On August 15, 2025, the grand opening of the new generation champion version running shoe launch event of Xtep was held. Professor Wu Dezhen, Chairman of Jiangsu Xiannuo New Material Technology Co., Ltd., was invited as an important partner of Xtep to attend the launch event and talked about the core product of Xiannuo New Material, Shinofil ® The connection between high-performance polyimide fibers and Xtep's golden carbon board has witnessed another major breakthrough in the field of running shoes together with Xtep.
Twenty years of sharpening a sword: Shino silk from laboratory to space
20 years ago, high-performance polyimide fibers departed from the High Performance Polymer Research Laboratory at Beijing University of Chemical Technology. Academic leader Professor Wu Dezhen led a team to devote themselves to scientific and technological research, and finally achieved a breakthrough in small-scale experiments. In order to transform experimental results, Jiangsu Shino New Material Technology Co., Ltd. emerged in 2013, embarking on a difficult and long journey of innovation and entrepreneurship.
Nowadays, Shino New Materials has successfully achieved large-scale preparation of high-performance polyimide fiber series products, with multiple production lines including filament, short cutting, weaving, and pre soaking. The products cover long fibers, short fibers, fabrics, pre impregnated materials, ropes, belts, threads, and flocs, with two major production bases established, covering a total area of 55000 square meters and a total production capacity of nearly 1000 tons.
Shino New Materials' core product Shino silk Shinofil ® The comprehensive performance of high-performance polyimide fibers is extremely excellent, with outstanding mechanical, high and low temperature resistance, aging resistance, low water absorption, low dielectric, high insulation, natural antibacterial and other performance characteristics. The technology is innovative and internationally leading.
At the beginning of development, Shino silk Shinofil ® Fiber is mainly aimed at the aerospace industry. The aerospace environment is complex and harsh, and there is an urgent need for high-performance organic fibers. After years of rigorous verification, Shino silk Shinofil ® Fiber, with its excellent performance, has been successfully applied in aerospace fields such as satellites, rockets, deep space probes, and airplanes, providing strong material support for the development of China's aerospace industry.
The dilemma of market expansion: aerospace materials with high complexity and limited resources
Although Shino silk Shinofil ® Fiber has made significant achievements in the aerospace field, but it faces numerous challenges in the process of market expansion. Due to Shino silk Shinofil ® Fiber is a new material with low market awareness, and in the absence of application cases, there is a fear of using it in the market. Meanwhile, due to the lack of application of Shino silk Shinofil ® There is a problem of not knowing how to effectively apply the experience and technology of fibers into products. Even if some customers try to use it, it may not be possible to fully utilize Shino silk Shinofil due to process, equipment, and other reasons ® The performance advantages of fibers may lead to poor performance.
Turning point: A handshake of "daring to be the first, a thousand promises"
Both Xtep and Shino New Materials share the common philosophy of "daring to be the first", daring to try new technologies and materials, and actively seeking breakthroughs. This concept has become a solid foundation for cooperation between both parties. Xtep takes the lead in using Shino silk Shinofil ® Fiber is introduced into the field of professional running shoes in order to break through the limits of running shoes. With a strong R&D team as the backing and close cooperation with Xtep, Shinofil has successfully achieved the production of Shino silk ® Breakthrough in the application of fibers in the field of sports.
The Scientific Magic of Golden Carbon Plate:
When Shino silk Shinofil ® Fiber meets carbon fiber
The mystery of balance between toughness and toughness
By using Shino silk Shinofil ® The composite layer of fibers and carbon fibers fully utilizes the synergistic effect of the two fibers, giving the golden carbon board excellent performance advantages. In terms of stiffness and toughness, Shino silk Shinofil ® Fibers have strong and tough properties, while carbon fibers have strong and rigid properties. The combination of the two perfectly balances the stiffness and toughness of carbon sheets. This allows the carbon plate to provide stable support for running shoes while also having good flexibility. During running, it can better adapt to changes in foot movement, reduce discomfort caused by the carbon plate being too hard or too soft, and provide runners with a more comfortable and efficient running experience.
In terms of impact performance, ordinary carbon plates are prone to brittle fracture when subjected to large external forces, while Shino wire Shinofil ® The addition of fibers greatly improves this situation. Shino silk Shinofil ® The super strong impact resistance of the fiber effectively improves the impact performance of the carbon board, enabling it to maintain structural integrity and prevent damage when facing various impacts during running, thereby extending the service life of the carbon board and providing more reliable protection for the safety of runners.
Lightweight Revolution
In terms of weight, Shino silk Shinofil ® The specific gravity of fibers is 20% lower than that of carbon fibers, which makes gold carbon boards lighter in weight while ensuring structural strength. A lighter carbon plate can reduce the overall weight of running shoes, reduce the burden on runners during running, make it easier for runners to run, and improve running efficiency. Especially in long-distance running, the advantages of this lightweight design are more obvious, which can effectively reduce runners' fatigue and help them maintain a better state.
The future is here: the infinite possibilities of Chinese materials
Looking ahead to the future, Shino New Materials will continue to uphold the spirit of innovation and continuously enhance its technological strength and professional capabilities. We are well aware that in the era of rapid technological development, only through continuous innovation can we stand invincible in the fierce market competition. We will increase investment in the research and development of high-performance fibers, continuously optimize product performance, explore more new application areas, and provide better and more efficient material solutions for Xtep and other partners.
We also believe that with the joint efforts of numerous enterprises and researchers, China's new material technology will continue to make breakthroughs, shine brighter on the global scientific and technological stage, and make greater contributions to promoting the high-quality development of our country's economy and society.
