摘要
The rheological properties of fibroin silk solutions extracted from the middle division of Bombyx mori silkworms were examined. Acidification of the solutions with acetic acid vapor gelled the material, a process which at short time scales could be reversed by exposure to ammonia vapor. The solution could also be converted to sol from the gel state by the addition of EDTA. The possible mechanisms for gel formation in fibroin solutions is discussed as are the implications for the process of spinning silk fibers.
