羽毛の酵素処理及び木質繊維の軽度の補強による羽毛樹脂の物性変化

Abstract

The waste chicken feathers were treated with the enzymes (dissociating disulfide bonds) produced by thermophilic Meiothermus ruber H328, and then the treated feathers were milled and subjected to the hot-press compression molding. It was found that the recrystallization of the feather keratin was interfered with to some extent due to the lack of S-S bonds. On the other hand, the slight reinforcement of the feather resin with the wood fibers was effective to enhance the tensile behavior and the thermal stability of the feather resin.
