Pu is polyurethane, and pu leather is polyurethane synthetic leather, which is often used to make bags, clothes, shoes, vehicles, car cushions, car mats, furniture, imitation leather sofas, etc. It is usually called artificial leather. The dermatoglyphics of PU leather are very similar to genuine leather, and it feels a little soft, so it is difficult for outsiders to tell whether it is genuine leather or regenerated leather. Pu leather is characterized by beautiful appearance and low price, but with the development of technology, Pu leather has also been made into various grades of varieties, and the price can be comparable to that of genuine leather.
Extended data:
PU leather is made from the second and third inner layers of natural leather and defective leather. After special film-forming and film-covering processes, the leather surface is covered with polyurethane PU, which makes the leather surface present various colors and patterns, without losing the advantages of leather breathability and folding resistance, and has its unique features in appearance and waterproof performance.
Ultra-fine fiber PU synthetic leather is the third generation of artificial leather. With its three-dimensional structural network, non-woven fabrics create conditions for synthetic leather to surpass natural leather in substrate.
This product combines the newly developed PU slurry impregnation processing technology with open-cell structure and composite surface layer, and exerts the huge surface area and powerful water absorption function of superfine fiber, so that superfine PU synthetic leather has the inherent moisture absorption characteristics of bundle superfine collagen fiber natural leather, and is comparable to high-grade natural leather in internal microstructure, appearance texture, physical characteristics and human wearing comfort.
