pu leather

　　In China, people used the PU resin as raw leather called PU leather (PU leather short); PU resin and non-woven materials for the production of artificial leather called PU synthetic leather (referred to as synthetic leather). Customarily referred to as the three leather synthetic leather. In the end how to name? Everyone to be unified and standardized in order to give it a more appropriate name.
　　Leather, synthetic leather is an important part of the plastics industry, is widely used in various sectors of the national economy. Leather, synthetic leather production in the world more than 60 years of development history of China since 1958, started to develop the production of artificial leather, which in Chinese plastics industry is the development of early industry. In recent years, the development of Chinese leather, synthetic leather industry is not only the growth of the production of business equipment production lines, product output growth year after year, year after year increase in variety of colors, and the process of development of the industry has its own trade organization, there is considerable cohesion, thereby can Chinese leather, synthetic leather enterprises, including relevant industry organizations together to develop into a considerable strength of the industry.
　　Following the PVC artificial leather, PU synthetic leather through science and technology experts 30 years of painstaking research and development, as the ideal substitute for natural leather, it was a breakthrough technological advances.
　　PU coated fabric surface first appeared on the market in the 1950s, to 1964, DuPont developed for use as a shoe upper PU synthetic leather. After the Japanese company has established an annual output of 600,000 square meters of production lines, after 20 years of continuous research and development, PU synthetic leather in terms of product quality, variety, or yields have been rapidly growing. Its performance is closer to natural leather, some performance even more than natural leather, to the extent of natural leather doubtful, and occupies a very important position in the human daily life.
　　Today, Japan is the largest producer of synthetic leather, Kuraray, Teijin, Toray, Kanebo, several representatives of the company's products are basically the level of development of international 1990s. Its fibers and nonwoven fabric manufacturing toward ultrafine, high density and high non-woven effect direction; toward its manufacture PU PU dispersions, PU aqueous emulsion direction of development, product applications continue to expand, from the beginning of shoes, bags development of the field to the other special applications apparel, balls, decoration, etc., all over people's daily lives.
