Xiamen graphene invention patent

Hangzhou Gaoene Technology Co., Ltd., as one of the leading enterprises in the field of graphene, first introduced graphene multifunctional composite fibers and products with single-layer graphene oxide as the core material at Yarne Expo autumn and winter yarn exhibition in 2020, which quickly attracted great attention from the industry. Single-layer graphene multifunctional composite fiber has six functions: anti-bacterial, anti-virus, far-infrared internal heating, negative ion generation, anti-ultraviolet and anti-mite. All indicators far exceed the national standards, fully meet the demand of people for healthy textiles in the post-epidemic era, and take the lead in filling the market gap in this field internationally.

A sword takes ten years to form.

From laboratory to mass production

As Marx said, there is no royal road to science, and only those who climb along steep mountain roads without fear of difficulties can hope to reach its glorious peak. The research group of Professor Gao Chao of Zhejiang University published the article of in-situ polymerization of graphene and nylon 6 for the first time on 20 10, which opened the way for the exploration and practice of graphene composite fiber. Later, Gao Chao founded Gao En Science and Technology, and vigorously promoted the progress of Industry-University-Research through the patent transfer of Zhejiang University and the company's own research and development. From laboratory basic research to engineering, to commercial mass production, to the terminal market, Professor Gao Chao led High-olefin Technology to stand at the forefront, overcome difficulties and break through the long road of research and development.

Along the way, Gaoene Technology has broken through dozens of key technologies such as high-quality macro preparation of single-layer graphene oxide, stable preparation of single-layer graphene oxide powder, in-situ polymerization technology of single-layer graphene powder, uniform dispersion of graphene composite fiber and high-speed spinning through continuous technical research and process optimization. In 20 19, the high-tech single-layer graphene oxide production line was successfully debugged, and now the annual production scale can be 10 ton. At the same time, on the basis of stable mass production of graphene raw materials with monolayer ratio as high as 99%, Gaoene Technology broke through the core mass production technology of graphene multifunctional composite fibers, and developed a series of functional composite fibers such as graphene nylon, polyester, spandex, acrylic fiber, viscose and modal.

"Graphene slurry with a single layer ratio of 99% can achieve many functions with only one thousandth addition, and it will not adversely affect the touch, strength and toughness of the fiber. From a technical point of view, in-situ polymerization is different from ordinary mixing and doping. In the process of use, graphene will not be lost from the fiber, ensuring the durability of the product function, its own safety and environmental protection. " Xie Han, deputy manager of Hi-Tech R&D Center, said.

According to Wang Yang, general manager of Hi-Tech, Hi-Tech is the first company in the world to obtain IGCC graphene oxide product certification. With single-layer graphene oxide as the self-produced core raw material, Gaogong made graphene modified composite fiber through in-situ polymerization and melt spinning, becoming the first enterprise in the world to pass IGCC certification for single-layer graphene oxide modified functional fiber, demonstrating the scientific and technological strength of China Textile.

Diversified function

Escort healthy life with science and technology

2020 is the closing year of the 13th Five-Year Plan for Healthy China, and it is also a crucial year for building a well-off society in an all-round way. People's livelihood is the best. Without national health, there will be no overall well-off society. This year's national war epidemic has further endowed "healthy China" with new connotation and significance. Graphene multifunctional composite fiber with high olefin content has health care function and does not contain heavy metals. It has passed the most stringent safety and environmental protection test in Appendix 6 of European OEKO-TEX standard 100 textile confidence 100, and is suitable for infant textiles.

"Our graphene multifunctional composite fiber can not only enhance cell vitality, enhance immunity, delay aging, but also inhibit the growth of viruses, bacteria and mites, shield ultraviolet rays, take a multi-pronged approach, coordinate nursing and protect health in all directions. It is an ideal textile fabric for home, sports, business and leisure. This functional fiber textile can also be widely used in hospitals, hotels, places of leisure and entertainment, schools, high-speed rail, airplanes, automobiles and other public activities. It can achieve automatic and efficient anti-virus, antibacterial and bacteriostatic, greatly reduce the risk of cross-infection, and open a new era of nursing textiles. " Wang Yang said.

Since the beginning of this year, in order to cater to consumers' demand for healthy textiles, Gaogong has actively promoted the supply-side reform, based on raw materials, went to the terminal, and created new demand with new supply, and launched the first product of olefin Phoenix brand-single-layer graphene multifunctional socks, which won many praises once it came out. The upcoming graphene far-infrared light moxibustion blanket, whose far-infrared life light wave can promote blood circulation, strengthen metabolism, and achieve multiple effects such as improving sleep, relieving fatigue, dispelling cold and keeping warm, especially suitable for shoulder and neck, spine, waist and abdomen, joints and other parts. Next are single-layer graphene underwear, fitness clothes, body shaping clothes, vinyl towels, vinyl quilts and so on. It will also be available one after another, leading a new lifestyle of "wearing and sleeping".

At present, the main contradiction in our society is the contradiction between the people's growing need for a better life and the unbalanced development. Under the new pattern of "internal circulation", the textile industry must adhere to the main line of supply-side structural reform, improve the quality and level of supply system, create new demand with new supply, and meet people's better life. Graphene multifunctional composite fiber has diversified functions, which provides better choices for people's better life through scientific and technological innovation.

Integrate industrial chain

Hand in hand with upstream and downstream linkage development

Lonely travelers are ill, and many travelers are far away. In order to promote the rapid development of graphene multifunctional composite fiber industry, High-Tech is committed to building multiple interest chains and value chains, effectively connecting fibers, yarn partners, fabric partners and downstream brand customers based on single-layer graphene oxide raw materials, and leading the industrial chain to collaborate and innovate from the source to win the future.

To this end, High-Tech took the lead in establishing the Graphene Multifunctional Composite Fiber Research Institute (GCI), and joined dozens of industrial chain institutions such as Beijing Graphene Research Institute Co., Ltd., Xiamen University Graphene Engineering and Industry Research Institute and Shenzhen Graphene Innovation Center Co., Ltd. to win a new era. The purpose of GCI is to build the industrial system of "Graphene Multifunctional Composite Fiber", integrate the superior talents, technologies and resources in the industrial chain, take the promotion of product innovation as the core, take the market demand as the guidance, and integrate innovative elements and resource elements such as "Industry-University-Research's investment", so as to build the Institute into an authoritative entity in the field of graphene functional fiber in the world, promote the innovation, entrepreneurship and sustainable development of * * entity members, and help the fiber.

According to Wang Yang, the company is currently planning to build a100t production line, striving to reduce production costs through capacity expansion, and plans to make high-olefin graphene multifunctional composite fiber a standard in the fiber field within 8- 10 years, so that terminal textiles with health care functions can enter the homes of ordinary people. "At present, although we are also extending the industrial chain and building our own brand, our ultimate goal is to achieve C2B. Through the introduction of finished products, downstream enterprises and consumer markets can truly appreciate the health care and rehabilitation effects brought by graphene multifunctional composite fiber products, thus driving the expansion of B-end customers. After the market is widely used, we will shrink the front line and focus on the research and development and expansion of raw materials. "

It may be a long process from the extension of industrial chain to the contraction of industrial chain. However, Wang Yang said that the core technology of single-layer graphene oxide from the source to the final product was independently developed by China people, with independent intellectual property rights. It is a model of China's leading textile technology in the world. High-tech Do not forget your initiative mind adheres to the research and development concept of "initiative, perfection and mission", takes human health as its own responsibility and interprets it with practical actions.
