In this research a beneficial effect of combination of two functional trialkoksysilanes was presented, i.e. oil repellent 1H,1H,2H,2H-perfluorooctyltriethoxysilane and water repellent diureapropyltriethoxysilane (bis(aminopropyl)-terminated polydimethylsiloxane which were applied on the cotton fabric by the sol-gel technology. The nanocomposite polymer film formed on the fibre surface provided washing resistant superhydrophobic and oleophobic properties with a long lasting passive antibacterial activity as a result of the decreased fibre surface free energy.

Modern sol-gel antimicrobial finishing was prepared on the cotton fabric with the use of silver chloride (AgCl) of different concentrations embedded into a silica matrix. The antimicrobial activity of AgCl was assessed before and after repetitive washing for the bacterium E. coli and fungi A. niger and C. globusum. The values of minimum bactericidal and fungicidal concentrations revealed that AgCl was more effective for bacteria than for fungi and that the efficient antibacterial activity of AgCl after repetitive washing could be provided only if applied at the sufficient concentration.

New approaches for evaluating the colour effect of optical mixing of bicolour woven structures composed of constant colour in warp and different colours in weft direction are presented. Changes of fabrics colour properties were achieved by altering their constructional parameters. By developing of geometrical model and additive method, theoretical predictions of the final effect of bicoloured combinations were established and corrected by regression equations, determined from the mathematical relation between the linear-theoretical and the spectrophotometrical colour values.

A reactive dye and nanosilver were applied on the PA6 micro knitted fabric by the exhaustion method. It was found out that the presence of silver changes the colour of the fabric, increases the light fastness of dyeing, but it doesn´t change essentially the value of UPF. Shrinking caused by the dyeing process and the adsorption of the reactive dye are the main reasons for the increased UPF value of the knitted fabric. The presence of nanosilver provided excellent antibacterial properties against Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli.

The cotton fibers were treated with enzymes pectinases and bleached in different one-step and two-step processes with peroxyacetic acid. The result of new processes was the achievement of high quality fibres at lower consumption of water and energy in shorter time and at lower effluent charging in comparison to conventional processes of cotton pretreatment, i.e. alkaline scouring and bleaching with hydrogen peroxide.
