| Abstract | ||
| Abstract Some disperse dyes were prepared and applied in dyeing the 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%. One method of dye bath reuse is to reconstitute the dye bath by adding the required amount of dyes and chemicals to prevent and reduce the contamination. The dye bath reuse has long been recognized as a strategy to prevent pollution and reduction of cost. During low temperature dyeing of PET fibers, carriers are used for improvement adsorption and acceleration of the dispersal of dyes dispersed in the fibers. 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. | ||
