This research demonstrates enhanced UV protection and self-cleaning in knitted polyester fabrics using TiO2 and fluorescent agents.
This paper has investigated the development of sustainable textiles for architectural applications using TiO2 nanoparticles and fluorescent whitening agents on knitted polyester fabrics. The implementation of TiO2 improved photocatalytic self-cleaning and UV protection properties of fabric, while the addition of fluorescent whitening agents enhanced fabric whiteness and optical appeal, while optimizing the UV blocking effect. The enzymatic pretreatment of polyester fabric increased hydrophilicity, ensuring uniform deposition of TiO2 nanoparticles and improved the functional properties. The self-cleaning performance tested by degradation of blackcurrant dye under UV/VIS light showed up to 79 % stain removal after 2 hours, confirming the photocatalytic efficacy of TiO2-treated fabrics. The obtained results show the potential of modified polyester fabrics as multifunctional materials for sustainable architecture, offering high UV protection, improved aesthetics and enhanced self-care. These textiles are suitable for use in tensioned structures, shading systems and building façades, contributing to energy efficiency, durability and sustainability. Additionally, the possible applications of such knitted functionalized fabrics as textile patterns in architectural environments are presented and visualized by artificial intelligence (Leonardo.Ai) based on sketches and photos of the design author (T. Frasonski).
