New Materials: New Generation Graphene Textile Thermal Insulation Materials Application Release

"One generation of materials, one generation of equipment, one generation of industry". Since the discovery of graphene, its downstream new energy, electronic information, big health, energy and chemical industrial applications have gradually broken through, and the blue ocean of thermal conductive film, lubricating oil, lithium-ion battery additives and other markets have followed. With the continuous development of graphene preparation and dispersion technology, textile fiber is expected to become a new breakthrough in the large-scale application of graphene. China's textile industry is undergoing a deep transformation from made in China to "intelligent manufacturing" in China, from resource allocation to innovation driven. The industry needs high quality and brand development. New materials represented by graphene have become an important starting point for the transformation and upgrading of the textile industry.

On January 16, the graphene Industry Development Forum 2020 and the launching ceremony of 100 enterprises entering Baoshan jointly sponsored by cgia and Shanghai graphene industry technology functional platform were held in Shanghai, The R & D team led by Wang Jinmei, Professor of the new textile materials and Industrial Application Research Institute of the alliance, released a new generation of graphene textile thermal insulation materials.

? ? ? The high-quality graphene material prepared by three-level oxidation method is combined with nano far-infrared, phase change microcapsules and aerogel materials independently developed. Aiming at the problems of poor thermal insulation performance, heavy weight, poor thermal and wet comfort, no microbial protection and serious electrostatic phenomenon of traditional thermal insulation materials, the composite spinning technology was used to develop graphene thermal insulation down like polypropylene There are three kinds of products: fiber olefin warm wool, hollow graphene polypropylene insulation fiber olefin warm cotton, graphene hollow super thermal insulation viscose fiber olefin soft cotton. The results show that the physical and mechanical properties of all kinds of graphene textile insulation fibers prepared by this material are excellent. The far-infrared emissivity is 88%, the heat retention rate is 85.3%, the anti-static property is up to a grade, and the antibacterial rate is higher than 96% after 50 times of washing.

Market recognition is the key to the promotion of advanced technology products. In the face of the heat preservation needs of garrison training and field exploration, the R & D team focused on opening up the fiber to clothing industry chain, and trial produced all kinds of thermal insulation down jacket, thermal underwear, thermal socks and other cold resistant products. Among them, the cold proof clothing used in PetroChina Qinghai Oilfield has passed the trial verification, and the products have excellent cost performance, and 100000 sets of purchase orders have been obtained. It is reported that experts have commented that the product technology has not been reported in the same category at home and abroad, reaching the international advanced level; the downstream products have been verified by end customers and have good social and economic benefits; it is suggested to further develop the market and accelerate the large-scale popularization and application.

? ? ? The Institute of graphene textile new materials and industrial application is a strategic alliance of technological innovation of graphene industry. It integrates the upstream and downstream resources of graphene textile application at home and abroad. It is committed to the development of new graphene textile materials and new technologies, promotes the transformation and application of scientific and technological achievements, cultivates scientific and technological talents in relevant fields for enterprises, and promotes the sustainable development of graphene textile new materials and industrial applications. The Research Institute will also build a platform for the application and promotion of graphene in the textile field, and form the collaborative development of innovation chain, industrial chain and capital chain, so as to provide strong support for expanding the market application of graphene in the textile field.
