China Polypropylene Industry Status and Prospects
China Chemical Fiber Industry Association Polypropylene Professional Committee
1 . Foreword
Polypropylene is the youngest member of the four synthetic fibers. Because of its low density, low melting point, high strength, and resistance to acids and alkalis, polypropylene is widely used in clothing, decoration, and industry.
The development of the chemical fiber industry in the future has satisfied the basic needs of the first chemical fiber as clothing, and has already shifted to a higher level of development, such as high-performance fibers for industrial use and high comfort fibers for clothing. As far as several major chemical fiber varieties are concerned, polypropylene is undoubtedly a very successful product in terms of production cost, production technology, and the increasingly demanding environmental and ecological requirements. Compared with polyester, polyamide, and acrylic, polypropylene has the advantages of low energy consumption, low cost, and no pollution because of its single raw material, short process route, and simple spinning process. Under the current situation of “energy saving and emission reductionâ€, Polypropylene industry will usher in a good opportunity for development.
2 . China's polypropylene industry status
In the past few years, the application of new technologies and the continuous development of new products have made polypropylene increasingly important in the application of the textile industry. Polypropylene and its fibers have rapidly entered the new product market and are very good. Consolidate the status of end-use. The consumption trend of polypropylene fibers is mainly reflected in the sharp increase in the demand for flexible semi-finished bulk carriers, health care products, agricultural textiles and automotive filter materials; carpets, geotextiles and construction textiles, apparel, medical and rope products all have The rising trend, especially the development of fine denier and functional fibers, has expanded its application in the field of administration. In terms of material substitution and new applications, the rapid development of non-woven products remains unprecedented, especially the application of health care products. As the demand for disposable products increases, polypropylene fibers will also grow further. The development of new technologies for polypropylene fiber will make the variety more and more new and more and more.
On the other hand, with the continuous development of raw material polypropylene production technology, polypropylene will also provide more raw material choices. At present, all major polypropylene companies in the world are committed to the research and development of new production processes and new catalysts in order to increase the competitiveness of their products in the market. In recent years, polypropylene companies in the region have also made remarkable achievements in the development and production of new products. For example, Jiujiang Petrochemical Company's transparent polypropylene special materials can replace similar imported products. The transparency and heat resistance of the products have reached the domestic advanced level of similar products. Its radiation resistance has broken the current domestic tradition of UV and electromagnetic radiation, reaching the domestic leading level. At the same time, the innovation of processing and modification technology has also created the conditions for the upgrading of polypropylene products, which will further consolidate the growth and growth of the polypropylene-polypropylene industrial chain, and make greater contributions to the healthy development of our chemical fiber industry.
In 2008 , due to the ups and downs of crude oil prices, polypropylene also staged a roller coaster-like market. In addition, due to the impact of the global economic crisis, downstream demand has shrunk, but the polypropylene industry compared to other chemical fiber varieties, the degree of export Not high, the direct impact of the financial crisis is still relatively small, but the slowdown in the downstream textile industry slowed down the impact on the demand for polypropylene still exists, some companies have stopped production, reduced production. According to the statistics of the National Bureau of Statistics, in 2008 the national production of polypropylene was 266,400 tons. However, it is understood that this figure is obviously small. According to incomplete statistics, China's polypropylene fiber production capacity was about 580,000 tons in 2008 . The products include filaments, staple fibers, industrial yarns, BCF , tobacco tow, etc., of which polypropylene filaments are the main, accounting for about 43% . The production capacity of major filament companies is shown in the table below.

3 . China Polypropylene Industry Leading Enterprises
Fujian Sanhong Renewable Resources Technology Co., Ltd. is a wholly foreign-owned enterprise specializing in the production of polypropylene fiber and integrating scientific research, production and operation. The company's renewable resource recycling technology has passed several years of experience accumulation and technology precipitation. Its technical level and annual output rank among the top in the industry. It is the country's largest exporter of renewable fiber polypropylene filament, and it is also a cycle in Fujian Province. Economic enterprises. In 2008 , the total output of polypropylene fiber was 20,000 tons. In 2009 , the company expanded its production scale and increased investment in equipment and technology. The total output of polypropylene fiber is expected to reach 23,000 tons. Comprehensive analysis of the national polypropylene industry's production strength and production scale, San Hong company is the largest domestic polypropylene filament production enterprises, and its production equipment is also the most advanced one-step spinning production equipment.
4 . China Polypropylene Industry Development Trend
With the introduction of the “Tune and Adjustment Plan for the Textile Industryâ€, an unprecedented emphasis has been placed on opening a new round of development of industrial textiles. In the next three years, geotextile materials, environmental protection filter textile materials, medical textile materials, agricultural textile materials, special decorative textiles, and high-performance reinforced composite materials will become the focus of all types of special support. By adopting a point-to-face approach, Drive the overall development of the industry. Some people predict that with the country's large-scale infrastructure construction and the deepening of energy-saving environmental protection projects, industrial textiles will become the star of the textile industry. The polypropylene industry will also use this Dongfeng to accelerate the development in the industrial field, mainly in the fields of nonwovens and engineering fibers. Polypropylene non-woven fabrics have the advantages of short process flow, high production efficiency and low processing cost. Therefore, non-woven fabrics made of polypropylene fiber have always occupied an important position. They are widely used in medical and health products, home decoration, packaging materials, and clothing accessories. . In addition, high-strength polypropylene has excellent mechanical properties and chemical resistance. With the emphasis on project quality, the application of high-strength polypropylene in roads, reservoirs, and dam construction will increase rapidly. In the future, the development of industrial textiles will see the further development of polypropylene fiber.
5 . Conclusion
At present, China's polypropylene fiber raw materials and product development is still relatively inadequate, which also hindered my development and application of polypropylene industry. In the future, the development of the polypropylene industry should focus on accelerating the adjustment of the industrial structure and improving the competitiveness of the industry; it should increase the development of new products, and actively introduce and absorb foreign advanced technology and equipment; intensify the development and production of special resins, development New products. We should give full play to the advantages of polypropylene, through the adoption of new processes and modified technologies to enhance the competitiveness of traditional polypropylene industry, the future prospects for the development of polypropylene will be very broad. In the future, polypropylene production enterprises must clearly define the direction of development, look for breakthroughs in development, seize opportunities, and promote the healthy development of China's polypropylene industry. After getting out of the financial crisis, the demand for polypropylene fibers will continue to rise in the coming years.
