The world's first use of cellulose nanofiber compo

  • Detail

For the first time in the world, cellulose nanofiber composites are used to make new sports shoes

the weight of cellulose nanofiber (CNF) extracted from wood fiber is one fifth of that of steel, but its strength is five times that of the latter. In Japan, CNF has been active in research and development for many years and has achieved significant results

nedo's research results and starlight PMC's cellulose nanofiber CNF composite starce have been applied to the production of the latest sports shoes to enhance the core competitiveness of the industry. Starcel is a CNF reinforcing resin material and manufacturing process developed by a joint group of industrial schools with Kyoto University as the main body in the development project of NEDO. It was developed by starlight PMC in February, but how to use the metallographic polishing machine 0. The Oak Ridge National Laboratory team needs to solve several problems: is it a material that can overcome the diversity of lignin raw materials and start commercial production in January, 2018. The latest sports shoe "gel-kayano 25" of ASICs has a part of the middle layer of the sole, which not only proves that it has the scratch resistance that the original material scheme can not meet, but also adopts this material. It is the first time in the world that CNF has been used to make shoes and sold worldwide

asics' gel kayano 25 sneakers use cellulose nanofibers to improve the performance of runners

cellulose nanofibers (CNF) are light-weight nanofiber materials with high strength and low thermal expansion derived from woody plants, which are expected to be used as resin reinforced fibers. NEDO has researched and developed CNF reinforced resin material and manufacturing process. The specific method is to chemically treat the wood pulp first, then melt the modified cellulose with polyethylene (PE) or polypropylene (PP) and other resins, and finally manufacture according to the manufacturing process of nanofibers. Based on the development of NEDO, starlight PMC has successfully completed the commercialization of CNF composite materials through independent improvement, and started commercial production under the brand of "starcel" in january2018. "Starcel" has excellent characteristics such as high strength and not easy to generate thermal expansion

gel-kayano series is a favorite running shoe of track and field athletes in the past 25 years. The middle layer of the sole of gel-kayano 25 adopts the lightweight and cushioning foam Lyte, which contains the CNF composite "starcel"
