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

•  Potential uses for spider silk:

•  High performance fabrics

•  Medical applications

•  Cosmetics

•  Advanced coatings

•  Surface treatments

•  Optical enhancement

•  Bioadhesive materials

•  Advanced composites

•  Lightweight and strong yarns and ropes

 

Competitive Advantages

•  Improved mechanical properties

•  Tunable spinning apparatus that enables production of fibers with specific mechanical properties

•  Spinning apparatus contains microscopic video feedback to enable real-time fiber analysis
