Synthetic leather is a plastic product that simulates the composition and structure of natural leather and can be used as its substitute. It is usually made of impregnated non-woven fabric as the mesh layer and microporous polyurethane layer as the particle surface layer. Its front and back sides are very similar to leather, and have certain permeability, which is closer to natural leather than ordinary artificial leather.

The appearance of superfine fiber PU synthetic leather is the third generation of artificial leather. The non-woven fabric of its three-dimensional structure network creates conditions for synthetic leather to catch up with and surpass natural leather in terms of substrate. Combined with the newly developed processing technology of Pu slurry impregnation and composite surface layer with open pore structure, this product plays a huge surface area and strong water absorption role of ultra-fine fibers, making ultra-fine PU synthetic leather have the inherent moisture absorption characteristics of natural leather with fascicular ultra-fine collagen fibers. Therefore, no matter from the aspects of internal microstructure, appearance texture, physical properties and people’s wearing comfort, Can be compared with high-grade natural leather. In addition, superfine fiber synthetic leather is better than natural leather in chemical resistance, quality uniformity, mass production and processing adaptability, waterproof and mildew resistance.
Practice has proved that the excellent properties of synthetic leather can not be replaced by natural leather. From the analysis of domestic and foreign markets, synthetic leather has also replaced a large number of natural leather with insufficient resources. The use of artificial leather and synthetic leather for the decoration of bags, clothing, shoes, vehicles and furniture has been increasingly recognized by the market. Its wide range of applications, large number and many varieties are beyond the traditional natural leather.
