ABSTRACT

Endowing textile materials with antimicrobial properties aims to achieve two main goals: protection of the material from the effects of microorganisms and protection from the effects of pathogenic microflora of objects in contact with textile materials. The most promising approach in the finishing process is the use of dyes or textile auxiliaries, the bactericidal activity of which is known and sufficiently investigated. An analysis of modern preparations, known in medicine as bactericidal or antiseptic, shows that many of them are similar in structure and other characteristics to preparations widely used in textile chemistry as intensifiers of the dyeing process of synthetic fibrous materials.

This work is devoted to the study of the processes of dyeing hydrophobic textile materials with dispersed dyes using preparations with antibacterial properties (triclosan, hydroquinone, resorcinol, β-naphthol) as intensifiers.

As a result of the work carried out, the influence of the nature and concentration of preparations on the color characteristics of fabrics and the kinetics of dyeing processes was studied; the optimal method of processing materials with the strongest intensifier – triclosan – was selected.

The obtained results indicate the possibility of using considered representatives of phenols, which have antibacterial properties, as intensifiers for dyeing polyester, polyamide and acetate fabrics. This will increase the selection of dyes, reduce the dyeing temperatures and at the same time impart biocidal properties to fabrics, thereby reducing the stages of final finishing.
