Abstract. In this paper, a method of obtaining hydrophobic colored coatings on cotton fabric using colloidal Sol-gel fixation technique is described. The aim of this work is studying of properties of cotton fabric with hydrophobic colored silica coating and researching of dependency of properties of the materials on technological parameters as well as the influence of precursor concentrations, hydrolysis catalyst and temperature. The test of the obtained materials was carried out using the methods of measuring the tensile strength, wetting angle by the method of photographing the applied drops, and raster electron microscopy was used to prove the possibility of obtaining a sol-gel coating by the two-way method. In the course of the experiments it was proved that the increasing of temperature of heat treatment and the concentration of the precursor yields to an increase in the adhesion of the hydrophobic coating to the substrate. Results of this search can be used in design of combined technology of dyeing and special finishing of textile materials
