Only Kawada Feathers can make photoelectron® down.
This is the UMOU Science Lab. This is a specialized down laboratory that examines the mixing ratio of down, feathers, and impurities in feathers, as well as the cleanliness and bulk (fill power) of the feathers. Originally a laboratory of Kawada Feathers, it is still attached to the factory, but in order to ensure fair testing, it was established as a separate company in 2015, with stricter shipping standards than those of the International Down and Feather Board (IDFB), and has been recognized as an IDFB certified testing organization since 2018.
Kawada Feathers' feathers are inspected strictly according to its own quality standards. For example, the cleanliness test for feathers requires a passing score that is more than twice the industry standard.
. We were shown processed Photoelectron® down. On the right is Photoelectron® down. All are the same 1 g, but the bulk is different. When the down is refined, it expands, but when it is mixed with Photoelectron® fiber, the weight of the fiber reduces the bulkiness.
Photoelectron® down is completed by kneading rayon fibers with Photoelectron® ceramics and intertwining them with feather twigs. 20% of the photoelectron® fiber is used for the weight of the down, and if more is mixed in, the effect will not change, only the bulkiness will decrease. The size of down that can be intertwined with photoelectron® fiber is limited, and less than 10% of the world's production is suitable for this purpose. The technology to combine down and Photoelectron® fiber was developed by Kawada Feathers, which specializes in processing down for water repellency and fire retardancy, among other things. The technology for kneading in Photoelectron® fiber is a trade secret patented by Kawada Feathers.
I knew that Photoelectron® down was warm, but I didn't understand how it worked. The indigenous people of the Arctic Circle, whom I have visited before, use animal pelts to protect themselves from the cold, and this kind of winter clothing has been around for a long time. I was amazed at how they have combined such natural materials with modern state-of-the-art technology to achieve this level of functionality. I sometimes wait for hours for a photo opportunity in extremely cold weather, but I don't move and wait patiently, so I think that photoelectron® down, which retains heat through body radiation, is better suited for me than materials that heat up through perspiration.
