PU (polyurethane) faux (synthetic) leather material is using knitted fabrics, woven fabrics, or non-woven fabrics because the substrate and then coated with polyurethane resin. The fabric can be used for a wide range such as shoes, apparel, furniture, handbags etc.
Real leather is taken off from animals, like pigskin, sheepskin, read more crocodile skin, and so forth. The first layer of leather is directly processed from the raw skin of varied animals or cut 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 second layer of leather is really a mix 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 compared to the first layer of leather.
How to distinguish real leather and PU leather?
First, we must identify from the aspects of leather pattern, pores, etc. Can be seen in the top 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 low layer. Try with your fingernails, you will have 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 medial side, and the general epidermal has no pores, but some are imitation leather pores, you will see undesirable pores, a few of the patterns aren’t obvious, or have a compared artificial pattern, and the pores may also be quite consistent. At the moment, they are often carefully observed by the aid of magnifying glass, or can see the fine difference.
Generally speaking, the costs of real leather (especially the initial 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 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 United States, etc are highly respected and gradually choose innovative PU leather instead of real leather.
