Classification method of recycled leather
Recycled leather technology: First, the leather fiber, crosslinked fiber, resin and other additives are mixed. The process is as follows: pulverize the raw material of leather or recycled leather into a certain size of leather fiber, then mix it with natural rubber, resin and other raw materials, and then compress it into a filter cake; heat the filter cake to make its surface layer The fibers are melted and sticky, and the layers are extruded, bonded, dehydrated, and dried, sliced, embossed, and surface treated to obtain the product. Main features: Recycled leather has the characteristics of both genuine leather and PU, which is a very versatile leather fabric today. Like genuine leather, reclaimed leather is hygroscopic and breathable, and it has the same softness and elasticity as genuine leather, light texture, strong resistance to extreme high and low temperatures, and abrasion resistance. The disadvantage is that the strength is worse than leather of the same thickness, and of course it is worse than PU, which is not suitable for leather goods with higher stress such as uppers. 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, it can also make a variety of products with different soft hardness and different strength to make up for her own shortcomings. The later surface treatment is similar to PU, and the recycled leather is also decorated in surface texture and color. What's more important is her extremely competitive price, which is only one-tenth of that of genuine leather and three times that of PU, which is very good value and cost-effective.
Types and identification of leather Leather is divided into natural leather (genuine leather), recycled leather, and artificial leather (PU / PVC). Genuine leather is the raw skin peeled from cattle, sheep, pigs, horses, deer or some other animals. After processing by the leather factory, it is made into leather materials with various characteristics, strength, feel, color and patterns. It is a modern leather product. Required materials. The dermis is generally composed of an epidermal layer (removed), a dermal layer, a reticular layer, and a subdermal layer (removed). Among them, cowhide, sheepskin, and pigskin are the three major types of leather used for tanning.
