| Abstract | ||
| Some disperse dyes were prepared and applied in dyeing polyester fabrics in an attempt to compare dyeing at low temperatures and high temperatures by studying the dye uptake. Also, the optimal dispersing agent ratio for both methods was studied, which ranged from 0.5 to 2%. . Finally, the fastness properties were evaluated for two dyeing methods represented by light fastness, washing fastness, rubbing fastness and perspiration fastness, where very good results were obtained, except for light fastness, the results were satisfactory | ||
