1. Choose the right material 1. Touch, look, smell, burn, soak, five steps to recognize the dermis. "Leather" is a common word in the leather product market, and is a customary term for natural leather to distinguish synthetic leather. Hand touch: Touch the surface of the leather with your hands. If it feels smooth, soft, plump, and elastic, it is the real leather; while the surface of general artificial synthetic leather is astringent, rigid, and poor in softness. At first sight: the real leather surface has clearer pores and patterns, the yellow cowhide has relatively well-proportioned fine pores, the yak has thicker and sparse pores, and the goat skin has scaly pores. Smell: All leather has the smell of leather; and artificial leather has a strong irritating smell of plastic. Burning: Tear off a little fiber from the back of real leather and artificial leather. After lighting, the leather that smells of hair and does not form lumps is the leather.

It is artificial leather that emits a pungent odor and lumps; water absorption: the surface of the dermis has better water absorption, while fake leather has better water resistance on the contrary. You can dip your finger in some water and wipe it on the surface of the clothing to observe its water absorption. For example, the water absorption is good, it is leather, and the water absorption is poor or not at all, most of which are fake leather. 2. How to distinguish cowhide, pigskin, horseskin and sheepskin pigskin: The pores on the surface of the leather are round and thick, and the pores are inclined to extend into the leather. The pores are arranged in groups of three, and the leather surface presents many small triangle patterns. Cowhide: Both scalper leather and buffalo leather are called cow leather, but there are certain differences between the two. The pores on the surface of the scalpel leather are round and extend straight into the leather. The pores are tight and even, arranged irregularly, like a sky full of stars. The pores on the surface of buffalo leather are larger than that of yellow cattle leather, and the number of pores is less than that of yellow cattle leather. The leather texture is looser, not as fine and plump as yellow leather. Horse skin: The hair on the leather surface is also oval, slightly larger than the scalper leather pores, and the arrangement is more regular. Sheepskin: The pores on the grain of the leather are oblate, with clear pores. Several pieces form a group, arranged like fish scales. Different types of leather have different characteristics and uses. For example, cow leather has fine surface and high strength, which is most suitable for making leather shoes; sheep leather is light, thin and soft, which is an ideal fabric for leather clothing; pig leather has good air permeability and water vapor permeability.

2. See clearly the workmanship: flat, smooth, no seams outside of the design, no bubbling, no exposed burrs. Xiquan is made of first-layer cowhide and feels comfortable. The quality can be guaranteed by the manufacturer's brand authorization. Inside the bag: Whether you choose textiles or leather products, the color should be coordinated with the surface of the bag. The lining has more seams, and the stitches should be fine and not too large. The perfect and fine car line craftsmanship is perfectly presented in the leather bags of the Xijiajia marketing center. Wrap tape: is the most vulnerable part. Check the straps for seamless fit and cracks, and see if the connection between the straps and the body is strong. All kinds of bags should pay attention to the straps, and backpackers will pay more attention to the load-bearing and firmness of the straps, so pay special attention to them when choosing.
