In terms of leather goods, we can start with our leather materials. Even for genuine leather, there are great differences in materials and specifications. It is necessary to prevent it from being used by merchants and used as a cover to buy leather clothes with relatively low cost performance. The raw leather stripped from horses, sheep, pigs, cattle or other animals is made of leather materials with various hand feel, patterns and colors after being processed by the leather tanning factory. In this process, pig skin, sheep skin and cow leather are the three major varieties of all raw materials.
At present, the first layer of cow leather is mainly divided into three kinds: buffalo leather, yellow leather and calf leather. In terms of yellow leather, the grain surface is more detailed, the strength is higher, the cortex is thicker, and the elasticity and fullness are better. The main feature is beautiful finished products, and they are more durable and comfortable. On the rough surface of buffalo hide, it has coarse and loose fiber and strength, which is lower than that of cattle hide, and there is a greater difference in performance compared with cattle hide. Another is the best of leather products: calf leather. The real calf leather uses the calf of yellow cattle as the carrier, which mainly has many advantages of the cow leather, and also improves the disadvantage that the softness of the cow leather is not high enough, and the quantity will be less. Therefore, it can be seen that under the general cow pen, it belongs to selling meat, and only a small part of the income in terms of the skin. Meat is the big part of our income. Killing the calf requires the income of skin, And the price of this kind of leather is very high.
The main component contained in the raw materials of leather goods is protein, so it is very easy to be affected with moisture, insects and mildew. In the process of use, we should avoid contact with acidic, alkaline, oil and other substances. In the maintenance of leather goods, we should use professional technology or professional equipment for cleaning, and then add a special agent for sterilization and mildew removal, which can completely remove all kinds of molds and bacteria, and then fundamentally avoid a kind of mildew phenomenon. After comprehensive cleaning, it can be well preserved and properly handled, which plays a very important role in maintaining the original appearance and prolonging the service life.
