Focus on fiber greening to help achieve the goal of "double carbon"

China Net finance July 13 news (reporter Cao Zhongyuan) Chemical fiber industry as the cornerstone of China's textile industry, the scale of growth, innovation and development, the status is crucial. In recent years, as a leading enterprise in the fiber industry, Xinxiang Chemical Fiber Co., LTD. (hereinafter referred to as Xinxiang Chemical Fiber) has proposed to build a vision of "the leader of China's green textile industry" and "the pioneer of China's green textile industry ecosystem", centering on the development strategy of "strengthening the main industry and extending the industry", constantly increasing scientific and technological innovation, focusing on fiber manufacturing, and continuing to develop competitive industries. In order to promote the high-quality development of China's chemical fiber industry and help the realization of the national "double carbon" goal, a steady stream of "egret" power is injected.

China.org.cn: High-quality development cannot be achieved without scientific and technological innovation. How is your company's performance in industrial innovation, especially in scientific and technological innovation?

Xinxiang Chemical Fiber: The company adheres to "innovation leadership, digital empowerment, green transformation", takes independent innovation ability as the core competitiveness of the enterprise, and the intensity of technological transformation and project research and development investment has increased year by year. In 2022, the company carried out 50 research and development projects, and invested 460 million yuan in research and development, and added 62 new authorized utility model patents throughout the year. Make good use of five research and development platforms, such as the Bailu New Materials Research Institute, postdoctoral research workstation, and Henan Chemical Fiber Engineering Technology Research Center, committed to creating the "birthplace" of fiber key core technologies, the "gathering place" of green innovation resources, and the "booster" of scientific research achievements transformation, so that the leading ability of recycled cellulose filament and spandex industries will continue to improve.

Xinxiang Chemical Fiber through technological innovation to achieve production iteration upgrade, the company has developed and has independent intellectual property rights of the new continuous spinning machine, with a number of innovative results and core technology, efficiency increased by more than 30%. The production capacity and equipment level of the company's continuous spinning recycled cellulose filament are among the top in the world. Xinxiang Chemical Fiber and Zhengzhou COSCO cooperation research and development of high-efficiency spandex fiber production line, won the first prize of China Textile Science and Technology Progress, spandex core technology and equipment with high consistency spandex polymer technology and equipment, the use of near infrared online monitoring, advanced control system (APC) control polymer molecular weight and molecular weight distribution, It can meet the different requirements on the aggregation structure of spandex fiber in dyeing, shaping and post-processing of weaving. The spinning technology adopts high-density spinning and high-speed winding technology, and the spinning speed can reach 1000m/min or more. It has the advantages of "waste recycling" and "gas centralized treatment", and the waste recycling efficiency is 99%.

With the goal of "single equipment automation, intelligent production line, intelligent comprehensive management", Xinxiang Chemical Fiber has carried out strategic cooperation with China Mobile, China Electronics, Shanghai Jiaotong University and other units to actively promote the company's intelligent digital construction.

China.org.cn: At present, China's cellulose fiber raw materials are highly dependent on imports, which poses a potential threat to industrial safety. What preparations or measures does your company have in terms of import substitution?

Xinxiang Chemical fiber: With the decline of the world economic situation, prominent resource problems and the introduction of the national 3060 plan, enhancing the safety level of the industrial chain has become a topic of concern for the whole industry. Xinxiang Chemical fiber continues to explore the full green product production system, is committed to non-wood raw materials bio-based fiber exploration and research, has carried out bamboo, bamboo willow, straw and other pulping research, 2022, Xinxiang chemical fiber will focus on the fungal grass technology inventor Lin Zhanxi research, fungal grass cellulose content is high, is the ideal non-wood fiber raw materials, Xinxiang Chemical Fiber carried out the first research on the green textile technology and comprehensive utilization of fungus, mastered the full set of technology from a grass to a silk, and declared a number of invention patents such as fungus pulp and fungus fiber. At the same time, it combined with Dalian Institute of Chemical Compounds of Chinese Academy of Sciences to carry out comprehensive utilization of three elements to realize the industrial application of the whole body.
