2022/4/15 20:35:00 0

　　 After more than 40 years of development since the reform and opening up, China's textile industry has become the world's largest producer, consumer and trading country of textiles and clothing. The fiber processing volume accounts for more than 50% of the world, and the total export volume of textiles and clothing accounts for more than one third of the world. China's textile industry has long been practicing the transformation and upgrading to the direction of energy saving, low-carbon and green, making contributions to the green and sustainable development of China's and global textile industry.

　　 In order to better guide enterprises to implement the double carbon target, textile and clothing weekly specially set up a series of reports on "implementing double carbon, industry in action", which is divided into fiber, fabric and clothing. It introduces the green development experience of benchmarking enterprises in the industrial chain in detail, so as to set a model for the industry.

　　 Fiber

　　 All things are born when they are of their own nature, and they are made of everything by their way. At present, the international situation is complex and the world economy is uncertain. However, the global green and low-carbon development is irreversible. With the voice of "carbon peaking, carbon neutralization" rising in the global scope, in the new development stage of China's textile power goal basically achieved, the textile and clothing industry with green, low-carbon, recycling as the characteristics of the new economic form accelerated.

　　 How clear is the canal? For a source of fresh water. As the source of the whole textile and clothing industry, the fiber yarn field is speeding up the exploration of green manufacturing system with green materials, clean production, green certification and circular development as the core. It is committed to establish a "wind vane" of green and low-carbon development from the source, reduce the carbon footprint output to the downstream, play the "leverage effect", and promote the green transformation of the whole textile industry chain.

　　 In the process of "carbon peak and carbon neutralization", a large number of leading enterprises such as Fujian Yongrong Jinjiang, Dezhou Huayuan, Tangshan Sanyou and Qingdao bond have emerged in the field of fiber yarn. Some of these enterprises reduce energy consumption and improve production efficiency through intelligent manufacturing and photovoltaic power generation. Some of them reduce pollution and enable great health by developing and producing new technologies and materials such as natural plant degradable, recycled regenerated fiber and dyed fiber. Some of them participate in the "30.60 carbon neutral acceleration plan for climate innovation action of Chinese fashion brands", Join hands with downstream partners of industrial chain to win a green future.

　　 one 　 Green materials 　 Reduce carbon footprint output to downstream

　　 Green development, materials first. It is a wise move for the industry and enterprises to reduce the burden of the earth from the source of textile and explore a new path of sustainable development. Under the background of "science and technology, fashion and green" becoming the new positioning of textile industry, many fiber yarn enterprises begin to seek breakthroughs in the field of green new materials, and bring more sustainable and low-carbon textile materials for the industry from the beginning of product life cycle.

　　 As one of the leading enterprises in the field of regenerated cellulose fiber, Tangshan Sanyou group Xingda Chemical Fiber Co., Ltd. has always advocated green development and circular economy, forming a low-carbon, carbon reduced green product structure system. For example: Eco Tang ®， Compared with the viscose fiber that does not reach the eubat technology, it can save 24L of water per kilogram and reduce the carbon emission by 2.89kg; Regenerated fiber revisco ™， The recycled waste textile and wood pulp were used as raw materials to realize the recycling of waste cotton textiles; Tangsi ® Color fiber, through the injection technology before spinning, organically combines cellulose fiber with environmental protection pigments to reduce the dyeing and finishing process in the later stage, using 1 kg tangsi ® Color fiber can reduce water by about 100L and carbon emission by 4.23kg. In addition, Sanyou chemical fiber has also developed bamboo charcoal fiber, antibacterial fiber, far-infrared fiber and other functional new material fibers.

　　 In order to actively implement the "double carbon" goal, this year, Dezhou Huayuan Ecological Technology Co., Ltd. launched "new sequence of twelve colors" for color spinning plate. Combined with the popular trend, it presents colors associated with solar terms every month, outputs traditional culture, and lets customers experience the pleasure of color renewal. In terms of color matching and production methods, the "new sequence 12 colors" focuses on energy saving and consumption reduction. Combined with the absolute advantages from the raw materials, green environmental protection materials, such as regenerated polyester, regenerated cellulose fiber and degradable fiber, can be used for infant and underwear dyeing, further deepening and expanding energy conservation and emission reduction, and taking a big step forward in response to the goal of dual carbon.

　　 At present, green textile materials have become a new trend in the development of the industry. As a leading functional fiber innovation enterprise in China, Qingdao Bangte Ecological Textile Technology Co., Ltd. at the beginning of its establishment, it adhered to the concept of green environmental protection, adopted pure natural raw materials, and built naturefi with plant innovation power ® Plant force fiber platform. The company's plant fibers such as ice Mint fiber, warm ginger fiber, Tiancha fiber, isatis root fiber, etc., functional products such as intelligent temperature regulating series, heating and warming series, cold touch series, as well as plant extraction technology, microcapsule technology, biological regeneration technology, aerogel technology and other innovative breakthroughs, have a great influence in the domestic and foreign markets.

　　 When the "double carbon target" has a time line, the sustainable development of enterprises has a clear direction. In the past year, in the face of severe domestic and international situation, many enterprises adhering to the main line of green development have achieved remarkable results. In 2021, Fujian Yongrong Jinjiang Co., Ltd. will see a growth of over 20% in the sales of raw dyed fibers, 300% of regenerated fibers and 15% of functional fibers; In 2021, Dezhou Huayuan launched renewable viscose, zero carbon fiber, degradable fiber and other sustainable raw material products, creating a plant leaf color wood language ™、 Carbon footprint measures carbon star ™ And other green differential yarn brands, the company's yarn output, export earnings have reached a record high, and achieved a balance between production and sales

　　 two 　 Green production 　 Build environmental protection intelligent demonstration factory

　　 In all aspects of textile industry chain, clean and green production is not only the practical needs of enterprises to achieve energy conservation and emission reduction, but also the only way to comprehensively implement scientific development and sustainable development. Many fiber yarn enterprises continue to promote clean production, energy conservation and consumption reduction, improve resource utilization efficiency from the aspects of equipment, technology, products, management, etc., and enhance the intelligent degree of factories through digital empowerment, and solidly promote the construction of green manufacturing system.

　　 In June 2020, Yongrong Jinjiang's first renewable energy pilot project, 8 MW rooftop distributed photovoltaic power generation project, was successfully connected to the grid in Jinjiang plant. At present, the first phase of the project has been completed. It can provide about 8million kwh of renewable power every year, which is equivalent to saving 2520 tons of standard coal, reducing 6000 tons of carbon dioxide emissions and 3.76 tons of sulfur dioxide emissions. Since the grid connected operation, the operation efficiency of the system is as high as 85%. The 120000 square meter plant roof installation photovoltaic project of phase II project is under preparation. It is estimated that the grid connected power generation will be carried out in August 2022, with an annual power generation of 29.25 million kwh, equivalent to saving 9213.8 tons of standard coal, reducing 21900 tons of carbon dioxide emissions and 13.72 tons of sulfur dioxide emissions.

　　 In addition to energy saving and consumption reduction through photovoltaic power generation, Yongrong Jinjiang has also made efforts in many aspects, such as equipment renewal, technical transformation, zero emission in warehousing and logistics, rainwater recovery, etc., and has explored a new path of carbon emission reduction from the operation and consumption side, continuously promoted the R & D and innovation of "three yarns" of Jinkang yarn, Jinsheng yarn and Jinyi yarn, and advocated the implementation of green production and green lifestyle, Provide green products and high quality services to the society. The company's recycled polyamide fiber subverts the traditional source of fiber raw materials, finishing and utilizing waste resources to produce a new type of fiber similar to the original fiber, realizing the unity of green, low-carbon, recycling and high utilization rate.

　　 In order to actively promote the implementation of "carbon peaking and carbon neutralization", Dezhou Huayuan selected the stator plant as a green leading demonstration plant, set a carbon reduction blueprint, took the lead in purchasing green electricity, and signed the SBTI scientific carbon target initiative. In addition, the intelligent high-performance fiber high-end customized production line project under construction in Huayuan, Dezhou, plans to build the only three-tier intelligent and digital "Lighthouse" factory in the textile industry in the province, combining the key development fields such as high-performance new materials, high-end equipment, information technology, Internet +, big data, etc., and is committed to digital management, intelligent production and lean operation, To achieve energy-saving, carbon reduction, clean production, to build China's textile industry differential yarn intelligent low-carbon manufacturing demonstration enterprise.

　　 For energy saving and consumption reduction, Sanyou chemical fiber has formed a complete system from the perspective of water, electricity and steam. On the one hand, we will carry out the technical research on the recovery and reuse of acid wastewater, the deep utilization of F2 water and the recovery and reuse of condensate water, so as to realize the recycling and reuse of water resources and greatly reduce the consumption of water resources; On the other hand, through the research of spinning cutter switching cycle, frequency conversion control of centrifugal pump in acid station, popularization and application of air suspension centrifugal blower, the power consumption of enterprises can be reduced; Research and implement low-quality waste heat reuse technology, dryer efficiency improvement, high-efficiency falling film evaporation process, etc., to promote the reduction of enterprise steam consumption; At the same time, we organized the research and development of projects such as shortening the yellowing cycle time, improving the refining machine efficiency, increasing the production and efficiency of the baler, and continuously improving the single line capacity and reducing the unit energy consumption.

　　 In the process of promoting the "carbon peak, carbon neutral" action, it inevitably increases the operating costs of enterprises, but many enterprises through product research and development, energy conservation and consumption reduction, improve production efficiency and other innovative measures, in order to reduce costs and promote sustainable development of enterprises to a higher level.

　　 three 　 Circulation system 　 Building green ecosystem of industrial chain

　　 He who goes alone is fast, and the others are far away. To promote the goal of "carbon peak and carbon neutralization" is not something that can be achieved by a certain link or an enterprise in the textile industry chain. The upstream and downstream of the industrial chain are required to cooperate closely to realize the pollution-free green development of the whole process from raw materials to products, and establish a green circular ecosystem from the source to the end of the industrial chain.

　　 As Li Yubin, executive vice president of Dezhou Huayuan, said, promoting carbon peak carbon neutralization is not an investment behavior of an enterprise, but requires the cooperation and participation of the whole supply chain. The company hopes to work with upstream and downstream partners to practice green textile and create a beautiful home. Therefore, in 2021, Dezhou Huayuan actively participated in the commitment of "climate innovation 2030 action" and "30.60 China Textile and clothing carbon neutralization and acceleration action" of China Textile Federation, and cooperated with the responsible office of China Textile Association, amo, Lanjing and supply chain enterprises to carry out LCA carbon emission calculation of modal clothing, comprehensively calculate the carbon emission of each process, and display the carbon emission at the consumer end, It promoted the launch of modal carbon footprint products and played a good demonstration effect in the industry.

　　 On the road of green and low-carbon development, Dezhou Huayuan is not alone. More and more enterprises are making unremitting efforts towards the common goal. Shan chuanlei, general manager of Qingdao bond, believes that in order to achieve peak carbon neutralization, we should not only do a good job in the "subtraction" of energy conservation and emission reduction, but also do a good job in the "addition" of clean energy, and promote green and low-carbon development with the concept of ecosystem and industrial chain thinking. Therefore, from product source to product output, through technological innovation and utilization of renewable resources, bond fiber can reduce resource waste, use new technology and new combination to shorten production cycle, stabilize product quality, strengthen cooperation of industrial chain, and promote green sustainable development of textile industry chain.

　　 As one of the first batch of enterprises to join the "30 · 60 China Textile and garment carbon neutralization acceleration action", Sanyou chemical fiber has completed the formulation of double carbon goals: by 2030, the carbon emission per unit product will be reduced by 30%, and by 2055, the carbon neutralization will be achieved; The first sustainable development report of the company was released, and the preparation and publication of the sustainable development report were planned to be carried out annually. The evaluation work of textile life cycle was carried out, and ecotang was completed ® The product life cycle assessment (LCA) disclosed ecotang ® Carbon footprint information. Zhang Dongbin, deputy general manager of the company, said that in the future, the company will increase cooperation with domestic and foreign brands, gradually gather from both ends to the middle, promote the construction of transparent, low-carbon and sustainable industrial chain, and lead the new trend of green consumption.

　　 "The company strictly controls the import of raw materials, adheres to the responsible purchasing policy, comprehensively reviews the forest industry chain and pulp supply chain, and improves the utilization ratio of zero carbon pulp and waste textile pulp. It not only realizes the recycling of raw materials in the region, but also actively promotes the recycling of waste cotton textiles in the textile industry together with the industrial chain partners. At the same time, relying on the regional circular economy of Sanyou group, the company has made great efforts to promote the recycling of waste cotton textiles in the textile industry The closed-loop utilization of matter and multi-level utilization of energy are realized. For example, taking advantage of the group's industrial network, NaOH produced by other subsidiaries can be directly transported to the company through pipelines, so as to reduce the carbon emission generated by transportation. " Zhang Dongbin said.

　　 From the top-level design of policies to the planning and layout of industrial enterprises, China's "double carbon era" was officially opened, giving new connotation, new challenges and new opportunities to the development of enterprises in the textile industry. As the source of textile, the field of fiber yarn has already sounded the "charge" to promote the comprehensive green transformation. More and more enterprises have implemented the dual carbon goal with practical actions, committed to working with industry chain partners, proposing flexible solutions around all aspects of the value chain, jointly creating a closed-loop economy of sustainable development and creating a new era of low-carbon and zero carbon textile.
