PU (polyurethane) faux (synthetic) leather material is using knitted fabrics, woven fabrics, or non-woven fabrics as the substrate and then coated with polyurethane resin. The fabric may 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 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. The upper part is processed in to the first-layer of leather. The next layer of leather is a combination of PU resin and the low layer of skin or scrap material of the animal skin. The toughness, handfeel, and abrasion resistance of the next layer are much lower than the first layer of leather.
How exactly to distinguish real leather and PU leather?
First, we must 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’s animal fibers, side section, and the layers are obvious, and there’s animal fibers in the low layer. Try with your fingernails, you will see leather fibers, there is a feeling of napping, and handful 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, however, many are imitation leather pores, you will have undesirable pores, some of the patterns are not obvious, or have a compared artificial pattern, and the pores are also quite consistent. At this time, they might be carefully observed by aid from magnifying glass, or can easily see the fine difference.
Generally speaking, the prices of real leather (especially the initial layer leather) are very much 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 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 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, PU leather fabric Europe and United States, etc are highly respected and gradually choose innovative PU leather rather than real leather.
