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 can be utilized for a wide range such as 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 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 really a combination 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 than the first layer of leather.
How exactly to distinguish real leather and PU leather?
First, we must identify from the areas of leather pattern, pores, etc. Can be 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, you will find a feeling of napping, and a small amount of fibers could be removed, and the faux leather can easily see the fabric, there is absolutely no animal fiber in the side, and the general epidermal does not have any 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. read more At this time, they could be carefully observed by aid from magnifying glass, or can see the fine difference.
Generally speaking, the costs of real leather (especially the first layer leather) are very higher than PU leather, so is real leather has been 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 USA, etc are highly respected and gradually choose innovative PU leather rather than real leather.
