At present, the popular leather products on the market are divided into two categories: genuine leather and artificial leather. Synthetic leather and artificial leather are made of woven fabric or non-woven fabric base, respectively coated with polyurethane and special foaming treatment. The surface feels exactly like real leather, but the air permeability, wear resistance and cold resistance are not as good as real leather. How to distinguish genuine and fake leather products?

1. Leather surface: The natural leather surface has its own special natural pattern, and the leather surface has natural luster. When pressing or pinching the leather surface by hand, the leather surface has no dead wrinkles or creases, nor cracks; while the leather surface of artificial leather is very similar Natural leather, but the pattern is unnatural, the luster is brighter than natural leather, and the color is mostly bright.

2. Leather body: natural leather, soft to the touch and tough, while imitation leather products are also very soft, but the toughness is insufficient, and the leather body becomes hard when the climate is cold. When the leather body is twisted by hand, natural leather bends back naturally and has better elasticity, while the bending motion of imitation leather products is stiff and poor elasticity.

3. Incision: The color of the incision of natural leather is uniform, and the fibers are clearly visible and dense. The incision of the imitation leather product has no natural leather fiber feel, or the fiber and resin at the bottom can be seen, or the base fabric and resin can be seen from the incision in two layers.

4. Inside the leather: The front of natural leather is smooth and flat with pores and patterns. There are obvious fiber bundles on the reverse side of the leather, which is hairy and uniform. In the imitation leather products, the front and back sides of some synthetic leathers are the same, with good gloss on the inside and outside, and also very smooth; some artificial leathers are different on the front and back, and obvious base cloth can be seen in the leather; but some leather linings are imitated. Like natural leather, the leather also has fluff like natural leather. This requires careful observation of the difference between true and false varieties.

The raw material for tanning is animal skins. Although pigskin, cowhide and sheepskin are the most common in our lives, in fact most animal skins can be used for tanning. However, cowhide, pigskin and sheepskin are of good quality and large in output, and they are the main raw materials for leather making.
Although there are many types of raw leather for tanning, according to a series of laws and regulations such as the animal protection regulations issued by the international, the raw materials used for production are restricted to a certain extent. The commonly used leathers are: cow leather, sheep leather, pig leather and horse leather. leather.
