全球首个千吨级离子液体纺丝项目投产

Core Viewpoint - The successful launch of the world's first thousand-ton ion liquid method regenerated cellulose fiber project marks a significant breakthrough in green fiber technology, achieving zero emissions of waste and a solvent recovery rate exceeding 99% [1][2]. Group 1: Project Overview - The project, located in the Baijun Biobased New Materials Industrial Park of Xinxiang Chemical Fiber Co., Ltd., has an annual production capacity of 1,000 tons of regenerated cellulose fiber using the ion liquid method [1]. - The project utilizes a full-process technology developed by Academician Zhang Suojiang's team, which addresses various technological challenges over a decade, including ion liquid design, cellulose dissolution mechanisms, and spinning processes [1][2]. Group 2: Environmental Impact - The ion liquid method completely eliminates reliance on strong acids and bases, as well as the environmental issues associated with waste gas and wastewater emissions, setting a new benchmark for sustainable development in the regenerated cellulose fiber industry [2]. - The project is seen as a significant contribution to achieving the "dual carbon" goals of the country, enhancing the global green competitiveness of China's textile industry [2]. Group 3: Future Prospects - Plans are underway for a ten-thousand-ton production line, indicating the project's potential for further scaling and market application [2]. - The project is expected to lead to increased market preference for the new fiber due to its superior performance and environmental benefits, driving a trend towards green consumption [2].
