PU (polyurethane) faux (synthetic) leather material is using knitted fabrics, woven fabrics, or non-woven fabrics because the substrate and coated with polyurethane resin. The fabric can be utilized 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 cut the thick skin of cattle, pigs, horses, etc into upper and lower layers. Top of the part is processed in to the faux leather fabric first-layer of leather. The next 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 compared to the first layer of leather.
How exactly to distinguish real leather and PU leather?
First, we should identify from the areas of leather pattern, pores, etc. Is seen in the surface of natural leather, the pores do exist, and the distribution is uneven, there’s animal fibers, side section, and the layers are obvious, and there is animal fibers in the lower layer. Try with your fingernails, you will see leather fibers, there is a feeling of napping, and a small amount of fibers can 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, but some are imitation leather pores, you will have undesirable pores, a number of the patterns aren’t obvious, or have a compared artificial pattern, and the pores may also be quite consistent. At the moment, they could be carefully observed by aid from magnifying glass, or can easily see the fine difference.
Generally speaking, the costs of real leather (especially the first layer leather) are very higher than PU leather, so is real leather has been much better properties than PU? The solution is no. Real leather is expensive is due to its many reasons. Such as for example 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 USA, etc are highly respected and gradually choose innovative PU leather rather than real leather.
