　　 The proposal of "carbon neutralization" puts forward new requirements for the development of the industry. The lightweight characteristics of carbon fiber and its composites play an important role in promoting energy saving and consumption reduction. Green energy such as wind power, photovoltaic and other industries need a lot of carbon fiber, but the production of carbon fiber itself needs to consume a lot of electricity. With the improvement of wind power technology, its cost is getting lower and lower. Can wind power be used to reduce the cost of carbon fiber? In his speech, Yan Bing, the industrial tutor of the Department of materials and chemistry of Suzhou University, proposed a new energy ecosystem. In this system, carbon fiber can be used as wind turbine blades to produce hydrogen, which can promote the development of hydrogen energy vehicles. At the same time, the demand for gas stations increases, so it is necessary to build more distributed wind turbine stations for hydrogen production. Hydrogen vehicles need carbon fiber, and wind power also needs carbon fiber. This mutual promotion can promote the growth of quantity and the decrease of cost, which is a perfect industrial chain for carbon fiber industry. 　

　　 Green Development Forum of chemical fiber industry

　　 Explore the practical path to achieve the goal of "double carbon"

　　 During the 14th Five Year Plan period, under the guidance of green development and double carbon goals, the chemical fiber industry, together with the whole textile industry chain, undertakes the social responsibility of green manufacturing and ecological protection, and independently undertakes the important mission of developing diversified biological raw material resources, improving the recycling level of fiber products, and reducing carbon emissions of industrial enterprises.

　　 At the green development forum of chemical fiber industry, Wang Huaping, researcher and doctoral supervisor of School of materials, Donghua University, introduced the technical route and industrial development direction of bio based chemical fiber. He said that as of 2019, the total production capacity of bio based chemical fiber will reach 5 million tons / year, and the scale production of bio based synthetic fiber, new bio based cellulose fiber and marine bio based fiber has been realized, and the application technology is mature and the application fields are constantly expanding. In the future, the development trend of bio based fiber will focus on integration development, including technology integration and innovation integration development, bio based fiber and green fiber integration, green manufacturing integration development, industrial chain innovation chain integration development, terminal brand integration development, recycling integration development, life cycle integration development, sustainable integration development and so on.

　　 Plastic particles are an unavoidable problem in the sustainable development of chemical fiber industry. Clothes washing and wearing are the important sources of fiber microplastics in the environment. This kind of fiber microplastics can not be degraded, causing great pressure on the ecological environment and causing serious harm to human health. Li Guang, a professor at the school of materials science and engineering, Donghua University, introduced several strategies to inhibit or block the release of fiber microplastics from clothing. She pointed out that the discharge of laundry wastewater is the main way for fiber micro plastics to enter the environment. In order to inhibit the production of fiber microplastics in the washing process, filters and laundry bags can be added at the outlet of washing machines; The surface of nylon fabric can be treated by coating and functional treatment with modified pectin.

　　 In response to the call of national carbon peak and carbon neutralization goals, reducing carbon emission intensity and total amount of chemical fiber industry is an important development task for a long period of time in the future. Liu Shiyang, project manager of China Chemical Fiber Industry Association, analyzed the key points of carbon emission calculation and the influencing factors of carbon footprint of chemical fiber industry, and explained the related research results of carbon emission of chemical fiber industry.

　　 At the enterprise level, the influencing factors of carbon accounting mainly include energy consumption intensity and total amount, energy structure and product structure. The accounting boundary of product carbon footprint is generally from the acquisition of raw materials, the production of energy and materials, the manufacture and use of products, and the treatment and final disposal of products at the end of their life. At present, according to the purpose of enterprises, accounting boundary is often defined as "cradle to gate" and "gate to gate". Cradle to gate involves the acquisition and manufacturing of raw materials. "Gate to gate" only includes the manufacturing phase (regardless of the manufacturing of raw materials and their environmental loads).

　　 Zheng Guo, vice chairman of the industrial surfactant Committee of China Fine Chemical Industry Association and member of the oil additive branch of China Chemical Fiber Industry Association, introduced that after years of development, China has developed dozens of finishes with independent intellectual property rights for different fiber varieties, and realized batch production and application. However, the output and varieties still can not meet the requirements of the rapid development of the chemical fiber industry. A large amount of oil is still needed to be imported every year, especially in filament fiber (POY, FDY) finishes. About 80% of the market is in the hands of Japanese and German enterprises, almost monopolized by foreign countries. In this regard, China still needs to focus on solving the "neck sticking" problem of imported finishes used in functional fibers on domestic chemical fiber industry.

　　 The sustainable development of the industry is closely related to the individual enterprises actively fulfilling their social responsibilities and promoting green and low-carbon development. At the forum, enterprise leaders from Saideli, Quanzhou Haitian and Zhejiang Jiaren shared the experience and achievements of chemical fiber enterprises in the exploration and practice of green development on "sustainable vision construction of chemical fiber enterprises", "exploration and sharing of green fiber application", "Research on frontier technology of waste textile recycling", etc.

　　 Sun Jian, vice president of enterprise communication and sustainable development of Saideli, introduced the contents of Sedley's vision of sustainable development in 2030. In terms of climate and ecosystem protection, Sedley strives to reduce carbon by 30% by 2030. Strive to achieve net zero carbon emissions by 2050. In the aspect of closed-loop cleaner production, we should establish a clean closed-loop production system to minimize the emission of harmful substances, and strive to achieve zero harm production by 2030. In terms of innovation and circular economy, we should promote circular economy through value chain innovation and multi-party cooperation, and create a circular man-made cellulose fiber industrial chain. In terms of inclusive growth, efforts should be made to ensure the health and safety of employees and communities, and create common values and prosperity through care and empowerment.

　　 Since the green fiber label and product certification work carried out by China Chemical Fiber Industry Association, the number of green fiber certification enterprises has been expanding. With the development of green consumption concept, the application field of green fiber is also expanding. As the first downstream enterprise to obtain the certification of green fiber products in China, Su Yubi, general manager of Quanzhou Haitian Materials Technology Co., Ltd., introduced the development of Haitian green fiber products and products at this forum. From the perspective of product types, at present, the green fiber products of Haitian materials include: recycled polyester / recycled nylon fiber, color masterbatch environmental protection fiber, and bio based environmental protection fiber. Ecorona is a recycled product made from recycled polyester bottle pieces through special process treatment. It has been successfully applied to various products of Haitian and has won high praise from customers.

　　 The technical problems of waste textile recycling have been concerned. China is a big textile producer, but the recycling rate of waste textiles is low. The traditional physical recovery method can not realize the permanent recycling of waste textiles, and the existing chemical methods can not meet the development needs of high value recycled polyester products. Zhejiang Jiaren new materials Co., Ltd. uses waste polyester materials such as waste clothes and leftovers as raw materials to produce high-quality, multi-functional, traceable and permanent recycling polyester fiber. According to Guan Jun, deputy chief engineer of Zhejiang Jiaren new materials Co., Ltd., Jiaren took the lead in independently innovating the industrial production demonstration line of 10000 ton chemical recycling polyester. Its technical route is alcoholysis transesterification to realize high-value recycling of waste textiles. The core technologies include: pretreatment technology, synthesis and refining technology of regenerated DMT, preparation of high-purity DMT and utilization of by-products. The process has the advantages of convenient purification of regenerated monomer, wide applicability of raw materials, mild reaction conditions and low equipment requirements.
