Recently, the China Chemical Fiber Technology Conference, which is the leader of the future development of China's chemical fiber industry, was held in Lianyungang City, Jiangsu Province, including experts and scholars in the field of textile and chemical fiber, including the academicians of the Chinese Academy of Engineering Environment and Textile Engineering, Jiang Shicheng, Yu Jianyong and Zhang Quanxing. People agree that the green manufacturing of fiber materials should be an important task for the transformation and upgrading of the industry.

Fully promote green manufacturing in the chemical fiber industry, green transformation of stocks, and incremental green construction

"At present, the chemical fiber industry has entered the 'three-phase superposition stage' of supply and demand re-equilibration period, stock capacity optimization adjustment period and high-quality increment moderate development period. Under this period, the industry development mode is extensive, unbalanced and uncoordinated. The problem of unsustainableness is still outstanding. The ability of independent innovation is weak, the structural capacity of conventional chemical fiber is excessive, the proportion of high value-added products is low, the development of intelligent manufacturing and production service industry lags behind; the upstream and downstream development of the industrial chain is not balanced, and the raw materials are not matched. The resources and environmental constraints have become increasingly tight.” Academician Jiang Shicheng believes that green development is one of the important concepts of the “13th Five-Year Plan” for economic and social development. The development of the chemical fiber industry faces more stringent environmental laws and regulations and environmental governance. It is required to carry out green recycling and low-carbon transformation of stocks, and carry out green recycling and low-carbon construction for increments, so that its development is based on resource support, environmental capacity, and ecological protection, and improve green manufacturing.

He suggested that chemical fiber enterprises must more closely integrate the market development trend, take the initiative to grasp the core elements of technology, brand and ecology, develop green processing technology, and achieve low energy consumption, low emission, low pollution and high efficiency in the processing.

It is understood that the Ministry of Industry and Information Technology is fully promoting the green transformation of chemical fiber and other industries. In addition to the list of 99 green design pilot enterprises in two batches including light industry textiles, it also cooperates with the National Development and Reform Commission to establish a waterfront “leader”. The system organizes research on the “leaders” program rules for water efficiency in high water consumption industries.

Gao Ning, deputy director of the Department of Energy Conservation and Comprehensive Utilization of the Ministry of Industry and Information Technology, revealed that the Ministry of Industry and Information Technology will focus on the construction of new technologies for energy conservation and environmental protection, recycling and clean production systems in the chemical fiber industry.

Among them, the new technology promotes green pulping, polyester non-ruthenium catalyst polymerization, stock liquid coloring and on-line addition and other technical processes, the development of new solvent cellulose fiber and dyeable fiber and other green fiber products, and promote bio-based fiber The “green fiber” evaluation system for products such as fibers produced by raw materials, recycled fibers, and colored liquids for raw materials.

Supporting downstream users to use green fiber, the first batch of 8 chemical fiber companies have obtained green fiber certification

According to the development of the “Twelfth Five-Year” chemical fiber industry provided by the China Chemical Fiber Industry Association, during the “Twelfth Five-Year Plan” period, the Chinese chemical fiber industry has formed a complete industrial chain supporting system, which produces products from conventional chemical fiber and high-performance chemical fiber. To bio-based chemical fibers, the coverage and application range is also very wide. Among them, the green manufacturing technology represented by bio-based, recycled chemical fiber and raw material core technology has made great progress.

According to statistics, in 2015, the total production capacity of new bio-based fibers reached 400,000 tons, making full use of agricultural products, crop waste and resources such as bamboo, hemp and fast-growing forests to achieve renewable, degradable and cyclable.

"20 500ml waste beverage polyester bottles can be recycled to make a top coat. Two two-liter polyester bottles can be recycled to make a 0.09m2 carpet. 35 two-liter polyester bottles can be used to make a sleeping bag. All filled with fiber. 1 ton of waste polyester bottle can produce about 0.9 tons of recycled polyester fiber, which can save 6 tons of oil and reduce 3.2 tons of carbon dioxide emissions.” Former inspector of the Industry Coordination Department of the National Development and Reform Commission and vice president of China Chemical Fiber Industry Association He Yanli said that the annual global production of chemical fiber exceeds 40 million tons, of which over 90% comes from oil. With the increasingly tense oil resources and the global crisis as a global crisis, the search for alternative green fibers has become a new growth point for the chemical fiber industry. What is gratifying is that China's overall technical level in the two fields of bio-based and recycled chemical fiber has reached the international advanced level.

Duan Xiaoping, president of China Chemical Fiber Industry Association, revealed that the “13th Five-Year” chemical fiber industry has also listed green manufacturing technology as one of the top ten key scientific and technological development tasks, and specifically decomposed into 8 energy-saving and emission-reduction technologies + 3 green fiber manufacturing. Technology to tackle the problem. He also suggested that policy support should be strengthened in the construction of “green fiber” certification, clean production certification, and industry access certification to promote the application of green technologies.

He Yanli told reporters that chemical fiber as a raw material end of textile and other industries, if it does not achieve green manufacturing at the source, the green development of the whole industry cannot be discussed at all. She introduced that this year China Chemical Fiber Industry Association launched the “Green Fiber” logo certification, perfected the green certification system for fiber materials, and guided the green development of the industry.

He Yanli introduced that green fiber refers to chemical fiber that is derived from biomass and recyclable raw materials, low-carbon and environmentally friendly in the production process, and is environmentally friendly or recyclable after being discarded. , bio-based chemical fiber, raw liquid coloring chemical fiber.

“At present, many companies have applied for it, and the first batch of 8 chemical fiber companies have obtained the 'green fiber' certification.” He Yanli said that in order to promote the recognition and use of the “green fiber” mark, the association will open the certification of downstream enterprises. Application, that is, not limited to fiber manufacturing and processing enterprises, can be applied to yarns, fabrics, clothing, home textiles, industrial textiles and other fields, and documents will be released soon. She suggested that in the future green procurement of the government and the public sector, the “green fiber” certification will be included in the designated procurement list, which will force the green transformation of the whole industry.
