Huawei CEO Ren Zhengfei in this year's General Assembly on scientific and technological innovation passage, thought-provoking:. "Huawei is the industry gradually scored no man's land, at no pilot, no established rules, no follow plight" It is because It is recognized that "major innovation is the survival rule of no-man's land", Ren Zhengfei regrets that "there is no theoretical breakthrough, no technological breakthrough, no large amount of technology accumulation, it is impossible to produce explosive innovation. Huawei follows the 'opportunism' of people running high Speed ​​will gradually slow down, and the responsibility to create guiding theory has arrived."
The chemical fiber industry is also facing the same problem. Vice president of China Textile Industry Association, China Chemical Fiber Industry Association president end Xiaoping once said in an interview: "chemical fiber industry seems to have entered a state of 'no man's land', loss of learning objects, this situation Under the circumstance, the whole world needs to be developed together. As a chemical fiber country, China has the responsibility and obligation to set off the R&D banner and invest in R&D to promote the development of the global fiber industry.†China is the world's chemical fiber country, accounting for 70% of global fiber production. It is the only country with all chemical fiber varieties, and the overall level of China's chemical fiber has been greatly improved, especially in the conventional field, as well as high-performance fiber and differential fiber, China has taken the lead. The current development focus of China's chemical fiber represents the future direction of the global fiber industry.
Large varieties enter the era of low profit
High value functionalization is the direction
In 2015, China's chemical fiber production reached 48.31 million tons, and the proportion of chemical fiber in textile fiber processing increased from 70% in 2010 to 84.1%, which played an important supporting role in promoting the sustainable development of China's economy. However, China's chemical fiber under the new normal is facing overcapacity stage state. According to relevant statistics, the growth rate of China's synthetic fiber production capacity slowed to 4.5% in 2015, and the global fiber processing volume is expected to grow at an average annual rate of 2.8% to 3.0%. In particular, large-scale synthetic fibers have entered the era of “micro-profitâ€. The development of PET and PA fiber varieties is mainly based on tracking and imitation, which restricts the sustainable development of textile and related industries.
However, from the perspective of demand, the future increase in fiber still depends on a large variety of general synthetic fibers. According to relevant data, the United Nations is expected to have a global population of 7.76 billion in 2020, a net increase of 410 million, an average annual increase of 1.09%; a net increase of 740 million people between 2020 and 2030, an average annual increase of 0.9%. As the population grows, fiber consumption will continue to grow accordingly. “At the end of the “ Thirteenth Five-Year Planâ€, the global per capita fiber consumption will exceed 12.5 kg/person, which is 0.6 kg/person higher than that in 2015. The total global fiber consumption will be close to 100 million tons. Among them, synthetic fiber will reflect the demand of textile fiber. The main force of growth.†Luo Hongjing, deputy director of the Optimization Consulting Center of the Economic and Technical Research Institute of China Petrochemical Corporation.
Dean of the Faculty of Materials Science and Engineering, Donghua University, Zhu Meifang also believes that the future demand for polyester production capacity and the proportion of the total domestic synthetic fiber will continue to remain at around 88%, nylon production capacity and demand growth of 9% and 12%, The proportion of total fiber is increased to about 6%.
Then, under the strong demand, how should the large variety of synthetic fibers in the era of meager profit develop? “The industry urgently needs to rely on the large-capacity engineering foundation to promote the high quality of conventional products, enhance the added value of products, and realize the high-quality and multi-functionalization of general-purpose fibers.†Zhu Meifang proposed that in the future, fiber components should be developed from single-composite to simple-to-multiple reconstruction. Fiber function research should be developed from passive adaptation to active innovation design, while strengthening basic research, injecting the driving force for product research and development, supporting the development of original key technologies, and increasing the intersection and integration of multidisciplinary technologies.
Fortunately, the industry has already started relevant research. The collaborative innovation system of the raw liquid coloring fiber industry chain, which is closely coordinated by the China Academy of Textile Science, will focus on polyester fiber, polyamide fiber and regenerated cellulose fiber, and break through the key core technologies of all links in the entire industry chain. Help the industry achieve rapid and healthy development.
At the enterprise level, innovation and research and development are also constantly underway and have achieved good results. Chen Fei, vice president of Fujian Jinjiang Technology Co., Ltd., said that at present, Jinjiang Technology has developed three high-quality nylon products, such as porous fine fiber, raw liquid coloring fiber and functional series fiber, based on the company's unique core technology. The market feedback effect is very good. . "As the society continues to develop, people's material living needs are constantly improving. In the future, the development of nylon fiber is bound to develop in the direction of functionalization and high-end." Chen Fei said that in the future, Jinjiang Technology will develop fast-heating nylon fiber. High-end products such as high-strength nylon fiber and conductive nylon fiber.
He Zhuosheng, president of the China Chemical Fiber Industry Association's nylon branch and deputy general manager of Guangdong Xinhui Meida Nylon Co., Ltd., also pointed out that the current production process of nylon's main raw material caprolactam has made breakthroughs, and the large-capacity nylon 6 polymerization device and process have been further improved. spinning and integration of domestic equipment is also imported equipment, future, nylon should further optimize the product structure. He analyzed that compared with developed countries, China's industrial plastics and industrial yarns have a low proportion, and there is still much room for optimization in the variety structure. Moreover, under the influence of the improvement of national income and the change of consumption concept, fiber and decorative fiber for automobile industry. The development potential is large.
High-performance fiber has unlimited potential
High efficiency and low cost are the development priorities
Carbon fiber and other high performance fibers are aviation, aerospace, national defense, economic construction and scientific and technological progress and other essential major strategic materials, low-carbon economy is one of the lightweight core technology. In recent years, driven by relevant national policies, China's carbon fiber industry has developed rapidly, process technology has been continuously optimized, production equipment has been continuously improved, and application fields have been continuously expanded, successfully solving the problem of “from scratchâ€.
Relevant data show that the total amount of global PAN-based carbon fiber in 2015 was about 60,000 tons, and the aviation, industrial and sports/leisure industries accounted for 22%, 62% and 16% respectively. Some experts predict that by 2020, carbon fiber demand will reach 100,000 tons, of which 72% will be used in the automotive industry and wind power industry. “Although the carbon fiber industry is facing huge opportunities, the high production cost is one of the bottlenecks that hinder the development of its industry,†said Luo Yifeng, director of the National Special Synthetic Fiber Information Center.
At present, the international and domestic carbon fiber research departments are constantly striving to develop low-cost technologies. The US Oak Park National Laboratory began researching and preparing low-cost carbon fiber in 2001. In 2016, it issued a technology license. Its "large-wound acrylic fiber + microwave plasma carbonization" technology can reduce the cost by 50%; Japan's "PAN aromatic cyclization + microwave plasma" "Carbonization" technology can increase production efficiency by 10 times; the University of Tokyo and Japan Industrial Technology Research Institute, Toray, Teijin, Toho Texex (Teijin Group), Mitsubishi Rayon have jointly developed a new carbon fiber manufacturing Technology can reduce energy and carbon dioxide emissions necessary to make carbon fiber by about half.
Domestically, Donghua University's "PAN aromatic cyclization + melt or dry spray wet spinning + rapid oxidation" technology has obtained 2 US invention patents, 5 Japanese invention patents, and 3 Chinese invention patents. Currently, the technology is in the pilot stage. Carbon Fiber Research Center of Shandong University are also joint military production units, fiber and composite materials manufacturer, the production of carbon fiber research low-cost large-scale expansion in terms of preparation technology, application technology, recycling technology.
It can be seen that the research and development and industrialization of carbon fiber and carbon fiber composite materials have entered a period of major innovation, and in the next 5 to 10 years, it will usher in the heyday of great development. At the same time, with the continuous decline in production costs and the development of low-cost recycling technology, its market applications will gradually become more popular and become a new type of bulk products.
Under the new industrial revolution
Green and smart become the main trend
The world today is in the midst of a new technological revolution characterized by the Internet, new energy, new materials , biotechnology, and green, smart and sustainable, and the third industrial revolution, globalization, digital, intelligent , green, and fine. The relationship between technological innovation and corporate economic development is more direct and close than ever before. Throughout the evolution of advanced manufacturing technologies, “green†and “smart†will become the main development trend. This has a profound impact on the industrial form, production methods and business models of the chemical fiber industry.
At present, the chemical fiber industry is making efforts to promote green design, green materials, green manufacturing and recycling development. In March of this year, the “green fiber†LOGO logo was released, and 8 companies have obtained “green fiber†certification. End Xiaoping stressed that "green fiber" Certification is not an appraisal, but rather advanced, green, safe, environmentally friendly products one finds.
Jiangsu Shenghong Technology Co., Ltd. is one of the companies that have obtained the “green fiber†certification. The company’s chief engineer, Mei Feng, said that Shenghong is committed to independent innovation and vigorously promotes scientific and technological innovation projects, and has overcome the key links of bio-based PTT fibers. Technical difficulties, the formation of PDO raw material production, PTT polymerization, PTT spinning, PTT fabric printing and dyeing technology industrialization one-stop. Recently, Shenghong's “60,000 tons of melt direct spinning bio-based PTT differential fiber project†officially laid the foundation, further consolidating the advantages of enterprises in the bio-based PTT fiber industry.
In recent years, viscose fiber industry through the use of new practical technology, have a greater degree of improvement in terms of energy saving, waste management and other industries. However, with the high cost of environmental governance, the environmental protection pressure of the viscose fiber industry is increasing. Tian Ke, Secretary-General of the Cellulose Fiber Branch of China Chemical Fiber Industry Association, pointed out that during the “13th Five-Year Plan†period, the industry will focus on promoting green pulping engineering technology, adopting new technology to upgrade pulping enterprises, adopting paper-based pulping technology and straw. Comprehensive utilization of technology to achieve effective use of resources. At the same time, it is encouraged to build a stable and sustainable bamboo pulp and hemp pulp base to develop efficient, environmentally friendly and low-cost clean pulping technology and equipment.
Gong Zai, an associate professor at the Beijing Institute of Fashion Technology, believes that under the new environmental protection situation, the viscose fiber industry needs to change its environmental protection concept. The environmental protection standard is only the bottom line, and the core and purpose is to improve the environmental quality . "The future development of the industry should seek technological breakthroughs from the source reduction, process control and end-of-pipe governance." Gong said.
Intelligent Manufacturing is also one of the industry's development direction. Du Rabbit, general manager of Beijing Uda Phase Change Energy Storage Technology Co., Ltd. introduced that the company has developed a phase change material that can adjust the temperature in both directions and implant it into the fiber to finally make the clothes "know and know the heat." “At present, this high-tech has achieved breakthroughs in fibers such as viscose, polypropylene and acrylic. In all functional wear, the intelligent two-way temperature adjustment wears a two-way temperature adjustment function, which is a technical product that can both heat up and cool down. This product revolutionized the traditional impression that textiles can only be kept warm or single cool." Du Tuoping introduced.
Improve the industry's "intellectual education" factor
Fashion branding into personalized labels
If “technology†is the “intellectual education†course that must be experienced in the transformation and upgrading, then “fashion†is the “beauty education†class that must be completed to enhance cultural self-confidence. The characteristics and connotations of fashion are one of the concentrated expressions and commanding heights of China's textile industry in the future for international competitiveness. Future textile and apparel industry to gradually stripping "low-profit industry, sweat economic, labor-intensive, low value-added manufacturing," the impression that these traditional labels, realize its "industrial relocation." The fashion industry must become a personalized label for the future development of the textile and garment industry; the fashion economy will inevitably become an industry business card that adds the charm of the times, and is also destined to become a necessary channel for enhancing the status, attention and voice of the industry.
As early as 2012, the chemical fiber industry has embarked on the fashion line, launching the “China Fiber Fashion Trend â€, showing the leading role and important influence of fiber on clothing, fashion, and the innovative power from textile sources. Through the research and release of China's fiber fashion trend strategy, China's chemical fiber enterprises have increased their efforts in differentiated and high-added product development, and their R&D investment has been continuously improved. The average R&D investment ratio of enterprises has increased from 2.5% in 2011 to 3.8% in 2015. . In the past five years, the influence and brand value of the participating companies represented by Shenghong Group have continued to increase in the downstream customers, achieving both fame and fortune.
Fashion is inseparable from the support of creative design. China’s famous fashion designer Wu Xuekai said that China’s chemical fiber industry is already strong, but in this era of subversion of Apple’s replacement of Nokia and digital replacement of Kodak, China’s chemical fiber needs to combine the power of technology with the power of fashion and communication to make innovation more Market value.
With the increasing diversification of consumer demand for products, flexible manufacturing has become one of the future development directions of the industry. Research Institute of Donghua University Hua-ping pointed out that the future of the industry in improving product development capabilities, should establish an online system to add, scale and differentiation to break the bottleneck, improve new product development efficiency and improve profitability levels; in reducing energy consumption On the other hand, it is necessary to establish a large-quality online quality control system for processes, equipment, raw materials, etc., to improve the quality management level of enterprises and reduce energy consumption of enterprises; in terms of improving quality, we should establish a process intelligent design and process simulation optimization system to improve differentiated functional newness. Variety quality, increase product added value; in leading the market, should provide new materials and new products, provide customized products to meet the individual needs of customers.
At present, technology-oriented people-oriented, humanities and technology integration has become the theme of the post-industrial era. Consumers are paying more and more attention to the cultural taste and artistry of products. Chemical fiber application products must also pursue fashion, trend, individuality and taste in innovation and era culture. When social psychology is combined, it is possible to develop breakthrough products that directly impress consumers.
