Profile of Divisions

Our division aims to create high-performance fiber materials with ultrafine diameters by leveraging electrospinning technology, and to realize practical applications and social implementation across a wide range of fields, including energy strage, air filtration, water remediation, food packaging, and piezoelectric sensors.

1. Nanofiber for Air Filtration
2. Nanofibers for Energy and Environmental Applications
3. Nanofibers for Food Packaging
4. Nanofibers for Piezoelectric Sensor

Equipped with spinning machines of various sizes and instruments for physical property measurement and structural analysis, we provide the complete workflow from sample fabrication to characterization.

Our research into extreme-environment protective clothing drives breakthrough innovations for everyday sportswear. Through our integrated R&D system--from material development to product evaluation--we partner with industry, academia, and government to create next-generation high-performance clothing systems.

Research on Design and Evaluation Technologies for Textiles and Fiber Products that Meet Kansei Requirements
With the aim of meeting Kansei (Affective/Sensory) requirements--what people perceive as "comfortable" and "preferable"--we conduct integrated research on the design and evaluation of textiles and fiber-related products. We develop methodologies that combine objective measurements with subjective assessments to support evidence-based product development.

1. Performance and Physical Property Evaluation of Textiles
2. Comfort Evaluation of Fiber-Related Products
3. Functionalization and Applications of Textiles
4. Integration with Human Sciences

The fiber based composite materials division at the Institute for fiber engineering and science (IFES), conducts interdisciplinary research on advanced composite materials based on fibers, polymers, and inorganic components, aiming to develop high performance materials that contribute to industrial innovation and a sustainable society.

1. Weight comparison of steel and CFRP plates of the same size: Steel weighs approximately 89 g, while CFRP weighs about 20 g.
2. Physical and chemical activation by introducing surface roughness on carbon fibers
3. Development of a green recycling method for carbon fiber-reinforced composites

This division is conducting research on the development of functional and intelligent fiber assembles through a series of processes, from fibers to yarns and from yarns to woven and knitted fabrics.

We aim to elucidate the ecology of silk production and egg diapause in domesticated and wild silkworms using a multifaceted approach. Additionally, we are investigating the mechanisms of biosynthesis of various biofibers, including domestic and wild silkworm resources, and exploring their potential use as materials in a wide range of fields.

1. Large Antheraea yamamai and Antheraea yamamai in Nagano Prefecture.
2. Bombyx mandarina and Bombyx mori.
3. Suizenji-nori (Aphanothece sacrum) and images of sacran produced by suizenji-nori.
4. Joro spider (Trichonephila clavata) and fibers spun by Joro spiders.
5. Morphologies of cells on the silk fibroin-based material.

The Division of Fundamental Research at the Institute of Fiber Engineering and Science at Shinshu University is a new division dedicated to pursuing academic aspects of fiber science. By integrating bio/soft materials, biometrics, and interface chemistry, the division advances the development of theories and functions to realize next-generation fiber technology.
