The method of genuine leather identification, genuine leather is made of animal skin, and many genuine leather on the market are fake. Many people often can't tell what genuine leather is when buying genuine leather, which often leads them to buy fake genuine leather products. Let's teach you the method of genuine leather identification.
Dermal identification method 1 1, vision
Look at these lines,
The lines of dermis are generally uneven, some places have larger lines, some places have smaller lines, and sometimes there will be small scars like human skin trauma, and sometimes there will be some uneven places. The grain of artificial leather is particularly regular and looks "perfect".
Overlooking the base,
The reverse side of the dermis has no foundation and looks a little fluffy. The reverse side of artificial leather has a cloth bottom.
Look at the pores,
Derma generally has tiny pores, which are not necessarily the same size. Artificial leather generally has no pores.
Look at this part,
The section of the dermis is composed of irregular fibers, and the upper and lower layers remain unchanged. Artificial leather can clearly see different materials like sandwich cake.
Second, the sense of touch.
Leather feels smooth in low temperature environment, and there is no cold feeling. Man-made materials are cold to the touch in a low temperature environment, and stiff to the touch.
It is better to pull the dermis to both sides by hand, but there are some differences in elasticity between transverse and longitudinal traction. Artificial leather has no elasticity when it is pulled by hand, or its elasticity is very small, so there is no difference between horizontal pulling and vertical pulling.
Third, the sense of smell.
Genuine leather smells like animal fat (that is, leather smells bad), while imitation leather smells like plastic.
Tear off a little fiber from the back of dermis and artificial leather, and it is artificial leather that emits a pungent smell and forms a knot after ignition; It's genuine leather that smells like hair without induration.
Other practical knitting methods.
1, comparing different leather pieces, a bag is rarely the whole leather, so you can look at different small leather pieces, it is impossible for each small leather to have the same texture, and each artificial leather has the same texture;
2. Find a place where you can see the leather section on the bag, and you can know whether it is true or not. If you can't find any section on a bag and don't give consumers a chance to verify their identity, you will feel a little insecure. Most of the materials used in this bag are not genuine leather.
3. Put tiny water droplets on the surface of its skin, and the water droplets immediately spread through pores, and you can see that obvious wet spots absorb water, which is dermis. If the water droplets are absorbed slowly, the dermis should be trimmed. /kloc-what is not absorbed within 0/0 minute should be double leather or artificial leather.
Method 2 of genuine leather identification How to distinguish genuine leather from imitation leather?
When identifying, we should first check the material and determine the type of upper leather. If the grain surface of "genuine leather" is used without modification, it has the original natural characteristics of upper leather:
Cowhide pores are small, irregular and uniform; The pores and eyes of goatskin are "tile-shaped" in rows; Pigskin has a pile of three holes and is distributed in a figure of eight. Cowhide has fine tissue fibers, rough buffalo hide and rough pores and eyes. If the modified particle surface layer loses its original characteristics, it should be carefully classified and identified according to the processing technology.
Aniline leather coated with aniline is characterized by crystal clear surface, bright light, no glare and no plastic feeling.
Natural leather is boiled into leather. Cowhide is generally 5 ~ 6 mm thick, with granular surface, fine and dense tissue fibers, smooth and beautiful, and good strength and wear resistance. The inner layer is a pile surface layer with thick fibers, large gaps and fluff on the surface. The surface of the first layer is smoother and smoother than that of the second layer, and the second layer is slightly rough. After coating, film transfer or film pasting, the surface of the two-layer leather may not be rough, but the film transfer leather has poor low temperature resistance and is easy to wrinkle at low temperature. The second layer of cowhide leather is smooth and has no obvious defects after embossing, while the second layer of pigskin leather often has three piles of pores faintly visible, where the luster is dark. It should be noted that the modified leather destroyed the original grain surface layer and then pressed the pattern. The pattern type can imitate cattle, sheep, pigskin and so on. However, the pattern has no pore eyes, and the pattern floats on the leather surface, while the pore eyes of the front leather exist, which can be identified by careful observation.
Artificial leather is coated with a layer of organic material on the basis of cloth, which can be divided into thin (imitation sheepskin) and thick (coated with foamed organic material and then pressed with patterns). Synthetic leather is made by pressing organic fibers and coating and laminating. Regenerated leather is made by grinding leather residue and leather fiber, bonding them with adhesive under high pressure to form thin slices, slicing them to the required thickness, and then finishing them to make them have certain leather characteristics. They are widely used in luggage and leather parts, and a small amount are used in shoemaking.
How to identify purses-To sum up, we can look at them from the following aspects:
1, look. Look at the appearance first, the leather has no base, and the artificial material has a base; Genuine leather has tiny pores, while imitation leather does not.
2. touch. If you touch it again, the artificial material has a strong plastic feeling and a bright luster, but it feels cold in winter, and the leather is smooth, so it doesn't feel cold.
3. Smell. Genuine leather smells like animal fat (that is, leather smells bad), while imitation leather smells like plastic.
4. News. Press the soft part of the finished product with your thumb, and many fine and even patterns will appear in the dermis around your thumb. When the thumb is raised, the pattern will disappear, which is the dermis. However, artificial materials do not necessarily have patterns, but may also have rough patterns. When the thumb is raised, the pattern does not disappear, indicating that the grain surface layer on the surface of the material has separated from the grid layer below.
5. check. Observing the cross section, the cross section of dermis is composed of irregular fibers. After scraping off the damaged skin fibers with nails, the cross section has no obvious change. For real leather, the texture of different parts is irregular, the nose smells fishy, while artificial leather smells plastic or rubber, and the texture rules of different parts are the same. Glued leather is a synthetic leather based on the inner layer of natural leather, which is not called "real leather", but an artificial surface layer attached to the loose fiber layer of the lower natural leather.
6. water. Put tiny water drops on the skin surface, and after a few minutes, the water drops will spread through the pores, and obvious wet spots can be seen to absorb water.
7. Burning. Burning the corners of the skin with fire smells like burning hair, and imitation skin smells like plastic.
8. color. Leather is dark, bright and soft, and imitation leather is bright.
Attached maintenance article: How to care and maintain genuine leather?
A, can't under strong light irradiation, in case of oil drying, leading to orange shrinkage of fiber tissue, leather hardening, brittle fracture.
B, can't put in strong acid, in order to prevent corrosion.
C, in the rain, put it in a ventilated place to dry, to prevent mildew.
D, when not used for a long time, put some paper inside to prevent deformation.
E. Real leather bags are delicate and easy to scratch.
F, after the leather bag is moldy, dry it with a soft cloth, and then apply Bellevue and other nursing agents.
G. When there are traces of ballpoint pens on it:
1. Remove with leather maintenance agent.
2, you can use milk for cleaning.
3. Wipe with a soft flannel dipped in a little oily cream, the skin will become soft and the scratches of the ballpoint pen will be removed.
4, you can use a clean flannel dipped in some egg whites to wipe, which can not only remove stains, but also make the leather surface as bright as ever (this trick can also be used in the maintenance of leather, general leather bags, such as last year's bags, may have mildew spots or dirty things on them this year, then you can use a flannel dipped in some egg whites to wipe, so that the leather bags can be restored as new!
Methods for identifying dermis Three commonly used methods for identifying dermis:
1, feeling
Touching the leather surface with your hands will make you feel smooth, soft, plump and elastic.
2. Eye view
There are obvious pores and patterns on the surface of dermis, while synthetic leather imitates pores, but it is not clear. In addition, the reverse side of synthetic leather has a layer of textile as the bottom plate to increase its tensile strength, while the reverse side of leather does not have this layer of textile. This identification is the simplest and most practical method.
Step 3 smell
Good quality leather generally has no peculiar smell, and all leather has the smell of leather. If there is a pungent smell, it may be that the tanning process is not handled well, and some chemical raw materials are used beyond the standard.
Step 4: ignite
The smell of the ignited dermis is similar to that of the ignited hair, and it does not knot in a knot after burning, so it can be ground with fingers; Artificial leather gives off a pungent smell when it is ignited, and forms a knot in one's heart after burning.
Common leather types:
1. Water dyed leather: refers to all kinds of soft leather made by bleaching and dyeing the top skins of cattle, sheep, pigs, horses, deer and other animals. Various colors, swelling and polishing.
2. Patent leather: leather made of two layers of leather blanks sprayed with various chemical raw materials by calendering or extinction.
3. Leather grinding: the leather surface is polished, and the grain surface scars or rough fibers are removed to expose neat and smooth leather fiber tissues, and then dyed into various popular colors to form the first layer or the first layer.
4. Suede leather: also called suede leather, it is the first layer of leather that polishes the surface of leather blank into suede and then dyes it into various popular colors.
5. Trimming dough: It is a kind of inferior first-layer leather blank. The surface is polished to remove the scars and traces of blood tendons on the surface, and then sprayed with various popular colors to make leather with grain or smooth effect.
6. Embossed leather: generally, various patterns or patterns are pressed with trimmed leather or open-edged beaded leather. Such as crocodile pattern, lizard pattern, ostrich pattern, python pattern, water ripple pattern, beauty pattern, litchi pattern, deer pattern, and various stripes, plaids, three-dimensional patterns or creative patterns that reflect various brand images.
7. Printed or burnt leather: The material selection is the same as that of embossed leather, but the processing technology is different. It is printed or burned.
