Ten years of sharpening a sword
From the laboratory to mass production
As Marx said, there is no smooth road in science, only hard work. Only those who climb the steep mountain road can hope to reach the glorious summit. The research group of Professor Gao Chao of Zhejiang University first published an article on the in-situ polymerization of graphene and nylon 6 in 2010, which has since opened the road to exploration and practice of graphene composite fibers. Afterwards, Gao Chao founded Gaoyen Technology and worked hard to promote the progress of industry, academia and research through patent transfer from Zhejiang University and the company's own research and development. From basic research in the laboratory to engineering, to commercial mass production, and to the terminal market, Professor Gao Chao led Polyene Technology to stand at the forefront, overcome difficulties, and overcome the long road of research and development.
Along the way, Gaoene Technology has made breakthroughs in high-quality macro-preparation of single-layer graphene oxide, stable preparation of single-layer graphene oxide powder, and single-layer graphene powder through continuous technical research and process optimization. There are dozens of key technologies such as bulk expansion in-situ polymerization technology, uniform dispersion, and high-speed spinning of graphene composite fibers. In 2019, Gaoene Technology's single-layer graphene oxide production line was successfully commissioned and can now achieve an annual production scale of 10 tons. At the same time, based on the stable mass production of graphene raw materials with a single layer rate of up to 99%, Gaoene Technology has broken through the core mass production technology of graphene multifunctional composite fibers and developed graphene nylon, polyester, spandex, acrylic, and viscose. , modal and other series of functional composite fibers.
“Graphene slurry with a single layer rate of 99% can achieve many functions with only one thousandth of the added amount, and will not adversely affect the feel, strength, toughness and other properties of the fiber. Impact. From a technical perspective, in-situ polymerization is different from ordinary mixing and doping. During use, graphene will not be separated from the fiber, ensuring the durability of the product's function, its own safety and environmental friendliness. sex,” said Han Yi, deputy manager of the High-Tech R&D Center.
According to Wang Yang, general manager of Gaocene Technology, Gaocene Technology is currently the first company in the world to obtain IGCC single-layer graphene oxide product certification. Using single-layer graphene oxide as its self-produced core raw material, Gaoene Technology has produced graphene-modified composite fibers through in-situ polymerization and melt spinning. It has also become the world's first single-layer graphene oxide modified functional fiber to pass IGCC certification. enterprises, demonstrating the power of China's textile technology.
Diversified functions
Protecting healthy life with technology
2020 is the final year of the country’s “13th Five-Year Plan” Healthy China Plan, and is also the year to build a moderately prosperous society in all respects A critical year for society. People's livelihood and health are the most important. Without universal health, there will be no comprehensive moderate prosperity. This year's nationwide epidemic has further given "Healthy China" new connotation and significance. The graphene multifunctional composite fiber launched by Gaoene is based on people's health, has its own health protection function, and does not contain heavy metals. It has passed the most stringent safety and environmental protection test of the European OEKO-TEX Standard 100 Textile Confidence 100 Appendix 6, and is suitable for infants. Textiles for children.
"Our graphene multifunctional composite fiber can not only enhance cell vitality, improve immunity, and delay aging inwardly, but also inhibit the growth of viruses, bacteria, mites, and shield ultraviolet rays outwardly. It is a multi-pronged approach. Collaborative care and comprehensive protection of health are ideal textile fabrics for home, sports, business and leisure.
Such functional fiber textiles can also be widely used in public activity areas such as hospitals, hotels, leisure and entertainment venues, schools, high-speed rails, airplanes, automobiles, etc., which can achieve automatic and efficient virus sterilization, antibacterial and antibacterial, and greatly reduce cross-infection. Risk, opening up a new era of health care textiles. "Wang Yang said.
Since this year, in order to cater to consumers' demand for healthy textiles, Gaoyen Technology has actively promoted supply-side reforms, based on raw materials, moving towards terminals, creating new demands with new supplies, and launching ethylene The Phoenix brand's first product, the single-layer graphene multifunctional socks, has received a lot of praise since its launch. The soon-to-be-launched graphene far-infrared light moxibustion blanket has far-infrared life light waves that can promote blood circulation, strengthen metabolism, and achieve improvement. It has multiple functions such as sleeping, relieving fatigue, repelling cold and keeping warm, especially for shoulders, neck, spine, waist and abdomen, joints and other parts. Next, single-layer graphene can protect underwear, fitness clothes, body shaping clothes, etc. Silk towels, vinyl quilts, etc. will also be launched one after another, leading a new lifestyle of "wearing and sleeping for health"
At present, the main contradiction in our society is the people's growing needs for a better life and imbalance. The contradiction between adequate development. Under the new pattern of "internal circulation" and promoting domestic circulation, the textile industry must adhere to the main line of supply-side structural reform, improve the quality and level of the supply system, and create new supply. New needs to meet people's better lives. The diversified functional integration of graphene multifunctional composite fibers provides better choices for people's better lives through technological innovation.
Integrated industrial chain
< p>Join hands with upstream and downstream for joint developmentA person who walks alone will be slow, but a group of people will travel far. In order to promote the rapid development of the graphene multifunctional composite fiber industry, Gaoyen Technology is committed to creating a win-win chain that benefits all parties. and value chain, based on single-layer graphene oxide raw materials, effectively connecting fiber, yarn partners, fabric partners and downstream brand customers, leading the collaborative innovation of the industry chain from the source, and winning the future.
To this end. , Gaoene Technology took the lead in establishing the Graphene Multifunctional Composite Fiber Integrated Research Institute (GCI), and joined hands with Beijing Graphene Research Institute Co., Ltd., Xiamen University Graphene Engineering and Industry Research Institute, and Shenzhen Graphene Innovation Center Co., Ltd. Dozens of other industry chain organizations have opened a new era of cooperation and win-win. The purpose of GCI is to integrate the superior talents, technologies and resources of the industry chain around the construction of the "graphene multifunctional composite fiber" industry system to improve product innovation. As the core, guided by market demand, integrating innovative elements and resource elements such as "government, industry, academia and research funds", we will build the institute into an authoritative community in the field of global graphene functional fibers and promote the development of community members. Innovation, entrepreneurship and sustainable development help make a country strong in fiber, materials, manufacturing and technology.
According to Wang Yang, the company is currently planning to build a 100-ton production line and strives to reduce production costs through capacity expansion. It is planned that in 8-10 years, high-ene graphene multifunctional composite fibers will become the standard in the fiber field, and terminal textiles with built-in health care functions will enter the homes of ordinary people. "Although we are also currently extending the industrial chain. , build our own brand, but our ultimate goal is to achieve C2B. Through the launch of finished products, downstream enterprises and consumer markets can truly experience the health and rehabilitation effects of graphene multifunctional composite fiber products, thus driving the expansion of B-end customers. , after it is widely used in the market, we will shrink our front line and focus on the research and development and production expansion of raw materials."
From the extension of the industrial chain to the contraction of the industrial chain, this may be a long process, but Wang Yang said that the core technology of single-layer graphene oxide from the source to the end product is independently developed by the Chinese. With independent intellectual property rights, it is a model for China's textile technology to lead the world. Gaoyen Technology will not forget its original intention, adhere to the research and development concept of "initiation, ultimate, and mission", starting from people's health, and taking the realization of corporate value and social responsibility as its own responsibility. Use practical actions to interpret the industry's ambition to serve the country, protect people's better lives, and help the high-quality development of the textile industry.
