In our previous work, we have produced a photochromic wool fabric by applying a thinlayer of hybrid silica-photochromic dye onto the wool surface. The coating showed a very fastoptical response, but had little influence on the fabric handle, however durability was low. In thiscontext, we reported that durability of the hybrid layer can be improved by introducing epoxygroups into the silica matrix via co-hydrolysis and co-condensation of an alkyl trialkoxysilane(ATAS) and 3-glycidoxypropyltrimethoxysilane (GPTMS). The presence of epoxy groups in thesilica enhanced both washing and abrasion durabilities. Also, the optical response speed wasslightly increased as well. Effects of the type of alkyl silane and the GPTMS:alkyl silane ratio onthe coating durability, fabric handle and optical response were examined
