Natural leather is widely used due to its excellent natural properties, but with the doubling of human demand for leather, natural leather can no longer meet people's needs. To solve this contradiction, scientists began researching and developing synthetic leather and synthetic leather decades ago to compensate for the shortcomings of natural leather.
Scientists first produced nitrocellulose lacquer cloth and used it to develop PVC synthetic leather, which is a generation of artificial leather products. By the 1970s, the surface of synthetic leather was able to achieve a natural grain effect, gradually bringing the appearance and internal structure of PU leather closer to natural leather, while the color was more vibrant than natural leather.
Ultra fine fiber PU synthetic leather is the third generation of artificial leather. The non-woven fabric with its three-dimensional structural network has created conditions for synthetic leather to surpass natural leather in terms of substrate. This product combines the newly developed PU slurry impregnation and composite surface layer processing technology with an open pore structure, and utilizes the huge surface area and strong water absorption of ultrafine fibers, making ultrafine PU synthetic leather have the inherent moisture absorption characteristics of natural leather with bundle shaped ultrafine collagen fibers. Therefore, whether from the internal microstructure, appearance texture, physical properties, and people's wearing comfort, it can be comparable to high-end natural leather. In addition, ultra-fine fiber synthetic leather surpasses natural leather in terms of chemical resistance, quality uniformity, adaptability to large-scale production and processing, as well as waterproofing, mildew resistance and degeneration.
