In terms of raw cowhide, we need complex treatment in three main stages and dozens of processes, which can become the leather we see now. At present, these three stages mainly include our preparation, tanning and finishing stages. At the beginning, the preparation stage belongs to the preliminary processing stage. The main purpose is to remove some useless things in animal skin, such as fat, hair, soluble protein, etc. the fibrous collagen of animal skin can be treated as the main body of leather, so that it can be used for later processing and improve the quality of leather. In terms of process, it mainly has the effects of soaking, cleaning, liming, degreasing, depilation, pickling, softening and so on.
The tanning stage is a key stage for the denaturation of our leather. Our chemical method is used to change the structure of animal skin fiber collagen and turn the skin into leather. At the same time, it also directly determines the performance and quality of the leather. Tanning mainly includes chrome tanning, vegetable tanning and so on. Tannic acid solution of natural vegetable tanning agent will be used in vegetable tanning, which is very natural and environment-friendly and does not contain harmful substances. The cortex is also very flexible and relatively single in color. For chrome tanning, the heavy metal chromate used can be used as its tanning agent, and the cortex is relatively soft and has rich colors, which is relatively poor in environmental protection. In terms of process, there are primary tanning, retanning, grading and so on.
The finishing stage is mainly after tanning and finishing before it can be used as leather. After finishing, the leather surface can form the appearance of many colors, styles and luster, and the leather can obtain certain maintainability and waterproof. In terms of process, it mainly includes engineering processes such as chipping, slicing, dyeing, neutralization, fatliquoring and so on.
Leather has always been a very personalized choice for us. Compared with those who have been pursuing pure originality, it is undoubtedly a perfect material. And although any leather product has its own way and aging, we can have many ways to make our shoes, suitcases and jackets look like our favorite from the beginning. In terms of jacket customization, mobile phone cases printed with acronyms, and our hand-made board games, we have helped you find the right leather items.
In the leather products industry, leather is the most common word, and it is also a customary name used to distinguish synthetic leather and then leather. Leather has a wide variety and many differences in quality, so there will be a great difference in price. First, we need to know what leather is. Because the leather is mainly a kind of leather that can be directly peeled by animals and turn the original raw leather into a kind of leather that can withstand high temperature and dry and wet wipe after leg hair, soaking, acid invasion and tanning process. After finishing the leather and springboard, it will make us softer in the future. For the smooth leather in leather, many leather products are often used. Because the tensile strength of the smooth leather is relatively good, and it is wear-resistant and dirt resistant, it has very good air permeability. Suede leather is more generous and elegant in appearance and better in air permeability. The disadvantage is that it is very easy to get dirty and is not well maintained. Especially in a bad environment, suede leather shoes are very easy to inhale dust and fall down after encountering water-
