Abstract
The present invention relates to a process for spinning silk fibers. The process involves dissolving silk fibroin in an aqueous salt solution, removing the salt from the solution, followed by removal of the water to form a regenerated silk material. The silk material is then dissolved in hexafluoroisopropanol to form a fiber-spinnable solution.
