The New Trend Of Chemical Fiber Industry From The Operation Practice Of Three Green Fiber Certification Enterprises

Green, low-carbon, recycling is an important task for China's chemical fiber industry to achieve sustainable development. This year, three chemical fiber enterprises have passed the green fiber certification, which are Haiyang Technology Co., Ltd. (dope dyed nylon 6 filament), Hubei Botao Synthetic Fiber Co., Ltd. (recycling and reusing raw liquor dyed polypropylene staple fiber and stock liquor dyed polypropylene staple fiber), and Pingdingshan Shenma cord fabric development company (liquid dyed nylon 66 industrial filament). At present, the total number of green fiber certification enterprises has increased to 37.

Green fiber certification can promote the green development process of the whole industry chain from fiber to end products.

What are the characteristics of the products of these three enterprises? How about its application in downstream market? What are their practical feelings in practicing green development? Recently, the reporter interviewed the relevant persons in charge of these enterprises.

　　 Green development is the general trend and important policy

In recent years, the global textile and garment industry has been steadily promoting the green development. Among them, a number of international famous brands have played a leading and exemplary role. Adidas, for example, has announced that it will replace the original polyester fiber with recycled polyester fiber in 2024. IKEA also announced that it will use 100% recycled polyester by 2025.

From China's point of view, "the 14th five year plan" period is the key period and window period for China to implement the concept of green development, actively respond to climate change and achieve the goal of carbon peak.

China Textile Industry Federation has previously issued the "guiding opinions on green development of textile industry during the 14th five year plan" that "textile industry is a responsibility oriented green industry. Establishing and improving the industrial system of green and low-carbon cycle is an important symbol and basic bottom line to realize the high-quality development of the whole industry."“‘ During the 14th Five Year Plan period, under the background of the world's unprecedented great changes and China's construction of a "double cycle" new development pattern, under the guidance of national carbon peak and carbon neutralization goals, it will be the general trend and important policy for the textile industry to promote green and low-carbon circular development and promote the comprehensive green transformation of the industry. "

Green fiber is a kind of chemical fiber with low carbon and environmental protection, which comes from biomass or recyclable materials, and has no pollution to the environment or can be recycled after being discarded. Green fiber certification advocates green design, green materials and green manufacturing of products, which has a conductive and driving role and can promote the green process of the whole industrial chain from fiber to end products.

Li Deli, deputy chief engineer of China Chemical Fiber Industry Association, introduced that the products rated as green fiber must meet the requirements of high standards in raw material procurement, fiber production process, product safety, environmental protection and other fields. For example, resource attributes include water intake per unit product, comprehensive energy consumption per unit product, raw material consumption per unit product, reuse rate of industrial water, and comprehensive utilization rate of waste silk and waste.

Li Deli said: "in the past few years, enterprises with green fiber certification have made continuous improvement in technology and technology. While improving the level of energy conservation and emission reduction, they also actively cultivate downstream users to use green fiber and vigorously advocate green consumption. The industry influence of green fiber logo is constantly improving, which highlights the brand image of green development of chemical fiber industry

In fact, the vigorous development and promotion of green fiber is not only the embodiment of China's chemical fiber industry and textile industry's active practice of green development, but also to make green fiber products with "source green, core green, and product green" fly into ordinary people's homes, and guide and guide the development of green fiber products Promote the whole society to gradually form the fashion trend of "consumption of green fiber products is to contribute to the construction of green water and green mountains".

　　 Certification enterprises firmly practice green development

Green fiber includes three categories: Bio based chemical fiber, recycling chemical fiber and coloring chemical fiber. Among them, the solution dyed chemical fiber includes polyester, nylon, polypropylene and other products.

Haiyang science and technology obtained green fiber certification product is liquid dyed nylon 6 industrial filament. Its product specifications cover 210d-1890d, including red, yellow, green, blue and other color systems, products have been applied to fishing nets, ropes, ribbon, sewing and other fields. The green fiber certification products of Hubei Botao include recycled dyed polypropylene staple fiber (mainly used in automobile interior decoration, carpet, geotextile field) and liquid dyed polypropylene staple fiber (applicable to carpet and other fields). The green fiber certification product of Shenma cord fabric Co., Ltd. this time is original liquid dyed nylon 66 industrial yarn, with specifications ranging from 70D to 2520d. The products are mainly used in automobile wiring harness, sewing thread, military textiles, water cloth and other fields.

Haiyang technology is located in Taizhou City, Jiangsu Province, mainly engaged in nylon 6 chips, nylon filament, nylon cord fabric, has been focusing on the production and research and development of nylon 6 for 50 years, and its total production capacity is 440000 tons / year. The company's R & D and production of nylon 6 chips and nylon cord fabric have strong competitiveness in the domestic market, and its "qiuxue" brand nylon 6 industrial yarn has a high market share in fishing nets, ropes and other fields.

It is reported that in recent years, the company has built a continuous in-situ polymerization nylon 6 chip test platform and "Jiangsu Polyamide Engineering Technology Center" which integrates small-scale test, pilot test and industrialization. The company innovates, develops and produces the colored in-situ polymerized nylon 6 chips with international advanced level, and opens up a new way to dye the original solution.

"This kind of chip can directly spin various colored nylon filaments such as fine denier and ultra-fine denier, and the spun nylon yarn has uniform color, no batch color difference, and higher color fastness than masterbatch spinning. At the same time, it also extends the service life of spinning components and needles, and can provide spinning users with more choices of raw materials. In the second half of 2020, the company's R & D and production of in-situ polymerized nylon 6 Black chips and in-situ polymerized nylon 6 black wires have successfully realized industrialization. In addition, the company also participated in the research and development of bio ginilon 56 based on straw. " The relevant person in charge of the company said.

Based on the production capacity of in-situ polymerized nylon 6 chips at present, if it is used in the processing of garment fabrics or other special nylon 6 fibers, it will save 30% - 50% of the cost compared with the latter dyeing and finishing process, and the medium dark color can save 220 million kwh, 2 million tons of water and 3500 tons of dyes.
