The effect of a polycyclic structure on a color that is calorically resistant to influences

The purpose of the work was to study the influence of polycyclic structure as an additive on thermodynamic parameters of dyeing systems. The dyeing process of cotton textile material using direct dye was investigated. Methods . Various methods were used in the experimental studies to achieve the objective. Physical methods were used to study the properties of dyeing solutions. The quality of fabric preparation was evaluated by capillarity value. IR and UV spectroscopy methods were used to study the solutions. Cross sections of the stained materials were studied using the microscopic method. The methods defined for this type of products were used to evaluate the quality of coloring resistance to physicochemical and physical-mechanical influences. Results . The process of dyeing of cotton textile materials with direct turquoise lightfast dye in dyeing solutions containing classical components of dyeing formulation and in solutions with 1,2,4-triazine additive is considered. Kinetic dependences of the content and sorption of direct turquoise lightfast dye by cotton textile material under the investigated conditions have been obtained. A comparative study of the resistance of the obtained color of cotton material to various types of chemical and mechanical influences was carried out. The results obtained during dyeing with a direct turquoise light-resistant dye in the presence of a triazine functional additive show that not only chemical intensification of the coloring process is observed, but also a change in the color stability to certain types of influences. Conclusion . It is revealed that the introduction of polycyclic structure in the form of 1,2,4-triazine additive into the dyeing composition has a positive effect on the process of sorption of direct turquoise lightfast dye by textile materials of cellulose nature and increases resistance to various kinds of physical-chemical and physical-mechanical influences.
