Advanced Functional Fabrics of America (AFFOA) fibers integrated into knits. These fibers are drawn as optical fibers with embedded semiconductor diodes.
Each sample tests the limitations of new iterations of LED fibers. At their size of ~400 micron, care and unique tensioning is required.
Failure mechanisms of the fibers can found by knitting with the LEDs powered by a battery. Most notable failures involve bending radius of fibers, tensile strength, and fiber buckling due to cross section geometry.
Results are used to guide fiber development teams in iterating designs.
