Looking at the new trends in the chemical fiber industry from the operating practices of three green fiber certified companies
Green, low-carbon and recycling are important tasks for the current sustainable development of my country’s chemical fiber industry. This year, three chemical fiber companies have newly passed the green fiber certification, namely Haiyang Technology Co., Ltd. (dope coloringnylon6 filament) and Hubei Botao Synthetic Fiber Co., Ltd. (Recycling of dope-dyed polypropylene staple fiber, dope-dyed polypropylene staple fiber), and Pingdingshan Shenma Cord Fabric Development Company (dope-dyed nylon 66 industrial filament). At present, the total number of companies that have obtained green fiber certification has increased to 37.
Green fiber certification can promote the green development process of the entire industry chain from fiber to end products.
What are the characteristics of the products of these three companies? How about its application in downstream markets? What are their practical feelings about practicing green development? Recently, reporters from China Textile News interviewed relevant persons in charge of these companies.
Green development is the general trend and an important strategy
The global textile and apparel industry has firmly promoted green development in waves in recent years. Among them, a group of internationally renowned brands have taken the lead and demonstrated. For example, Adidas has announced that it will replace all virgin polyester fibers with recycled polyester fibers in 2024. IKEA also announced that it will use 100% recycled polyester by 2025.
From our country’s perspective, the “14th Five-Year Plan” period is a critical and window period for our country to practice the concept of green development, actively respond to climate change, and achieve its carbon peak goal.
The China Textile Industry Federation previously issued the “Guiding Opinions on Green Development of the Textile Industry during the 14th Five-Year Plan”, stating: “The textile industry is a responsibility-oriented green industry. Establishing and improving a green and low-carbon recycling industrial system is an important symbol and basic bottom line for achieving highquality development of the entire industry.” “During the ’14th Five-Year Plan’ period, the world has experienced a century-old In the context of unprecedented changes and my country’s construction of a new development pattern of “dual cycle”, under the guidance of the national carbon peak and carbon neutrality goals, it will become the general trend and important for the textile industry to promote green and low-carbon cycle development and promote the industry’s comprehensive green transformation. strategy.”
Green fiber refers to raw materials derived from biomass or recyclable materials. The production process is low-carbon and environmentally friendly. The finished product does not pollute the environment or can be recycled after disposal. Utilized chemical fibers. Green fiber certification advocates green design, green materials and green manufacturing of products. It has a conductive and driving role and can promote the green process of the entire industry chain from fiber to end products.
Li Deli, deputy chief engineer of the China Chemical Fiber Industry Association, said that products rated as green fiber must meet high standards in raw material procurement, fiber production process, product safety, environmental protection and other fields. For example, resource attributes involve multiple subdivisions: water intake per unit product, comprehensive energy consumption per unit product, raw material consumption per unit product, industrial water reuse rate, and comprehensive utilization rate of waste silk and waste materials.
Li Deli introduced: “In the past few years, companies that have obtained green fiber certification have continued to improve their processes and technologies. While energy conservation and emission reduction consumption reduction levels have continued to improve, It also actively cultivates downstream users to use green fiber and vigorously advocates green consumption. The industry influence of the green fiber logo continues to increase, highlighting the brand image of green development in the chemical fiber industry.”
In fact, vigorously developing and promoting green fiber is not only a reflection of my country’s chemical fiber industry and textile industry actively practicing green development, but also an attempt to make green fiber products with “green source, green core, and green product” more widely available. “Flying into ordinary people’s homes” guides and promotes the whole society to gradually form a fashion trend of “consuming green fiber products is to contribute to the construction of green waters and green mountains”.
Certified enterprises firmly practice green development
Green fibers include three categories: bio-based chemical fibers, recycled chemical fibers and solution-dyed chemical fibers. Among them, solution-dyed chemical fibers include solution-dyed polyester, nylon, polypropylene and other products.
Haiyang Technology’s product that received green fiber certification this time is solution-dyed nylon 6 industrial filament. Its product specifications cover 210D to 1890D, including red, yellow, green, blue and other colors. The products have been applied to many fields such as fishing nets, ropes, ribbons, and sewing processing. Hubei Botao’s products that have obtained green fiber certification this time include recycled dope-dyed polypropylene staple fiber (mainly used in automotive interiors, carpets, geotextile fields) and dope-dyed Polypropylene short fiber (can be used in carpets and other fields). Shenma Cord Fabric Company’s product that has obtained green fiber certification this time is solution-dyed nylon 66 industrial yarn, with specifications ranging from 70D to 2520D. The products are mainly used in automotive wiring harnesses, sewing threads, military textiles, water cloth and other fields.
Haiyang Technology is located in Taizhou City, Jiangsu Province. It specializes in nylon 6 chips, nylon filament, and nylon cord fabric. It has focused on the production and research and development of nylon 6 for 50 years. Currently, its totalThe production capacity is 440,000 tons/year. The nylon 6 chips and nylon cord fabrics developed and produced by the company are highly competitive in the domestic market, and its “Qiuxue” brand nylon 6 industrial yarn has a high market share in fishing nets, ropes and other fields.
According to reports, in recent years, the company has built a continuous in-situ polymerization nylon 6 slice test platform and the “Jiangsu Polyamide Engineering Technology Center” that integrates small-scale testing, pilot testing, and industrialization. The company has innovatively developed and produced internationally advanced colored in-situ polymerized nylon 6 slices, opening up a new way of liquid coloring.
“This kind of chip can directly spin various colored nylon yarns such as fine denier and ultra-fine denier. The spun nylon yarn has a uniform color, no batch color difference, and a higher color fastness than masterbatch spinning. At the same time, it also has It extends the service life of spinning components and knitting needles, and can provide spinning users with more raw material selection options. In the second half of 2020, the company developed and produced in-situ polymerized nylon 6 black slices and in-situ polymerized nylon 6 black silk smoothly. Industrialization has been achieved. In addition, the company has also participated in the research and development of bio-based nylon 56 using straw as raw material.” said the relevant person in charge of the company.
Based on its current production capacity of 20,000 tons/year of in-situ polymerized nylon 6 chips, if used for the processing of garment fabrics or other special nylon 6 fibers, it will It saves 30% to 50% of the cost compared to back-end dyeing and finishing. Medium-dark colors can save 220 million degrees of electricity, 2 million tons of water, and 3,500 tons of dyes.
