This study focused on the dyeing of glass fibres by colour layers created by the sol gel method. Glass fibres are used as a typical example of fibres with non-ideal dyeing properties. Glass and similar dyes are rigid, the internal fibre structure is non-porous and the glass transition temperature is very high. The sol gel method is used for the fixation of selected dyes on the fibre surface. In this study , we compared basic, disperse and met al complex dyes. The properties of coloured textiles were tested by standard and modified fastness tests. The stability to temperature, washing and light was different according the basic properties of the used dyes. The results of the tests are discussed in this paper. The process of dyeing fibres with sol simultaneously results in reasonable dye fastnesses to the fibres; at the same time, bright and dark shades can also be obtained. The sol used is based on the blending of 3-trimethoxysilyl propyl methacrylate in isoprop anol with supporting chemicals (water , HCl, benzoyl peroxide).
