Entering the “no man’s land”, China’s chemical fiber industry bravely explores new directions
Huawei President Ren Zhengfei’s words at this year’s National Science and Technology Innovation Conference are thought-provoking: “Huawei is gradually entering a no-man’s land in this industry. There are no established rules and no one to follow.” It is precisely because he believes that “major innovation is the law of survival in no man’s land” that Ren Zhengfei regrets, “Without theoretical breakthroughs, without technological breakthroughs, without a large amount of technological accumulation, it is impossible to create Explosive innovation. Huawei’s ‘opportunistic’ speed of following others will gradually slow down, and the responsibility of establishing a website to guide theory has come.”
The chemical fiber industry is also facing the same problem. Duan Xiaoping, vice president of the China Fabric Industry Federation and president of the China Chemical Fiber Industry Association, once said in an interview: “The chemical fiber industry seems to have entered a state of ‘no man’s land’ and has lost the objects to learn from. This kind of Under such circumstances, it is necessary for everyone to make progress together. As a major country in chemical fibers, China has the responsibility and obligation to take up the banner of R&D, invest in R&D, and promote the development of the chemical fiber industry.” China is a major country in chemical fibers, accounting for 70% of chemical fiber production. , is the only country with all varieties of chemical fibers, and the overall level of China’s chemical fibers has been greatly improved, especially in the conventional field, as well as in high-performance fibers and differential chemical fiber dimensions. China has taken the leading position. The current development focus of China’s chemical fiber represents the future direction of the chemical fiber industry.
Large varieties enter the era of low profits
High-value functionalization is the direction
In 2015, China’s chemical fiber output reached 48.31 million tons, and the proportion of chemical fiber in fabric fiber finishing increased from 70% in 2010 to 84.1%, which plays an important role in promoting the sustainable development of China’s economy. the supporting role. However, under the new normal, China’s chemical fibers are facing a period of overcapacity. According to relevant statistics, the growth rate of my country’s synthetic fiber production capacity slowed down to 4.5% in 2015, and the average annual growth rate of fiber finishing is estimated to be 2.8% to 3.0%. In particular, large varieties of general-purpose synthetic fibers have entered the era of “low profit”. The development of PET and PA fiber varieties is basically based on tracking and imitation, which has restricted the sustainable development of fabrics and related industries.
However, from the perspective of demand, the future increase in fiber will still need to rely on large varieties of general-purpose synthetic fibers. According to relevant data, the United Nations estimates that the population will be 7.76 billion in 2020, with a net increase of 410 million, and an average annual growth rate of 1.09%; between 2020 and 2030, there will be a net increase of 740 million people, with an average annual growth rate of 0.9%. As the population grows, fiber consumption will continue to grow accordingly. “By the end of the 13th Five-Year Plan, per capita fiber consumption will exceed 12.5 kilograms per person, an increase of 0.6 kilograms per person compared with 2015, and total fiber consumption will be close to 100 million tons. Among them, synthetic fibers will reflect the growth in demand for fabric fibers. The main force.” Luo Hongjing, deputy director of the Optimization Consulting Center of the China Petrochemical Corporation Economic and Technology Research Institute, analyzed.
Zhu Meifang, dean of the School of Materials Science and Engineering at Donghua University, also believes that in the future, polyester production capacity and demand will continue to account for about 88% of the total domestic synthetic fibers, while nylon production capacity and demand will increase. The speed reaches 9% and 12%, and the proportion of total synthetic fibers increases to about 6%.
So under the strong demand, how should the large variety of synthetic fibers in the era of meager profits develop? “The industry urgently needs to rely on large-capacity engineering foundations to promote the quality of conventional products, increase product added value, and realize high-quality multi-functional general fibers.” Zhu Meifang proposed that in the future, fiber components should progress from single-way lamination and simplicity to multi-layer construction. , Fiber function research should progress from passive adaptation to active innovative design, while strengthening basic research, injecting driving force into product research and development, supporting the development of original key technologies, and increasing the intersection and integration of multi-disciplinary technologies.
The good news is that the industry has already started relevant research. The collaborative innovation system for the solution-dyed fiber industry chain led by the China Institute of Textile Science and Industry, with close cooperation between industry, academia and research, will focus on polyester, polyamide fiber and regenerated cellulose fiber to break through the key core technologies in each link of the entire industry chain to help the industry. Achieve rapid and healthy progress.
The enterprise level is also constantly conducting innovative research and development and has achieved good results. Chen Fei, vice president of Fujian Jinjiang, said that currently, Jinjiang Technology has developed three high-quality nylon products, namely porous fine denier fiber, liquid dyed fiber and functional series fiber, relying on the company’s unique core technology, and the market feedback has been particularly good. “As society continues to advance, people’s materialAdded value; in terms of leading the market, new materials and new products should be provided, and customized products should be provided to meet the individual needs of customers.
At present, people-oriented science and technology, and the integration of humanities and science and technology have become the themes 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 integrate innovation and the culture of the times. The pursuit of fashion, trends, personality, taste and other social psychology are combined together, so that breakthrough products can be developed and directly impress consumers.
