Recognition of artificial leather

April 22 , 2022

Compared with finished leather products, it will be relatively difficult to distinguish between artificial leather and genuine leather, especially when the structure is compact and the area is small, so we can’t see the leather products inside. The first way to distinguish this kind of products is: first look at the appearance, no coarse grain, no disability and no defects. It is very likely that artificial leather has some differences in the texture of leather, In particular, the differences in the joints of secondary parts and main parts of leather products should be more obvious After that, we will carefully observe the distribution and shape of pores. Natural leather has more and deeper pores, which are not suitable to see to the bottom, and slightly inclined. Where the pores are vertical and shallow, it may be modified leather synthetic leather In addition, in terms of cross section, the main cross-sectional fibers of natural leather have their main characteristics, and there are great changes in fiber thickness Compared with synthetic leather, the fiber layer is very uniform, and the surface layer is plastic film
First of all, in terms of pores and patterns of leather, if you can identify them, you can see that pores and patterns really exist on the surface of natural leather, but the distribution is not very uniform. On the reverse side, there are animal fibers, side sections and layers. On the lower layer, there are animal fibers. When we scrape with our fingernails, there will be the erection of leather fibers and the feeling of flocking, A small amount of fiber can fall down, and the fabric can be seen on the back of synthetic leather, and there is no animal fiber on the side, Generally speaking, there are no pores in the epidermis, but there are many imitation leather artificial pores with an indistinct pore, which is not very obvious in the pattern, and there are relatively regular artificial patterns, and the pores are also very consistent
Hand feeling identification method: secondly, the leather feels elastic. When the front of the leather is bent down for about 90 degrees, there will be natural wrinkles. When different parts are bent respectively, the thickness and number of creases are obviously uneven. It can be basically recognized that this is leather, because the leather has natural uneven fiber tissue composition, so the wrinkle lines are also obviously uneven. Synthetic leather feels like plastic and has poor recoverability. When it is bent, the crease thickness is more or less similar.
In terms of hand feel, the identification is that the leather is very elastic in hand feel, and there are often wrinkles when we bend the front of the leather down about 90 degrees. When we bend different parts respectively, the crease thickness and how much will produce obvious unevenness. Fundamentally, it can be recognized as leather. Because the real leather has the natural unevenness characteristics, Therefore, there is a very obvious non – uniformity in the formation of wrinkles Moreover, some synthetic leather feels like plastic, and some have relatively poor recoverability. When bending down, the crease thickness is more or less similar
For natural leather, there are mainly odor identification methods to identify all natural leather with strong fur flavor. Even after treatment, it will be obvious in taste. In terms of artificial leather products, it actually has a plastic taste and a fur free taste When we smell the burnt smell and look at the ashes, the main state is that after the natural leather is burned, it will release a smell of burnt hair. After burning, the ashes are usually easier to break into a kind of powder. In terms of artificial leather, it will gradually flourish with the fire after burning, and shrink rapidly. It also has a very unpleasant smell of plastic, which will become sticky after burning, It hardens and forms lumps after cooling
