Summary:A strong and even side illuminating effect is required for plastic optical fibers (POFs) in illuminating applications. In consideration of good flexibility and illumination, side emitting POFs with 2 and 3 mm core diameters are preferred, especially in active illuminating safety textiles. However, the side illumination intensity of side emitting POF varies significantly along the fiber length. Fluorescent polyester (PET) fabric rather than traditional surface modifications is employed to enhance and even the side illuminating effect of POFs based on the emitting principle of phosphors. Two testing methods of side illumination intensity are carried out on semi-automatic devices. The results indicate that 2 mm side emitting POFs might take the place of 3 mm side emitting POFs by using fluorescent PET fabric, with a similar side illuminating effect in applications under certain circumstances.
