5 Years Of Assault And Pledge To Build A Strong Power Of Chemical Fiber

Careful observation will find that in the seventeenth China International chemical fiber At the meeting, the voice of China's chemical fiber industry was stronger than ever and attracted more attention from the world than ever before. This is not only because China's chemical fiber production has accounted for more than 60% of the world's total chemical fiber output, but also because this chemical fiber country has entered the full realization. Chemical fiber power The 5 year critical stage. "Transformation and upgrading, green and low carbon, innovation driven, harmonious development", each noun behind it contains systematic arduous projects.

　 Seize the new growth pole of industry

There is no doubt that the development of industrial textiles has become a measure of structural adjustment in the textile industry. Industrial upgrading One of the important signs of enhancing core competitiveness is to develop the new growth pole of modern textile industry. And the chemical fiber industry, which is responsible for the supply of raw materials for industrial textiles, is ushering in new opportunities for development. According to UN forecasts, the global textile fiber processing capacity will reach 2.53 billion tons in 2050, including 170 million 500 thousand tons of industrial textiles and 18.53 kilograms per person per year, accounting for 67.4%.

In 2010, the processing volume of China's industrial textiles reached 8 million 217 thousand tons, an increase of 13.6% over the same period last year, and the processing capacity of nonwoven fabrics reached 2 million 795 thousand tons, up 16% over the same period last year. In 12th Five-Year, the proportion of textile fiber processing to total textile processing will increase to 25% by 2015.

Industrial use in China Textile industry Li Lingshen, President of the association, believes that four factors promote the rapid development of industrial textiles: first, the use of industrial textiles instead of traditional materials to achieve higher functions and benefits; the two is the rapid development of high-tech fiber and manufacturing technology; three, the structural adjustment and upgrading of the textile industry, and the use of industrial textiles as a new growth point; four, the continuous expansion of market demand and the expansion of the application field of industrial textiles, which has led to the development of the industry and has attracted more attention.

Unlike terminal products such as clothing and home textiles, industrial textiles are not final products, and their end users are widely distributed in aerospace, energy, transportation, transportation, medical and health fields. Therefore, the idea of developing industrial textiles and fibers is very different from traditional textile products.

Yao Mu, academician of the Chinese Academy of engineering, summed up the experience and lessons of the domestic development of the industrial textiles industry for many years, and pointed out that industrial textiles need a variety of raw materials and a variety of technology combinations. Therefore, the development of final products must be combined with "government, production, learning, research and utilization". Under the leadership of the government, the textile and chemical fiber units should be willing to play a supporting role. The relevant organs and units of the end users should be pushed to the leading position and jointly developed to serve the latter process, forming a complete industrial chain and the final product market. He also reminded that because of the different uses and different conditions of the industrial textiles, the performance requirements vary widely. Some of the requirements are particularly harsh, and many aspects of the design work need to be further studied.

The development of industrial textiles is not only the most important part of China's textile industry, but also the trend of the world's chemical fiber industry. Li Changyu, Secretary General of the Korea Chemical Fiber Industry Association, said that South Korea encourages the "win-win" cooperation between the textile industry chain and other related industries, and promotes the chemical fiber industry and the "6T" technology -- Information Technology (IT), biotechnology (BT), nanotechnology (NT), environmental protection Technology (ET), space technology (ST), Cultural Technology (CT) - the organic combination of industries, expanding the scope of application of chemical fiber products, and creating new market demand points.

Taking the road of circular economy with Chinese characteristics

While developing industrial textiles will continue to expand applications and create markets, energy and resource depletion must also be dealt with. Based on many years of exploration and in-depth study, China's chemical fiber industry has established a recycling economy development path with Chinese characteristics and will continue to push forward in 12th Five-Year.

Yu Muhuo, vice president of the Research Institute of Donghua University, pointed out at the meeting that mankind has built up a huge petroleum technology and economic system in about 50 years. It is only a matter of time to establish a biomass technology economic system. Indeed, the development of biomass renewable and degradable fiber materials has become a global consensus. At present, domestic enterprises have made new progress in using straw to produce polyols.

In contrast, recycling and reuse of waste polyester and textiles are more Chinese characteristics. At present, the attention of other countries to recycled chemical fiber is not as good as that of China. Even Japan, which possesses the most advanced regenerative technology, has lost the momentum of further development due to its size and economic benefits, and the related technologies have not been applied in large scale in China and transferred to other countries. At this session, the Japanese Imperial company passed several forums to show its willingness to transfer technology to China and continue to develop the Chinese market.

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. The large-scale production of related products has largely replaced the original products, effectively alleviating the contradiction between the serious shortage of oil resources in China. 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. China has become the largest producer of regenerated polyester fibers.

Although the chemical fiber industry has made great achievements in the recycling economy, the situation facing the future development is still very grim. The grade of regenerated products with waste polyester as raw material needs to be improved. The recovery of textile fabrics and garments is limited by technology and other factors, and has not yet been effectively launched.

During the "12th Five-Year" period, the industry will 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. The chemical fiber industry will gradually establish a recycling economy development mode during the "12th Five-Year" period. By 2015, the recycling scale of waste polyester products, chemical fiber fabrics and garments will reach 7 million tons. The application of recycled bottle flakes on high-end products, the recovery of waste textiles and garments, the development and utilization of renewable, biodegradable biomass fibers and their raw materials are the focus of recycling industry in the next 5 years. In addition, the level of cleaner production and comprehensive utilization of resources will be further improved.

　 Let quality and cheap products create the market.

With the development of the society and the progress of the industry, the consumption concept is also changing. The development of chemical fiber industry should also be adjusted along with these changes.

Dr. Chen Jinlai, a representative of Taiwan Textile Development Association, has found that high-quality and cheap textiles are increasingly needed by consumers. He believes that the reasons for this trend are: WAL-MART, Japan UNIQLO, and Europe's H&M, Zara and other large scale department stores and chain stores have caused a low price trend, so that consumers are inclined to buy products of high quality and low price. Two, the low price competition has been aggravated by the global financial crisis. Three, electronic information and communication products have caused crowding out, and consumers will use their income to purchase electronic products such as iPhone, thus reducing the consumption of textile and clothing. At present, functional textiles with waterproof, breathable, moisture absorption, quick drying, antibacterial, odorant and UV resistant are favored. The premise of large-scale application of functional textiles is high quality and low price.

Similarly, high-performance fibers with high technology content and large capital investment need to reduce costs, improve performance and expand applications with the progress of technology and equipment. Shi Meiwu, senior engineer of the Quartermaster Equipment Research Institute of the General Logistics Department, has proved this point through the flame retardant fiber status.

Shi Meiwu pointed out that at present, flame retardant fibers have not been widely applied at home and abroad. The main reason is the lack of products with high performance and low price. For example, the fibers with high performance and intrinsic flame retardant are expensive and have poor dyeing properties. The coloring fibers of the raw liquor are more expensive and less adaptable, and the handle is poor. The flame retardant fibers with general properties are low in strength, large in smoke and even poisonous, poor in dimensional stability, poor in spinnability, and hot melt fibers such as flame retardant polyester, nylon, and so on, which can not be used for clothing. Among the many flame retardant fiber varieties, the development of polyaryl two azole fiber (PDO) is an important reason because of its cost advantages: raw materials are conventional industrial products, the technology is mature, the price is relatively low, and the source is wide; the polymerization process is short, the production facilities are few, no special equipment and technology are needed, the spinning process is relatively simple, the solvent can be recycled or used in other industrial production. However, Russia has been able to produce a similar structure of OXALON in Russia only in small quantities abroad. There is only a similar report on the development of insulating paper between POD centrifugal spinning and polyester in China.

High strength and high modulus polyethylene fibers can be described as the most mature varieties of high performance fibers in China, but still face the bottleneck of expanding application. Guo Zixian, chairman of Jiangsu Shen Tai Technology Co. Ltd., pointed out that the main factor restricting its expansion and upgrading is the high cost of fiber production. In recent decades, Shen Tai technology has been making great efforts to improve its fiber properties and reduce its comprehensive cost, and has achieved some results. According to statistics from relevant departments, the annual demand for UHMWPE fiber in China is more than 6000 tons. The UHMWPE fiber in China can meet the annual output of more than 3000 tons in the export and domestic high-end application market. If we can continuously improve our products, we can not only replace imports, but also export foreign exchange.

The international conference, held in the year 12th Five-Year, will not only make the world more aware of the development of China's chemical fiber industry, but also make China's chemical fiber industry more clearly aware of its responsibilities. China's chemical fiber industry will continue to move towards a strong chemical fiber industry along the road of sustainable development.
