光電子 KODENSHI

Recycling resources. Recirculating warmth.

Our guiding concept is circularity. In creating material that helps keep the wearer warm, we came up with ways to optimize limited resources. The result is Re:nsulation.
A batting made with KODENSHI® — our proprietary fiber made from recycled synthetic fiber — Re:nsulation maintains warmth by reflecting far infrared rays that emanate from the body.
By reincarnating synthetic fiber and recycling body heat, Re:nsulation completes a sustainable circle of the Earth’s energy.

FEATURE

Far infrared rays maintain comfortable warmth.
Soft batting that provides exceptional thermal insulation, compressibility and resilience.
Over 90% of all polyester fiber used is recycled.

EVIDENCE

Comparison of thermal images

Using thermography, the performance of a jacket with KODENSHI® Re:nsulation was compared to one with typical synthetic fiber batting. After 20 minutes of wear, the jacket with KODENSHI® Re:nsulation showed a larger heat map of elevated body surface temperature.
