Recycling And Reuse Of Chemical Fiber Industry Is Promising

From waste textiles, polyester bottles to high quality chemical fibers, recycled fiber recycling industry has become a sustainable green development industry with "turning waste into treasure".

Although there are still a few people who have misunderstood this industry, with the deepening of the concept of sustainable development, many people have turned their attention to this industry. With practical actions, it has proved that recycling fiber industry has green, circular and sustainable characteristics, which is in line with the trend of textile development in the new era.

At present, adhering to green development, comprehensively saving resources, increasing the comprehensive utilization of renewable resources, and insisting on green, low carbon and recycling development have become the consensus of society. The recycling of chemical fiber industry is shouldering greater social responsibility.

Recently, the 2018 annual meeting of China Chemical Fiber Industry Association regenerated chemical fiber Specialized Committee and the high quality development forum of recycled fiber chemical industry were held in Xiaoshan, Hangzhou.

More than 150 people, including industry leaders, experts and representatives from all over the country, have come together to explore the promotion of green recycling and upgrading of chemical fiber industry and sustainable high quality development.

Yu Jianyong, academician of the Chinese Academy of engineering, vice president of the China Chemical Fiber Industry Association, He Yanli, assistant director of the China Federation of chemical fiber industry, Hou Xiaoming, the director of the recycling economy Office of the national development and Reform Commission, Yang Chunping, the director of cleaner production room of the Chinese Academy of Environmental Sciences, Li Yanping, deputy director of the Supply Bureau of the Joint Logistics Department of the Central Military Commission, Gao Chengbin, vice president of the China clothing association, Secretary General of the China Household Textile Industry Association, Secretary General of the China Textile Industry Association, Zhang Zhi - hung, consultant of China Textile Research Institute Co., Ltd., director of Shanghai textile industry technology supervision institute, and general manager of Haiyan Haili environmental protection Fiber Co., Ltd.

According to statistics, recycling 1 tons of waste textiles is equivalent to 3.2 tons of carbon dioxide emission reduction. Compared with landfill or incineration, it can save land resources, protect the environment and reduce the consumption of crude oil resources.

As the trend of future development of chemical fiber recycling industry, how will we promote the green pformation and upgrading of the industry and the development of high quality?

In the past 40 years of reform and opening up, with the rapid development of China's chemical fiber industry, the recycling of chemical fiber industry has also undergone tremendous changes.

On the forum, He Yanli said that recycling chemical fiber industry is an integral part of the green development of the textile industry, and is one of the main directions of the comprehensive utilization of waste polyester bottles and waste textiles.

At present, China has become the first largest producer of regenerated chemical fibers.

Through recycling new technology, new technology and new equipment, the scale benefit of the chemical fiber industry is gradually emerging, and the achievements of scientific and technological innovation are increasing. Meanwhile, the average energy consumption and water consumption of the industry are significantly reduced.

The regenerated chemical fiber industry has brought into full play the advantages of production, learning, research and utilization, and has played the advantage of the joint advantage of the industrial alliance, improved the utilization rate of raw materials, reduced the production cost and improved the quality of products. A series of physical, chemical, and key technologies, technologies and equipment have made significant breakthroughs. Many technologies have won the "textile light" technological progress award of the China Textile Industry Federation, and the progress of product development is obvious.

Recycled polyester has the advantage of high gloss and high viscosity by using raw materials (bottles / tablets). New products of single function such as modification, compounding, blending, copolymerization, profiled, coloured and so on, have greatly expanded the application field and market space of products.

In particular, the development of coloring and regenerating chemical fibers from raw liquor can reduce the pollution of the environment while meeting the needs of coloring.

He Yanli pointed out that although the recycling of chemical fiber industry has made great achievements, there are still some problems.

The next step, recycling industry will start from the following aspects: first, rational response to the problem of raw material gap; two is to regenerate polyester standard conditions as the grasp, and strive to improve the competitiveness of the whole industry; three is to increase the comprehensive utilization of waste textiles; four is the use of advanced and suitable new technology, new technology, new equipment, promote industry pformation and upgrading; five is to strengthen international cooperation in all directions.

He Yanli also shared the theme of "mid 13th Five-Year review and review of China's chemical fiber industry".

In recent years, the capacity of the chemical fiber industry has increased rapidly, and the scale and application areas have been expanding. Structural adjustment and pformation, technological innovation drive, green manufacturing level, brand, standards and personnel construction have achieved remarkable results.

However, there are still some problems such as overcapacity in some industries, short board of high-tech fiber, urgent need for recycling system and level, and some national policies need to be improved.

In this regard, the future chemical fiber industry will continue to control the total quantity and optimize the stock, speed up the breakthroughs in key technologies and bottlenecks of high-tech fiber, promote green development in all directions, improve the standard and technical level of recycling chemical fiber, and vigorously promote the development of military and civilian integration, so as to promote the high quality development of the entire textile industry.

Overcome difficulties and face new challenges and challenges

At present, it is of great significance to actively promote the construction of recycling economy and recycle and reuse the chemical fiber industry, which is in line with the needs of ecological civilization construction.

Facing the new situation and new challenges, how should we deal with the common problems in the development of recycled fiber industry?

In this regard, Yu Jianyong made the theme report on the innovation and development of recycling technology of waste textiles.

Yu Jianyong introduced that in 2016, the total processing of China's textile fibers was 54 million 200 thousand tons, the recovery rate of waste textiles was less than 8%, and the utilization rate of waste textiles was low, resulting in a large consumption of oil and other resources and environmental pollution.

At present, the recycling of waste textiles in China is mainly faced with bottlenecks such as recycling, technology, market and economy. Next, we should pay attention to the classification of waste textiles, formulate recycling systems, use mechanical methods, physical methods, chemical methods and recycling technology to improve the utilization and utilization of waste textiles. At the same time, we should strengthen industry standards, promote industrial upgrading, establish and improve the standard system, and establish a safety evaluation system.

From the macro policy to the specific way of implementation, Yang Chunping elaborated on the development of circular economy and the promotion of green and high quality development.

Yang Chunping believed that the eighteen Party of the party opened the new era of China's ecological civilization construction, and the economy turned to high quality development.

The high quality development stage has a qualitative unity with the new era of ecological civilization construction, and green development is a universal form of high quality development.

The key to building ecological civilization and achieving high quality development is to promote green development and lifestyle.

In the future, we should build a green circular low carbon industrial system through the pformation of traditional industries to green storage and the development of green industries.

Green development should reflect on the traditional industrialization path of "pollution first and then harnessing", and explore the coordinated development path of economic growth, resource conservation and environmental protection.

Li Yanping made a brilliant report on the green development path of recycled fiber industry under the new situation.

The nineteen Party pointed out that in order to develop cleaner production industry, we are facing the new situation of the whole process of emission permit implementation, the supervision of unorganized emission measures, and the "green taxes".

Under such a new situation, enterprises are faced with 8 new challenges: sewage permit "one certificate management", "self certification and law-abiding" of pollutant discharge units, "dual control" of total and concentration of environmental management, sewage supervision from plant to production plant, strict compliance standard of pollutant discharge unit, disclosure of enterprise's "account book", strict tax collection and discharge of sewage charges, and "severe punishment" of excessive discharge of pollutants.

Therefore, it is necessary to implement the whole process of green cleaner production.

Among them, the formulation and implementation of cleaner production evaluation index system is conducive to forcing the traditional industry structure adjustment and optimization and upgrading, and promoting the pformation and optimization of traditional industries, leading the internationalization of science and technology innovation level in traditional industries.

Enterprises are the main body to promote the development of the industry. In the face of the new challenge of the competition of the chemical fiber giants and the demand of the high-end customers for the regenerated products, many enterprises have flexibly and intellectualized the original large devices, and adapt themselves to the new development pattern of the industry through technological innovation.

So, what are the demands and thoughts of enterprises in promoting the healthy development of recycled fiber industry and company?

Chen Hao introduced the development of the company in recent years, the new situation and new challenges facing the chemical fiber industry, and the countermeasures and suggestions.

He said Haiyan Haili was mainly engaged in the recycling and processing of waste PET bottles, and regenerated PET bottles were used as raw materials to produce regenerated polyester filament.

In 2014, Haili recycling industrial park was completed and put into operation, with an annual output of 150 thousand tons, regenerated PET bottles and regenerated polyester filament.

In the new situation, the recycling of chemical fiber industry faces severe challenges in raw materials, enterprises and products. We should increase the rate of self production and comprehensive utilization of raw materials, flexibly produce and differentiate products, implement technology upgrading in an all-round way, and benefit from meticulous management.

Chen Hao also put forward proposals to promote the standardization of recycled polyester industry, increase the tax rebate strength of recycling enterprises, speed up the revision of the industry standard of recycled polyester bottles, and let PET net import policy as soon as possible.

Xie Wei, technical engineer of Suzhou Baoli Di material Polytron Technologies Inc, put forward the thinking of the high quality development of masterbatch boosted recycled fiber.

In the process of regenerated fiber production, the mixture of color masterbatch and regenerated material is prone to cause various defects such as delamination and head and tail inequality. He proposes 5 solutions: regenerating heavy extruding chips and batten drum mixing, volume metering single batch masterbatch adding system, weightless single metering masterbatch adding system, multi metering monochrome Masterbatch mixing system and single metering masterbatch melt blending system.

At present, Suzhou Baoli Di has developed many kinds of products, such as regenerated black masterbatch, regenerated high color fastness Color Masterbatch, regenerated photochromic master batch, regenerated nano charcoal master batch, regenerated color flame retardant masterbatch and so on.

We can build a consensus and pool our minds to achieve win-win development.

Sun Yajun, general manager of Yizheng Zhongxing Environmental Protection Technology Co., Ltd., Lu Xiuqin, director of the Technical Supervision Institute of Shanghai textile industry, Wu Changmu, chief engineer of Beijing Zhongli Machine Engineering Technology Co., Ltd., Duan Furong of international terminal brand industry, Nagata Omasaki of Japan environmental design company, and Hao Shangkun, information manager of Zhejiang Huarui information Touchplus information Corp, have brought the theme of "regenerative fiber development status and trend", "recycling and reuse of chemical fiber standardization system construction and suggestions", "high quality differential regeneration polyester fiber production and intelligent equipment technology", "international terminal retail brand global sustainable development strategy 2025", "JEPLAN chemical / bottle to bottle BHET recycling process", and "renewable polyester market operation and development" theme sharing.

Under the background of China's entry into the new era, the chemical fiber industry is not only an important raw material industry in the textile industry, but also an industry with international competitive advantages and an important pillar industry for the overall competitiveness of the textile industry. It is an important part of the national strategic emerging industries, and the recycling industry has also made a major breakthrough.

The convening of this conference will further promote circular recycling of resource conservation in a comprehensive manner, effectively reduce environmental pressure and achieve sustainable and healthy development of the chemical fiber industry.

At the annual meeting of the regenerated chemical fiber Committee of China Chemical Fiber Industry Association 2018, the reclaimed chemical fiber Specialized Committee was renamed the chemical fiber Association of China Chemical Fiber Industry Association, and the successful completion of the change was completed. The chemical fiber industry association of China announced the formal establishment of the chemical fiber branch.

At the meeting, Haiyan Haili environmental protection Fiber Co., Ltd. was elected chairman of the unit, the company's general manager Chen Hao as the chairman of the new recycling chemical fiber branch, the China Chemical Fiber Industry Association Lin Shidong served as vice president, the China Chemical Fiber Industry Association Li Deli served as the secretary general, and the China Chemical Fiber Industry Association Li Boming served as deputy secretary general.

In addition, 10 leading enterprises of the recycled fiber industry were elected vice chairman units.

At the meeting, the president, vice president, members and representatives of the new conference agreed that they would continue to support the work of the association and the branch as always. In the future work, they should respond positively to the policy call, adhere to green production, green manufacturing, establish industry self-discipline, guide green consumption, and attach importance to the work of standardization; propose to speed up the docking of industry and policy, raise the entry requirements for standard conditions and avoid disorderly competition; and believe that the sustainable development of the chemical fiber industry in an orderly and healthy green orbit will surely have a higher, better and farther prospect.
