The tanning process
Leather making is not an easy process as people say or think. It is quite a complicated process. The easiest method to understand the process of tanning is to understand leather preparation. The easiest way is that you can understand how the layers of the leather are separated. leather making workshop could be learned in order to understand the process. And how these split layers produce a high-quality piece of leather. And also, how the leather is split across according to its thickness to make up the topmost layer and also the under layer. The top layer of the leather is known as the full-grain and it describes the side that is exposed to the elements that give the correct amount of durability and also the mallenity it needs in order to be considered as a leather. The underside of the leather is stiff and also it is less durable when compared to the top layer. This is a practical use for creating and for the treatment after the coating is applied. The process that is required for tanning takes place in 5 distinct steps respectively known as Pre-Tanning, Tanning, Selecting, Dressing, and Finishing. Every one of the processes in the different stages requires work and it is complicated. The following is nothing but a brief outline of the important steps in the 5 stages of the process of making leather.
STEP 1: PRE-TANNING
Soaking – the leather will arrive at the tannery in the form of a hide. So first it requires curing to remove all the unwanted and all. And after that, it needs to be soaked in water therefore it will extrude salts used in preserving leather. This process is done with the help of revolving drums that is capable of holding up to 200 hides.
Liming – This process is followed after the process of soaking. The hair and the epidermis need to be removed before continuing with the other stages of tanning. Therefore, in the lying process, a solution of line and sulfide is mixed and applied to the hide in order to remove the unwanted hair from the hide. This will also be known to increase the softness of the leather and also gives much flexibility that is needed in order to uphold the leather. The next process in the pre-tanning stage is called Splitting. Splitting is a stage where the hide is split into layers. The topmost layer which is also known as the grain, the layer will produce a fine, smooth grain leather. The bottom layer is used for suede or splits leather for other uses.
STEP 2: TANNING
This is the process that converts pre-tanned hide into leather. Tye tanning that is used with the help of the minerals is usually done with alkaline chrome-3 salts. It gets into the hide fairly quickly within 24 to 48 hours. This will then result in a pale duck-egg blue, which will yield a soften and good finish after the processing. It will give out a modern finish. When you are not able to do tanning with the help of the sodium then it is good to do tanning with the help of the vegetable and the combination of the syntan and polymers. This will be a good alternative.
