Apparatus for Synthetic Spider Silk Fiber Formation

Technical Summary

•  Dr. Randy Lewis and his team at Utah State University developed a method and apparatus for producing stronger spider silk fibers through a specialized spinning and stretching process.

•  By manipulating a USU-developed stretching and bathing mechanism, spider silk fibers gain improved tensile strength and elongation properties. Adjustments within the process allow a user to have full control over the final properties of the fibers.

•  In addition, new recombinant spider silk protein (rSSP) combination ratios exhibit substantially improved mechanical properties when produced using the new spinning apparatus and methods.


Commercial Applications
