Manufacturing technology of leather

Compared with PVC leather, the manufacturing process of PU leather will be more complex, and the Pu base cloth will be PU material with relatively good tensile strength. In addition to the top of the coated base cloth, the base cloth can be included in the middle, and its main base cloth will not be seen in appearance. The performance of PU leather is relatively better than that of PVC leather in terms of physical properties, and it is more resistant to twists and turns, has better softness, greater tensile strength and better air permeability. In the production of PU coated fabrics, clothes will give people a unique feeling in summer, as if the fabrics are about to melt away.
In fact, for high-quality microfiber leather, it has surpassed many middle and low-end dermis in terms of life and strength, and is also very close to dermis in terms of appearance, color and hand feel. It can only catch up with leather in terms of moisture absorption, air permeability, elasticity and cold resistance. In this regard, when pursuing durable leather goods and super fiber leather, the price should be only about one-third of that of genuine leather. Therefore, leather is better than imitation leather, and there are only some aspects that are better. In most families, the reason why people buy genuine leather is mainly due to the desire for durability. From a professional point of view, the purpose of purchasing genuine leather should be the comfort and artistic feeling of genuine leather.

In terms of comfort, leather is a kind of natural protein animal fiber. It feels more delicate and can exist in the form of sitting and lying on the leather. It is very soft and elastic. It is often referred to as “flesh feeling”. At the same time, it can make it feel close to and breathable on its pores, which is a function that imitation leather does not have. In addition, in terms of our technology, because the leather has relatively good elasticity and can be used to contain leather products, it will appear very natural and more curved at some corners. Second, the texture of leather is relatively natural, but unlike the texture of imitation leather, it belongs to artificial repetition. People engaged in design or art will clearly understand that there is no sense of beauty.
The so-called artificial leather is not leather, but synthetic materials derived from petroleum and other minerals. Imitation leather seats commonly used in cars are essentially artificial leather.
Commonly used artificial leather mainly includes PVC (polyvinyl chloride), PU (polyurethane) and other types. Among them, PVC is a kind of imitation leather material with low price, the most widely used and the most common. Pu material is of better quality, close to leather, and the price is higher.
