He assumed his current position in 2025. He has won nine awards, including three “Best Paper” awards from the Society of Heating, Air-Conditioning and Sanitary Engineers of Japan (2001, 2004, and 2009) and one“ Best Paper” award from ASHRAE HVAC&R Research (2014).Cross section photograph of multi porous fiber.Ifthestructurecanbecontrolledthroughresearchtodeterminethefiberstructureformationprocess,thefieldsinwhichfiberscanbeusedasindustrialmaterialstirereinforcementandhollowfibersforhigh-strengthfilterscanbefurtherexpanded.Inaddition,recentresearchhasrevealedthatthestructureofnonwovenfabriccanbequantitativelyevaluatedbyusingXCT.Ifyouunderstandthebasicsandunderstandfromthefinestructureoffibers,youwillbeabletounderstandthebasicsandapplicationsregardlessofwhereyouworkinthetextileindustry.This human subject experiment is being carried out to validate the cooling clothing that my lab developed. The clothing provided an adequate cooling effect, even in a warm and humid environment, when a convection fan was simultaneously used.This device is used to determine the heat transfer characteristics of body segments in a non-uniform thermal environment.analysisofBasedontheresultsofandthethermophysiologicalstateintendtoenvironment,surroundingtoformareasonablewaysproposethearoundcomfortablemicroclimatehumanbody,especiallybyadjustingclothingandairflow.Asanexample,mylabhasdevelopedclothingwithadjustablecoolingcapabilitythatutilizeswaterevaporation.textileAftertheDepartmentofTextileEngineeringatBusanNationalUniversityandworkingatKoreapatentexamineroftheKoreaPatentOffice,hebecameanassociateprofessorattheFacultyofTextileScienceandTechnologyinShinshuUniversity,andtookthecurrentpositionin2019.Researchfieldsincludefiber/filmmoldingandnonwovenstructuralanalysisScanning Electron microscope image of sea/island fiberInthesyntheticfibermanufacturingmethod,themostbasicprocessisaspinninganddrawingprocess.Inthislaboratory,weproducevariouscompositefiberssuchascore-sheathtypecompositefibersandsea-islandfibersusingaspinningmachineforcompositefibers,andinvestigatethefiberstructureformationprocessofthecompositefibersonthespinninglineandduringthedrawingprocess.Furthermore,since2014,wehavebeenchallengingresearchappliedtotheanalysisofnonwovenfabricstructuresusingmicroX-rayCT.Bythismethod,theinternalstructureoftheneedlepunchandmeltblownnonwovenfabricwasvisualizednondestructively,andtherelationshipbetweenthefibervolumefractionandfiberorientationinthecrosssectionandthephysicalpropertieswasquantitativelyevaluated.Heating,ventilation,air-conditioning,andrefrigeration(HVAC&R)systemsconsumeenergy.Sincethethermalenvironmentisanimportantfactorindeterminingtheproductivityofoccupants,itisdesirabletodevelopeffectiveHVAC&Rsystems.Iamworkingtodevelopnumericalsimulationmethodsandexperimentaldevicestoanalyzethethermophysiologicalstateofthehumanbodyandthesurroundingthermalenvironment.Simultaneously,IamdevelopingnewpersonalHVAC&Rsystemsbasedonvariousmethodsanddevices.die to collector distanceMelt-blown bicomponent spinning deviceVisualization of nonwoven fabric internal structure by XCT measurementCross-sectional photograph of sheath /core bicomponent fibers.high-performancesuchasfromgraduatingOutlook for researchOutlook for students after graduationOutlook for researchOutlook for students after graduationGraduatesworkformajorhomebuilders,insurancecompanies,partmanufacturingdevelopmentcompanies,companies.andProfessorKIMKyoung-HouProfessorSAKOITomonoriDepartment of �����Advanced Textile andKanseiEngineeringDepartment of �����Advanced Textile andKanseiEngineeringManufacturing of High Performance fibers for protecting of the environment and human healthThe science of heat and thermal perception:Creating individually preferred thermalenvironments by adjusting airflow and clothing
