Duan Xiaoping, vice president of China Textile Industry Federation and President of China Chemical Fiber Industry Association, academician of Chinese Academy of Engineering Yao Mu, academician of Chinese Academy of Engineering Yu Jianyong, vice president of China Chemical Fiber Industry Association and He Yanli Wang Yuping, Vice President of Chemical Fiber Industry Association, Lu Honggang, Vice President of China Textile Machinery Association, Wang Huaping, Vice President of Donghua University Research Institute, Lu Weidong, Vice Mayor of Nantong Municipal People's Government and Secretary of Hai'an County Committee, Sun Jinji, Chairman of Standing Committee of Hai'an People's Government and Leading Group of Hai'an Nylon Industry Development, Lu Zhongping, Vice-County Governor of Hai'an County Standing Committee/Hai'an County People's Government, Gu Yantie, Secretary-General of Hai'an County General Chamber of Commerce of Chemical Fiber Industry and other leaders and experts, as well as representatives of enterprises and media nearly 600 people participated in the forum. They jointly discussed the technical issues of waste textile resources recovery and reuse, and expressed their true knowledge of the future development trend. A burning view.
In his speech, Lu Weidong, Secretary of Hai'an County Party Committee, introduced that chemical fiber is one of the traditional industries of Hai'an industrial economy. There are more than 200 chemical fiber enterprises in Hai'an County, of which more than 70 are large-scale enterprises. In 2016, more than 15 billion yuan were sold, and the annual output of nylon filament reached 400,000 tons. It is widely used in civil, industrial and military fields. In the future, Hai'an has established six major strengthening measures: strengthening organizational coordination, strengthening forward and backward extension, strengthening technological innovation, strengthening team building, strengthening policy support and strengthening industry guidance.
Wang Huaping, vice president of Donghua Research Institute, thinks that the comprehensive recovery rate of waste chemical fiber textiles and polyester bottle flakes in China is insufficient at present, while the recovery rate of Japan's polyester bottle flakes and textiles is 84%, Europe's 49% and the United States'29%. Every year, more than one million tons of textile and clothing waste are buried and burned as garbage, which not only wastes resources, but also pollutes the environment. In addition, there are more than 28 million tons of casual clothing. Development trend, PET's regeneration technology - high efficiency and high value. Polypropylene regenerated direct spinning technology - high efficiency, polypropylene regeneration technology - gradient utilization.
Wang Huaping also put forward suggestions for the existing policies, strengthen the construction of the certification system, and encourage the development of industrial advantage enterprises. Four systems of recycling, recycling, evaluation and application of waste chemical fiber textile resources were constructed. To provide a plan for the entry threshold of the regeneration industry, equipment and technical specifications, raw material and product standards, clean production standards of the regeneration industry and the establishment of energy saving and emission reduction system, and to strengthen the training of talents and base construction. We should strengthen the construction of ecological safety standards for products, increase government procurement and specialized customization, put forward textile recycling systems and management plans suitable for China, and put forward recycled products performance evaluation, quality evaluation and safety evaluation system, scientific guidance and publicity, and improve consumer recognition. Strengthen the overall policy design, the whole industry chain coordination, the whole logistics coverage, research covers raw material traceability, technical equipment, production process and product application of the whole process of recycling development system, establish a demonstration base. Formulate tax and development special policies.
Discussing the technology and economy of recycling waste textiles with polyester as the main component by chemical method To learn technological innovation, regenerative enterprises need perseverance, patience and determination. Promoting the development of waste polyester recycling technology can reduce the dependence of the polyester industry on petroleum and realize the sustainable development of the industry. Regeneration engineering technology companies should be more responsible to enhance recycling technology, improve the value of recycled products and added value.
Wu Anfu of Li Ning Sports Goods Co., Ltd. has his own view on the innovative demands of sports functional fabrics on environmental protection fibers. Consumer orientation is not empty words. Product innovation should break the focus on technical research and development, and from the consumer point of view should have characteristics. Such innovation is effective innovation. From the consumer's point of view, several suggestions are put forward: changes in clothing and skin, temperature, humidity, moisture and moisture; sports functions and customer experience, more professional, more refined, more unique and healthier. For example, studying the classification of athletes'muscle groups, clothing lines should be divided according to muscle lines, otherwise it will be uncomfortable. Clothing should also be researched and developed according to the state of human motion. Different methods of motion require different clothing requirements. Previously developed functional fabrics are how the body sweats after a better sweat, now the need is how to change the body's vaporization state, when the body sweats slightly to solve the environment, reduce a large number of sweats.
Research on continuous chemical regeneration of polyester technology, Zhang Shuo, deputy general manager of Zhejiang Luyu Environmental Protection Co., Ltd. Principles of recycling waste textile resources: no secondary pollution caused by recycling; no large amount of energy is consumed due to recycling (energy = resources); recycled products still have the possibility of recycling, forming a closed loop of resources The safety of the recycled products must be guaranteed, and the quality of the recycled products should reach or exceed the original products in certain areas. Suggestions for the development of recycling of waste textiles: to formulate classification and recycling standards for waste textile raw materials after consumption; to formulate recycling standards for waste textile fiber waste in industrial enterprises; to implement certification and filing system for waste textile recycling enterprises; and to put an end to this problem
