保温性のある羽毛

鳥の羽毛は、一本の軸からV字型の羽枝が両サイドに沢山広がっている構造で、これがたくさん集まることで空気を閉じ込めて保温し、体を暖かく保つ。羽毛はケラチンというタンパク質の一種でできており、寒いところに生息する鳥の羽毛（βケラチン）ほど、より多くの空気を繊維の中に保持することができる。また、βケラチンからなる羽毛は、復元性が非常に高く、体積が増す。

その他

高い保温力を持つ、マイクロファイバーとポリエステルファイバーとで構成された新しい不織布の開発に応用されている。保温力を高めた人工の羽毛を使って、衣料や布団の詰め綿の開発に応用されている。

羽毛を構成するβケラチンの構造を模倣し、羽毛と光量子繊維やポリエステルなどの化学繊維を混合することで、より高機能な人工羽毛の開発に応用できる。ケラチンを培養・抽出して、新しい繊維の開発に応用できる。
