Teach you how to identify the brand -name bags of different leather? When you buy bags, you usually like to choose a bag of leather materials. One is that the leather bag can be more grade, and on the other handdurable.At present, there are three types of cortex on the market mainly three types: leather, regenerative leather, and PU artificial revolution. Today, I will introduce the characteristics of these three cortex materials to help everyone find one of them when choosing a famous package.
The leather is generally the original skin of cattle, sheep, pigs, and animals, which are made into various leather materials.The leather is divided into two types: head layer skin and two -layer skin.The head layer is directly processed by the raw skin such as beef, sheep, and pig skin with grain noodles.What kind of animal leather can be distinguished from the thickness and density of pores.The second layer of leather is a loose two -layer part of the fibrous tissue in the raw leather.
The distinction between the head layer and the second layer of skin is to observe the vertical cut surface fiber density of the skin.The head layer is composed of a dense and thin fiber layer and a slightly loose excessive layer that is closely connected with it; the second layer of skin is only a loose fiber tissue layer, spraying chemical raw materials or polishing, etc.The more popular leather afterwards.
The regenerative leather is made by crushing the waste skin and dermis of the animal, and the chemical raw materials are prepared.It is characterized by its neat edges, high utilization, and cheap prices; but the skin body is generally thicker and poor.This is the main material for small product factories to make flower leather shoes.
The imitation leather or rubber is the general term for artificial materials such as PVC and PU.It is made from the spin -based or non -woven base, which is processed or covered with foam or coverage of various formulas of PVC and PU. It is characterized by: there are many varieties, good waterproof performance, neat edges, high utilization rates and high utilization rates and high utilization rates and high utilization rates and high utilization rates and high utilization rates and high utilization rates and high utilization rates and high utilization rates and high utilization rates and high utilization rates and high utilization rates and high utilization rates and high utilization rates and high utilization rates and high utilization rates and high utilization rates and high utilization rates and high utilization rates.The price is relatively cheap.
Advanced PU, the fibrous tissue of the extremely basic material of the surface process, almost achieves the effect of the leather, and its price is comparable to the price of domestic head layer leather.There are many people who advocate environmental protection abroad who like to choose a high -grade PU material.
