Identification Of Artificial Leather And Genuine Leather

First, how to identify

1. the distinction between dermis and dermis: the pores of cattle hide are small, round, tight, uniform, and irregular "full sky star" arrangement. The pores are not deep and straight into the leather surface; the buffalo skins are rough and the pores are deeper and thicker than the yellow cattle leather, and the quality of the leather is more relaxed than that of the yellow cattle leather; the sheep skin pores are numerous, and the sebaceous glands and sweat glands are also numerous.

Porcine skin pores are sparse, deep and thick, and are tilted into leather.

The leather is rough and uneven.

The horse hide is similar to the cow leather, but there are still differences. The pores of the horse hide are oval, larger than those of Mao Konglve, and are arranged in a mountain range.

The horse's skin is thin and its fastness is not as good as that of cowhide.

But permeability and hygroscopicity are good, and there will be no stuffiness when wearing.

2. the distinction between genuine leather and imitation leather: there are pores in the dermis, and the more obvious the more, the imitation leather has no pores. Although the surface sometimes simulate skin pores to suppress patterns, there will be no pores.

(three) for grain surface modification, the original characteristics should be carefully classified and identified according to the processing technology.

Mainly from the following two aspects.

1. cross section observation: mild shaving leather can still see shallow pores on the surface, and the surface pores are more obvious with hands, so they can be distinguished according to pores.

Hikaruzawa Youwa, nature, touch no plastic feeling.

重度修面、涂饰的革其表面则不再有毛孔，无法根据毛孔去辨别真皮、仿皮，此时可根据截面进行辨别：真皮截面没有明显的薄膜层，用手刮擦其底基会发现有绒毛且愈刮愈变长，这是最明显的纤维底基(真皮底基)的表现;移膜革革是在天然皮革下层的疏松肉面纤层上贴上人造的表面层，不能称"真皮"，而是以天然皮革里层作底基的合成革，虽然底基也是真皮纤维，但其表面有一层很厚的塑料膜，其与真皮底基有明显的分层;再生革(如超纤)则是将皮渣、皮纤维磨碎，经高压用粘合剂粘合，形成片状，然后经片皮机片到需要厚度作为底基，再进行涂饰而制成的，因此该底基是不可能愈刮愈长的，而且刮一块则“空”一块，手摸有挺而滑且腻的感觉，同时再生革的表面塑料膜较移膜革要薄的多，这也是区分两者的一条好办法;而人造革与合成革其表面膜与再生革相似，但其

The bottom base is different, generally it is no harm to cloth (usually organic County Committee to suppress) and fabric (such as needle woven cloth, etc.), this point is very good to distinguish.

2. for the finished products with no cross section, the leather and imitation leather should be started from the leather surface only.

Hand touch, artificial material has a strong sense of plastic and bright luster. It feels hard and crisp and cold in winter, and the skin is smooth and delicate. It feels thick and strong without cold feeling, and some even feel soft and warm (e.g. sheepskin).

Eye view: under normal circumstances, shaving leather (including aniline leather, pearlescent leather, etc.) is bright and soft on the surface. The imitation leather is bright and dazzling, and the plastic feeling is very strong. When the leather is wiped on the face, its surface will shine brightly, but not the natural leather will not change obviously.

At the same time, the surface of the moving leather will have a rough feeling on its surface (such as the Baotou position of the finished product), which is similar to the skin of the axillary part of the leather, while other leather will not have such a phenomenon.

It is important to distinguish between shaving leather and grain leather. Shaving leather destroys the original grain layer and then presses the pattern. Although the pattern can imitate cattle, sheep, pig skin and so on, the pattern has no pores, the patterns are floating on the skin surface, and the pores of the grain leather are present. Careful observation can identify them.

At the same time, although the shape and arrangement of grain leather have certain rules to check, but because it is natural, in general, it is still disordered, and the surface of the shaving leather and non natural leather is printed by a mold, which is exactly the same.

Under normal circumstances, the difference between shaving leather and non natural leather is very difficult to distinguish from the perspective of pores. It should be avoided by other means, such as hand model, eye view, hand press and small beads.

Hand press: press the product soft parts with your hands. There will be a lot of small and even wrinkles around the thumb, and the thumb will open. Due to the good elasticity of the skin, the surface wrinkles will recover very quickly, leaving only a few wrinkles. Instead of natural leather, there will be no wrinkles or even wrinkles.

By placing small droplets on the surface of the finished product, after a few minutes, the water droplets on the dermal surface will diffuse through the pores, which can see obvious wet spots and absorb moisture, while natural leather will not have such a phenomenon.

Wen: the dermis has the smell of animal fat (that is, the smell of the skin), and the imitation leather is made of plastic or rubber.

Burn: burn the skin on the sides with hair, and the imitation leather is plastic.

According to the leather layer, there are two kinds of leather, including the first layer and the second layer. The top layer leather consists of grain leather, shaving leather, embossed leather, special effect leather and embossed leather. The two layer leather is divided into two layers of pig and two layers of leather.

(1)

Shaving leather: it is made by using a leather grinding machine to coat the surface and then press the corresponding pattern.

In fact, it is "cosmetic" for the natural leather surface with disability or roughness.

This kind of leather almost lost its original surface state.

Full grain leather characteristics: soft leather, wrinkled leather, front leather and so on.

It is characterized by complete retention of granules, clear pores, fine, tight, irregular arrangement, plump and delicate surface, elastic and good air permeability. It is a high-grade leather.

Leather products made from this cowhide are comfortable, durable and beautiful.

Half grain leather characteristics: during processing, only half of the grain is processed and grinded, so it is called half grain leather.

It keeps some of the natural leather's style. The pores are flat and oval, irregular in arrangement, and hard in hand. Generally, the raw materials with poor grades are chosen.

So it belongs to mid-range leather.

Due to the particularity of the process, its surface has no disability and scars, and its utilization rate is high. Its finished products are not easy to deform, so they are generally used in large box products.

Shaving cowhide characteristics: also known as "smooth cowhide", the market is also known as fog surface, bright surface cowhide.

It is characterized by smooth, smooth surface, no pores and skin veins. In the process of making, the surface of the surface is slightly grind and modified, and a coloured resin is sprayed on the leather to hide the surface texture of the leather, and then spray the waterborne light penetrating resin, so it is a high-grade leather.

In particular, the bright, elegant and gorgeous style of bright leather is the popular leather of fashion leather.

Special effect leather characteristics: the manufacturing process requires the same finishing cowhide. Only the colored resin is coated with beads, metal aluminum or metallic copper without any ingredients to spray the leather synthetically, and then roll a layer of waterborne pparent resin. The finished products have various luster, bright colors, beautiful and luxurious villages, and are popular leather, belonging to medium grade leather.

Characteristics of embossed cowhide: use patterned flower plates (aluminum and copper) to warm the leather surface to suppress various patterns and make them into a style of leather.

At present, the market is popular with "litchi pattern cowhide", which is to use a flower plate with a litchi pattern, and the name is also called "litchi pattern cowhide".

It is thick skinned with a leather machine. The top layer is used to make full grain leather or shaving leather. The two layer is made of two layers of leather after finishing or laminating. Its fastness and wear resistance are poor. It is the cheapest kind of leather.

Two layers of cowhide characteristics: the reverse is cowhide's second layer leather material, coated with a layer of PU resin on the surface, so it is also called the film skin.

Its price is cheaper and its utilization rate is high.

With the change of technology, it has also been made into various grades, such as imported two layers of cowhide. Because of its unique technology, stable quality and novel varieties, the price and grade of the top grade leather are no less than that of the top layer of leather.
