| Abstract | ||||
| Fabrics treated with many chemicals and different technologies to give them good functional properties. In this study, new coloured materials were prepared and used for colouring and finishing fabrics in one step. Pyrimidine derivatives are compounds that have attracted much attention in recent years because of their broad spectrum of biological activities.We have synthesized various pyrimidine derivatives such as aminothioxopyrido (2,3-d) pyrimidine derivatives as coloured materials, which are used in dyeing different textile materials. The effect of the nature of various substituents on this type of pyrimidine derivatives as dye (new coloured materials) behavior has been studied on various types of textiles; all synthesized compounds were examined for their dyeing properties on different fabrics such as wool, acrylic, viscose and polyester fabrics. The chemical structures of the synthesized compound 1-3 have been elucidated by spectroscopic data analysis and are in good agreement with the proposed structures. Moreover, the colour strength was examined in detail. The colour strength of dyed textiles and the fastness of the compounds were determined. Wool fabrics got better dyeability than other fabrics. The effect of pH dyeing bath, dyeing temperature and dye concentration for the new coloured (amino-thioxopyrido (2,3-d) -pyrimidine derivatives) were studied. In addition, the effects of the properties of the new coloured materials on the performance of woolen garments were identified and some properties of coloured fabrics such as weight, thickness, roughness, air permeability, thermal insulation and bending modulus examined. The moisture transport property was measured by a wicking test in the vertical and horizontal directions. The treated fabric exhibited excellent ultraviolet protection without significant discrepancy in its inherent physico-mechanical properties. The effect of new dyes on the performance characteristics of woolen garments was evaluated using a radar chart. | ||||
