PU (polyurethane) faux (synthetic) leather material is using knitted fabrics, woven fabrics, or non-woven fabrics because the substrate and coated with polyurethane resin. https://walterychina.com/what-is-pu-leather/ The fabric can 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 on. 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 in to the first-layer of leather. The second layer of leather is a combination of PU resin and the lower layer of skin or scrap material of the pet skin. The toughness, handfeel, and abrasion resistance of the next 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 areas of leather pattern, pores, etc. Is seen in the surface 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 together with your fingernails, you will see 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, you will have undesirable pores, a number of the patterns aren’t obvious, or have a compared artificial pattern, and the pores are also quite consistent. At this time, they might be carefully observed by the aid of magnifying glass, or can easily 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 has been much 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 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 rather than real leather.
