Single micro-yarn with good mechanical properties that elute different drugs and proteins. This is one combination made possible with this new technology. Several strands of nanofibers each with its own unique property or function can be drawn together to form a single micro-yarn. The production of yarn is continuous and its length is only limited by the amount of raw materials available.
Distinct advantages
- Possibility of fabricating single yarn containing nanofibers with different property
- Able to spin continuous yarn
- Fibers that formed the yarn are well aligned
- Great variety of polymers that can be used
Materials that have been successfully spun into yarn
Biodegradable:
- PLGA
- PCL
- PCL/collagen blend
- PLA/collagen blend
Non-biodegradable:

Current rate of production : 80 m/min
Possible applications
- Suture
- Ligament replacement
- High performance / functional fabric
Status
Looking for commercial partners to further develop current technology
