To meet the needs of high-quality development



According to statistics, recycling 1 ton of waste textiles is equivalent to reducing 3.2 tons of carbon dioxide emissions, compared with landfill or incineration treatment, can save land resources, protect the environment, reduce the consumption of crude oil resources and so on. As the future development trend of chemical fiber recycling industry, how to promote the green transformation and upgrading of the industry and high-quality development?



In the past 40 years of reform and opening up, with the rapid development of China's chemical fiber industry, great changes have taken place in the recycling chemical fiber industry. At the forum, He Yanli said that the recycling chemical fiber industry is an integral part of the green development of the textile industry and one of the main directions for the comprehensive utilization of waste polyester bottles and textiles. At present, China has become the largest producer of regenerated chemical fibers.



By adopting new technology, new technology and new equipment, the scale benefit of the chemical fiber recycling industry gradually appears, the achievements of scientific and technological innovation are increasing, and the average energy consumption and water consumption of the industry are obviously decreasing. The regenerated chemical fibre industry gives full play to the advantages of production, learning, research and utilization, brings into play the joint public relations advantages of the industrial alliance, improves the utilization rate of raw materials, reduces production costs and improves product quality. A series of physical and chemical methods have made significant breakthroughs in key processes, technologies and equipment for recycling and reuse, and many technologies have won the award of China Textile Industry Federation-ldquo. Light of Weaving & rdquo; Science and Technology Progress Award, product development progress is obvious. Regenerated polyester fibers use raw materials (bottles/flakes) with the inherent advantages of high brightness and viscosity, and adopt single-function differentiated new products such as modification, compounding, blending, copolymerization, abnormity and colour, which greatly expands the application field and market space of the products. Especially, the regenerated chemical fibers dyed with raw liquor have been developed, which can meet the needs of colored fibers and reduce the pollution to the environment at the same time.



He Yanli pointed out that although great achievements have been made in recycling chemical fibers industry, there are still some problems. Next, the recycling industry will start from the following aspects: first, rationally cope with the shortage of raw materials; second, strive to improve the competitiveness of the whole industry with regenerated polyester standard conditions as the starting point; third, increase the comprehensive utilization of waste textiles; fourth, use advanced and applicable new technologies, new processes, new equipment to promote the transformation and upgrading of the industry; fifth, strengthen the whole country in an all-round way. International cooperation.



He Yanli also made the theme sharing of “ China Chemical Fiber Industry ‘ 13th Five-Year Plan & rsquo; Mid-term Assessment Review and Prospect & rdquo. In recent years, the chemical fibre industry has witnessed rapid growth in production capacity, expanding scale and application fields, and remarkable achievements have been made in structural adjustment and transformation, science and technology innovation drive, green manufacturing level, brand, standards and talent building. However, there are still some problems, such as overcapacity in some industries, high-tech fiberboard, recycling system and level need to be improved urgently, and some national policies need to be improved. In this regard, the future chemical fiber industry will continue to insist on controlling the total amount and optimizing the stock, speed up the breakthrough of key technologies and bottlenecks of high-tech fibers, promote green development in all directions, improve the standard and technical level of recycling and reusing chemical fibers, and vigorously promote the development of civil-military integration, so as to promote the high-quality development of the textile industry as a whole.



Overcoming difficulties and facing new situations and challenges < br />


At present, it is of great significance to actively promote the construction of circular economy and the recycling and reuse of chemical fiber industry, which meets the needs of the construction of ecological civilization. Faced with the new situation and challenges, how to deal with the common problems in the development of recycling chemical fiber industry?



In this regard, Yu Jianyongzuo & ldquo; Innovation and Development of Recycling Technology of Waste Textiles & rdquo; Theme Report. Yu Jianyong introduced that in 2016, China's textile fiber processing total was 54.2 million tons, and the recovery rate of waste textiles was less than 8%. The low utilization rate of waste textiles caused a large consumption of oil and other resources and environmental pollution. At present, the recycling of waste textiles in China is mainly faced with the bottlenecks of recycling, technology, market and economy. The next step is to pay attention to the classification of waste textiles, formulate a recycling system, use recycling methods such as mechanical method, physical method, chemical method and recycled polyester fiber preparation technology to improve the utilization rate and utilization capacity of waste textiles, and at the same time, strengthen industry norms. Promote industrial upgrading, establish and improve the standard system, and establish a safety evaluation system.



Yang Chunping progressively elaborated his thoughts on developing circular economy and promoting green and high-quality development from macro-policies to concrete ways of realization. Yang Chunping believes that the 18th National Congress of the CPC has opened a new era of China's ecological civilization construction, and the economy has turned to high-quality development. The stage of high-quality development 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 mode and lifestyle. In the future, we should build a green cycle low-carbon industrial system through greening the stock of traditional industries and vigorously developing green industries to optimize the increment. In green development, we should reflect on the traditional way of industrialization - ldquo, pollution first, and pollution control - rdquo, and explore the coordinated development 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 Nineteenth National Congress of the CPC pointed out that in order to develop cleaner production industry, we are now facing the whole process supervision of pollutant discharge permit implementation and the supervision of unorganized emission measures. Environmental protection tax has not been & LDQUo; equal treatment & rdquo; new situation. Under this new situation, enterprises are faced with discharge permit & ldquo; certification management & rdquo; & discharge unit & ldquo; self-certification & law-abiding; & total amount and concentration of Environmental Management & ldquo; dual control & rdquo; & emission supervision from plant area to production device, strict judgment criteria of discharge unit abiding by law, Enterprise & ldquo; account book & rdquo; public, discharge & ldquo; fee-tax-changing & rdquo; strict collection of taxes and over-standard discharge. Pollution & ldquo; Heavy Legal Punishment & rdquo; 8 New Challenges. Therefore, it is necessary to implement the whole process of green cleaner production. Among them, the formulation and implementation of the evaluation index system of cleaner production is conducive to impelling the structural adjustment and optimization and upgrading of traditional industries, driving the continuous transformation and optimization of traditional industries, and leading the internationalization of the level of scientific and technological innovation in traditional industries.



The prospect of recycling and regenerating chemical fibers is broad < br /> with the development of enterprises.


Enterprises are the main body to promote the development of the industry. Faced with the new competition challenges of chemical fiber giants and the demand of high-end customers for renewable products, many enterprises have carried out flexible and intellectualized transformation of the original equipment to adapt to the new pattern of industry development through technological innovation. Then, what are the demands and considerations of enterprises to promote the healthy development of the recycled fiber industry and the company?



Chen Hao introduced the company's development in recent years, the new situation and challenges faced by the recycling chemical fiber industry, and the ideas and suggestions to deal with them. He said Haiyan Haili is mainly engaged in the recycling and processing of waste polyester (PET) bottles and the production of recycled polyester filaments from recycled PET bottle flakes. In 2014, Haili Recycling Industrial Park was completed and put into production, with an annual output of 150,000 tons of recycled PET bottles and recycled polyester filaments. It has built a green environmental protection demonstration park and a smart factory in an all-round way. Under the new situation, the recycling chemical fiber industry is facing severe challenges in raw materials, enterprises and products. It is necessary to improve the self-productivity and comprehensive utilization rate of raw materials, flexible production and differentiate products, implement technical upgrading in an all-round way, and benefit from fine management. Chen Hao also put forward some suggestions, such as promoting the standardized renovation of the recycled polyester industry, increasing the tax reduction of the recycled polyester bottle enterprises, speeding up the revision of the recycled polyester bottle industry standards, and landing the policy of importing PET net sheets as soon as possible.



Xie Wei, technical engineer of Suzhou Politi Material Science and Technology Co., Ltd., put forward the idea that masterbatch can promote the high quality development of regenerated fibers. Faced with various shortcomings such as layering and uneven head and tail caused by mixing of color masterbatch and reclaimed material in the production process of regenerated fibers, he proposed five solutions: mixing of regenerated re-extrusion chip and master batch drum, volume single-measure master batch adding system, weightlessness single-measure master batch adding system, multi-measure single-color master batch mixing adding system and single-measure master batch melt mixing adding system. At present, Polydi Suzhou has developed a variety of products, such as regenerated black masterbatch, regenerated color masterbatch with high color fastness, regenerated photochromic masterbatch, regenerated nano-bamboo charcoal masterbatch, regenerated color flame retardant masterbatch and so on.



Only by uniting common understanding and brainstorming can we achieve win-win development. Sun Yajun, General Manager of Yizheng Zhongxing Environmental Protection Technology Co., Ltd., Lu Xiuqin, Director of Shanghai Textile Industry Technical Supervision Institute, Wu Changmu, Chief Engineer of Beijing Zhongli Machinery Engineering Technology Co., Ltd., Duan Furong, Practitioner of International Terminal Brand Industry, Takao Tai Zhengshu, President of Japan Environmental Design Corporation, and Hao Shangkun, Information Manager of Zhejiang Huarui Information Co., Ltd., were brought in separately.
