Recently, several studies have been conducted on the use of optical fibers in the field of photonic technologies. In fact, photonic applications have been developed for various functions including entertainment, communications, and safety protection. However, studies on the applications of flexible optical fiber to smart photonic clothing and luminescence effects are few. The present paper reports on the optimum condition of luminescence effects and the uniform surface through a experimental study of plastic optical fiber(POF)-based flexible textile using different methods of weaving and electronic packaging focused on the red right. For this purpose, we first assessed the differences in the luminance values based on whether etching of the POF-based flexible textile was done and on whether a reflective fabric backing was used. We also analyzed the difference between the luminance values with and without an optical lens on the light source.
