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 peeled off from animals, like pigskin, faux leather material sheepskin, crocodile skin, and so on. The first 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. The upper part is processed into the 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 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 should identify from the aspects 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 is animal fibers in the low layer. Try together with your fingernails, you will have leather fibers, you will find a feeling of napping, and a small amount of fibers could be removed, and the faux leather can see the fabric, there is no animal fiber in the medial side, and the general epidermal does not have any pores, however, many are imitation leather pores, there will be 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 might be carefully observed by the aid of magnifying glass, or can see the fine difference.
Generally speaking, the costs of real leather (especially the first layer leather) are very much higher than PU leather, so is real leather has been far better properties than PU? The solution is not any. Real leather is expensive is because of 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.
