First of all, by observing the appearance of the leather, the color of the general leather chair is bright and soft, and there is no reflection;
Followed by touching it, feeling its texture, good leather chair surface surface The feel is very good and has a toughness, while the secondary one is smooth, but the feel is hard;
Finally smells its taste, the leather generally does not have a pungent taste, and the false one is generally band Solvent and paint flavor.
The finished product of the leather is the skin (that is, the epidermis of the animal body), and the artificial simulation, super fiber skin, and synthetic leather are volumes and volumes.
Looking at the back
The focus of falsification is on the surface of the skin. Then, let's copy it to the back to distinguish the authenticity. There will be a natural short fiber behind the leather, which will not drop with nails. The back of the fake skin is generally smooth cloth, without hairy fiber. There is a super fiber skin, and there will be fiber on the back, which is also a fake skin. The following method is used.
The smell of smell
We have to believe in our natural weapons-nose. The leather has a natural taste. This taste comes from the fur itself, which is difficult to remove clean.
Because the fake skin is synthesized by chemicals, under the careful smell, there will be a smell of plastic of chemical industry, which makes people reject.
The pattern on the leather surface is processed acquired. No matter what patterns, there is one thing, the stretching of the lines on the overall plane will be intermittent, and there is no regular pattern. The plane of the fake skin is very regular.
Some small shops and small shops in the leather industry often use film skin to charge. Behind it has fibrous fibers and skin flavors, and it is difficult to distinguish on the lines. Then use another move to deal with it, find a margin to use nails to pick the surface spray coating, the epidermis will be lifted like a solidified glue, because it is a imitation, coating, and it made of slurry after powdering. Instead of adhesion. Pulling the side hard, the leather is also easy to crack.
Hand -touch: that is, touch the surface of the leather with your hands. Essence
Seeing: The leather surface has clearer hairs and patterns. The orange leather has relatively well -proportioned fine pores. The yak leather has thick and sparse pores, and sheep skin has fish -scale pores.
Sniff taste: Every leather has the smell of leather; and the artificial leather has a more irritating plastic smell.
Litting: Tear a little fiber from the back of the leather and artificial leather. After lit, the pungent smell is made, and the artificial leather that forms a pimple; the skin that is made of hair, and it is the leather that does not knot hard bumps.
