“…Different from the continuous decrease in luminance of the reference sample with the direction of light propagation, side illuminance along propagation direction was firstly increased and then decreased in etched case. By comparison, the side illumination behavior of the etched POFincorporated PET fabric is not only different from the reference sample, but also very different from the results of existing studies including single POFs (both SEPOFs and EEPOFs) ) [19] and other combined POFS [20]. Correspondingly, part 1 for increase of side illumination intensity and part 2 for decrease of side illumination intensity were specified, respectively.…”

The textile industry has been weaving polymer optical fibers (POFs) into plane fabric for many years for lighting and decoration. To apply POF-incorporated fabrics in a larger field of application, it is necessary to improve the side illumination of POF-incorporated fabrics. It has been reported that the chemical etching method is one method to enhance the illumination of POFs, while there is little research related to the application of chemical etching to enhance the illumination of POF-incorporated fabrics. In this work, the end emitting POFs (EEPOFs) were used as weft yarns, and polyethylene terephthalate (PET) yarns were used as warp yarns. The POF-incorporated woven PET fabrics were successfully fabricated with a 1/3 twill structure and then treated with a mixture of acetone and methanol (volume ratio: 1:1) for 1 min. The morphology and side illumination of etched POF-incorporated PET fabrics were investigated. As a result, the acetone/methanol mixture destroyed the cladding layer of EEPOFs, and the luminance of etched POF-incorporated PET fabrics was increased by more than 50 %. Besides, acetone/methanol etching resulted in a higher side illumination attenuation behavior.
