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

Real leather is taken off from animals, like pigskin, sheepskin, crocodile skin, and so forth. The initial 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. The upper part is processed into the first-layer of leather. The second layer of leather is really a combination of PU resin and the lower layer of skin or scrap material of the animal 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 aspects 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 obvious, and there is animal fibers in the low layer. Try with your fingernails, you will see leather fibers, you will find a feeling of napping, and handful of fibers could be removed, and the faux leather can easily see the fabric, there is absolutely no animal fiber in the side, and the general epidermal has no pores, but some are imitation leather pores, you will see undesirable pores, a number of the patterns aren’t obvious, or have a compared artificial pattern, and the pores are also quite consistent. At the moment, they may be carefully observed by the aid of magnifying glass, or can easily see the fine difference.

Generally speaking, the prices of real leather (especially the first layer leather) are very much higher than PU leather, so is real leather is with much 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 cannot 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 United States, etc are highly respected and gradually choose innovative PU leather rather than real leather.
