| Outline of Final Research Achievements |
Silk, which is a renewable resource with excellent mechanical property, is attracting attention from the field of next-generation of structural materials. In order to realize mass production of silk, the creation of artificial silk protein is being promoted all over the world, and therefore the development of its spinning technology is urgently required. The purpose of this study is to develop the artificial spinning technology giving artificial silk fibers with comparable mechanical property with native silks. In this study, first, a detailed structural analysis for various silks was carried out and then the structural formation process was investigated. Finally, an artificial spinning system was developed by mimicking the structural formation mechanism learned from the native silks. The achievements in this study is expected to contribute to accelerate the realize of sustainable society.
