The application of photochromism in textiles has potential to create new opportunities to develop fancy colour-changing effects in fashionable textiles, as well as smart garments capable of protecting wearers from the effects of UV irradiation and responding to environmental changes. This book presents a coating method for achieving quick and obvious photochromic effects on wool fabrics using conventional photochromic dyes and hybrid silicas. It covers details about fabricating different types of photochromic dye-silica coatings, measuring their optical performance, assessing some physical characterisations of the coatings, and measuring the effects of the coatings on fabric performance.
