Along with the societal scientific disciplines and technical development, leather technology matures, the product quality greatly improved, particularly in the anti-leather front, permeability, tractableness, feel and show, and many other respects they are  to natural leather, but the price is far from lower than the natural leather, and therefore, in order to enhance our ability to identify now introduce some simple and direct method for reference:
Visual designation method: Firstly, from the leather pattern, pores and other aspects to identify, in natural leather pattern on the surface can be seen, the existence of pores, and uneven distribution, and negative with animal fiber, side cross-section, level clearly identifiable, test will appear with your fingers scraping leather fibers were put into the side of non-animal fiber, the general pore-free skin, but some man-made leather pores, the pores will be obvious existence of some patterns were not evident, or more regular pattern of artificial production, pores are also very similar.
Hand identification method: In fact, flexible leather handle, leather face down will be about 90 degrees bending occurs naturally fold, respectively, in different parts of bending, the resulting folding pattern thickness or less, with a clear uneven, can be basically determined that the leather, because leather has a natural fibrous tissue of non-uniform composition, so the performance of the formation of fold lines there was a marked uneven. The synthetic leather handle plastic, poor reversibility, variable fold down folding patterns are similar to rough.
Olfactory Perception Identification Law: Natural leather with a fur Yigu very strong flavor, even after treatment, more pronounced taste, while the leather products, there are stock plastic taste, no fur taste.
Burning identification method: primarily smell the ashes of burnt smell and look at the state, natural leather will be issued Yi Gu burning sense of burnt hair. The ashes of burnt powder into a in general fragile, while the leather, burning after the flame are more wang, shrink quickly, and a stock is difficult to hear the plastic taste, burning late-sticky after cooling into a hard block will be issued.
