China's polypropylene industry status and prospects

China Chemical Fiber Industry Association Polypropylene Professional Committee

1 . Foreword

Polypropylene is the youngest member of the four major synthetic fibers. Due to its low density, low melting point, high strength, acid and alkali resistance, polypropylene is widely used in clothing, decoration and industry.

The development of the future chemical fiber industry has already turned to a higher level of development after meeting the basic needs of the original chemical fiber as clothing, such as high-performance fiber for industrial use and high-comfort fiber for clothing. Regarding the current varieties of chemical fiber, in terms of production cost, production technology and environmental and ecological requirements that are increasingly valued today, polypropylene is undoubtedly a successful development. Compared with polyester, nylon and acrylic fiber, polypropylene has the advantages of low comprehensive energy consumption, low cost and no pollution due to single raw material, short process route and simple spinning process. Under the current situation of “energy saving and emission reduction”, The polypropylene industry will usher in a good development opportunity.

2 . China's polypropylene industry status

In the past few years, the application of new technologies and new technologies and the continuous development of new products have made polypropylene play an increasingly important role in the application of textile industry. Polypropylene and its fibers have quickly entered the new product market and are very good. Consolidate the status of the end use. The trend of polypropylene fiber consumption is mainly reflected in the sharp increase in demand for flexible semi-finished bulk container bags, health care products, agricultural textiles and automotive materials; carpets, geotextiles and construction textiles, clothing, medical and rope products The rising trend; especially the development of fine denier and functionalized fibers, has expanded its use in the field of application. In the field of material substitutes and new applications, the rapid development of non-woven products has remained unprecedented, especially in the application of health care products. As the demand for disposable products increases, polypropylene fibers will further increase. The development of new polypropylene fiber technology will make the variety more and more new.

On the other hand, with the continuous development of raw material polypropylene production technology, it will also provide polypropylene with more choices of raw materials. At present, the world's major polypropylene companies are committed to the research and development of new production processes and new catalysts in order to improve the competitiveness of products in the market. In recent years, domestic polypropylene companies have also achieved remarkable results in the development and production of new products. For example, Jiujiang Petrochemical Company's transparent polypropylene special materials can replace similar imported products, and the transparency and heat resistance of the products have reached the domestic advanced level of similar products. Its radiation resistance has broken the traditional domestic UV and electromagnetic radiation, reaching the domestic leading level. At the same time, the innovation of processing and modification technology has also created conditions for the upgrading of polypropylene products, which further strengthens the development of polypropylene-polypropylene, which is a vigorous industrial chain, and makes 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 is more outward than other chemical fiber varieties. Not high, the direct impact of the financial crisis is still relatively small, but the impact of the slowdown in the growth of the downstream textile industry on the weakening of polypropylene demand still exists, and some enterprises have stopped production and reduced production. According to the statistics of the National Bureau of Statistics, the national polypropylene production in 2008 was 266,400 tons. However, it is understood that this figure is obviously too small. According to incomplete statistics, China's polypropylene fiber production capacity was about 580,000 tons in 2008 . Products include filament, staple fiber, industrial yarn, BCF , tobacco tow, etc., of which polypropylene filament is the main, accounting for about 43% . The production capacity of the main filament enterprises is shown in the table below.

3 . China's leading polypropylene industry

Fujian Sanhong Renewable Resources Technology Co., Ltd. is a wholly foreign-owned enterprise specializing in the production of polypropylene fiber, integrating scientific research, production and operation. The company's recycling resources recycling technology has passed years of experience accumulation and technology precipitation, its technical level and annual output ranks in the forefront of the industry, is the country's largest renewable resources polypropylene filament export production enterprises, but also the Fujian Province cycle Economic enterprise. In 2008 , the total output of polypropylene fiber was 20,000 tons. In 2009 , the company expanded its production scale and increased the investment in equipment and technology. The total output of polypropylene fiber is expected to reach 23,000 tons. Comprehensive analysis of the production strength and production scale of the national polypropylene industry, Sanhong is the largest manufacturer in the domestic polypropylene filament industry, and its production equipment is also the most advanced one-step spinning production equipment in China.

4 . China's polypropylene industry development trend

With the introduction of the "Textile Industry Adjustment and Revitalization Plan", with an unprecedented attention, a new round of development of industrial textiles will be opened. In the next three years, geotextile materials, environmentally-friendly filtration textile materials, medical and textile materials, agricultural textile materials, special decorative textiles, and high-performance reinforced composite materials will become the focus of various special support, through a point-by-point approach. Drive the overall development of the industry. It has been predicted that with the deepening of the country's large-scale infrastructure construction and the deepening of energy conservation and environmental protection projects, industrial textiles will become the star of the textile industry. The polypropylene industry will also take this opportunity to accelerate the development of the industrial sector, mainly in the field of nonwovens and engineering fibers. Polypropylene non-woven fabrics have the advantages of short process, high production efficiency and low processing cost. Therefore, non-woven fabrics made of polypropylene have always occupied an important position, and are widely used in medical and health products, home decoration, packaging materials, clothing accessories, etc. . In addition, high-strength polypropylene has excellent mechanical properties and chemical resistance. With the emphasis on engineering quality, the application of high-strength polypropylene in roads, reservoirs and dam construction will increase rapidly. Under the tone of vigorously developing industrial textiles in the future, polypropylene fiber will further develop rapidly.

5 . Conclusion

At present, China's polypropylene fiber raw materials and product development is still relatively insufficient, which also hinders my development and application of polypropylene industry. In the future, the development of the polypropylene industry should focus on accelerating industrial restructuring and improving the competitiveness of the industry; it should increase the development of new products, actively introduce and absorb foreign advanced technology and equipment; increase efforts to develop and produce special resins, and develop New product. We should give full play to the advantages of polypropylene. By adopting new technologies and modification technologies to enhance the competitiveness of the traditional polypropylene industry, the future development prospects of polypropylene will be very broad. In the future, polypropylene production enterprises must clearly define the development direction, find breakthroughs in development, seize opportunities, and promote the healthy development of China's polypropylene industry. After getting rid of the impact of the financial crisis, the demand for polypropylene fiber will continue to rise in the next few years.
