening of the blood and dirt. The chemicals are added in turn, alkaline water, to gnaw hair and skin. The collagen fibers begin to swell, while excess of precipitated protein.
Upon completion of this process, water is carried a stable pH and reduces inflammation, so that enzymatic cleaners can be added to remove remaining organic waste. Then the skin is immersed in a highly acidic solution, preparing for your tan. Tanning agents form bonds with collagen in the skin, cause to resist the attacks of bacteria, and the skins are removed treatment tank wet blue finish, after have been carried out through rollers to remove excess water.

Then the leather is dried, treated mechanically soften and replenish what has a soft and attractive. Some skins are marked with patterns before the final stage, which is the function of a finishing layer of polymer or wax to protect the leather surface.
