“…Common POF core materials are amorphous polymers like PMMA, PS, PCs or COPs, with PMMA having the lowest attenuation [ 66 , 69 ]. Based on their relatively low refractive index, fluoropolymers are typically utilized as cladding material [ 216 ].…”

“…The relatively low processing temperatures even enable doping with luminescent dyes, which enables illuminating and light harvesting applications [ 220 ]. Despite their relatively high attenuation, POFs can be advantageous in textile applications where only short-distance light delivery, but high flexibility and good processability are required [ 216 ]. Apart from signal transmission and illumination, POFs also find applications in sensing, where the electronic equipment can be kept at a remote place free of electromagnetic noise [ 221 ].…”

Textiles have a very long history, but they are far from becoming outdated. They gain new importance in technical applications, and man-made fibers are at the center of this ongoing innovation. The development of high-tech textiles relies on enhancements of fiber raw materials and processing techniques. Today, melt spinning of polymers is the most commonly used method for manufacturing commercial fibers, due to the simplicity of the production line, high spinning velocities, low production cost and environmental friendliness. Topics covered in this review are established and novel polymers, additives and processes used in melt spinning. In addition, fundamental questions regarding fiber morphologies, structure-property relationships, as well as flow and draw instabilities are addressed. Multicomponent melt-spinning, where several functionalities can be combined in one fiber, is also discussed. Finally, textile applications and melt-spun fiber specialties are presented, which emphasize how ongoing research efforts keep the high value of fibers and textiles alive.

Polymer optical fibers (POFs), including side‐emitting POF (SEPOF) and end‐emitting POF (EEPOF) are developed for luminous textiles. The SEPOF is more common for usage but suffers from significant intensity decay, which limits its effective usage length. In contrast, the EEPOF can provide a much more stable side illumination behavior than SEPOF since the light is largely confined within the EEPOF, while its side illumination requires special treatment. In this work, 0.5 mm diameter EEPOFs were firstly assembled into bundles with 10 EEPOFs (B10) and 15 EEPOFs (B15), and then twisted. The morphology, tensile properties, and side illumination behavior of the twisted EEPOF bundles are evaluated. With an increased twisting degree, the initial modulus of twisted sample B10 increases (due to shortening of bundle diameter) from 1.06 to 1.17 GPa while the initial modulus of twisted sample B15 decreases from 1.01 to 0.91 GPa. The increased twisting degree also results in the higher flexibility (indirectly connected with modulus) of the twisted EEPOF bundles. Besides, the increased twisting degree results in a higher side illumination intensity meantime causes a decreased side illumination intensity along the light penetration path. When the twisting degree is low (e.g., 10 T m−1), the highest decrease rate of side illumination intensity along the light penetration path is found.
