Abstract

Different silica hybrid film forming materials were obtained and deposited on polyester fabrics and their optical and thermal properties have been investigated. Structural characteristics of network modifying agents determined vicinities of the embedded or chemically grafted nonionic dyestuffs and decisively influenced the optical behavior of the hybrid coatings. By modifying the hybrid materials using specific organic groups it is possible to tailor adhesion forces between the coating and textile substrate and thus can be determined fastnesses to wash and light of the colored coatings. Thermogravimetric analysis revealed the flame retardant effect manifested by the hybrid silica films deposited on polyester fabrics..
