Beschreibung
Zusammenfassung:	To provide an artificial fibroin compact enhanced or improved in mechanical properties such as elongation at break (extensibility), toughness, tensile strength, Young's modulus and the like as compared with natural silk, and a method for producing the same.SOLUTION: The present invention relates to a method for producing an artificial fibroin compact in which a liquid containing a natural or artificial fibroin-derived protein is used as a silk doping liquid to produce an artificial fibroin compact from the silk doping liquid, and the present invention provides a method including the steps of forming an amorphous coagulate using a cyclic ether solvent as a coagulation bath or using a solvent containing cyclic ether as a coagulant as the coagulation bath, and post-drawing the amorphous coagulate to thereby crystallize the same, and the artificial fibroin compact produced by the method.SELECTED DRAWING: Figure 7 【課題】天然のシルクと比較して、破断点伸び（延伸性）、靭性、引張強度及びヤング率等の機械的特性が向上又は改善した人工フィブロイン成形体、及び、それらを製造するための方法を提供する。【解決手段】本発明は、天然又は人工のフィブロイン由来タンパク質を含有する溶液をシルクドープ液として、該シルクドープ液から人工フィブロイン成形体を製造する製造方法であって、環状エーテル溶媒を凝固浴として、又は、環状エーテルを凝固剤として含有する溶媒を凝固浴として非晶質凝固体を形成する工程、及び、前記非晶質凝固体を後延伸することにより結晶化させる工程、を含むことを特徴とする、製造方法、及び該製造方法で製造されることを特徴とする、人工フィブロイン成形体を提供する。【選択図】図７
