Due to its excellent natural characteristics, it is widely used in the production of daily necessities and industrial products, but with the growth of the world’s population, human demand for leather has doubled, and the limited number of natural leather has long been unable to meet people’s needs. In order to solve this contradiction, scientists began to research and develop artificial leather and synthetic leather decades ago to make up for the shortage of natural leather. More than 50 years of research history is the process of artificial leather and synthetic leather challenging natural leather.
Scientists started by studying and analyzing the chemical composition and structure of natural leather, starting from nitrocellulose varnished cloth, and entering into PVC artificial leather, which is the first generation of artificial leather. On this basis, scientists have made many improvements and explorations, the first is the improvement of the substrate, followed by the modification and improvement of the coating resin. In the 1970s, the non-woven fabrics of synthetic fibers appeared acupuncture, bonding and other processes, so that the substrate had a lotus-shaped section and a hollow fiber shape, achieving a porous structure, which was in line with the network structure of natural leather. Requirements: At that time, the surface layer of synthetic leather can already achieve a micro-porous structure polyurethane layer, which is equivalent to the grain surface of natural leather, so that the appearance and internal structure of PU synthetic leather are gradually close to those of natural leather, and other physical properties are close to those of natural leather. index, and the color is more bright than natural leather; its folding resistance at room temperature can reach more than 1 million times, and the folding resistance at low temperature can also reach the level of natural leather.
After PVC artificial leather, PU synthetic leather has achieved breakthrough technological progress as an ideal substitute for natural leather after more than 30 years of research and development by scientific and technological experts.
The PU coating on the surface of the fabric first appeared on the market in the 1950s, and in 1964, DuPont developed a PU synthetic leather for shoe uppers. After more than 20 years of continuous research and development, PU synthetic leather has grown rapidly in terms of product quality, variety and output. Its performance is getting closer and closer to natural leather, and some properties even exceed natural leather, reaching a level that is indistinguishable from natural leather, and occupies a very important position in human daily life.
Microfiber polyurethane synthetic leather is the third generation of artificial leather that has appeared in the domestic and international markets. The non-woven fabric of its three-dimensional structure network creates conditions for synthetic leather to surpass natural leather in terms of substrate. This product combines the newly developed PU slurry impregnation with open-pore structure and the processing technology of composite surface layer, which exerts the huge surface area and strong water absorption of superfine fibers, making the superfine PU synthetic leather with bundled superfine The inherent hygroscopic properties of natural leather of collagen fibers can be compared with high-grade natural leather in terms of internal microstructure, appearance, texture and physical properties, as well as people’s wearing comfort. In addition, microfiber synthetic leather surpasses natural leather in chemical resistance, quality uniformity, large-scale production and processing adaptability, and waterproof and mildew resistance.
Practice has proved that the excellent properties of synthetic leather cannot 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 as the decoration of luggage, clothing, shoes, vehicles and furniture has been increasingly recognized by the market.
