Abstract

A series of novel monoazo disperse dyes based on naphthalimide containing butyric acid have been applied on the wool fabric. The build up and dyeing properties of these dyes such as leveling property, wash, light, perspiration for alkaline and acidic conditions and rubbing fastnesses on wool fabrics were investigated. The results showed that the applied dyes are capable to produce red to bluish red hues on wool fabrics. Due to the presence of carboxylic acid and hydroxyl groups on the molecular structure of dye 4, it showed favorable and higher chroma with respect to other used dyes. Comparing the build up the dyes with commercial disperse red 60 and disperse red 73 revealed that they are superior to the commercial ones. Measurement of fastnesses properties of dyed samples indicated that they have good wash (4-5), rubbing (4-5), perspiration (4-5) and moderate light fastnesses.
