The leather products popular in the market are leather and artificial leather. Synthetic leather and artificial leather are made of woven fabric base or non-woven base, which are respectively coated with polyurethane and specially foamed. The surface feels like leather, but the breathability, abrasion resistance and cold resistance are not as good as the leather. How to distinguish between genuine and fake leather products?
1. Leather surface: The natural leather surface has its own special natural pattern. The leather surface is natural and lustrous. When pressing or kneading the leather surface, there is no dead or dead pleats on the leather surface, and there is no crack. The leather surface of the artificial leather is very similar. Natural leather, but look carefully at the pattern is not natural, the gloss is brighter than the natural leather, the color is mostly bright.
2. Leather: Natural leather, soft and tough, but imitation leather products are also very soft, but the toughness is not enough, the leather body is hard when the weather is cold. When the leather is twisted by hand, the natural leather is natural and has good elasticity, while the imitation leather product is hard and has poor elasticity.
3. Incision: The color of the incision of the natural leather is the same, and the fiber is clearly visible and fine. The cut of the imitation leather product has no natural leather fiber feel, or the fiber and resin at the bottom are visible, or the base fabric and the resin are glued to two levels from the slit.
4. Inside the leather: The front of the natural leather is smooth and flat with pores and patterns. The reverse side of the leather has a distinct fiber bundle that is fluffy and uniform. In the imitation leather products, some synthetic leathers have the same front and back sides, and the outer and outer lusters are good and smooth. Some artificial leathers have different front and back sides. The leather can see obvious base fabrics; but some leather leather surfaces are similar. Like natural leather, there is also a fluff like natural leather in the leather. It is necessary to carefully observe the difference between true and false varieties.
Sheep leather: It is characterized by a flattened pore of the grain surface, which is obliquely deep into the leather. The pores are arranged in a group, which is arranged like a scale or a zigzag. The pattern features such as "water ripple". In sheep leather, it is divided into sheep leather and goat leather.
Sheep leather: The skin has more fat content, the fiber structure of the leather is slack, it is very soft, the grain surface is fine, and the elongation is large, but it is not strong.
Goat leather: The skin has less fat content, and the fibrous tissue is fuller and more durable than sheep leather.
The difference between the two: the grain of the sheep leather is fine and smooth; the goat's leather has clear pores and the leather is elastic. No matter which kind of clothing made of sheep leather products has beautiful patterns, the gloss is soft and natural, light and soft, elastic, but not as strong as cow leather and pig leather.
The epidermis is located under the hair and adheres to the top of the dermis and is composed of different shapes of epidermal cells. The thickness of the epidermis varies from animal to animal, for example, the thickness of the skin of the cowhide is 0.5 to 1.5% of the total thickness; the thickness of the sheep skin and the goat skin is 2 to 3%; and that of the pig skin is 2 to 5%. The dermis is located beneath the epidermis, between the epidermis and the subcutaneous tissue, and is the main part of the hide. Its weight or thickness accounts for more than 90% of the hide.
The raw material for tanning is animal skin. Although the most common in our life is pig skin, cowhide and sheep skin, in fact most animal skins can be used for tanning. Only cowhide, pigskin and sheepskin are of good quality and high yield, which is the main raw material for tanning.
Although there are many kinds of raw materials for tanning, according to a series of laws and regulations such as the international animal protection regulations, the raw materials used for production are limited to a certain extent. The commonly used leathers are: cow leather, sheep leather, pig leather and horse. leather.
