The difference between recycled leather and real leather and artificial leather

First, the dermal fiber, cross-linked fiber, resin and other additives are mixed. The process is as follows: the raw materials of leather or recycled leather are crushed into a certain size of leather fiber, and then it is mixed with natural rubber, resin and other raw materials, and then compressed into a filter cake; The filter cake is heated so that the fiber on its surface is melted and sticky. The final product is obtained after each layer is extruded, bonded, dehydrated, cooled and dried, sliced, embossed and treated. Main features: Recycled leather has the characteristics of real leather and PU, and is a very common leather fabric today. Like real leather, recycled leather has moisture absorption, air permeability, good workmanship also has the same softness and elasticity as real leather, light texture, extreme high and low temperature resistance, wear resistance. The disadvantage is that the strength is worse than the leather of the same thickness, of course, it is also worse than PU, and it is not suitable for leather goods with large forces such as shoe upper. Because the production process of recycled leather is more flexible and can be adjusted in real time, by increasing the amount of natural latex and changing the process formula, you can also make a variety of products with different hardness and strength to make up for her own shortcomings. Its late surface treatment is similar to PU, in the surface texture and color of recycled leather is not only refurbished, new products emerge endlessly through. More important is her very competitive price, only one tenth of the leather, three times the PU, very good value, cost-effective.

Types and identification of leather

Leather is divided into natural leather (leather), recycled leather, artificial leather (PU/PVC). Leather is the raw skin of cattle, sheep, pigs, horses, deer or some other animals, after tannery processing, made into a variety of characteristics, strength, feel, color, pattern leather materials, is the essential material of modern leather products. The dermis is generally composed of the epidermis (removed), dermis, reticular layer, subcutaneous layer (removed), etc. Among them, cowhide, sheepskin and pig skin are the three major kinds of raw materials used for leather.
