Award-winning project introduction
Second Prize of National Technology Invention Award
project name:
Creation of Out-of-pipe Falling Film Liquid Phase Viscosity Reactor and New Technology of Solution Straight Spinning Polyester Industrial Silk
The main completed: Chen Wenxing (Zhejiang University), gold leather (Zhejiang ancient defibrillators, New Materials Co., Ltd.), Yan Xuming (Yangzhou Hui Tong Chemical Technology Co., Ltd.), Liu Xiong (Zhejiang ancient defibrillators, New Materials Co., Ltd.), Wang Jianhui (Zhejiang Guxiandao New Material Co., Ltd.), Zhang Xianming (Zhejiang University of Science and Technology)
Achievements: Melt polycondensation to prepare high-viscosity polyester solution is a major technical problem in the polymer industry. Therefore, the production of polyester industrial yarn in the world has long been a three-stage process of melt-polycondensation, solid phase polycondensation, and melt spinning. Side spinning process), this production method has long process flow, large equipment investment and high production energy consumption. At present, green development has become a national strategy, and it is imperative to develop energy-efficient production technologies. For decades, internationally renowned companies have been working on the development of new horizontal stirred reactors for the preparation of industrial grade high viscosity polyester solutions, but have not yet achieved large-scale industrialization. The project abandoned the research and development of horizontal reactors, invented the core equipment and developed the whole process technology through innovative melt polycondensation method, and successfully realized the high efficiency, energy saving, short process and flexible production of polyester industrial yarn.
The project has built the world's largest production capacity and lowest energy consumption of 200,000 tons and 300,000 tons of two solution direct-spinning polyester industrial yarn production line. Compared with the slice spinning production line, it saves 420 million yuan in equipment investment and shortens the process flow by more than 30 hours. The project has reached the international leading level and is an original technological breakthrough in the polyester industry.

Key technologies and industrialization of ramie eco-efficient textile processing
Main completed units: Hunan Huasheng Group Corporation, Donghua University, Hunan Agricultural University
Main Completions: Cheng Longzhen, Rong Jinlian, Xiao Qunfeng, Li Yuling, Yan, Chen Jiwu, Jie Yucheng, Yan Guixiang, Qi Ying, Cui Yunhua
Achievements: Ramie is a special fiber resource in China. Its output accounts for more than 90% of the world. It has the characteristics of high strength, low elongation, moisture absorption, moisture permeability and quick drying. It has natural anti-mildew, anti-ultraviolet and other functions. It is a high-quality natural product. Cellulose fiber.
The ramie industry has a long history. The current development dilemma is long process flow, low labor productivity, low added value of products, and serious homogenization competition. The main reason is that ramie has high rubber content, coarse fiber, high crystallinity and large dispersion, which causes large degumming pollution and serious yarn hairiness. It is difficult to produce pure spinning and light fabric, and the fabric has low dyeing fastness, strong itching and easy wrinkling, which restricts The development of castor industry. The project has carried out systematic research and development in the fields of ramie planting, degumming, spinning, weaving, dyeing and finishing, and developed eco-efficient biochemical one-step degumming technology, smooth spinning technology, high-efficiency weaving technology, dyeing and finishing technology, and cultivated high A new variety of low-density ramie.
The average yarn unit price of the technical application unit of the project increased by 45%, and the unit price of the fabric increased by 60%. Eco-efficient energy saving achieved good results, production efficiency, product quality greatly enhance, promote technological progress ramie textile.
project name:
Key technology and industrialization of fully automatic computerized flat knitting machine equipment supporting industrial internet
Main completed units: Zhejiang Normal University, Ningbo Cixing Co., Ltd., Gutech (Shenzhen) Co., Ltd.
Main Completions: Zhu Xinzhong, Sun Pingfan, Li Lijun, Lu Shu, Zhao Jianmin, Wu Qiliang, Xu Huiying, Hu Yueyong, Gong Xiaoyun, Liu Yue
Achievements: For a long time, the knitting flat knitting machine market has been monopolized by foreign brands such as Shimadzu, Germany and Stoll, which seriously restricts and hinders the development of China from a large knitting country to a strong country, and realizes the localization and autonomy of fully automatic computerized knitting machine equipment. There is no time to delay. The development of domestically produced models not only faces high-speed and stable operation, elimination of bottom waste yarn, smooth weaving, precise coordinated control and knitted fabric simulation, automatic identification, machine networking and other major technical problems, but also must face foreign patent technical barriers. The project started from breaking through the protection of foreign patent technology and overcoming the key and major problems of the common industry, breaking the technological monopoly of developed countries, mainly focusing on the key technology and industrialization of automatic computerized knitting machine, and grasping and mastering the automatic bottoming weaving, high-quality complex pattern knitting, high-speed knit organization, knitted fabrics and knitted fabric simulation automatically identifies, multi-sensor data fusion technology and intelligent control strategies intelligent manufacturing industry Internet integration technology, the full realization of a new automatic computerized flat knitting machine Localized, comprehensive performance has reached the international advanced level. The project's achievements have successfully replaced imports , breaking the long-term monopoly of foreign counterparts and promoting the technological advancement of the knitting industry.
project name:
Key technologies and industrialization of dry polyimide preparation
Main completed units: Donghua University, Jiangsu Aoshen New Materials Co., Ltd.
Main Completions: Zhang Qinghua, Wang Shihua, Zhan Yongzhen, Chen Dajun, Tao Mingdong, Guo Tao, Dong Jie, Zhao Wei, Miao Ling, Chen Bin
Results: As a typical high-performance fiber, polyimide (PI) fiber not only has excellent mechanical properties, but also has excellent heat resistance and radiation resistance, making the fiber in space exploration, high temperature, radiation and other harsh The environment has a greater advantage than other polymer fibers and is one of the most urgent materials in the country. PI fiber was first commercialized by the Austrian company Lenzing, and it has been in a monopoly for a long time. Therefore, it is imperative to realize the localization of PI fiber.
At present, the production of PI fibers at home and abroad adopts the wet spinning technology route, which has problems such as long production process, large energy consumption for solvent recovery, and environmental pollution. In order to improve the performance of the product and the greening of the production process, the project proposed a new method of "reactive spinning" for PI fiber dry spinning, breaking through a series of key technical bottlenecks in fiber preparation, and realizing the fiber preparation process and The technical integration of the equipment has built the world's first dry PI fiber 1000-ton production line.
Compared with the international level, the PI fiber produced by the project has increased the fracture strength by 10%, the temperature stability has increased by 100 °C, and the raw material cost is 1/3 of the former. This product has been successfully used as a high-temperature filter material, which plays an important role in the treatment of atmospheric pollution such as PM10 and PM2.5 generated by industries such as coal burning and cement production. The product is also used in fire protection clothing, tactical missile internal insulation layer, radome, nuclear facility protection and other fields, which has effectively promoted the leap-forward development of China's high-performance fiber industry.
