What exactly is genuine leather?
Genuine leather is derived from animals, such as pigskin, sheepskin, or crocodile skin. The initial layer of leather is either produced directly from the raw skin of various animals or is cut into upper and lower layers from the thick skin of cattle, pigs, and horses, for example. The upper section is treated to create the initial layer of leather. The second layer of leather is composed of PU resin and the animal skin’s bottom layer of skin or waste material. The second layer’s hardness, hand feel, and abrasion resistance are significantly lower than those of the first layer of leather.
PU leather or genuine leather?
In general, real leather (particularly the first layer leather) is substantially more expensive than PU synthetic leather. Does this mean that real leather has superior characteristics to PU? No, that is not the case. Genuine leather is pricey for a variety of reasons. Such as limited resources and the time-consuming processing of animal hides. Natural leather can no longer reach many of the wonderful qualities of polyurethane leather, particularly solvent-free PU and DMF-free water-based PU, thanks to technological advancements.
