| Résumé : |
The development of a new range of dyestuffs requires a large amount of both synthetic and application work. In order to reduce the number of experiments, it was necessary to develop tools that can give in advance an idea about some properties of the designed dyestuffs. Based on previous theoretical studies, an empirical formula was used to develop a new range of compatible dyestuffs with high fastness. This formula defined the socalled WHAI value, which is obtained by the divison of the molecular weight by the number of azo and ionic groups and the hydrophobicity of the dye. This approach is useful for synthesizing both metal and non metal complex dyes. The new dyes were screened with spectrophotometric measurements, dyeing on leather fibres, physical property measurements (solubility, stability to acids and alkalis...), leather dyeings, fastness and range combinability. Results shown in a previous communication are expanded with three new dyes, one of them being a non-metal complex. The application results showw the ability of the new range to obtain almost all the possible shades in deep, level dyeings. |
