“…Oil crisis in 1970s led to a sharp increment in costs of raw materials for production of dyestuffs. This created a force toward lower cost dyestuffs by enhancing the production procedures and by replacing dyes of low color strength, such as anthraquinone derivatives, with higher color strength dyes, such as heterocyclic dyes [22][23][24][25][26][27][28].…”

“…Ashkar et al [ 24 ], Sakoma et al [ 25 ] El-Apasery et al [ 26 ], and Al-Etaibi et al [ 27 ] have evaluated 3-( p -substituted phenylazo)-6-pyridone dyes 14a–d , 14e–n , 14o,p and 14q–w , respectively, as potential disperse dyes that exist in the hydrazone tautomeric form as shown in Figure 2 for the dyes 14q , 14r and 14w and applied them on polyester fabrics, to analyze the impact of substituents on the shade of the synthesized dyes.…”

“…Ashkar et al [ 24 ], Sakoma et al [ 25 ], and El-Apasery et al [ 26 ] reported that the exhaustion of the colors was generally excellent on polyester fabrics, with acceptable wash and light fastness properties. These dyes are essential for their excellent affinity for fabrics.…”

“…High temperature dyeing is the most extensive strategy for batch coloration, grants increased diffusion, and along these lines, the expanded rate of dyeing by lessening the union between the polymer chains increasing the kinetic energy of the dye molecules [1][2][3]. Environmental problems are related to the dye baths utilized with a wide scope of various components added to the dye bath, regularly at high concentrations.…”
