in this post I’m going to elaborate more on the process of how to tan the leather, if you are among those who constantly ask “what does tan mean”, keep reading this article. Have you ever been curious about the processes involved in creating the leather used in the goods you purchased? All leather goes through a multi-stage process that begins with drying and curing before moving on to tanning and coloring. We'll investigate the tanning process and figure out why the method used on the hide makes such a difference in the end product. Tannin is essential to the production of leather because, if it is not applied, the raw hide would deteriorate and become putrid. The tanning process preserves the integrity of the protein in the raw hide or skin by inhibiting the growth of putrefactive microorganisms and preparing the material for use in a broad range of final products. The primary distinction between dry skins that have been tanned and those that have not been tanned is that untanned hides will putrefy after they have been exposed to moisture, while tanned leather will not. The look of the hide also changes throughout the tanning process. The outcome is determined by the amount of time that passes as well as the tanning products that are used. The process of preparing animal skins for use in the manufacturing of goods such as belts, wallets, shoes, furniture, and clothes involves many steps. 
Before tanning, the hide or skin may go through processes like as fleshing, preserving or curing, bathing, liming, unhairing, splitting, deliming, bating, sanitizing, bleaching, pickling, and depickling. After the skins have been brought in from the farm or butcher, the following step is to clean them thoroughly and remove any remnants of meat that may be present. The next thing that has to be done is to salt cure the skins. Curing eliminates the risk of putrefaction by stopping the development of microorganisms on the hide between the stages of procurement and processing. It significantly lowers the amount of moisture that is contained in the hide. Wet-salting is one method for curing the skins; in this method, the hide is highly salted and then packed into packs for up to 30 days. This method may be used to cure the skins. One more method is to submerge them in a brine made of saltwater for around 16 hours. The process of tanning may be broken down into a few different steps, which are as follows: The first step is getting the hide ready to be tanned. The actual tanning process and any additional chemical treatments come in the second step. In the third step, which is known as retanning, retaining chemicals and dyes are applied to the material. This stage's purpose is to supply the material with the necessary level of physical strength and qualities depending on the finished product. 
In the fourth and last step, which is known as finishing, either finishing material is applied to the surface or the surface is finished without the use of any chemicals, depending on the preference of the individual. The first step in the preparation of hides is to salt the skins. Curing is used to check putrefaction of the protein material (collagen) since there is a possibility of bacterial infection owing to the time lag that may develop between acquiring it and processing it. This lag may arise because of the time it takes to procure it. It does this by extracting the surplus water from the hides and skins, which have a differential in osmotic pressure that causes water to flow from the inside. Because of this, the amount of moisture that is contained in hides and skins is drastically decreased. The process of wet-salting involves severely salting the hides, after which they are packed into packs for around one month. During the brine-curing process, the hides are agitated for about 16 hours in a bath of salt water. In general, the processes that are used to cure an item significantly reduce the likelihood that germs will be able to thrive on the item. The preservation of the hides and skins at a very low temperature is another method that contributes to the curing process. 
The hides are first salted, which is the first step in the preparation process. Curing is used to prevent the protein material (collagen) from going bad owing to putrefaction since there is a risk of bacterial infection as a result of the time lag that may develop between acquiring it and processing it. It takes the extra water out of the hides and skins, which is necessary due of the difference in osmotic pressure between the interior and outside of the animal. This results in a significant decrease in the amount of moisture that is contained in hides and skins. During the wet-salting process, the hides are first extensively salted, and then they are packed into packs for around thirty days. The process of brine-curing involves moving the hides around in a bath of salt water for around 16 hours. In general, the procedures that are used to cure food make it far less likely that germs will be able to thrive on the product. To this end, the hides and skins are stored at a very low temperature so that the curing process may continue. The hides are then submerged in clean water for a period of time in order to remove the salt and, more importantly, to restore the moisture content to an acceptable level before the hide or skin is subjected to chemical treatment in an aqueous medium. 
This procedure is referred to as "Soaking," and occasionally in addition to water, a very low amount of a hydrating agent is also used for the purpose of treating hides and skins that have grown very dry. To make a long story short, Tannin is very necessary for the production process of leather, as we have shown. Even though there are multiple steps involved, every one of them adds to the finish as well as the other properties that make leather so desired. As a result of the wide variety of tanning processes, which may vary from brain tanning to chrome tanning, the leathers that are produced will have a wide variety of pricing in addition to differences in color, thickness, and quality. It is my hope that you are now better educated to make a decision on the sort of tanning process used on the leather.
