Duan Xiaoping, Vice President of China Textile Industry Federation and President of China Chemical Fiber Industry Association, Yao Mu, Academician of Chinese Academy of Engineering, Yu Jianyong, Academician of Chinese Academy of Engineering, China National Chemical He Yanli, Vice President of Fiber Industry Association, Wang Yuping, Vice President of China Chemical Fiber Industry Association, Lu Honggang, Vice President of China Textile Machinery Association, Wang Huaping, Vice President of Research Institute of Donghua University, Lu Weidong, Vice Mayor of Nantong Municipal People’s Government and Secretary of Hai’an County Party Committee Sun Jinji, former director of the Standing Committee of the Hai’an County People’s Government and leader of the Hai’an Nylon Industry Development Leadership Group, Lu Zhongping, member of the Standing Committee of the Hai’an County Party Committee/Deputy County Mayor of the Hai’an County People’s Government, and Gu Yantie, Secretary General of the Hai’an Chemical Fiber Industry Chamber of Commerce, and other leaders and Nearly 600 experts, business representatives, and media participated in the forum to discuss the technical issues of recycling and reuse of waste textile resources and to express their insights on its future development trends.
Lu Weidong, Secretary of the Hai’an County Party Committee, introduced in his speech that chemical fiber is one of the traditional industries of Hai’an’s industrial economy. There are more than 200 chemical fiber enterprises in the county, including more than 70 enterprises above designated size. In 2016, sales of more than 15 billion yuan were achieved. The annual output of nylon yarn It reaches 400,000 tons and is widely used in civil, industrial, military and other fields. In the future, Haian has established six major enhancements, strengthened organization and coordination, strengthened forward and backward extension, strengthened technological innovation, strengthened team building, strengthened policy support, and strengthened industry guidance.
Regarding the current status and development trend of waste textile resource recycling technology, Wang Huaping, vice president of Donghua Research Institute, believes that at present, the comprehensive recovery rate of waste chemical fiber textiles and polyester bottle flakes in my country is insufficient, while the recycling rate of polyester bottle flakes and textiles in Japan The rate is 84%, 49% in Europe and 29% in the United States. Every year, more than 1 million tons of textile and garment waste in China are buried and incinerated as garbage, which not only causes a waste of resources, but also pollutes the environment. In addition, the number of idle and used clothing exceeds 28 million tons. Development trend, PET recycling technology-high efficiency and high value. The recycled direct spinning technology of polypropylene fiber-high efficiency, the regeneration technology of polypropylene fiber-gradient utilization.
Wang Huaping also made suggestions on existing policies, strengthened the construction of the certification system, and encouraged the development of industrial superior enterprises. Build the four systems of recycling, recycling, evaluation and application of the recycling development of waste chemical fiber textile resources in my country. Provide solutions for the entry threshold, equipment and technical specifications of the recycling industry, raw material specifications and product standards, clean production standards for the recycling industry, and the establishment of an energy-saving emission reduction system, and strengthen personnel training and base construction. Strengthen the establishment of product ecological safety standards, increase government procurement and professional customization, propose a textile recycling system and management plan suitable for China, and propose a recycling product performance evaluation, quality evaluation and safety evaluation system, scientific guidance and publicity, and increase consumer recognition Spend. Strengthen overall policy design, coordination of the entire industry chain, full logistics coverage, research covering the full-process recycling development system of raw material traceability, technical equipment, production process, and product application, and establish demonstration bases. Formulate special taxation and development policies.
The technical and economic discussion of recycling waste textiles with polyester as the main component by chemical methods, Wang Shaopeng, general manager of Shanghai Juyou Chemical Co., Ltd., pointed out that garbage is a misplaced resource, and the use of recycled polyester requires a change in people’s consumption concepts. Government policies Support, industry rules and regulations, the formulation of product standards, scientific and technological innovation, recycling companies need perseverance, patience, and determination. Promoting the development of waste polyester recycling technology can reduce the polyester industry’s dependence on petroleum and realize the sustainable development of the industry. Recycling engineering technology companies must have a sense of responsibility to improve recycling technology and increase the high value and added value of recycled products.
Wu Anfu from Li Ning Sporting Goods Co., Ltd. has his own view on sports functional fabrics’ innovation demands for environmentally friendly fibers. Consumer orientation is not just empty talk. Product innovation should break the focus on R&D from a technical perspective, and be distinctive from the perspective of consumers. Such innovation It is effective innovation. From the standpoint of consumers, put forward several development suggestions: clothing and skin changes, temperature, humidity, moisture and water vapor; sports functions and customer experience, more professional, more refined, more unique and healthier, for example, study the muscles of athletes Group classification, clothing line design should be divided according to muscle lines, otherwise it will be uncomfortable, but also according to the human body motion state research and development, different exercise methods, clothing requirements are also different. The functional fabric developed in the past is how to better wick away sweat after the human body sweats. The current demand is how to solve the environment when the human body sweats slightly and reduce the amount of sweating by changing the vaporization state of the human body.
Research on the continuous regeneration of polyester technology by chemical method, Zhang Shuo, deputy general manager of Zhejiang Luyu Environmental Protection Co., Ltd., the principle of recycling waste textile resources: do not cause secondary pollution of the environment due to recycling; do not consume a lot of energy due to recycling (energy = Resources); renewable products still have the possibility of recycling and form a closed loop of resources; the safety of renewable products must be guaranteed; in certain areas, the quality of renewable products must meet or exceed that of original products. Recommendations for the development of recycling and recycling of waste textiles: formulate standards for the classification and recycling of waste textile raw materials after consumption; formulate standards for the recycling of waste textile fiber waste in industrial enterprises, implement certification and filing systems for waste textile recycling companies, and prevent disorderly discharge and environmental pollution; Choose different technologies according to different grades of raw materials, carry out diversified recycling, maximize the added value of the final product, and avoid the waste of raw materials by a single treatment method; advocate green procurement, and introduce specific measures to encourage the application of recycled textiles from the government level to encourage Terminal consumer product manufacturers choose recycled textile fibers as raw materials; cooperate with industry associations and terminal brand owners to guide the public's consumption concepts through certification and publicity, and improve the social image of recycled products. He also urged that the production and operation of waste chemical fiber by one or two companies alone cannot fully maximize social benefits. To better control waste of resources and environmental pollution, more companies and scholars are required to devote themselves to the business and pass the demonstration park. With the support of leaders, we will continue to expand the scale of recycled textiles and realize the sustainable development of the polyester chemical fiber industry.
At the meeting, Zhang Li, deputy general manager of the Green Environment Department of Intertek Tianxiang Group, talked about the application and significance of life cycle assessment LCA in circular economy. Zhang Jiangang, general manager of Beijing Sanju Sunshine Intellectual Property Agency Co., Ltd., introduced the intellectual property risks and avoid. Xue Haijun, director of the Hai'an Chemical Fiber Industry Cultivation Office, honorary chairman of the Hai'an Chemical Fiber Chamber of Commerce, and director of the Hai'an State Taxation Bureau, focused on the development and investment environment of the Hai'an chemical fiber and high-end textile industry.
Duan Xiaoping presided over the interactive session and asked the guests on stage on hot issues in the recycling of waste textile resources and bottle flake recycling projects. Academician Yao Mu proposed to standardize the recycling and processing of waste textiles. In addition, as the functions of clothing and home textiles are becoming more and more diversified, and the proportion of blending is increased, the national government is required to lead, and planning is also needed to expand the recycling and utilization of waste textiles. scale.
Xu Weilin puts forward four suggestions. One is to pay attention to the recycling of waste textiles at the national level; the other is to further improve the level of classification technology and expand the classification channels at the technical level; the third is that the standard is very important, and the bottle sorting should be restricted from the source. Because consumers are worried about the virus, they need to disinfect waste textiles. Fourth, the recycled textiles produced must also have standards so that consumers can use them with confidence.
He Yanli emphasized three ideas. One is to solve the problem of opening up second-hand clothing; the other is that it is very important that waste textiles that cannot be used be sorted and disinfected. Sorting standards must be formulated. The more scientific the sorting, the more meticulous it is for downstream utilization. Value; Third, the recycling rate of waste textiles is still very low, and domestic bottle flake companies need to be bigger and stronger. At present, 28 companies are listed as qualified companies. Our gap lies in the fact that waste textiles have not been well utilized, and the consumption of materials is not humane enough, and we need to gradually change the current state to achieve a closed loop.
Wang Huaping believes that the scale of bottle flake renewable resources should be increased, but at the same time energy consumption should be reduced and the barriers to entry should be raised. At present, it is recommended that enterprises do a good job in the recycling of pure polyester textiles, or the recycling of textiles with a high proportion of natural fibers, and it is not easy to recycle textiles with a similar proportion of multi-components.
During the interaction, Zhang Shuo said that effective channels should be established to recycle and classify waste textiles for industrial and civil use clearly, and to recycle pure and blended textiles separately. Ensure that enterprises participating in the recycling cycle of waste textile resources have sound pollution treatment measures and the management level reaches a certain level. Relying on industry self-discipline is not enough, we must standardize and implement a certification system.
