摘要
We report synthesis and performance evaluation of a series of novel acid dyes based on diazotized substituted aryl amines and employing substituted naphthalene sulfonic acids as coupling component. The synthesized dyes were thoroughly characterized using UV-visible, IR, (HNMR)-H-1 spectroscopy. elemental analysis and negative MALDI-TOF mass spectrometric analysis. The effectiveness of these dyes was evaluated by applying them on wool fabric using a standard exhaust dyeing procedure. The results for washing, light, perspiration and rubbing fastness of the dyed fabric demonstrate excellent fixation, binding strength and fastness properties which indicate that they are suitable for industrial wool dyeing operations.
