In 2008, the development of leather was more and more inclined to the following aspects: the concept of developing ecological leather in the direction of eco leather includes the following four aspects: first, the ecological leather does not pollute the environment in the manufacturing process; second, it is harmless in the process of processing leather products; third, it is harmless to human body and pollute the environment in the process of use; fourth, it can be biodegraded, and the degradation products will not cause new pollution to the environment. In the production process, the leather industry will pay more attention to the application of cleaner production technology, which requires the development of green chemicals and pollution-free technology, and pay attention to reuse and recycling in the process. High and new technology is more and more embodied in the leather industry, such as ultrasonic technology, electronic technology, microwave and high pressure technology. It has been applied to leather industry. The future nano technology will also be applied to leather making process, and it will also have great influence on leather design and manufacture. For example, sonic technology can make leather more uniform and can make the enzyme transferable, and also can reduce the waste of leather. The technology of ultra wave will be more easily penetrated into leather. Sichuan University has also studied in this area and has achieved initial success. The application of nanotechnology in leather will also be gradually expanded. In this regard, Sichuan University and Shaanxi University have discussed and achieved initial results, such as the development of nano tanning agents. Special effects leather and special leather are constantly being applied. At present, the special effects of leather in the market are wrinkle (chapped) leather, wrestling leather, rub effect leather, matting leather, pearlescent leather, fluorescent effect leather, pearl coloring effect leather, imitation old effect leather, crystal leather (imitation polishing), frosted leather, Lizard Leather, chameleon leather, suede leather and so on. The technology of textile industry and other industries, such as flower catching, flower binding, batik dyeing, tie dyeing, hollowing out, electronic carving and so on, has been transplanted into the leather industry. The production of special effects leather has also become a trend.
