Interpretation Of The Theme Of The Seventeenth China International Chemical Fiber Conference: Innovation Driven &Nbsp; Green Low Carbon

The seventeenth China International Chemical fiber conference was held in Wujiang in September 1st. The meeting discussed in depth the new transformation of world chemical fiber and China's chemical fiber industry "12th Five-Year" development expectations. In order to fully understand the key points of development of China's chemical fiber industry during the "12th Five-Year" period, we have focused on the two themes of "innovation driven" and "green low carbon".

Theme 1 innovation drive the driving force of sustainable development

Key words: optimization structure, high performance fiber industrialization technology and equipment autonomy

Innovation driven has always been the driving force for the development of China's chemical fiber industry. The development history of the chemical fiber industry in the past sixty years is actually a history of innovation and development.

60 years of innovation History of development Push ahead

Looking back on the development process of 60 years, China's chemical fiber industry has gone from zero to the world's largest chemical fiber country. Every step has gone through the track of "innovation driven". Almost every major technological breakthrough has been accompanied by the rapid development of increments, providing a strong raw material guarantee for textile industry development needs.

After the founding of new China, we first restored the Anton chemical fiber factory and the Shanghai artificial silk factory. In the last century 50~60, we introduced viscose filament, nylon filament and Vigny nylon complete technology and equipment to build the Baoding chemical fiber factory, the Beijing synthetic fiber experimental plant and the Beijing Vigny nylon factory, and opened the prelude to the development of the new China chemical fiber industry. In the 60~70 era, on the basis of digestion and absorption of imported equipment and technology, the state built a batch of viscose enterprises such as Nanjing chemical fiber and Xinxiang chemical fiber and several ten thousand ton Vigny textile factories. Subsequently, the state has focused on the development of the synthetic fiber industry, and has built four large-scale chemical fiber enterprises in Shanghai Jinshan, Liaoyang, Tianjin and Sichuan Chuan Wei. In 80s, the complete set of large-scale, large-scale polyester, direct spinning polyester staple production technology was introduced, and Yizheng chemical fiber and Shanghai Jinshan two phases were constructed. So far, China has basically formed a relatively complete system of chemical fiber industry.

In 90s, the technological progress of the chemical fiber industry entered a period of rapid development. During this period, the rapid development of advanced technology and equipment in the world has effectively reduced the gap between China and the world, and laid a solid foundation for the independent innovation and rapid development of the new century.

After entering the new century, the technological progress of the industry is more. Accelerated obviously 。 Major breakthroughs have been made in the technology independence and equipment localization project of the complete set of technical equipment represented by large capacity (Nissan 300~1200 tons) polyester polyester, annual production of 45 thousand tons and above viscose staple fiber, daily production of 15~20 tons of continuous spandex, annual output of more than 1 million tons of PTA, and daily output of 150 tons and above nylon polymerization. The equipment has been rapidly promoted and applied, and has comprehensively promoted the level of technology and equipment and competitiveness of products in China's chemical fiber industry, promoted the rapid development of the chemical fiber industry, and made a significant contribution to the structural adjustment of the world's chemical fiber industry.

During the "11th Five-Year" period, the chemical fiber industry continued to promote technological progress and industrial upgrading, and strive to create an industry's capability of independent innovation. In the past five years, 21 major technological and invention achievements have been achieved. Among them, 1 were awarded the first prize of national science and technology progress, two were awarded two, and two were awarded 8 national technological inventions. The variety of chemical fiber products is more abundant, quality and added value have been continuously improved, and the international competitiveness of the industry has been significantly enhanced. In 2010, the overall differential rate of chemical fiber reached 46.5%, which was 15.5 percentage points higher than that in 2005. Carbon fiber, aramid fiber, ultra high molecular weight polyethylene, polyphenylene sulfide, Xuan Wuyan and other high performance fiber as the representative of the autonomous technology and industrial production has made certain breakthroughs, and has played a good exemplary role. The high performance fiber industry has begun to take shape, up to the top level, and can partly replace imports. It has already been able to meet the needs of aviation, aerospace and other fields.

Clear objectives and tasks of innovation

During the "12th Five-Year" period, China's chemical fiber industry is in a critical period of transformation and upgrading, and innovation drive must play a greater role. Only by relying on independent innovation can we continuously promote industrial upgrading in order to continuously create and enhance the overall competitiveness of the industry.

Development goals:

The upcoming "development plan for the 12th Five-Year" of the chemical fiber industry is just one. Independent innovation The planning is a planning of technological progress, with heavy emphasis on innovation driven, heavy weight, clear objectives and tasks. In the five major development goals of the industry, there are two clearly related to technological innovation:
The product structure is constantly optimized. The proportion of differentiated fiber varieties should be increased to meet the needs of differentiation and individuation. By 2015, the chemical fiber differential rate increased to more than 60%; the self-sufficiency ratio of chemical fiber for high-grade fabrics and products reached 85%; the proportion of industrial chemical fiber reached 29%; the main target of making up for the shortage of cotton was Gao Fangzhen and super simulation fiber, accounting for 15% of the total output of chemical fiber.

The capability of high performance fiber industrialization has improved significantly. Aramid 1313, ultra high molecular weight polyethylene, continuous basalt fiber and other products have reached the advanced level of the world. The industrial production and application of carbon fiber, polyphenylene sulfide, high strength high modulus polyvinyl alcohol fiber and other industrial products have achieved greater breakthroughs, and the product performance has reached the international level. The aramid fiber 1414, polyimide, polytetrafluoroethylene and other fibers have completed the development and production of pilot technology and achieved industrialized production. By 2015, the total production capacity of domestic high-performance fibers will be around 160 thousand tons. The development and application of serialization and differentiation will be focused on. The high performance fiber industry will reach the international advanced level.

Main tasks:

In the seven tasks of the "12th Five-Year development plan" of the chemical fiber industry, there are four key technical progress and independent innovation.
We will vigorously promote the quality of conventional products and enhance the added value of products. The large volume of chemical fiber products is of great significance to the transformation and upgrading of the industry. Its quality is mainly through the technological transformation of process equipment, the research and development of differentiated and functional fiber production technology, and the overall improvement of product quality and added value.

Efforts should be made to improve the industrialization level of high-performance fibers. High performance fibers and their materials are key materials related to national defense construction, economic development and supporting the development of high-tech industries. They are the material basis for promoting the development of all relevant technological innovation and upgrading of industries, and the new growth point to promote the development of strategic new industries in the new era. Their industrialization level is a concentrated expression of a country's high technology level. The focus of development in 12th Five-Year is to lay stress on innovative ability building and personnel training, build an innovation platform for production, teaching and research, continue to organize and implement special projects of industrialization, and accelerate the industrialization process.

Vigorously promote the development of biomass fiber and its raw materials. The development of biomass fiber and its raw materials has important strategic significance for the industry to reduce its dependence on oil resources, and to realize degradation, recycling, low carbon economy and so on. It has a more realistic and far-reaching significance for solving the problems of agriculture, rural areas and farmers, the two dimensional structure of urban and rural areas, and the pillar of the textile industry. The focus of development in 12th Five-Year is to make full use of crop waste and bamboo, linen, fast-growing forests and marine life resources to develop new biomass fiber materials, research and develop new technologies and equipment integration technologies for green processing of fiber materials, and achieve industrial production.

We should speed up the improvement of the autonomy and engineering level of key technologies and equipment. The autonomy and localization of complete sets of technology and equipment have been the driving force for the rapid development of the chemical fiber industry and the fundamental guarantee for the sustainable development of the future industry. The focus of the 12th Five-Year development is to strengthen integrated innovation, develop advanced and practical technology with independent intellectual property rights, improve the R & D capability and engineering capability of engineering companies, pay attention to the development and application of energy saving, high efficiency and environment-friendly chemical fiber and its raw material equipment, and speed up the industrialization of key technologies, supporting equipment and key components of differential fiber and hi-tech fiber.

At the same time, innovation driven should not only be reflected in the innovation and development of technology and complete sets of equipment, but also be reflected in the innovative development of the industry development mode and enterprise development mode. This is also an important part of the transformation and upgrading of the chemical fiber industry in the future, and it is also the fundamental guarantee for the sustainable development of the industry.

This innovation is to push the industry to gradually shift from a quantitative development oriented mode to a quality based and innovative driven development mode, and continuously build the core competitiveness of enterprises and industries for sustainable development. The development focus of 12th Five-Year is to promote the reorganization and integration of enterprises, improve industrial concentration, promote large-scale and intensive operation, create a large number of enterprises with strong international competitiveness, perfect standardized and modern enterprise management system, encourage superior enterprises to integrate upstream and downstream, strengthen enterprise basic management, and strive to build a number of chemical fiber brands with domestic and foreign market influence, and strive to upgrade the level of information technology in the industry.

The seventeenth China International Chemical fiber conference will closely focus on the theme of "innovation driven". Several sub forums set up by the conference will focus on technological progress and independent innovation. In particular, forums such as hi-tech fiber and advanced composite materials and industrial textiles are closely related to the emerging strategic industries encouraged by the current state. At the same time, every sub forum almost involves the content of downstream industries and technologies of chemical fiber, and the purpose is to promote the cooperative research and development and marketing of the upstream and downstream industry chain, and create a new mode of joint innovation and development of upstream and downstream enterprises.

　 Theme 2 green low carbon: the foundation of sustainable development

Keywords: biomass industry recycling economy

Green and low carbon is the main content of the development of the chemical fiber industry during the "12th Five-Year" period, and is also the foundation for sustainable development and future competitiveness of the industry.

Industry has achieved remarkable results

The work of energy conservation and emission reduction in the industry has achieved remarkable results. During the "11th Five-Year" period, the chemical fiber industry accelerated structural adjustment and industrial upgrading, eliminating a total of about 3000000 tons of backward production capacity. In 2010, the proportion of international advanced level of chemical fiber industry reached 70%, of which polyester polyester industry reached more than 75%, which provided a basic guarantee for energy conservation and emission reduction in the industry. Compared with 2005, the comprehensive energy consumption of chemical fiber ton decreased by 30.4% in 2010. The energy consumption level of polyester polymerization, viscose staple fiber, nylon polymerization and nylon filament has reached the international advanced level. The water intake of chemical fiber ton fiber has dropped by 25.7%, the discharge of waste water has dropped by 25%, the water reuse level of viscose industry has increased by 20 percentage points, and the water reuse rate of polyester industry has reached more than 95%.

At present, some key technologies for energy saving and emission reduction in the industry are being widely applied. For example, in recent years, the ring dryer has been widely used in the spinning of polyester superfine fiber projects. Its air volume is only 30% of the side blowing device, and the energy saving effect is remarkable. The new spinning heat medium circulation heating system can save energy by 15%. Activated carbon adsorption technology for viscose fiber production, the initial adsorption rate of 85%~89%, spinning production of CS2 and H2S exhaust gas removal rate can reach 95%, 99.5%, has been widely used in the industry.

The circular economy of the industry has developed well, and the regenerated polyester fiber industry has already formed a scale. In the past ten years, the chemical fiber industry has actively promoted the development of circular economy, and the scale of recycling economy, which is mainly recycled from waste polyester, has increased rapidly, and the level of technological products has been continuously improving. By the end of 2010, China's regenerated polyester fiber had an annual capacity of about 6000000 tons, and its actual output has reached nearly 4 million tons, accounting for 80% of the world's total output. It has become the largest producer of regenerated polyester fibers.

In other areas, the "11th Five-Year" industry has also made significant progress. First, the recovery and utilization of other fibers such as nylon and polypropylene have made great progress. The quantity of reuse has increased year by year, and the level of technology has been continuously improved. The application of recycled fiber has covered most of the downstream areas. The two is the recycling of raw materials and accessories, such as acetaldehyde recovery in large-scale PET plant, CPL recovery technology in large-scale nylon polymerization plant, and so on. The recovery rate can reach 99.5% and 100% respectively. Three, the dyeing and spinning technology of chemical fiber raw materials has been widely applied, and now has an annual capacity of 1 million 500 thousand tons. Compared with traditional dyeing technology, the technology can reduce more than 70% of CO2 exhaust gas, and tons of fiber can save 140 tons of dyed water.

Great progress has been made in the comprehensive utilization of resources. The annual production capacity of viscose fiber in China is about 2000000 tons, and cotton short lint is about 800 thousand tons per year, of which domestic cotton lint is about 600 thousand tons, so that the value of cotton lint has been fully utilized.

Significant progress has been made in the development of biomass fiber and its raw materials. The production technology of poly (terephthalate) (PTT) fiber, polylactic acid (PLA) fiber, polyhydroxyfatty acid ester (PHB/PHBV) fiber and poly (succinic acid) Ding Erzhi (PBS) fiber has made breakthroughs. Some varieties have formed industrial scale, such as PLA fiber has achieved 1000 tons of industrial production.

In terms of biomass raw materials, 1,3 propanediol (PDO), ethylene glycol (MEG) and 1,4 butanediol (BDO) have made major breakthroughs in the process of industrialization. Biotechnological polyols have been large-scale and industrialized in Changchun Dacheng and Fengyuan biochemical industries, and have been applied in the market.

Define future goals and tasks

Although the chemical fiber industry has made great achievements in the recycling economy, the situation facing the future development is still very grim. In the "development plan of 12th Five-Year" formulated by the state in the chemical fiber industry, the main objectives and tasks for the development of circular economy in the future are clearly put forward.

Development goals:

We should speed up the research and development of biomass renewable and biodegradable materials, actively promote cleaner production, strengthen the comprehensive utilization of resources, and establish a recycling economy development mode of chemical fiber industry. By 2015, compared with 2010, the energy consumption of the 10000 yuan industrial added value was reduced by 15%, water consumption was reduced by 20%, the discharge of tons of fiber wastewater was reduced by 10%, the emission of waste gas was reduced by 10%, and the recycling scale of waste polyester products, chemical fiber fabrics and garments reached 7 million tons.

In 2015, the energy contract management coverage of chemical fiber industry will exceed 20%, and the coverage of cleaner production audit in the industry will exceed 30%.

Main tasks:

We will promote energy saving, emission reduction and circular economy development and accelerate industrial transformation and upgrading. Strengthen the technology and Economic Research of "low carbon economy" in the industry. We will accelerate the industrialization of R & D and promotion of new technologies and equipment for energy conservation and emission reduction, and promote the application of cotton pulp black liquor treatment technology, waste bottle flake cleaning wastewater reuse and viscose waste water, waste gas treatment, recovery engineering and technology. We should strengthen the transformation from terminal management to process monitoring and clean production technology, and promote cleaner production of viscose and recycled fiber. Timely admittance conditions for viscose fiber industry. We should speed up the elimination of backward production processes and equipment such as high energy consumption and high pollution. We should actively promote the work of energy contract management, cleaner production audit and enterprise carbon footprint certification.

We should vigorously promote the recycling of resources, encourage and standardize the development of the fiber industry, and focus on strengthening the integration, upgrading and popularization of recycling technologies, products and complete sets of equipment such as waste polyester, waste silk and waste chemical fiber products. The organization has formulated circular economy development plan and technical roadmap for recycling and recycling textile products, and promoted the industrialization of chemical fiber, especially pure polyester fabric and clothing recycling technology. Guide social green consumption.

Actively promote the development of biomass fiber and biochemical raw materials. The biological industry is one of the strategic emerging industries that the country focuses on. Developing biomass resources instead of traditional chemical fiber materials is the main direction for the industry in 12th Five-Year and for a long time to come. We should increase policy support, R & D and capital investment, make more efforts to promote development, and make full use of resources such as agricultural products, crop waste and bamboo and fast-growing forests to achieve the industrialization of biodegradable, renewable biomass fiber, raw materials and comprehensive development and utilization. By 2015, the new solvent method has achieved the industrial production of 10000 tons of cellulose fiber, the biomass synthetic fiber has developed to 210 thousand tons of capacity, and the biomass based chemical fiber raw material capacity has developed to 300 thousand tons.
