PU (polyurethane) faux (synthetic) leather material is using knitted fabrics, woven fabrics, or non-woven fabrics as the substrate and coated with polyurethane resin. faux 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, etc. 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. 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 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 should identify from the areas of leather pattern, pores, etc. Can be seen in the top 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 lower layer. Try with your fingernails, there will be 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, you will see undesirable pores, a number 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 the aid of magnifying glass, or can easily 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 is with far better properties than PU? The answer is no. 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 United States, etc are highly respected and gradually choose innovative PU leather rather than real leather.
