High quality natural leather is soft, plump, crisp, breathable, solid, tensile, folding, tear strength and other properties are up to standard, as long as proper maintenance, "aging" is very slow.

In the following aspects: color fastness, coating adhesion, materials, leather strength, processing and so on.

Consumers should pay attention to the following points when buying leather goods: we must recognize the trademarks, specifications, name and site of the leather garments, do not buy products without registered trademarks, and do not indicate the products of the manufacturers; two, leather clothing should not be such as fading, cracking, slurping, etc. The hand feeling should be plump and elastic. The color of the whole dress is uniform, no color difference, color flowers, smooth leather and fine grain. Three is a "touch", two "smell" and three "look".

"Touch" should be soft, plump and elastic. "Smell" should have no strong odor. It should be tasteless.

Generally three or four pigs or five or six sheep can make a fur coat, so the overall effect of leather clothing should be thin, thick and thin, and the color match properly. The smaller the primary and secondary parts, the better.

Plump and loose noodles are leather quality.

Sensory examination

The main points.

Leather is full of handle. It is that the skin fibers are dispersed moderately during processing, and no loss has been suffered, so that the skin fibers still maintain certain spatial configuration and good elasticity.

Loose surface refers to the loose grain and loose density of leather. When testing, the leather can be bent 90 degrees inside the surface, and larger wrinkles appear on the grain surface. When the surface is flat, wrinkles can not disappear completely, that is, loose surfaces.

Leather inspection: first look at decolorization.

Choose the minor parts of leather clothing, such as the back of the collar, the inside of the clothes or the place of the garment. Wipe the water with cotton wool and press it with your hands. Choose a 10cm long part on the leather coat and rub it 20 times on the top of the cotton wool. Observe whether the cotton is stained with color. If the color is heavy, black or dark gray, it is a defective product.

Laboratory test: the general leather requires a wet wipe grade of three (see color comparison standard for leather inspection station).

Then look at the surface of the split surface, or in the secondary parts, rub with your hands for two or three minutes. After tightening, observe the leather surface, there is no crack, no drop, if there are cracks, slag phenomenon is unqualified.

You can also lift the leather surface with your fingers, while rubbing several top parts with your hands. For example, if the surface coating is off, the pulp will be broken, indicating that the coating is not firm.

Finally, look at the strength of the leather itself. The most important indicator of the strength of the leather is tear strength. When the lab is doing the experiment, it cuts a diamond hole on the leather, then hooks it on the drawing machine with two hooks, and tries to see if the hole continues to rip up under a certain pull.

Intuitive inspection can be based on this principle, a small incision in the minor part of the leather clothing, gently break with the hand, if the incision is deformed, it shows that the tear strength is not enough.

It can also pull the joints with medium strength. If there is a tendency to tear, it will be unqualified. It can also force the fingers to pull the top from the inside. If there are cracks and cracks, they are not qualified.

Leather accessories inspection: leather clothing life is very long, leather clothing accessories high quality requirements, zippers, buttons are generally copper top quality, leather lining is made of high quality silk.

The quality leather fur is soft, lubricated and elastic. The wrinkles that are pressed by hand can disappear very quickly. The thickness of the leather is uniform, comfortable, flat and crisp, not hard or soft.

Leather fur produced by glossy leather is soft, clear, smooth and light. It has become the main material for high quality fur production and is widely used in double needle sewing.
