Development China's artificial leather synthetic leather industry is a new industry after the founding of the country, started to develop in the late fifties, and it is one of the earlier developing industries in the plastics industry. After nearly decades of construction, artificial leather synthetic leather industry has a considerable economic scale; with the development of high technology at home and abroad and the application of advanced technology and equipment, the industry management, technical level, product grade have made a fundamental qualitative leap, artificial leather synthetic leather has developed into an important industry in the daily consumption products industry, and the whole processing industry synchronization into the ranks of the world's big countries, is the world's production and consumption of big countries, import and export trade of big countries, is a world production and consumption of big countries. It is one of the big countries in the world in terms of production, consumption and import and export trade.
1, artificial leather synthetic leather industry distribution characteristics and explanation
1.1 enterprise regional distribution is relatively concentrated in the developed metropolitan area of Jiangsu, Zhejiang, Guangdong and so on
China's artificial leather synthetic leather production enterprises are mainly located in the Pearl River Delta, the Yangtze River Delta, and the three places of Beijing, Tianjin and Hebei, as well as Hunan, Shandong Peninsula, and other coastal areas of the developed provinces and cities. National artificial leather synthetic leather above-scale enterprises nearly a thousand, we analyze the information of more than 400 enterprises: which the total number of enterprises in East China and Central and South China occupy more than 60% of the total number of enterprises in Jiangsu Province, Zhejiang Province, more than two hundred, Hebei Province, there are more than thirty. According to the incomplete statistics summary: mainly concentrated in coastal areas and provincial cities and metropolitan areas, the Wenzhou synthetic leather capital area developed in the Wenzhou model there are more than one hundred, in the form of Jiangnan model of Zhouzhuang town artificial leather production base there are 22.
1.2 Production energy has increased tremendously with the modernization level of large-scale enterprises leading
At present, the domestic artificial leather synthetic leather domestic production equipment has information printed on 1000 sets (sets), imported equipment is mainly from Italy, Japan, South Korea, Hong Kong, Taiwan and other countries and regions. Domestic and foreign joint venture and domestic equipment production capacity, production technology has fully reached the advanced level of developed countries. Microfiber synthetic leather and breathable leather has led the market. 2001 synthetic leather production of 510,000 tons of synthetic leather, such as Jiangsu PVC synthetic leather synthetic leather production in 2001 accounted for 35.7%; Guangdong accounted for 26.8%, Zhejiang accounted for 17.6%; for example, PU synthetic artificial leather synthetic leather production of 131,000 tons in the year before last; Zhejiang accounted for 35.1%, Guangdong accounted for 19.5%, Jiangsu accounted for 20.6%. Among them, functional medium and high-grade products accounted for one-third. Practical artificial leather synthetic leather mostly. Our statistical analysis of the national enterprise to see there are 107,000 industrial workers, to achieve annual sales of more than 15 billion, the total assets have reached more than 12 billion, the economic benefits continue to grow.
1.3 Artificial leather synthetic leather multi-body composite manufacturing industry chain formation
Artificial leather synthetic leather industry chain has formed thousands of upstream raw materials and tens of thousands of downstream manufacturers, and artificial leather synthetic leather is not only affiliated with the plastics industry, but also in the distribution of leather systems, textile systems, the army, transportation and other systems. In addition artificial leather synthetic leather production and manufacturing is a highly specialized study, involving the application of dozens of plastic polymer materials, inorganic filler media, different types of textile fabric base theory, intelligent automation applications, printing profession, paint industry, garment industry, footwear industry and other humanistic theories; product pattern design to apply aesthetics, literalism, plants, animals, nature, geometry and other related cultural knowledge. In the manufacturing process for PVC resin, PU resin, DOP plasticizer and other upstream raw materials such as molecular weight and other values, characteristics to have a more in-depth study, especially microfiber, breathable leather research should also be based on the understanding of the structure of the natural leather in order to better design its microporous structure. Artificial leather synthetic leather production process is quite complex, calendering method, coating and scraping method, casting method, steel banding method and post-treatment process art spraying, overlaying, printing, flocking, grinding, embossing and so on dozens of process routes. The physical properties, chemical properties, texture, feel and visual effect of artificial leather synthetic leather have reached the performance of animal skin, which is the crystallization of human productivity and wisdom. There are more than 3,000 varieties of artificial leather synthetic leather, and the downstream products are more and more widely used, involving aerospace field, diving industry, transportation, sports equipment, medical equipment, building materials, including bag fabrics, shoe fabrics, garment fabrics, sofa fabrics and so on, which are necessary for people's daily life. Developed nano-materials used in artificial leather synthetic leather, radiation-resistant synthetic leather, anti-infrared synthetic leather, as well as anti-odor, mildew, acid, alkali, aging and other functions to change the status quo of the traditional product monomerization for the development of artificial leather synthetic leather industry opened a new page in history. Fields of application According to the different kinds of coverings, there are polyvinyl chloride artificial leather (PVC), polyurethane artificial leather (PU) and so on. It can be used for almost any occasion where leather is used instead of leather, and is used for making daily necessities and industrial goods. According to whether the covering layer is foamed or not, there are foam artificial leather and variant artificial leather. According to the use, there are artificial leather for shoes, artificial leather for bags and other roots.
China's artificial leather in the past few years has achieved a relatively rapid development, but from the industry as a whole, there are still many problems, such as small-scale producers with poor environmental protection, heavy pollution, low value-added products, and insufficient innovation capacity. China Artificial Leather Synthetic Leather Industry Production and Sales Demand and Investment Opportunity Analysis Outlook" points out that eco-functional polyurethane synthetic leather emphasizes both functionality and environmental protection, which represents the future development direction of synthetic leather industry. In the future development, enterprises should pay attention to the improvement of overall strength, product quality and technological innovation, through increasing R & D investment, improve the existing level of product technology and the industry environment, to provide the market with more and better ecological functional polyurethane synthetic leather, so that China's synthetic leather industry continues to develop in a healthy manner.
