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 utilized for a wide range such as shoes, apparel, furniture, handbags etc.
Real leather is peeled off from animals, faux leather material like pigskin, sheepskin, crocodile skin, and so on. The initial layer of leather is directly processed from the raw skin of varied animals or slice 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 second layer of leather is 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 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 obvious, and there’s animal fibers in the lower layer. Try together with your fingernails, you will see leather fibers, there exists a feeling of napping, and handful of fibers could be removed, and the faux leather can easily see the fabric, there is absolutely 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 may be carefully observed by aid from magnifying glass, or can easily see the fine difference.
Generally speaking, the prices of real leather (especially the first layer leather) are very higher than PU leather, so is real leather is with much better properties than PU? The answer 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.
