Identification Of Genuine Leather And Imitation Leather

Unmodified leather.

1).

2) dermis and

3) for grain surface modification, the original characteristics should be carefully classified 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、涂飾的革其表面則不再有毛孔，無法根據(jù)毛孔去辨別真皮、仿皮，此時可根據(jù)截面進行辨別：真皮截面沒有明顯的薄膜層，用手刮擦其底基會發(fā)現(xiàn)有絨毛且愈刮愈變長，這是最明顯的纖維底基(真皮底基)的表現(xiàn);移膜革革是在天然皮革下層的疏松肉面纖層上貼上人造的表面層，不能稱"真皮"，而是以天然皮革里層作底基的合成革，雖然底基也是真皮纖維，但其表面有一層很厚的塑料膜，其與真皮底基有明顯的分層;再生革(如超纖)則是將皮渣、皮纖維磨碎，經(jīng)高壓用粘合劑粘合，形成片狀，然后經(jīng)片皮機片到需要厚度作為底基，再進行涂飾而制成的，因此該底基是不可能愈刮愈長的，而且刮一塊則“空”一塊，手摸有挺而滑且膩的感覺，同時再生革的表面塑料膜較移膜革要薄的多，這也是區(qū)分兩者的一條好辦法;而人造革與合成革其表面膜與再生革相似，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.
