(1) Leather goods are mainly genuine leather made of animal skins. Mainly pigskin, cowhide, sheepskin, horse skin and so on. Cowhide is divided into cowhide and buffalo hide;

(2) According to its levels, it can be divided into top skin, second skin and third skin. Precious are: fox skin, goat skin, rabbit skin, mink, etc ... They are expensive and feel first-class, so I won't list them here. ?

2. Eye view

A, the surface of the dermis has irregular particles with uneven shape, and each particle surface has a very fine breathing hole, which is very clear. The breathing holes in the skin of different animals are different. For example, the pores of cowhide are relatively uniform, and the consumption of cattle is relatively thick. Goatskin pores are like fish scales, and pigskin is triangular.

Safe.

B, if you can see the best section of the skin, generally one side is smooth and the other side is fluffy.

touch

When you directly touch leather products with your hands, you will feel the feel of leather. Generally, there are particles of different sizes on the surface of leather goods. If you press it by hand, it will be elastic. If you pull leather by hand, you will feel the toughness and smoothness of leather. Generally, inferior leather or inferior leather and artificial leather have shown differences in this feeling.

Step 4 smell

A, whether it is genuine leather, fake leather or even artificial leather, it has its own smell.

B, leather has the smell of leather itself, with a touch of animal smell. Artificial leather, or artificial leather, does not have this taste, especially artificial leather, which tastes very exciting, like plastic, not very good, not very good for human body.

C, because the price is cheap, so many "black-hearted" manufacturers will use the smell of spraying some leather to go in for opportunism, so be careful.

5. Burning

First, the leather scraps burn and have a chemical reaction, which is immediately true and false. True gold is not afraid of fire, it is true. The smell of burnt leather is the same as that of burnt human hair. If you can't remember the taste, you can perm your hair first. As a result of combustion, the combustion products do not agglomerate, but become powder by hand. Moreover, leather has better flammability and longer burning time than leather.

B, artificial leather, other fake leather, has a strong chemical glue smell when burning, and the products are less papules, which are not easy to powder.

From here, we can basically know who is true and who is false.

6, leather logo

First, the industry has clear standards. As long as it is a regular manufacturer registered by the Industrial and Commercial Bureau, there will be a certification trademark issued by the Industrial and Commercial Bureau.

B. The registered trademark of the genuine leather logo is an artistic deformation pattern consisting of a whole sheep, a diagonal and a leather shape. The overall pattern is a circular drum with three letters GLP in the center, which is the English abbreviation of genuine leather products. The main color of the pattern is black characters on a white background, and only three letters are red. Moral of the pattern: Cattle, sheep and pigs are the three main natural leather raw materials for leather products. The pattern is round and drum-shaped, which symbolizes the drum of the main processing equipment in leather industry on the one hand, and the rolling development of leather industry on the other hand.
