China's graphene modified fiber world leads the development of new world of textile and garment industry

China Economic Net·Economic Daily August 30 (Reporter Shan Baojiang) Tang Yilin, chairman of Jinan Shengquan Group Co., Ltd., took the test bulb and placed its positive and negative poles on a shirt. The light bulb is on.

This shows that the fabric of the shirt is electrically conductive. This seemingly ordinary shirt is made of graphene modified fiber fabric.

This is a scene witnessed by reporters in the interview of Shengquan Group at the end of August.

Don't underestimate this conductivity, gas stations, gas stations, and some special workplaces, static sparks can bring disaster. Put on such clothing, static electricity will no longer be harmful.

Like rare earth materials, many metal and non-metal materials have magical functions. After adding a small amount of graphene to ordinary fibers, many novel functions are also produced. This is the graphene modified fiber. The graphene modified fiber produced by Shengquan Group has been identified by experts and has the functions of far infrared, long-lasting antibacterial, antistatic, anti-ultraviolet, moisture absorbing and breathable. These functions have opened up a vast space for imagination in the textile and garment industry and opened up a new world of development. Vice president of China Textile Industry Association, China Chemical Fiber Industry Association president ends Xiaoping said graphene market prospects, not only have a significant impact on the chemical fiber textile industry, for the industry will bring more attractive change.

Many countries in the world have been eyeing this magical new field. Some developed countries have included graphene modified fiber in the national science and technology development strategy and increased research and development efforts. China has surpassed the curve in this field, and later came to the fore, and the industrialization development has taken the lead in the world.

Graphene is the most disruptive new material in the 21st century and has been heated up in recent years. According to reports, at present, most of the international use of chemical methods to synthesize graphene, its single source of raw materials, high pollution and other issues have become the industry threshold. Fu Honggang, the president of Heilongjiang University, led the research team and Shengquan Group to form a unique strategy. The world's first corncobose cellulose was used as raw material to prepare graphene by thermal cracking. The whole production process is green and environmentally friendly , and the source of raw materials is mainly agricultural waste. With this as a symbol, bio-based graphene new materials were first born in the world and realized large-scale production. The word "bio-based" is popular in that the new material comes from biological raw materials such as plant straw. This is an amazing innovation and revolutionary discovery. It opens up low-cost, large-scale, green manufacturing of graphene materials. The new era.

Continued efforts, Shengquan Group and Donghua University, Qingdao University, Heilongjiang University jointly undertake the "bio-based graphene macro-preparation and the industrial application of graphene in functional fibers" project, successfully developed graphene surface modification and polymer dispersion techniques to solve the graphene regenerated cellulose fibers, polyester staple fiber and nylon 6 spinning process agglomerates easily, is difficult to control the quality and other issues, the development of graphite-modified fibers from spinning to weaving and dyeing Through the series of technical systems such as textile molding processing. Currently, Quan Group has an annual output of 200 tons of bio-based material graphene production lines and an annual output of 2000 tons of graphene functional polymer masterbatch production lines, research and development in the production of bio-based Graphene has independent intellectual property rights of fiber warm, warm inside Three series of velvet and internal heating olefin pore materials, more than 100 single products, has become the world's first enterprise to realize the industrial production and commercial utilization of graphene. Tang Yilin introduced that the technology has been applied for 105 national patents and 12 international patents.

Watching the product display of Shengquan Group, the reporter is excited. The graphene-modified textile products are rich and colorful. Technician holding instruments, these new product features to verify on the spot reported data. The reporter once participated in a meeting of the Shengquan Group. Academician Yao Mu, an expert on textile materials in China, said that in 1998, hundreds of thousands of PLA soldiers who participated in the flood fighting and rescue operations had problems of foot erosion and femoral sulcus erosion. At that time, I had been sleepy for this. Academician Yao Mu lamented that if there were graphene modified fibers at that time, how wonderful! ”

By utilizing the characteristics of graphene-modified fibers, it is possible to produce clothes that are light, thin and warm. In the winter, the ladies can show their slim body, and the frontier soldiers can lightly climb and lie in the snow without feeling cold. Using its antibacterial properties to produce socks, people who have stinky feet can no longer be paralyzed.

In June of this year, the China National Textile and Apparel Federation organized the appraisal and acceptance committee of Sun Jinliang and Jiang Shicheng, two academicians, to appraisal and acceptance of this scientific and technological achievement. The appraisal committee unanimously agreed that the project invented a new method for preparing graphene materials using corncob cellulose as raw material... Developed a series of high-efficiency spinning technology for graphene modified fibers, weaving and dyeing and finishing technology, and established graphene functional textiles. Molding processing technology system; established a production line with an annual output of 200 tons of bio-based graphene materials and an annual output of 2000 tons of graphene functional polymer masterbatch production line, with reasonable process, complete equipment and stable production operation. The graphene powder masterbatch has good spinnability and imparts long-infrared, antibacterial, antistatic and anti-UV functions. The project has independent intellectual property rights and has broad application prospects in the fields of clothing, home textiles and light industry. Significant economic and social benefits, the overall technology has reached the international advanced level, the appraisal committee unanimously agreed to pass the appraisal.

This project has broken through a lot of technical difficulties. For example, graphene powder has a "collective" effect like magnetic powder of aragonite, and it is difficult to uniformly add it to the fiber. They worked together with universities to make graphite fine powder evenly distributed in the fiber. With its strong technical advantages, Shengquan Group has become the leader in China's graphene modified fiber industry.

On August 17, the Ministry of Industry and Information Technology announced a letter supporting the establishment of a graphene modified fiber and application development industry development alliance. It expressed support for Jinan Shengquan Group to take the lead and unite the relevant units in the industrial chain to jointly break through the constraints of graphene. The “bottleneck” of the application and promotion of modified fiber, making it stronger and stronger, and improving the graphene modified fiber and application development.

Innovation, taking the path that no one has ever walked, the Shengquan Group has been questioned and even ridiculed. Tang Yilin told reporters that even after the identification of the graphene modified fiber technology of Shengquan Group, these doubts and ridicule did not calm down. Many people do not believe that such tall materials will be produced from cellulose in corn cobs. Some people also took the data on the books to laugh at the fact that the graphene modified fiber of Shengquan Group could not achieve the theoretical ideal purity.

The technical staff of Shengquan Group told reporters that textile fabrics with an emissivity of over 88% can be said to have far-infrared function. Fabric emissivity after Quan Group joined biomass graphene as high as 91% -92%. The far-infrared of this band has many benefits for the human body. Every new function of graphene modified fiber has been rigorously tested and verified to win trust with accurate data.

Tang Yilin told reporters that enterprises pay more attention to the market value of graphene modified fiber, and pay more attention to the benefits it brings to consumers. The support of the Ministry of Industry and Information Technology has added confidence to the Shengquan Group and has also boosted the rapid development of graphene-modified fibers in China.

According to reports, Shengquan Group can produce one ton of graphene with 15 tons of corncob. The total amount of corn cobs in China is as high as 100 million tons per year. A large amount of corn cobs are used as fuel as waste and even wasted. Shengquan Group uses corncob cellulose as raw material to prepare graphene, which opens up a new way for the corncob to use efficiently and increase farmers' income.

Tang Yilin said that the research and development of graphene modified fiber has been at the forefront of the international market, with bright prospects and a promising future. However, in this field, no experience of the predecessors can be used for reference. Every step is pioneered in the blank space of the ancients. The uncertainty is great, the difficulties are many, the challenges are severe, and it is difficult for a few enterprises and research institutions to form a strong propulsion force. . The Ministry of Industry and Information Technology supports the establishment of the China Graphene Modified Fiber Alliance by Shengquan Group. We will use the open mind to gather the resource advantages of the industrial chain, accelerate the innovation, research and development and application promotion, and make China a global highland of graphene modified fiber as soon as possible.
