First, how to identify the leather
Hand touch: When you touch the leather surface with your hands, the feeling of smoothness, softness, plumpness, and elasticity is the dermis; and the surface of the artificial synthetic leather is astringent, rigid, and soft.
Seeing: leather dermis has clearer pores and patterns, yellow leather has more uniform fine pores, yak skin has thicker and sparse pores, and goat skin has scaly pores.
Smell: All leather has an odor of leather; artificial leather has a strong irritating plastic smell.
Ignite: Tearing a little fiber from the back, igniting hair, emitting a scent of hair, leaving the hard cheeks in the dermis; emitting a pungent odor and forming a leatherette.
Second, how to identify artificial leather and synthetic leather.
Artificial leather and synthetic leather are made of textile cloth or non-woven leather, coated with polyurethane and treated with special foaming. The surface feels like leather, but breathability, abrasion resistance and cold resistance are not as good as leather. . How is it different?
Leather surface: The leather surface of leather has its own special natural pattern. The surface of the leather is shiny and natural. When the leather surface is pressed or pinched by hand, the leather surface is free of wrinkles or dead folds, and there are no cracks. The leather surface of artificial leather is like leather. But looking at the pattern is not natural, the gloss is brighter than the leather, and the colors are mostly bright. Pressing the leather surface with your fingers does not have obvious pore wrinkles. Even if there are wrinkles after pressing, it will not disappear naturally.
Leather body: The leather feels soft and resilient, while the leather-like products are soft, but they have insufficient toughness and they harden when the climate is cold. When the leather body is twisted by hand, the back of the leather is natural and the elasticity is good, while the leather goods are hard and elastic.
Incision: The dermis has a uniform color at the incision and the fibers are clearly visible and fine. However, the cuts of imitation leather products do not have a fibrous sensation of the dermis, or the fibers and resin at the bottom are visible, or the bottom cloth and the resin are glued at two levels from the incision.
Leather: The front of the dermis is smooth and smooth with pores and patterns. On the reverse side, there are obvious fiber bundles that are woolly and uniform. Imitation leather products have no pores on the surface, some synthetic leathers have the same front and back, and the outside gloss is good and smooth. Some artificial leathers are not the same on the positive and negative sides. The leather can see obvious bottom fabrics; but there are also others Like the dermis, there are also velvet like leather, which requires careful observation of the differences between genuine and fake leather.
Third, how to identify cowhide

The texture is full and delicate, and the appearance is smooth and soft. The texture of the hand is firm and flexible. If you squeeze the leather hard, small folds appear.
Yellow leather hole is small, round, even and tightly distributed, the pores extend straighter to the inside, irregularly arranged, as if starry. The leather surface is full, bright, and the skin is soft, grainy, strong, and elastic.
Buffalo leather: The pores are thicker and less dense than the yellow leather, and the cortex is more slack. It is generally used as a sole.
Fourth, how to identify sheepskin
Sheepskins are characterized by a grainy, flat, pored, darker skin inside; the pores are clear, and several roots are arranged in a row, arranged like a scale or jagged. Pattern features such as "water ripples". Sheepskin is light, thin and soft. It is the ideal fabric for leather garments. The finished garments are beautiful in appearance, soft and natural in luster, light and soft, and flexible, as long as the strength is not as good as leather and pigskin.
Sheep skin: There are more fats in the cortex. The fibrous tissue of the skin is loose. It is very soft. The grain is fine and smooth. The extensibility is large, but it is not strong.
Goatskin: In the cortex, there is less fat. The fibrous tissue is fuller than sheep skin. The pores are clear, and the cortex is elastic. It is solid and durable.
Fifth, identify other leather
Pork skin: The pores on the surface are round and thick, and extend obliquely into the leather. The pores are arranged in three groups and the leather surface is in the form of many small triangles. The leather surface is uneven, rough, and poor in softness. Generally, it is used after being repaired.
Horse skin: oval pores, not obvious, slightly larger than the cowhide hole, oblique into the skin was a mountain shape, regular arrangement, leather is loose, dark and shiny, bright as leather. Squeeze the skin with force and no wrinkles are produced.
