PU (polyurethane) faux (synthetic) leather material is using knitted fabrics, woven fabrics, or non-woven fabrics because the substrate and coated PU leather with polyurethane resin. The fabric may be used for a wide range such as for example shoes, apparel, furniture, handbags etc.

Real leather is taken off from animals, like pigskin, sheepskin, crocodile skin, and so forth. The first layer of leather is directly processed from the raw skin of various animals or slice the thick skin of cattle, pigs, horses, etc into upper and lower layers. Top of the part is processed into the first-layer of leather. The next layer of leather is really a combination of PU resin and the low layer of skin or scrap material of the pet skin. The toughness, handfeel, and abrasion resistance of the second layer are much lower than the first layer of leather.

How to distinguish real leather and PU leather?

First, we should identify from the areas of leather pattern, pores, etc. Is seen in the top of natural leather, the pores do exist, and the distribution is uneven, there is animal fibers, side section, and the layers are clear, and there’s animal fibers in the low layer. Try with your fingernails, there will be leather fibers, there exists a feeling of napping, and a small amount of fibers could be removed, and the faux leather can see the fabric, there is absolutely no animal fiber in the side, and the general epidermal does not have any pores, however, many are imitation leather pores, there will be undesirable pores, some of the patterns aren’t obvious, or have a compared artificial pattern, and the pores are also quite consistent. At the moment, they are often carefully observed by aid from magnifying glass, or can see the fine difference.

Generally speaking, the prices of real leather (especially the first layer leather) are very higher than PU leather, so is real leather is with far better properties than PU? The answer is not any. Real leather is expensive is due to its many reasons. Such as scarce sources and tedious processing of animal skins. Nowadays with the development of technology, nature leather can not achieve many excellent properties of PU leather especially solvent-free PU and DMF-free water-based PU. Because of their excellent physical & chemical properties, healthy & eco-friendly & animal-friendly performance, good uniformity, etc, Europe and USA, etc are highly respected and gradually choose innovative PU leather instead of real leather.
