11Advanced Textile EngineeringManufacturing high-performance synthetic fiber by controlling fiber structure formationDepartment of Advanced Textile and Kansei EngineeringSpinning and drawing are the most fundamental processes in manufacturing synthetic fiber. In my lab, we produce many types of bicomponent fibers, including sheath/core and sea/island variants, using a bicomponent melt-spinning apparatus and investigate the fiber structure formation process on spinning and drawing lines. This research has broad application in fields such medicine and transportation.Associate Professor Kim graduated from the Department of Textile Engineering at Pusan National University of South Korea. He currently serves as an assistant professor at the Innovative Cooperation Center in the Faculty of Textile Science and Technology at Shinshu University and as a patent examiner in the Korean Intellectual Patent Oce. His elds of research include melt spinning and analysis of the ne structure of ber, textiles, and lms.Fibers made of bicomponent spinningHigh-strength bers for tire cordElectron micrograph of multi-hollow polyester berElectron micrograph of sea/island berSchematic diagram of a bicomponent spinning machineBy controlling ber structure through a detailed on-line analysis of the ber structure formation process, it is possible to extend elds of application to high-performance tire cord (use as a reinforcement) and high-tenacity hollow ber (a medical use).Outlook for researchGraduates who understand the fundamentals of the ne structure of bers and possess knowledge ranging from the fundamentals to applications are able to work in any part of the textile industry.Outlook for students after graduationwinder spin block hopper hopper heating guide 1 2 3 heating guide !3 2 1 gear pump extruder heating chamber Transestrification in interface Nozzle structure core sheath sheath interface steel tire cordpolyestertire cordbead wiretire cordKyoungHou KimAssociate ProfessorAdvanced Textile EngineeringDepartment of Advanced Textile and Kansei EngineeringI am working on sen’i from the standpoint of textile engineering and textile science. In the case of the former, I am investigating textile machines and systems. As for the latter, I my goal is to discover the laws that lie dormant in sen’i. Humans have acquired various materials, and sen’i have been used for a long time as clothing. Why must clothing be sen’i? I believe that this is a mystery worth unraveling.Akio SakaguchiAssistant ProfessorMeasuring ber gures in card webs.There are also rules in spun silk thread hand-crafted from oss silk.Born in the city of Ueda in Nagano Prefecture, Assistant Professor Sakaguchi graduated from the Faculty of Textile Science and Technology at Shinshu University but left without completing Shinshu University Graduate School’s textile engineering program. He worked as a research associate in the Faculty of Textile Science and Technology at Shinshu University before taking his current position. His current area of specialization is textile engineering.Long ago, there were many large and small printing shops, but computers and printers have completely changed the world of printing. Today, the culture of printing has developed to the point that anyone can print various materials in their own homes. Growth of industry and elevation of culture are not equal. Will similar developments occur in the world of sen’i?Outlook for researchEven if equipped with engines of the same power, a racecar and bulldozer excel at completely dierent jobs. What is important is not the question of which is superior, but the fact that they can combine their respective specialties.Outlook for students after graduationThinking about the future of sen’i (the Japanese word for fibers and textiles) in Japan
