2 second layer leather
The second layer of leather is obtained by splitting the skin with a sheet of leather. The top layer is used for full grain leather or shaving leather, and the second layer is made of two layers of leather after finishing or filming.
The second layer of leather still retains the characteristics of the skin, but its fastness is not as good as the top layer.

The leather can be divided into animal species or by tanning.
Xiaobian here recommends some hand-made leather common leathers according to the tanning method.
Tanning is an important process in tanning, and the process of turning the tanning into a leather by tanning is called tanning. It is a process in which the skin is combined with an expectorant to make the hide become a non-perishable leather. The main tanning processes are: vegetable tannins, chrome tanning, oil tanning and so on.
1 vegetable tanned leather
Plant tanned leather is a leather made from plant tanning agents. Plant enamel is a polyphenol compound which can be used to convert hides into leather, such as tannins and plant polyphenols contained in plants.
The production of vegetable tanned leather, starting from the original fur, takes more than three months to make. It is a simple, natural and environmentally-friendly leather that smells a sultry aroma. The primary color is similar to the human skin. It can be dyed and dyed in various colors.
The most fascinating thing about it is that as the sun is exposed during use, body temperature and the oil secreted by the human body moisturize, the color of the leather surface will gradually deepen, and the skin color gradually turns into a tan or reddish brown, just like a wenwan. The palating process produces extremely rich texture changes, commonly known as “raising cattle” and “cultivating skin”.
